#50089 new enhancement

Allow filtering of image uploads

I'd like to be able to filter the response of wp_ajax_upload_attachment to add copyright and duplicate checks to prevent the upload of the image if either fails.

To do this I require an apply_filters at the end of the function.

Suggested fix for ajax-actions.php function wp_ajax_upload_attachment:


echo wp_json_encode( array(
        'success' => true,
        'data'    => $attachment,
) );


$response = array(
    'success' => true,
    'data'    => $attachment,
$response = apply_filters( 'filter_ajax_upload_attachment_response', $response );

echo wp_json_encode( $response );

Hi there, welcome back to WordPress Trac! Thanks for the ticket.

Just noting there are some existing hooks called when uploading a new image:

But these are hooks and they can NOT be used to set the success to false in case the upload was cancelled by my custom code. (unless I die() in them, but this makes it really hard to debug code for other people, bc if someone hooked already & died, later hooked actions may actually never run)

Note: See TracTickets for help on using tickets.
