Add custom code on a specific page

Hello,

Is there a way to have a specific piece of custom code showing only for the homepage?

Im trying to get a different og:image tag for each page.

I did find this on Google but although my menu id = 101 its not working

<?php
$app = JFactory::getApplication();
$itemid   = $app->input->getCmd('Itemid', '');
if ($itemid == 101) : ?>
[PUT YOUR CODE HERE]
<?php endif; ?>

Can anybody help

marcusknapman Hi. Please try using it like this:

<?php
$itemid  = JFactory::getApplication()->input->post->get('Itemid');
if ($itemid == 101) : ?>
[PUT YOUR CODE HERE]
<?php endif; ?>
