Config

You can customise the CMS tab that the gallery appears on, as well as the title of the gallery displayed in the CMS:


HomePage:
extensions: - PurpleSpider\BasicGalleries\PhotoGalleryExtension
gallery-title: Image Gallery
gallery-cms-tab: Main

Automatically Delete Image Files

To automatically delete image files when an image is deleted from a gallery:

---
Name: custom-basic-gallery-extension
After: basic-gallery-extension
---
PurpleSpider\BasicGalleryExtension\PhotoGalleryImage:
    ondelete_delete_image_files: true

This uses Delete Asset If Unused Extension to detect if the image is being used elsewhere on the site, and will only delete it if it isn't. There are caveats though, so check this module's readme, i.e. you might not want to use this on sites that have been upgraded from Silverstripe 3.

Version Details

  • 0.* = SilverStripe 3
  • 1.* = Silverstripe 4
  • 2.* = Silverstripe 4 (Uses newer version of PhotoGalleryExtension with a polymorphic relation, so upgrading from 1 to 2 will break existing galleries.)
  • 3.* = Silverstripe 5

Upgrade Notes

To v1 or higher (extension moved to seperate module)

  • Change any references to the extension, e.g. if applied to the Homepage type, from PurpleSpider\BasicGalleries\PhotoGalleryExtension to PurpleSpider\BasicGalleryExtension\PhotoGalleryExtension
  • PurpleSpider\BasicGalleries\PhotoGalleryImage is now PurpleSpider\BasicGalleryExtension\PhotoGalleryImage (in case you applied your own extension to it)
  • Run dev/build to update table names automatically (via legacy.yml)

to v2 or higher (individual page and elemental relations changed to a single polymorphic relation)

  • Complete "To v1" upgrade instructions, inc dev/build
  • Run /dev/tasks/upgrade-basic-galleries script to update database for existing galleries.

to v3 (Silverstripe 5)

  • Nothing extra required, just change version to ^3.
