Simple Post Thumbnails + Gravity Form

Wondering the same thing ... anybody?

Hello

Here is a simple code that makes a post thumbnail (featured image in Wordpress 3.2) from first photo attached to the post.

add_action("gform_post_submission", "my_post_submission", 10, 2);

function my_post_submission($entry, $form){

  # Here you should check if $form is the right form, otherwise it will work for all forms.

  $post = get_post($entry["post_id"]);
  $arrImages =& get_children('post_type=attachment&post_mime_type=image&post_parent=' . $entry["post_id"] );
  if(is_array($arrImages)) {
    foreach ($arrImages as $attachment_id => $Image) {
      set_post_thumbnail( $post, $attachment_id );
      break;
    }
  }

}
