Reply To: Custom location rules for attachment modals

I’ve had the same problem myself. I was looking for a way to only show fields when the attachment was an image. Unfortunately I was never able to do so. What I did was I set my acf/location/rule_match/attachment filter to output information to a file. I tried outputting everything I could think of to this file to see if there was anything that would tell me the post id or any useful information so that I could show the images on the WP modals with no luck.

Anyway, if someone else would like to try this and see if they can come up with anything that I missed, this is the code I put into my filter, if outputs stuff into a txt file in the same folder as the file with the function in it.

  add_filter('acf/location/rule_match/attachment', array($this, 'match_attachment_image'), 20, 3);
  function match_attachment_image($match, $rule, $options) {
    
    global $post;
    
    $file = dirname(__FILE__).'/output.txt';
    if (($handle = fopen($file, 'a')) !== false) {
      ob_start();
      echo "\r\n",'$match = '; var_dump($match);
      echo "\r\n",'$rule = '; var_dump($rule);
      echo "\r\n",'$options = '; var_dump($options);
      echo "\r\n",'$post = '; var_dump($post);
      echo "\r\n".'$_POST = '; var_dump($_POST);
      echo "\r\n".'$_GET = '; var_dump($_GET);
      fwrite($handle, ob_get_clean());
      fclose($handle);
    }
    return $match;
  }
