How to see if a Post in WordPress has an Excerpt

On the single post page for our posts, we wanted to display the excerpt only if one had been entered. Since the built-in WordPress function to get the excerpt for a post will automatically generate one for you, we couldn’t just put the function in our post loop like what was done below.


Doing this causes the intro of the post to show twice, once from the auto-generated excerpt and once in the post content. To fix this, we added a quick check to the post loop. Simply replacing the_excerpt function in the post loop with this little piece of code removed the double intro.
