Are you looking for a way to return the post excerpt? While there’s probably a plugin for this, we have created a quick code snippet that you can use to get post excerpt in WordPress.
All you have to do is add this code to your theme’s post.php file in the loop or in a site-specific plugin:
<?php the_excerpt(); ?>
Note: If this is your first time adding code snippets in WordPress, then please refer to our guide on how to properly add code snippets in WordPress, so you don’t accidentally break your site.
