Overview

Documentation of the process of refreshing cached front-facing content after editing gallery images in the Albums CMS.

Use cases

  • Add a new image to the gallery
  • Edit an existing image in the gallery
  • Delete an existing image in the gallery
  • Click "update cache" button for the gallery
  • Update the Album's cache

Process

Adding a new image to the gallery.

  • Click "add image" button.
    • JavaScript handler invokes the shared AJAX script, which returns the markup for the form as JSON.
    • Modal dialog opened with littled formDialog.js library.
  • Form filled out and submitted.
    • Shared AJAX handler saves image edits.
      /_ajax/images/edit_image.php
      • EditImagePage::commit_edit()
        (EditImagePage instanceof ajax_page_class)
        • cache_class::refresh_content_after_edit()
          • $content instanceof image_link_class → cache_class::refresh_content_after_image_edit()
      • GalleryUploadClass::save() → image_link_class::save() → image_link_class::upload()
        GalleryUploadClass → image_upload_class → image_link_class
        None of these classes have an update_cache() routine.
