XF 2.0 Alert after a thread is created externally

[LPH]

I'm attempting to create a post externally then have an alert sent to the author's XenForo account.

An exception occurred: [InvalidArgumentException] Attempted to convert NULL to integer [content_id] in src/XF/Mvc/Entity/Entity.php on line 688

Here is the code:

/**
 * @param $post
 *
 * @return string
 * @throws \Exception
 */
public function insert( $post ) {

   $title = $this->getTitle( $post );
   $message = $this->getMessage( $post );

   // Get the forum using forum_id
   $forum_id = $this->getForumId( $post );

   $forum = \XF::em()->find( 'XF:Forum', $forum_id );

   /** @var \XF\Entity\User $author **/
   $author = \XF::app()->find('XF:User', $post->post_author);

   $thread = \XF::asVisitor($author, function() use ($forum, $title, $message, $post)
   {
      /** @var \XF\Service\Thread\Creator $creator */
      $creator = \XF::service('XF:Thread\Creator', $forum);
      $creator->setContent( $title, $message );
      $creator->setPrefix( $this->getForumId( $post ) );
      $creator->setTags( $this->getTags( $post ) );
      $creator->setIsAutomated();

      if (!$creator->validate())
      {
         return null;
      }

      $creator->save();
      $this->postMeta( $creator, $post );

   });

   $user = \XF::visitor();

   /** @var \XF\Repository\UserAlert $alertRepo */
   $alertRepo = \XF::app()->repository('XF:UserAlert');
   $alert = $alertRepo->alertFromUser($user, $author, 'post', $thread->first_post_id, 'mention');

   return $alert;
}

OK. Figured out which in the NULL. The $thread is not being pulled. As soon as I pull the $thread_id from the WP post meta table then the alert fires without the error.

However, I'm using 'mention' and wonder if there is a better alert.

Looks like 'insert' is more appropriate.

I feel like I should warn you that using $this inside anonymous functions / closures can be dodgy depending on the PHP versions you are targetting.

Support for it was introduced in PHP 5.4.

Thank you. I’m very new to closures. I’m not sure of any other way to calling the postMeta method, and passing the $creator and $post.

You can always just require 5.4 as the minimum version, I'm not sure if XF2 even supports 5.3. I know it won't in 2.1.

I just wanted to let you know, you shouldn't have to change your code

5.4 is the minimum for my plugin; however, I’m not sure if there is a better way.
