I'm using the Achievements module to award the badges to users on certain actions.

In the following example user will get badges after posting 5 and 10 comments.

function MYMODULE_comment_insert($comment) {
  $current_count = achievements_storage_get('comment-count', $comment->uid) + 1;
  achievements_storage_set('comment-count', $current_count, $comment->uid);

  foreach (array(5,10) as $count) {
    if ($current_count == $count) {
      achievements_unlocked('comment-count-' . $count, $comment->uid);
    }
  }
}

The above code is working, user is able to achieve badge after posting 5 comments but since the comment form is being submitted through AJAX, the rewarded achievements notification popup is not being shown until page refresh.

So how can I show achievement notification popup for Ajax callbacks? Any suggestions?

  • Do you use drupal.org/project/ajax_comments or your own code for ajaxify comments? Mar 16 '16 at 11:17
  • @MariaKvitova No I'm using Flag and Drupal Wall modules which uses Ajax. Thanks Mar 16 '16 at 12:12
  • Could you tell what version of Drupal wall do you use? I tried 7.x-2.7 it doesn't seem to work :( You can find that message appears from hook_page_alter cgit.drupalcode.org/achievements/tree/… So you can use it in your ajax-callback and return message as ajax-command. Unfortunately I can't give you more details, because I couldn't force Drupal Wall to work. Mar 17 '16 at 10:49

Here is another try at this (various assumptions follow):

  • The whole thing should run through the Wall module's code, since this is the base for any other interaction happening.
  • By means of the Form API and AJAX callbacks, there is a possible entry point. This is to wrap the submit callback for the _drupal_wall_comment_post_form into another callback that will make sure the Achievements' related elements are updated.
  • The steps in this process would be:

    1. Use hook_form_alter to modify _drupal_wall_comment_post_form
    2. Modify _drupal_wall_comment_post_form by hijacking the ajax callback for the wall comment submissions: $form['drupal_wall_submit']['#ajax']['callback'] =>_your_custom_wall_ajax_callback

    3. Wrap the original callback in your ajax callback and extend it to trigger the Achievements popup functionality using the Ajax framework commands family:

      function _your_custom_wall_ajax_callback($form, $form_state) {  
        $wall_wrapper = $form['drupal_wall_submit']['#ajax']['wrapper'];
        $wall_content = _drupal_wall_comment_ajax_form_post($form, $form_state);
        $commands = array();
        $commands[] = ajax_command_replace($wall_wrapper, $wall_content);
      
        // This is where you can write ajax commands to trigger Achievements functionality
        $commands[] = ajax_command_*();
      
        return array('#type' => 'ajax', '#commands' => $commands);
      }
      

Hope this brings you a step further!

  • You are welcome! It would be great to update your question with things you tried and didn't work, what would you say? Cheers Mar 21 '16 at 21:53

You could try using Rules to add a rule for when a user post a comment and then do your thing

After creating the rule you can set conditions and actions, so you can check for the comment count and then act accordingly
