Additional Button Easysocial + jreviews

Hi guys,

I would like to add new button to the listing page of Jreviews component. Thats why i wrote a message to jreviews support to ask is that even possible... thats what i get back :

" Hi

You can find the solution here :


Read from the beginning of the article so you create the necessary filter file with the opening <?php tag. "

There is example for easysocial to add message button :

Examples
Add EasySocial Message Button

function add_easysocial_message_button($buttons, $params)

{

	if ( !defined('ES_MESSAGE_FILTER') )

	{

	   require_once(JPATH_ADMINISTRATOR . '/components/com_easysocial/includes/foundry.php');

 

	   ES::initialize();

 

	   ES::language()->loadSite();

 

	   define('ES_MESSAGE_FILTER', 1);

	}

 

	$listing = $params['listing'];

 

	$easysocial = '

	   <button type="button" class="jrButton jrSmall"

		data-es-conversations-compose=""

		data-id="'.$listing['User']['user_id'].'"

		data-es-provide="tooltip" 

		data-original-title="Contact This Member"

	   >

		<span class="jrIconMessage"></span> Contact This Member

	   </button>

	';

 

	$buttons[] = $easysocial;

 

	return $buttons;

}

 

Clickfwd\Hook\Filter::add('listing_detail_action_buttons', 'add_easysocial_message_button', 10);
