Adding text to the footer of each post based on tags or categories
I would suggest a filter on the_content much like: function conditional_footer_wpse_165930() { if (is_single()) { if (has_category(‘cat’)) { return ‘This is the cat footer’; } } } add_filter(‘the_content’,’conditional_footer_wpse_165930′,PHP_INT_MAX); I am not sure about all of the details you require. You may need to tweak that code.
