Media Cleaner doesn’t detect usage of attachments on ACF options pages

    Basically the title says it all – I have a few ACF options pages where I also have some image fields. These images are detected as “not used” by Media Cleaner. I can of course make use of the filter wpmc_check_media and return true for these images, but still thought it would be worth informing you about the issue.

    Should you decide that you want to support this: You can get information about all registered options pages like this:

    add_action('init', function() {
    $options_pages = acf_get_options_pages();
    // do your magic with the information
}, PHP_INT_MAX); // run at the very end of the 'init' hook

    As a temporary workaround I developed this filter callback:

    /**
 * Tells Media Cleaner Pro if an image is in use on any ACF options page
 * @see https://meowapps.com/media-cleaner/faq/#media-library-method
 *
 * @param bool $is_used     What WPMC thinks about the attachment
 * @param int $id           The attachment ID
 */
function check_if_media_is_in_use_on_acf_options_pages(bool $is_used, int $id): bool
{
    $options_pages = acf_get_options_pages();
    if (empty($options_pages)) return $is_used;

    // This is what we will be looking for:
    $serialized_id = serialize((string) $id);

    // Look through all options pages
    foreach ($options_pages as $options_page) {
        // Get a serialized array of all fields, unformatted
        $serialized_fields = serialize(get_fields($options_page['post_id'], false) ?: []);
        // Check if the serialized $id can be found in the serialized fields
        if (str_contains($serialized_fields, $serialized_id)) return true;
    }

    return $is_used;
}
add_filter('wpmc_check_media', 'check_if_media_is_in_use_on_acf_options_pages', 10, 2);

    To support all possible scenarios (single image/file, gallery, repeaters, flexible content,…) I opted to just serialize all fields and check if the serialized version of the $id can be found there. Works smoothly!
