Reply To: Header.php edits are not showing up in page source, by viosllc

I was told to put this code above </head> so that my video schema in my “custom fields” would be recognized by Google. This is the code that I is missing in the page source.

<?php
$schemamarkup = get_post_meta(get_the_ID(), ‘schemamarkup’, true);
if(!empty($schemamarkup)) {
echo $schemamarkup;
}
