How to add link to the comment posting on a wall

I am not using comments module.

I am trying to customize setFacebookMessage () function in facebook.php .

function setFacebookMessage($message)
{
$facebookUpdateStatusMessage = $this->configModel->getSetting('facebook_update_status_msg');

if ($facebookUpdateStatusMessage && $message)
{
try
{
//$userId = self::getUserId(FALSE);
//$response = $this->api('/'.$userId.'/feed', array('message' => $message));
$response = $this->api('/me/feed', array('message' => $message));
#$fbClient->users_setStatus($message);
}
catch (JFBCFacebookApiException $e)
{
/*
Fatal error: Uncaught exception 'FacebookRestClientException' with message
'Updating status requires the extended permission status_update' in
.../com_jfbconnect/assets/facebook-api/facebookapi_php5_restlib.php:3007
*/
}
}
}


Here we are using $response = $this->api('/me/feed', array('message' => $message)); to pass the comments to facebook wall.

I am using like $response = $this->api('/me/feed', array('message' => $message , 'href' => $url ));
But its not working.
Suggest me to pass the url in this array.
