Castlegate IT WP Conditional Downloads

Castlegate IT WP Conditional Downloads can be used to restrict access to any files uploaded to the WordPress media gallery. By default, the plugin provides a simple "restrict access to this file" checkbox for each file, which restricts access to registered users. The checkbox is added with Advanced Custom Fields.

Custom restrictions

You can edit the file attachment restrictions via the cgit_condo_attachment_restricted filter:

add_filter('cgit_condo_attachment_restricted', function ($restricted, $attachment) {
    return $restricted;
}, 10, 2);

This function should return a boolean value that will be used to determine whether access to the file should be restricted. The attachment itself is provided as a WP_Post instance in the second function parameter.

You can also edit whether the current user is allowed to access the file or not via the cgit_condo_user_permitted:

add_filter('cgit_condo_user_permitted', function ($permitted, $attachment, $user) {
    return $permitted;
}, 10, 3);

This should return a boolean that will be used to determine whether the current user is permitted to download the file. The attachment and user are provided as WP_Post and WP_User instances respectively.

Custom messages

The title, message, and HTTP response code of the "access denied" page can be edited via the cgit_condo_forbidden_title, cgit_condo_forbidden_message, and cgit_condo_forbidden_code filters respectively.
