Get custom fields

Hi!

Well, I did some experiments, and made a function that works in most cases. Put this into the functions.php file in your active theme directory:

add_filter('asl_results', 'get_all_the_meta', 10, 1);

function get_all_the_meta( $results ) {
  global $post;
  
  foreach ($results as $k => &$r) { 
    if ($r->content_type != 'pagepost') continue;
    $post = get_post($r->id);
    setup_postdata($post);
    if ( $keys = get_post_custom_keys() ) {
      $r->content .= "<ul class='post-meta'>\n";
      foreach ( (array) $keys as $key ) {
        $keyt = trim($key);
        if ( is_protected_meta( $keyt, 'post' ) )
               continue;
        $values = array_map('trim', get_post_custom_values($key));
        $value = implode($values,', ');
        $r->content .= apply_filters( 'the_meta_key', "<li><span class='post-meta-key'>$key:</span> $value</li>\n", $key, $value );
      }
      $r->content .= "</ul>\n";
    }
  }
  
  wp_reset_postdata();
  
  return $results;
}

I hope it helps!

Yes, thank you!
