Dynamically set image field to readonly/disabled?

  • I’m trying to use the acf/load_field callback to dynamically set some fields to readonly and/or disabled. This works fine for most fields, but doesn’t appear to work for image fields. Is it possible to dynamically block image fields from being changed in the backend?

        add_filter('acf/load_field/name=test_image', function($field) {
            $field['readonly'] = 1;
            $field['disabled'] = 1;
            return $field;
  • Not by using that filter. Those settings only work for simple fields. I do not know the details but this is probably something that you’d need to do using JavaScript. To be honest I’m not even sure if that’s possible.
