Thanks for the response, but I don't think this plugin does what I am attempting to do.
One way I've tried to do this with a Cornerstone Element was to insert Raw Data, but it doesn't appear to support PHP.
If I could do something like the following:
<?php echo get_post_meta($post->ID, 'key', true); ?>
Except in specific spots on a post, this is ultimately what I'm trying to achieve. The 'key' will return different data for every single post, so I don't think ACF Pro accomplishes this, as it appears to show the same content just in multiple locations on your website.
Is there any way to achieve what I described?
