@alimir I very much appreciate your help but unfortunately my php skills are not as good as they should be.
My theme single.php file looks like this:
<?php get_header(); ?>
<div class="mh-wrapper clearfix">
<div class="mh-main clearfix">
<div id="main-content" class="mh-content" role="main" itemprop="mainContentOfPage"><?php
while (have_posts()) : the_post();
mh_before_post_content();
get_template_part('content', 'single');
mh_after_post_content();
comments_template();
endwhile; ?>
</div>
<?php get_sidebar(); ?>
</div>
<?php mh_magazine_second_sidebar(); ?>
</div>
<?php get_footer(); ?>
Where should I place the code? Please keep in mind I ONLY want to display the button in posts that are in the REVIEW CATEGORY, no other posts.
Also, if I want to add this to the child theme so it isn’t removed when you update the plugin, how would I go about doing so? I supposed I need to add the code to the functions.php in my child theme folder?
Sorry for the trouble, your plugin is really improving my site and means a lot.
