php - set og tags for homepage only

Get the solution ↓↓↓

Solution:

If you want to edit the template directly, here is a conditional check you can do to see if the homepage is being displayed:

(Assuming you are using Joomla 2.5 or 3.x. See this link for more info & other versions)

<?php
  $app = JFactory::getApplication();
  $menu = $app->getMenu();
  if ($menu->getActive() == $menu->getDefault()) {
      echo '<meta property="og:image" content="http://www.example.com/facebook.jpg" /> ';
  }
?>
Copy code

Ideally, you would create a plugin to add the meta tag to your HTML HEAD so updates to your template do not overwrite your changes.
