Media Sites HTML Callback of a TEMPLATE doesn't count as post content?

[Jaxel]

I have a BB Code Media Site that has an HTML Callback for the embed code. I am trying to make a post on my site that has ONLY a single bb code for this media site. I'm embedding a video, and the video is the only contents of the post.

If my HTML callback is as follows, it works fine:

    public static function embed($key, array $site)
    {
        return 'this is a test';
    }

However, if my HTML callback is as follows, I always get the error "Please enter a valid message.":

    public static function embed($key, array $site)
    {
        return new XenForo_Template_Public('My_Template', array('key' => $key));
    }

For some reason, the contents of the template are never considered in the length of the message.

Second code returns template object, not HTML code. You should call render() method and return code

public static function embed($key, array $site)
   {
       $template = new XenForo_Template_Public('My_Template', array('key' => $key));
       return $template->render();
   }
