Do you want to display specific content if post has_tag or specific tag? While there’s probably a plugin for this, we have created a quick code snippet that you can use to display post content if the post has tags or specific tag in WordPress.
Instructions:
All you have to do is add this code to your theme’s single.php file in the loop:
<?php
if(has_tag()){
echo 'this post has tags';
}else {
echo 'no tags sorry';
}
?>
Note: If this is your first time adding code snippets in WordPress, then please refer to our guide on how to properly copy / paste code snippets in WordPress, so you don’t accidentally break your site.

This works fine in articles and pages, but when I call up the search or the archive, for example, it is always based on the first article in the list. I don’t know how to prevent this. Example: I want to display something if an article or a page has the tag ID 123. This works in articles or pages. But if I e.g. list several article previews in search or archive, the code always orients itself at the FIRST article of this list.
