Changelog

2.0 Beta 15.0 (October 07, 2016)

Introduce support for Post Meta, Term Meta, User Meta, and Comment Meta in their parent endpoints.

For your meta fields to be exposed in the REST API, you need to register them. WordPress includes a register_meta() function which is not usually required to get/set fields, but is required for API support.

To register your field, simply call register_meta and set the show_in_rest flag to true. Note: register_meta must be called separately for each meta key.

(props @rmccue, @danielbachhuber, @kjbenk, @duncanjbrown, #2765)
Introduce Settings endpoint.

Expose options to the REST API with the register_setting() function, by passing $args = array( 'show_in_rest' => true ). Note: WordPress 4.7 is required. See changeset [38635][https://core.trac.wordpress.org/changeset/38635].

(props @joehoyle, @fjarrett, @danielbachhuber, @jonathanbardo, @greatislander, #2739)
Attachments controller, change permissions check to match core.

Check for the upload_files capability when creating an attachment.

(props @nullvariable, @adamsilverstein, #2743)
Add ?{taxonomy}_exclude= query parameter

This mirrors our existing support for ?{taxonomy}= filtering in the posts controller (which allows querying for only records with are associated with any of the provided term IDs for the specified taxonomy) by adding an equivalent _exclude variant to list IDs of terms for which associated posts should NOT be returned.

(props @kadamwhite, #2756)
Use get_comment_type() when comparing updating comment status.

Comments having a empty comment_type within WordPress bites us again. Fixes a bug where comments could not be updated because of bad comparison logic.

(props @joehoyle, #2753)

2.0 Beta 14.0 (September 30, 2016)

Add support for password protected posts

Password protected posts are now fully supported, you can create edit and read password protected posts in the REST API. There is now a protected attribute in the content and excerpt fields in post response.

To view password protected posts via the API, use the password query parameter to provide the post's password.

2.0 Beta 13.0 (March 29, 2016)

(props @rmccue, #2239)
BREAKING CHANGE: Use compact links for embedded responses if they are available.

Introduces curies for sites running WordPress 4.5 or greater; no changes for those running WordPress 4.4.

(props @adamsilverstein, #2403)

2.0 Beta 12.0 (February 9, 2016)

BREAKING CHANGE: Removes meta endpoints from primary plugin.

If your project depends on post meta endpoints, please install WP REST API Meta Endpoints. For the gory history of meta, read #1425 and linked issues. At this time, we recommend using register_rest_field() to expose meta (docs).

(props @danielbachhuber, #2172)
BREAKING CHANGE: Returns original resource when deleting PTCU.

Now that all resources require the force param, we don't need to wrap delete responses with the trash state.

(props @danielbachhuber, #2163)
BREAKING CHANGE: Uses roles rather than role in the Users controller.

Building the REST API gives us the opportunity to standardize on roles, instead of having both roles and role.

(props @joehoyle, #2177)
BREAKING CHANGES: Moves to consistent use of context throughout controllers.

Contexts limit the data present in the response. Here's how to think of them: embed correlates with sidebar representation, view represents the primary public view, and edit is the data expected for an editor.

(props @danielbachhuber, #2205, #2204, #2203, #2218, #2216, #2230, #2184, #2235)
BREAKING CHANGE: Removes post_* query param support for GET /wp/v2/comments.

The proper pattern is to use GET /wp/v2/posts to fetch the post IDs to limit the request to.

(props @danielbachhuber, #2165)
BREAKING CHANGE: Introduces rest_validate_request_arg()/rest_sanitize_request_arg().

Dedicated functions means we can use them for validating / sanitizing query args too. Removes WP_REST_Controller::validate_schema_property() and WP_REST_Controller::sanitize_schema_property().

(props @danielbachhuber, #2166, #2213)

Permits viewing of User who has published any Public posts.

(props @danielbachhuber, #2155)
Respects show_avatars option when adding avatars to Users.

(props @nullvariable, #2151)
Controllers use $namespace and $rest_base class variables for easier subclassing.

(props @danielbachhuber, #2119, #2130, #2131, #2132, #2133, #2134, #2139, #2141, #2142)

2.0 Beta 11.0 (January 25, 2016)

BREAKING CHANGE: Moves Post->Term relations to the Post Resource

Previously, a client would fetch a Post's Tags with GET /wp/v2/posts/<id>/tags.

In Beta 11, an array of term ids is included on the Post resource.

The collection of terms for a Post can be fetched with GET /wp/v2/tags?post=<id>.

The WP_REST_Posts_Terms_Controller class no longer exists.

(props @joehoyle, #2063)
BREAKING CHANGE: Adds latest JS client including a minified version.

See pull request for a summarized changelog.

(props @adamsilverstein, #1981)
BREAKING CHANGE: Changes featured_image attribute on Posts to featured_media.

While featuring other attachment types isn't yet officially supported, this makes it easier for us to introduce the possibility in the future.

(props @danielbachhuber, #2044)
BREAKING CHANGE: Uses discrete schema title for categories and tags.

If you've used register_rest_field( 'term' ), you'll need to change 'term' to 'tag' and/or 'category'.

(props @danielbachhuber, #2005)
BREAKING CHANGE: Makes many filters dynamic based on the controller type.

If you were using the rest_prepare_term filter, you'll need to change it to rest_prepare_post_tag or rest_prepare_category.

If you were using rest_post_query or rest_terms_query, you'll need update your use to rest_page_query, etc.

If you were using rest_post_trashable, rest_insert_post or rest_delete_post, they are now dynamic based on the post type slug.

(props @danielbachhuber, #2008, #2010, #2057, #2058)
Renames GET /wp/v2/comments user param to author to match resource attribute.

Not a breaking change, because it didn't work in the first place.

(props @danielbachhuber, #2105)
Adds support for GET /wp/v2/pages parent=1,2,3.

(props @danielbachhuber, #2101)
Persists image metadata title and caption when not present in the request.

(props @danielbachhuber, #2060)
Provides more helpful error message/code on Post Create/Update fail.

(props @danielbachhuber, #2053)
Forces GET /wp/v2/media to be limited to 'status' => [ inherit, private, trash ]

(props @danielbachhuber, #2026)
Uses more correct error code for Comment::delete permission check.

(props @danielbachhuber, #2054)
Calls prepare_item_for_response() directly in create and update methods.

This lets us pass the original request through, giving the method and its filter genuine context, and avoids an unnecessary call to get_item().

(props @danielbachhuber, #2038, #2040, #2041, #2043, #2042)
Moves permission check methods across controllers.

Placing them above the method they're supposed to check makes the code more readable.

(props @danielbachhuber, #2030, #2029, #2034, #2036, #2037, #2035, #2039)
Requires force argument for DELETE /wp/v2/<taxonomy>/<id>.

Adds helpful description to force param across all DELETE registrations

(props @danielbachhuber, #2004, #2027)
In GET /wp/v2/<taxonomy>, drops support for orderby=>term_id.

Only one id is exposed through the REST API.

(props @danielbachhuber, #1990)

SECURITY: Ensure media of private posts are private too.

Reported by @danielbachhuber on 2016-01-08.
BREAKING CHANGE: Removes compatibility repo for WordPress 4.3.

WordPress 4.4 is now the minimum supported WordPress version.

(props @danielbachhuber, #1848)
BREAKING CHANGE: Changes link relation for types and taxonomies.

In Beta 9, this link relation was introduced as item, which isn't correct. The relation has been changed to https://api.w.org/items.

(props @danielbachhuber, #1853)
BREAKING CHANGE: Introduces edit context for wp/v2/types and wp/v2/taxonomies.

Some fields have moved into this context, which require edit_posts and manage_terms, respectively.

(props @danielbachhuber, #1894, #1864)
BREAKING CHANGE: Removes post_format as a term _link for Posts.

Post formats aren't a custom taxonomy in the eyes of the REST API.

(props @danielbachhuber, #1854)
Declares parent query param for Pages.

(props @danielbachhuber, #1975)
Permits logged-in users to query for media.

Adds include param to /wp/v2/posts, /wp/v2/users, /wp/v2/<taxonomy> and /wp/v2/comments.

(props @danielbachhuber, #1961, #1964, #1968, #1971)
Ensures GET /wp/v2/posts respects order and orderby params.

(props @danielbachhuber, #1962)
Fixes fatal by loading wp-admin/includes/user.php to expose wp_delete_user().

(props @danielbachhuber, #1958)
Permits making a post sticky when also supplying an empty password.

(props @westonruter, #1949)
Uses WP_REST_Request internally across controllers.

Prevents error notice when show_in_rest isn't set for a post type.

(props @danielbachhuber, #1852)

2.0 Beta 9.0 (December 11, 2015)

BREAKING CHANGE: Move tags and categories to top-level endpoints.

Tags are now accessible at /wp/v2/tags, and categories accessible at /wp/v2/categories. Post terms reside at /wp/v2/posts/<id>/tags and /wp/v2/<id>/categories.

(props @danielbachhuber, #1802)
BREAKING CHANGE: Return object for requests to /wp/v2/taxonomies.

This is consistent with /wp/v2/types and /wp/v2/statuses.

(props @danielbachhuber, #1825)
BREAKING CHANGE: Remove rest_get_timezone().

json_get_timezone() was only ever used in v1. This function causes fatals, and shouldn't be used.

(props @danielbachhuber, #1823)
BREAKING CHANGE: Rename register_api_field() to register_rest_field().

Introduces a register_api_field() function for backwards compat, which calls _doing_it_wrong(). However, register_api_field() won't ever be committed to WordPress core, so you should update your function calls.

(props @danielbachhuber, #1824)
BREAKING CHANGE: Change taxonomies' post_type argument to type.

It's consistent with how we're exposing post types in the API.

(props @danielbachhuber, #1824)
Sync infrastructure with shipped in WordPress 4.4.
- wp-includes/rest-api/rest-functions.php is removed, and its functions moved into wp-includes/rest-api.php.
- Send nocache headers for REST requests. #34832
- Fix handling of HEAD requests. #34837
- Mark WP_REST_Server::get_raw_data() as static. #34768
- Unabbreviate error string. #34818
Change terms endpoints to use term_id not tt_id.

(props @joehoyle, #1837)
Standardize declaration of context param for GET requests across controllers.

However, we're still inconsistent in which controllers expose which params. Follow #1845 for further discussion.

(props @danielbachhuber, #1795, #1835, #1838)
Link types / taxonomies to their collections, and vice versa.

Collections link to their type / taxonomy with the about relation; types / taxonomies link to their colletion with the item relation, which is imperfect and may change in the future.

(props @danielbachhuber, #1814, #1817, #1829. #1846)
Add missing 'wp/v2' in Location Response header when creating new Post Meta.

(props @johanmynhardt, #1790)
Expose Post collection query params, including author, order, orderby and status.

(props @danielbachhuber, #1793)
Ignore sticky posts by default.

(props @danielbachhuber, #1801)
Include full image size in attachment sizes attribute.

(props @danielbachhuber, #1806)
In text strings, use id instead of ID.

ID is an implementation artifact. Our Resources use id.

(props @danielbachhuber, #1803)
Ensure attachment.sizes[] use mime_type instead of mime-type.

(props @danielbachhuber, #1809)
Introduce rest_authorization_required_code().

Many controllers returned incorrect HTTP codes, which this also fixes.

Respect core's comment_registration setting.

If it's enabled, require users to be logged in to comment.

(props @danielbachhuber, #1826)
Default to wildcard when searching users.

Prevent fatals when uploading attachment by including admin utilities.

(props @danielbachhuber, #1756)
Return 201 status code when creating a term.

(props @danielbachhuber, #1753)
Don't permit requesting terms cross routes.

Clients should only be able to request categories from the category route, and tags from the tag route.

(props @danielbachhuber, #1764)
Set fields=>id when using WP_User_Query to fix large memory usage

(props @joehoyle, #1770)
Fix Post _link to attached attachments.

(props @danielbachhuber, #1777)
Add support for getting a post with a custom public status.

(props @danielbachhuber, #1765)
Ensure post content doesn't get double-slashed on update.

(props @joehoyle, #1772)
Change 'int' to 'integer' for WP_REST_Controller::validate_schema_property()

(props @wpsmith, #1759)

2.0 Beta 7.0 (November 17, 2015)

Sync infrastructure from WordPress core as of r35691.
- Remove register_api_field() because it's conceptually tied to WP_REST_Controller #34730

2.0 Beta 6.0 (November 12, 2015)

Remove global inclusion of wp-admin/includes/admin.php

For a long time, the REST API loaded wp-admin/includes/admin.php to make use of specific admin utilities. Now, it only loads those admin utilities when it needs them.

If your custom endpoints make use of admin utilities, you'll need to make sure to load wp-admin/includes/admin.php before you use them.

2.0 Beta 5.0 (October 23, 2015)

Load api-core as a compatibility library

Now api-core has been merged into WordPress trunk (for 4.4) we should no longer load the infrastructure code when it's already available. This also fixes a fatal error for users who were on trunk.

(props @joehoyle)

2.0 Beta 4.0 (August 14, 2015)

Show public user information through the user controller.

In WordPress as of r32683 (scheduled for 4.3), WP_User_Query now has support for getting users with published posts.

To match current behaviour in WordPress themes and feeds, we now expose this public user information. This includes the avatar, description, user ID, custom URL, display name, and URL, for users who have published at least one post on the site. This information is available to all clients; other fields and data for all users are still only available when authenticated.

(props @joehoyle, @rmccue, @Shelob9, #1397, #839, #1435)
Send schema in OPTIONS requests and index.

Rather than using separate /schema endpoints, the schema for items is now available through an OPTIONS request to the route. This means that full documentation is now available for endpoints through an OPTIONS request; this includes available methods, what data you can pass to the endpoint, and the data you'll get back.

This data is now also available in the main index and namespace indexes. Simply request the index with context=help to get full schema data. Warning: this response will be huge. The schema for single endpoints is also available in the collection's OPTIONS response.

⚠️ This breaks backwards compatibility for clients relying on schemas being at their own routes. These clients should instead send OPTIONS requests.

Custom endpoints can register their own schema via the schema option on the route. This option should live side-by-side with the endpoints (similar to relation in WP's meta queries), so your registration call will look something like:
```
register_rest_route( 'test-ns', '/test', array(
  array(
    'methods' => 'GET',
    'callback' => 'my_test_callback',
  ),

  'schema' => 'my_schema_callback',
) );
```
(props @rmccue, #1415, #1222, #1305)
Update JavaScript API for version 2.

Our fantastic JavaScript API from version 1 is now available for version 2, refreshed with the latest and greatest changes.

As a refresher: if you want to use it, simply make your script depend on wp-api when you enqueue it. If you want to enqueue the script manually, add wp_enqueue_script( 'wp-api' ) to a callback on wp_enqueue_scripts.

(props @tlovett1, @kadamwhite, @nathanrice, #1374, #1320)
Embed links inside items in a collection.

Previously when fetching a collection of items, you only received the items themselves. To fetch the links as well via embedding, you needed to make a request to the single item with _embed set.

No longer! You can now request a collection with embeds enabled (try /wp/v2/posts?_embed). This will embed links inside each item, allowing you to build interface items much easier (for example, post archive pages can get featured image data at the same time).

This also applies to custom endpoints. Any endpoint that returns a list of objects will automatically have the embedding applied to objects inside the list.

(props @rmccue, #1459, #865)
Fix potential XSS vulnerability.

Requests from other origins could potentially run code on the API domain, allowing cross-origin access to authentication cookies or similar.

Reported by @xknown on 2015-07-23.
Move /posts WP_Query vars back to filter param.

In version 1, we had internal WP_Query vars available via filter (e.g. filter[s]=search+term). For our first betas of version 2, we tried something different and exposed these directly on the endpoint. The experiment has now concluded; we didn't like this that much, so filter is back.

We plan on adding nicer looking arguments to collections in future releases, with a view towards being consistent across different collections. We also plan on opening up the underlying query vars via filter for users, comments, and terms as well.

⚠️ This breaks backwards compatibility for users using WP Query vars. Simply change your x=y parameter to filter[x]=y.

(props @WP-API, #1420)
Respect rest_base for taxonomies.

⚠️ This breaks backwards compatibility by changing the /wp/v2/posts/{id}/terms/post_tag endpoint to /wp/v2/posts/{id}/tag.

(props @joehoyle, #1466)
Add permission check for retrieving the posts collection in edit context.

By extension of the fact that getting any individual post yields a forbidden context error when the context=edit and the user is not authorized, the user should also not be permitted to list any post items when unauthorized.

(props @danielpunkass, #1412)
Ensure the REST API URL always has a trailing slash.

Previously, when pretty permalinks were enabled, the API URL during autodiscovery looked like /wp-json, whereas the non-pretty permalink URL looked like ?rest_route=/. These are now consistent, and always end with a slash character to simplify client URL building.

(props @danielpunkass, @rmccue, #1426, #1442, #1455, #1467)
Use wp_json_encode instead of json_encode

Since WordPress 4.1, wp_json_encode has been available to ensure encoded values are sane, and that non-UTF8 encodings are supported. We now use this function rather than doing the encode ourselves.

(props @rmccue, @pento, #1417)
Add role to schema for users.

The available roles you can assign to a user are now available in the schema as an enum.

(props @joehoyle, #1400)
Use the schema for validation inside the comments controller.

Previously, the schema was merely a decorative element for documentation inside the comments controller. To bring it inline with our other controllers, the schema is now used internally for validation.

(props @joehoyle, #1422)
Don't set the Location header in update responses.

Previously, the Location header was sent when updating resources due to some inadvertent copypasta. This header should only be sent when creating to direct clients to the new resource, and isn't required when you're already on the correct resource.

(props @rachelbaker, #1441)
Re-enable the rest_insert_post action hook for WP_REST_Posts_Controller

This was disabled during 2.0 development to avoid breaking lots of plugins on the json_insert_post action. Now that we've changed namespaces and are Mostly Stable (tm), we can re-enable the action.

(props @jaredcobb, #1427, #1424)
Fix post taxonomy terms link URLs.

When moving the routes in a previous beta, we forgot to correct the links on post objects to the new correct route. Sorry!

(props @rachelbaker, @joehoyle, #1447, #1383)
Use wp_get_attachment_image_src() on the image sizes in attachments.

Since the first versions of the API, we've been building attachment URLs via str_replace. Who knows why we were doing this, but it caused problems with custom attachment URLs (such as CDN-hosted images). This now correctly uses the internal functions and filters.

(props @joehoyle, #1462)
Make the embed context a default, not forced.

If you want embeds to bring in full data rather than with context=edit, you can now change the link to specify context=view explicitly.

(props @rmccue, #1464)
Ensure we always use the term_taxonomy_id and never expose term_id publicly.

Previously, term_id was inadvertently exposed in some error responses.

(props @jdolan, #1430)
Fix adding alt text to attachments on creation.

Previously, this could only be set when updating an attachment, not when creating one.

(props @joehoyle, #1398)
Throw an error when registering routes without a namespace.

Namespaces should always be provided when registering routes. We now throw a doing_it_wrong error when attempting to register one. (Previously, this caused a warning, or an invalid internal route.)

If you really need to register namespaceless routes (e.g. to replicate an existing API), call WP_REST_Server::register_route directly rather than using the convenience function.

(props @joehoyle, @rmccue, #1355)
Show links on embeds.

Previously, links were accidentally stripped from embedded response data.

(props @rmccue, #1472)
Clarify insufficient permisssion error when editing posts.

Improve @return inline docs for rest_ensure_response()

2.0 Beta 2.0 (May 28, 2015)

Load the WP REST API before the main query runs.

The rest_api_loaded function now hooks into the parse_request action. This change prevents the main query from being run on every request and allows sites to set WP_USE_THEMES to false. Previously, the main query was always being run (SELECT * FROM wp_posts LIMIT 10), even though the result was never used and couldn't be cached.

(props @rmccue, [#1270][gh-1270])
Register a new field on an existing WordPress object type.

Introduces register_api_field() to add a field to an object and its schema.

List registered namespaces in the index for feature detection.

The index (/wp-json by default) now contains a list of the available namespaces. This allows for simple feature detection. You can grab the index and check namespaces for wp/v3 or pluginname/v2, which indicate the supported endpoints on the site.

(props @rmccue,, [#1283][gh-1283])
Standardize link property relations and support embedding for all resources.

Change link properties to use IANA-registered relations. Also adds embedding support to Attachments, Comments and Terms.

(props @rmccue, @rachelbaker, [#1284][gh-1284])
Add support for Composer dependency management.

Allows you to recursively install/update the WP REST API inside of WordPress plugins or themes.

1.2.1

Fix information disclosure security vulnerability.

Unauthenticated users could access revisions of published and unpublished posts. Revisions are now only accessible to authenticated users with permission to edit the revision's post.

Reported by @chredd on 2015-04-09.

1.2.0

Add handling for Cross-Origin Resource Sharing (CORS) OPTIONS requests.

Preflighted requests (using the OPTIONS method) include the headers Access-Control-Allow-Origin, Access-Control-Allow-Methods, and Access-Control-Allow-Credentials in the response, if the HTTP origin is set.

(props @rmccue, #281)
Allow overriding full requests.

The json_pre_dispatch filter allows a request to be hijacked before it is dispatched. Hijacked requests can be anything a normal endpoint can return.

(props @rmccue, #281)
Check for JSON encoding/decoding errors.

Returns the last error (if any) occurred during the last JSON encoding or decoding operation.

(props @joshkadis, @rmccue, #461)
Add filtering to the terms collection endpoint.

Available filter arguments are based on the get_terms() function. Example: /taxonomies/category/terms?filter[number]=10 would limit the response to 10 category terms.

(props @mauteri, #401, #347)
Add handling for the role parameter when creating or updating a user.

Allow users to be created or updated with a provided role.

(props @pippinsplugins, #392, #335)
Add handling for the post_id parameter when creating media.

Allow passing the post_id parameter to associate a new media item with a post.

(props @pkevan, #294)
Handle route matching for - in taxonomy and terms.

Previously the regular expression used to match taxonomy and term names did not support names with dashes.

(props @EdHurtig, @evansobkowicz, #410)
Handle JSONP callback matching for . in the function name.

Previously the regular expression used to match JSONP callback functions did not support names with periods.

(props @codonnell822, #455)
Fix the Content-Type header for JSONP requests.

Previously JSONP requests sent the incorrect application/json Content-Type header with the response. This would result in an error if strict MIME checking was enabled. The Content-Type header was corrected to application/javascript for JSONP responses.

(props @simonlampen, #380)
Add $context parameter to json_prepare_term filter.

Terms responses can now be modified based on the context parameter of the request.

(props @traversal, #316)
Move the JavaScript client library into the plugin.

Previously, the wp-api.js file was a separate repository. The JavaScript client has moved back into the plugin to coordinate code changes.

(props @tlovett1, #730)
Always return an object for media sizes

The media sizes value should always be an object even when empty. Previously, if a media item did not have any sizes set, an empty array was returned.

Compatibility warning: Clients should be prepared to accept an empty object as a value for media sizes.

(props @maxcutler, #300)
Give top-level posts a null parent value.

For date type consistency, post parent property should be null. Previously, parent-less posts returned 0 for parent.

Compatibility warning: Clients should be prepared to accept null as a value for post parent.

(props @maxcutler, #391)
Move permission checks out of WP_JSON_Posts.

Introduce json_check_post_permission() function to allow post object capability checks to be used outside the WP_JSON_Posts class.

Deprecation warning: Calling WP_JSON_Posts::check_read_permission and WP_JSON_Posts::check_edit_permission is now deprecated.

(props @rachelbaker, #486, #378)
Split comment endpoints into separate class.

All comment handling has moved to the WP_JSON_Comments class.

Deprecation warning: Calling WP_JSON_Posts::get_comments, WP_JSON_Posts::get_comment, WP_JSON_Posts::delete_comment, and WP_JSON_Posts::prepare_comment is now deprecated.

(props @whyisjake, @rmccue, @rachelbaker, #378)
Split meta endpoints into separate class.

All post meta handling has moved to the new WP_JSON_Meta_Posts class.

Deprecation warning: Calling WP_JSON_Posts::get_all_meta, WP_JSON_Posts::get_meta, WP_JSON_Posts::update_meta, WP_JSON_Posts::add_meta, WP_JSON_Posts::delete_meta, WP_JSON_Posts::prepare_meta, and WP_JSON_Posts::is_valid_meta_data is now deprecated.

(props @rmccue, @rachelbaker, #358, #474)
Rename internal create methods.

Deprecation warning: Calling WP_JSON_Posts::new_post, WP_JSON_CustomPostType::new_post and WP_JSON_Posts::new_post is now deprecated.

(props @rachelbaker, @rmccue, #374, #377, #376)
Fix discrepancies in edit and create posts documentation examples.

Corrected the edit and create posts code examples in the Getting Started section. The new post example was updated to include the required content_raw parameter. The new and edit posts examples were updated to use a correct date parameter.

(props @rachelbaker, #305)
Update the cookie authentication documentation examples.

With 1.1 the localized JavaScript object for wp-api.js changed to WP_API_Settings. This updates the Authentication section documentation nonce example to use the updated object name.

(props @rachelbaker, #321)
Add flexibility and multisite support to unit tests.

Tests can be run from any WordPress install, and are not limited to only as a plugin installed within a WordPress.org develop checkout. Unit tests are now run against a multisite installation.

(props @danielbachhuber, #397)

(props @markoheijnen, #437)

1.1.1

Mitigate Flash CSRF exploit

Using the API's JSONP support, it's possible to control the first bytes of the response sent to the browser. Combining this with an ASCII-encoded SWF allows arbitrary SWFs to be served from the site, allowing bypassing the same-origin policy built in to browsers.

While the API includes CSRF protection and is not directly vulnerable, this can be used to bypass other browser origin controls.

Reported by @iandunn on 2014-07-10.

(props @iandunn, @rmccue, #356)

1.1

Add new routes for taxonomies and terms.

Taxonomies and terms have now been moved from the /posts/types/<type> namespace to global routes: /taxonomies, /taxonomies/<tax>, /taxonomies/<tax>/terms and /taxonomies/<tax>/terms/<term>

Test coverage for taxonomy endpoints has also been increased to 100%.

Deprecation warning: The /posts/types/<type>/taxonomies endpoint (and sub-endpoints with the same prefix) have been deprecated in favour of the new endpoints. These deprecated endpoints will now return a X-WP-DeprecatedFunction header indicating that the endpoint should not be used for new development, but will continue to work in the future.

(props @kadamwhite, @rachelbaker, @rmccue, #198, #211)
Allow customizing the API resources prefix

The API base (typically wp-json/) can now be customized to a different prefix using the json_url_prefix filter. Note that rewrites will need to be flushed manually after changing this.

(props @ericandrewlewis, @rmccue, #104, #244, #278)
Give null as date for draft posts.

Draft posts would previously return "0000-00-00 00:00:00" or "1970-01-01T00:00:00", as draft posts are not assigned a publish date. The API now returns null where a date is not available.

Compatibility warning: Clients should be prepared to accept null as a value for date/time fields, and treat it as if no value is set.

(props @rmccue, #229, #230)
Fix errors with excerpt.

Posts without excerpts could previously return nonsense strings, excerpts from other posts, or cause internal PHP errors. Posts without excerpts will now always return an excerpt, typically automatically generated from the post content.

The excerpt_raw field was added to the edit context on posts. This field contains the raw excerpt data saved for the post, including empty string values.

(props @rmccue, #222, #226)
Only expose email for edit context.

User email addresses are now only exposed for context=edit, which requires the edit_users permission (not required for the current user).

The email address field will now return false instead of a string if the field is not exposed.

(props @pkevan, @rmccue, #290, #296)
Correct password-protected post handling.

Password-protected posts could previously be exposed to all users, however could also have broken behaviour with excerpts. Password-protected posts are now hidden to unauthenticated users, while content and excerpts are shown correctly for the edit context.

(Note that hiding password-protected posts is intended to be a temporary measure, and will likely change in the future.)

(props @rmccue, #286, #313)
Add documentation on authentication methods.

Full documentation on authentication is now available. This documentation explains the difference between the various available authentication methods, and notes which should be used.

(props @rmccue, #242)
Include new client JS from github.io

The WP-API Javascript library is now loaded dynamically from wp-api.github.io to ensure it is always up-to-date.

(props @tlovett1, #179, #240)
Don't allow setting the modification date on post creation/update.

As it turns out, WP core doesn't allow us to set this, so this was previously a no-op anyway. Discovered during test coverage phase.

(props @rachelbaker, @rmccue, #285, #288)
Check post parent correctly on insertion.

Posts could previously be added with an invalid parent ID. These IDs are now checked to ensure the post exists.

(props @rmccue, #228, #231)
Make sure the type is actually evaluated for json_prepare_${type} filter.

This value was previously not interpolated correctly, due to the use of the single-quoted string type.

(props @danielbachhuber, #266)
Return WP_Error instead of array of empty objects for a revisions permissions error.

Previously, when trying to access post revisions without correct permissions, a JSON list of internal error objects would be returned. This has been corrected to return a standard API error instead.

(props @rachelbaker, @tlovett1, #251, #276)
Flip user parameters check for insert/update.

Previously, you could add a user without specifying username/password/email, but couldn't update a user without those parameters. The logic has been inverted here instead.

(props @rmccue, #221, #289)
Add revision endpoints tests

(props @danielbachhuber, @rachelbaker, @rmccue, #275, #277, #284, #279)
Add post endpoint testing

Now at >54% coverage for the whole class, and >80% for the main methods. This figure will continue to rise over the next few releases.

(props @rachelbaker, @rmccue, #99)
Separate helper functions into global namespace.

WP_JSON_Server::get_timezone(), WP_JSON_Server::get_date_with_gmt(), WP_JSON_Server::get_avatar_url() and ``WP_JSON_Server::parse_date()` have all been moved into the global namespace to decouple them from the server class.

Deprecation warning: These methods have been deprecated. The new json_get_timezone(), json_get_date_with_gmt(), json_get_avatar_url() and json_parse_date() methods should now be used instead.

(props @rmccue, #185, #298)

1.0

Add user endpoints.

Creating, reading, updating and deleting users and their data is now possible by using the /users endpoints. /users/me can be used to determine the current user, and returns a 401 status for non-logged in users.

Note that the format of post authors has changed, as it is now an embedded User entity. This should not break backwards compatibility.

Custom post types gain this ability automatically.

(props @tobych, @rmccue, #20, #146)
Add post meta endpoints.

Creating, reading, updating and deleting post meta is now possible by using the /posts/<id>/meta endpoints. Post meta is now correctly embedded into Post entities.

Meta can be updated via the Post entity (e.g. PUT to /posts/<id>) or via the entity itself at /posts/<id>/meta/<mid>. Meta deletion must be done via a DELETE request to the latter.

Only non-protected and non-serialized meta can be accessed or manipulated via the API. This is not predicted to change in the future; clients wishing to access this data should consider alternative approaches.

Custom post types do not currently gain this ability automatically.

(props @attitude, @alisspers, @rachelbaker, @rmccue, @tlovett1, @tobych, @zedejose, #68, #168, #189, #207)
Add endpoint for deleting a single comment.

Clients can now send a DELETE request to comment routes to delete the comment.

Custom post types supporting comments will gain this ability automatically.

(props @tlovett1, @rmccue, #178, #191)
Add endpoint for post revisions.

Post revisions are now available at /posts/<id>/revisions, and are linked in the meta.links.version-history key of post entities.

Custom post types supporting revisions will gain this ability automatically.

(props @tlovett1, #193)
Respond to requests without depending on pretty permalink settings.

For sites without pretty permalinks enabled, the API is now available from ?json_route=/. Clients should check for this via the autodiscovery methods (Link header or RSD).

(props @rmccue, #69, #138)
Add register post type argument.

Post types can now indicate their availability via the API using the show_in_json argument passed to register_post_type. This value defaults to the publicly_queryable argument (which itself defaults to the public argument).

(props @iandunn, @rmccue, #145)
Remove basic authentication handler.

This breaks backwards compatibility for clients using Basic authentication. Clients are encouraged to switch to using OAuth authentication. The Basic Authentication plugin can be installed for backwards compatibility and local development, however should not be used in production.

(props @rmccue, #37, #152)
Require nonces for cookie-based authentication.

This breaks backwards compatibility and requires any clients using cookie authentication to also send a nonce with the request. The built-in Javascript API automatically handles this.

(props @rmccue, #177, #180)
Clean up deprecated methods/functions.

Functions and methods previously deprecated in 0.8/0.9 have now been removed. Future deprecations will take place in the same manner as WordPress core.

This breaks backwards compatibility, however these were marked as deprecated in previous releases.

(props @rmccue, #187)
Only expose meta on 'edit' context as a temporary workaround.

Privacy concerns around exposing meta to all users necessitate this change.

This breaks backwards compatibility as post meta data is no longer available to all users. Clients wishing to access this data should authenticate and use the edit context.

(props @iandunn, @rmccue, #135)
Add json_ensure_response function to ensure either a WP_JSON_ResponseInterface or a WP_Error object is returned.

When extending the API, the json_ensure_response function can be used to ensure that any raw data returned is wrapped with a WP_JSON_Response object. This allows using get_status/get_data easily, however WP_Error must still be checked via is_wp_error.

(props @rmccue, #151, #154)
Use version option to check on init if rewrite rules should be flushed.

Rewrite rules on multisite are now flushed via an init hook, rather than switching to each site on activation.

(props @rachelbaker, #149)
Fix typo in schema docs

(props @codebykat, #132)
Add check for valid JSON data before using to avoid parameter overwrite.

When passing data to an endpoint that accepts JSON data, the data will now be validated before passing to the endpoint.

(props @rachelbaker, @rmccue, #133)
Add authentication property to site index.

(props @rmccue, #131)
Move the test helper to a subdirectory.

The plugin will now no longer prompt for updates due to the helper.

(props @rmccue, #127)
Include post ID with json_prepare_meta filter.

(props @rmccue, #137)
Corrected parameter names in x-form examples in docs.

(props @rachelbaker, #134)
Pass WP_JSON_Server instance to json_serve_request.

(props @alisspers, @rmccue, #61, #139)
Don't use deprecated function in WP_JSON_Posts::edit_post()

(props @rachelbaker, #150)
Pass post ID to json_insert_post action during both insert and update.

(props @cmmarslender, #148)
Add descriptions to taxonomy term data.

(props @pushred, #111)
Ensure we handle raw data passed to the API.

(props @tlovett1, @rmccue, #91, #155)
Remove unused prepare_author method from WP_JSON_Posts class.

(props @rachelbaker, #165)
Add multiple post type support to get_posts method.

(props @rmccue, #142, #163)
Return WP_Error in WP_JSON_Posts::get_comment for invalid comments.

(props @tlovett1, #166, #171)
Update getting started documentation.

(props @rmccue, #176)
Improve and clarify "array" input syntax documentation.

(props @rmccue, #140, #175)
Update post routes documentation.

(props @rmccue, #172, #174)
Add documentation for user endpoints.

(props @rachelbaker, @rmccue, #158)
Add permalink settings step to Quick Setup instructions.

(props @kadamwhite, #183)
Update taxonomy collection to return indexed array.

(props @mattheu, #184)
Remove placeholder endpoints.

(props @rmccue, #161, #192)
Fix issues with embedded attachments.

Checks that the post supports attachment data before adding it, and ensures we don't embed entities many layers deep.

(props @rmccue, #194)
Change post parent preparation context to embed.

(props @rmccue, #195)
Change server meta links to reference the WP-API organization GitHub repo.

(props @rachelbaker, #208)
Fix plugin tests

(props @rmccue, #215)
Check for errors with invalid dates and remove duplicate date parsing methods.

(props @rachelbaker, @rmccue, #216, #219)

Move from wp-json.php/ to wp-json/

This breaks backwards compatibility and requires any clients to now use wp-json/, or preferably the new RSD/Link headers.

(props @rmccue, @matrixik, #46, #96, #106)
Move filter registration out of CPT constructor. CPT subclasses now require you to call $myobject->register_filters(), in order to move global state out of the constructor.

This breaks backwards compatibility and requires any subclassing to now call $myobject->register_filters()

(props @rmccue, @thenbrent, #42, #126)
Introduce Response/ResponseInterface

Endpoints that need to set headers or response codes should now return a WP_JSON_Response rather than using the server methods. WP_JSON_ResponseInterface may also be used for more flexible use of the response methods.

Deprecation warning: Calling WP_JSON_Server::header, WP_JSON_Server::link_header and WP_JSON_Server::query_navigation_headers is now deprecated. This will be removed in 1.0.

(props @rmccue, #33)
Change all semiCamelCase names to underscore_case.

Deprecation warning: Any calls to semiCamelCase methods require any subclassing to update method references. This will be removed in 1.0.

(props @osiux, #36, #82)
Add multisite compatibility. If the plugin is network activated, the plugin is now activated once-per-site, so wp-json/ is always site-local.

(props @rachelbaker, #48, #49)
Add RSD and Link headers for discovery

(props @rmccue, #40)
WP_JSON_Posts->prepare_author() now verifies the $user object is set.

(props @rachelbaker, #51, #54)
Added unit testing framework. Currently only a smaller number of tests, but we plan to increase this significantly as soon as possible.

(props @tierra, @osiux, #65, #76, #84)
Link collection filtering docs to URL formatting guide.

(props @kadamwhite, #74)
Remove hardcoded /pages references from WP_JSON_Pages

(props @rmccue, @thenbrent, #28, #78)
Fix compatibility with DateTime::createFromFormat on PHP 5.2

(props @osiux, #52, #79)
Document that WP_JSON_CustomPostType::__construct() requires a param of type WP_JSON_ResponseHandler.

(props @tlovett1, #88)
Add timezone parameter to WP_JSON_DateTime::createFromFormat()

(props @royboy789, @rachelbaker, #85, #87)
Remove IXR references. IXR_Error is no longer accepted as a return value.

This breaks backwards compatibility and requires anyone returning IXR_Error objects to now return WP_Error or WP_JSON_ResponseInterface objects.

(props @rmccue, #50, #77)
Fix bugs with attaching featured images to posts:
- WP_JSON_Media::attachThumbnail() should do nothing if $update is false without a post ID
- The post ID must be fetched from the $post array.
(props @Webbgaraget, #55)
Don't declare jsonSerialize on ResponseInterface

(props @rmccue, #97)
Allow JSON post creation/update for WP_JSON_CustomPostType

(props @tlovett1, #90, #108)
Return null if post doesn't have an excerpt

(props @rachelbacker, #72)
Fix link to issue tracker in README

(props @rmccue, @tobych, #125)

Add compatibility layer for JsonSerializable. You can now return arbitrary objects from endpoints and use the jsonSerialize() method to return the data to serialize instead of just using the properties of the object.

(props @rmccue, #24)
Fix page parent links to use /pages

(props @thenbrent, #27)
Remove redundant WP_JSON_Pages::type_archive_link() function

(props @thenbrent, #29)
Removed unneeded executable bit on all files

(props @tierra, #31)
Don't include the featured_image property for post types that don't support thumbnails

(props @phh, #43)
Use wp_json_server_before_serve instead of plugins_loaded in the Extending documentation for plugins

(props @phh, #43)
Parse the avatar URL from the get_avatar() function in core, allowing custom avatar implementations

(props @rachelbaker, #47, #35)
Ensure that the author is set if passed

(props @kuchenundkakao, #44)
Clarify the usage of WP_JSON_CustomPostType in plugins

(props @rmccue, #45)
Ensure JSON disabled error messages are translated

(props @rmccue, #38)
Remove extra "Link: " from link headers

(props @jmusal, #56, #30)
Remove redundant get_avatar method in WP_JSON_Posts

(props @rachelbaker, #35)
Rename WP_JSON_Server::get_avatar() to WP_JSON_Server::get_avatar_url()

(props @rachelbaker, #35)

The response handler object is now passed into the endpoint objects via the constructor, allowing you to avoid excess global state where possible. It's recommended to use this where possible rather than the global object.

(props @rmccue, #2)
Fix undefined variables and indices (props @pippinsplugins, #5)
Correct call to deactivation hook (props @ericpedia, #9)
Check metadata access correctly rather than always hiding for users without the edit_post_meta capability (props @kokarn, #10)
Return all term metadata, rather than just the last one (props @afurculita, #13)
Access post metadata from cache where possible - Note, this is a backwards compatibility break, as the format of the metadata has changed. This may change again in the near future, so don't rely on it until 1.0. (props @afurculita, #14)
Add term_link to prepare_term (props @afurculita, #15)
Fix hardcoded /pages references in WP_JSON_CustomPostType (props @thenbrent, #26)
Sanitize headers for newlines (props @kokarn, #7)
Register rewrite rules during plugin activation (props @pippinsplugins, #17)

Huge documentation update - Guides on getting started and extending the API are now available for your perusal
Add generic CPT class - Plugins are now encouraged to extend WP_JSON_CustomPostType and get free hooking for common actions. This removes most of the boilerplate that you needed to write for new CPT-based routes and endpoints (#380)
Use defined filter priorities for endpoint registration - It's now easier to inject your own endpoints at a defined point
Update the schema - Now includes documentation on the Media entity, plus more (#264)
Add better taxonomy support - You can now query for taxonomies and terms directly. The routes here might seem strange (/posts/types/post/taxonomies/category for example), but the intention is to future-proof them as much as possible(#275)
Ensure the JSON URL is relative to the home URL (#375)
Check all date formats for If-Unmodified-Since (#378)
Register the correct URL for the JS library (#376)
Correct the usage of meta links (#379)
Add filters for post type and post status data (#380)
Separate parent post and parent comment relation (#330()

Add support for media - This has been a long time coming, and it's finally at a point where I'm happy to push it out. Good luck. (#272)
Separate the post-related endpoints - Post-related endpoints are now located in the WP_JSON_Posts class. When implementing custom post type support, it's recommended to subclass this.

The various types are now also only registered via hooks, rather than directly in the server class, which should make it easier to override them as well (#348)
Add page support - This is a good base if you're looking to create your own custom post type support (#271)
Switch from fields to context - Rather than passing in a list of fields that you want, you can now pass in a context (usually view or edit) (#328).
Always send headers via the server handler - Endpoints are now completely separate from the request, so the server class can now be used for non-HTTP/JSON handlers if needed (#293)
Use better error codes for disabled features (#338)
Send X-WP-Total and X-WP-TotalPages headers for information on post/pagination counts (#266)

0.4

Add Backbone-based models and collections - These are available to your code by declaring a dependency on wp-api (#270)
Check json_route before using it (#336)
Conditionally load classes (#337)
Add additional test helper plugin - Provides code coverage as needed to the API client tests. Currently unused. (#269)
Move json_url() and get_json_url() to plugin.php - This allows using both outside of the API itself (#343)
getPost(0) now returns an error rather than the latest post (#344)

View all changes

0.3

Add initial comment endpoints to get comments for a post, and get a single comment (#320)
Return a Post entity when updating a post, rather than wrapping it with useless text (#329)
Allow filtering the output as well as input. You can now use the json_dispatch_args filter for input as well as the json_serve_request filter for output to serve up alternative formats (e.g. MsgPack, XML (if you're insane))
Include a profile link in the index, to indicate the JSON Schema that the API conforms to. In the future, this will be versioned.

0.2

Allow all public query vars to be passed to WP Query - Some private query vars can also be passed in, and all can if the user has edit_posts permissions (#311)
Pagination can now be handled by using the page argument without messing with WP Query syntax (#266)
The index now generates links for non-variable routes (#268)
Editing a post now supports the If-Unmodified-Since header. Pass this in to avoid conflicting edits (#294)
Post types and post statuses now have endpoints to access their data (#268)

Disable media handling to avoid fatal error (#298)

0.1.1

No changes, process error

0.1

Enable the code to be used via the plugin architecture (now uses rewrite rules if running in this mode)
Design documents are now functionally complete for the current codebase (#264)
Add basic writing support (#265)
Filter fields by default - Unfiltered results are available via their corresponding *_raw key, which is only available to users with edit_posts (#290)
Use correct timezones for manual offsets (GMT+10, e.g.) (#279)
Allow permanently deleting posts (#292)

0.0.4

Hyperlinks now available in most constructs under the 'meta' key. At the moment, the only thing under this key is 'links', but more will come eventually. (Try browsing with a browser tool like JSONView; you should be able to view all content just by clicking the links.)
Accessing / now gives an index which briefly describes the API and gives links to more (also added the HIDDEN_ENDPOINT constant to hide from this).
Post collections now contain a summary of the post, with the full post available via the single post call. (prepare_post() has fields split into post and post-extended)
Post entities have dropped post_ prefixes, and custom_fields has changed to post_meta.
Now supports JSONP callback via the _jsonp argument. This can be disabled separately to the API itself, as it's only needed for cross-origin requests.
Internal: No longer extends the XMLRPC class. All relevant pieces have been copied over. Further work still needs to be done on this, but it's a start.

0.0.3:

Now accepts JSON bodies if an endpoint is marked with ACCEPT_JSON
