Foreach in template hook

[Cupara]

Is it possible to do a foreach when using a template hook in the 'message' template? Every time I try it gives me an error that the BbCode_TextWrapper is already in use and cannot be used again.

Go figure, anyway, not sure how else to go about it. I am using a Listener for Post and a Model.

Here is my listener:

class xShop_Listener_Post
{
/**
* If we are getting the post model, extend it with our custom class that holds a method
* for the images.
*
* @param string The name of the class to be created
* @param array A modifiable list of classes that wish to extend the class.
*/
public static function listen($class, array &$extend)
{
if ($class == 'XenForo_Model_Post')
{
$extend[] = 'xShop_Model_Post';
}
}

}

Here is my model:

/**
* Model for posts.
*
* @package xShop
*/
class xShop_Model_Post extends XFCP_xShop_Model_Post
{
    /**
    * Constants to allow joins to extra tables in certain queries
    *
    * @var integer Join xShop tables
    */
    const FETCH_XSHOP = 0x60;

    /**
    * Gets the specified posts - extended to include thread ban info
    *
    * @param array $postIds
    * @param array $fetchOptions Collection of options that relate to fetching
    *
    * @return array Format: [post id] => info
    */
    public function getPostsByIds(array $postIds, array $fetchOptions = array())
    {
        if (!empty($fetchOptions['join']))
        {
            $fetchOptions['join'] |= self::FETCH_XSHOP;
        }
        else
        {
            $fetchOptions['join'] = self::FETCH_XSHOP;
        }

        return parent::getPostsByIds($postIds, $fetchOptions);
    }

    /**
