Using ACF Custom Fields in MesoColum

First off, this is a wonderful theme, love it to death.

The only thing left on my checklist before I make my blog redesign live is to get a single ACF custom field to show up on every post.

I read up on creating a hook into bp_after_post_content (this is my first foray into the wacky world of php) but I couldn’t see it being called anywhere.

I even tried this directly in single.php but got nowhere (yes, I know I should be using a child form but right now I’m just trying to even get the basics to work!)

<?php

add_action('bp_after_post_content', 'show_acf', 10);

function show_acf()
{
?>
<H1>Hello</H1>
<?php
}
?>
