I AM NO LONGER SUPPORTING THIS PROJECT

Medium Editor needs your help!. This plugin depends Medium Editor which is the JavaScript package that powers this ACF Add On. I do not maintain this package. This plugin is simply an implementation of it for ACF. Medium Editor is looking for contributors. Without people to help maintain and improve it Medium Editor could fade away and if that happens this plugin will no longer be possible.

Please do not install this plugin from here. The plugin here has a different slug than the one on wordpress.org. When this plugin in updated it will be updated from wordpress and not from this repo. This will cause the plugin to be deactivated when it is updated.

Advanced Custom Fields: Medium Editor Field

Suported ACF Versions

• ACF 5

Ever needed to give a client a way to edit the appearence of text without wanting to give them a full blown WYSIWYG editor? Need something less than a WYSYWIG but more than a text or textarea field that you can configure the way you need it to work with the features you need it to have?

== Installation ==

1. Copy the acf-medium-editor-field folder into your wp-content/plugins folder
2. Activate the Medium Editor Field plugin via the plugins admin page
3. Create a new field via ACF and select the Medium Editor Field type
4. Please refer to the description for more info regarding the field type settings

##Configurable Medium Editor WYSIWYG Field for ACF

This add on for ACF5 adds MediumEditor as an ACF field. Each field instance is configurable, and each field instance has its own settings. Many of the options available in MediumEditor are supported, including the creation of custom buttons using MediumButton. It is also possible using either a configuration setting or a filter to alter the MediumEditor Theme. Some of the available options are covered below. For more information on MediumEditor and MediumButton, see the description of these libaries at the links above.

Please note that this is only available for the ACF5 verion. It will not work in ACF4. As you'll see looking at the field settings, I've added a repeater field (and a nested repeater to the settings for this field type. It may work with ACF4 and with the repeater add on, but the JavaScript would need to be rewritten for that and if you're using ACF4 and the repeater add on then you may as will upgrade to ACF5.

I have created this custom field with specific features of MediumEditor that I need for a project I'm currently working on. The most important feature is the inclusion of MediumButton so that I can create custom buttons that will allow me to complete the admin to meet the client's needs for modifying things like text color of specific portions of text. I'm not apposed to adding more options and features of MediumEditor, drop me a note in issues for this repo and I'll consider them.

There are actually several ACF addons that use MediumEditor, but I needed something that I could congifure differently for each instance and I especially needed to be able to easily add custom buttons and the easiest way to do that was with MediumButton. I couldn't find one and honestly, editing any of the existing ones to allow what I needed would have mean completely rebuilding them anyway. So this is my take on it. Hopefully others find it usefull.

Field Settings

See Setting Descriptions Below Screenshot

The following is an explanation of the fields, not including the ones that should be self explanatory.

Buttons: These are the buttons that are included in MediumEditor. Select the buttons you want to include in each editor instance.

Custom Buttons: This is the main reason that I created this plugin. This field supports adding custom buttons using MediumButton. Please note that if any of the main fields (Name, Label, HTML Tag) are empty that the entire button will be ignored.

Name: This is then name of the button and will be used when instaniating the MediumButton Object. The button name must be unique and cannot be one of the buttons already included in MediumEditor, a button of the same name as on of the standard button in Medium Editor will not override that button if it is also included. I do not know what the effects of custom characters in the name will be. Please report any bugs and I will look into adding something to clean up characters or find some other work-around for any that cause errors.

Label: This is the label that will appear in the button bar. This field allows HTML. Please make sure it is valid html (I do not validate the html you enter). Invalid markup will probably break the button bar or the entire admin. MediumButton also supports using icons for buttons. If you want to use icons in your buttons then it is your responsibility to make sure the icon font set is available for use in the admin of your site.

HTML Tag: Enter the html tag that will be inserted by this button. Only non-empty html tags are allowed. Most valid HTML tags are supported. If an invalid HTML tag is entered then the button will be ignored.

I'm not sure at this time what effect some of the tags will have in the editor. I haven't tried them all if you run into issues let me know and I'll need to make a decision on wheter to try to fix it or remove the tag(s) from the allowed list.

The currently supported tags are: abbr, acronym, address, article, asside, b, bdi, bdo, blockquote, button, caption, cite, code, del, details, dfn, div, em, footer, h1, h2, h3, h4, h5, h6, header, i, ins, main, mark, meta, p, pre, q, s, samp, section, small, span, strong, sub, sup, summary, time, u, var, wbr

Attributes: Add attributes to the html tag. Attibute names must be valid (they must begin with a letter and contain only letter, numbers, underscores and dashes. Attribute values must not contain double quotes (") any attributes that do not conform to these rules will be ignored. Please note that beyond this, attribute names and values are not validated. I do not know what effect invalid entries will have on your admin. Like other values, if you find something that causes an issue, open one and I'll see what needs to be done.

Other MediumEditor Options: This is a selection of other Core Options available for MediumEditor with the exception of allowBreakInSingleLineInput (see below). Please see the MediumEditor documentation for information on each of the other options. Selecting an option will set that option's value to true.

allowBreakInSingleLineInput: This is an option added specifically for use with WP. If you set disableReturn on then the medium editor acts like a single link input. Setting allowBreakInSingleLineInput allows editors to manually type in <br> tags into these single line fields.

MediumEditor Themes

MediumEditor fields will use the default theme unless you change it. You can alter the theme used for all MediumEditor fields, this is not something that you can apply only some fields. You can change the theme on your site in one of two ways:

1. wp-config.php Add the following code to your wp-cofig.php file

define('MEDIUM_EDITOR_THEME', 'beagle');

2. filter Add the following code to your functions.php file or wherever you would add such a filter

add_filter('medium-editor-theme', 'my_medium_editor_theme_function');
function my_medium_editor_theme_function($theme) {
  $theme = 'beagle';
  return $theme;
}

Theme names in the above code is one of the following themes currently supported by MediumEditor: beagle, bootstrap, default, flat, mani, roman, tim

For more information see MediumEditor and MediumButton

Custom Editor Styles

The styles used in the medium editor for elementa is inherited from WP. If you want to override these styles create a file named "medium-editor-syle.css" in your theme folder. If this file exists is will be automatcially enqueued on all pages where ACF fields appear.

Filters

Add Custom Buttons in Code

This filter is applied to the custom buttons before they are validated as having all the correct requirements that are given when creating a custom button in the field settings for a Medium Editor Field.

Hooks

1. acf/medium-editor-field/custom-buttons - filter for every field
2. acf/medium-editor-field/custom-buttons/name={$field_name} - filter for specific field based on it's name
3. acf/medium-editor-field/custom-buttons/key={$field_key} - filter for specific field based on it's key

Parameters

1. $buttons - an array of button options
2. $field - an array containing all the fields settings for the field being loaded

// functions.php

function my_custom_buttons($buttons, $field) {
  $buttons[] = array(
    'name' => 'red',
    'tag' => 'span',
    'label' => '<b title="Title for button" style="color: #F00;"><i class="dashicons dashicons-NAME"></i></b>',
    'attributes'  => array(
      array(
        'name' => 'style',
        'value' => 'color: #F00;'
      ),
      array(
        'name' => 'class',
        'value' => 'myClass'
      )
    )
  );
  return $buttons;
}
add_filter('acf/medium-editor-field/custom-buttons', 'my_custom_buttons', 10, 2);

For all dashicons available in WordPress take a look at the Dashicons List and get the correct name for the dashicons-NAME.

If you use your own icon font (e.g. Font-Awesome) the icon font set must be installed and included in the admin pages of your site.

Filter Buttons

This filter is applied to the list of buttons that will be shown. This list will contain the "name" of each standard button as well as the "name" of each custom button that has been set up for the field. Please note that only valid button names can be used here. See medium editor's list of available buttons.

Hooks

1. acf/medium-editor-field/buttons - filter for every field
2. acf/medium-editor-field/buttons/name={$field_name} - filter for specific field based on it's name
3. acf/medium-editor-field/buttons/key={$field_key} - filter for specific field based on it's key

Parameters

1. $buttons - an array of button options
2. $field - an array containing all the fields settings for the field being loaded

// functions.php

function my_custom_buttons($buttons, $field) {
  // add underline button to all medium editor fields
  // set both the index and the value of the array element
  if (!isset($buttons['underline'])) {
    $buttons['underline'] = 'underline';
  }

add_filter('remove_hube2_nag', '__return_true');
