   Test for presence of excerpt in a post.

   
   // Get $post if you're inside a function.
   global $post;
   
   if ( has_excerpt( $post->ID ) ) {
   	// This post has excerpt.
   } else {
   	// This post has no excerpt.
   }
   

When you need to hide the auto displayed excerpt and only display your post’s excerpts.

if ( ! has_excerpt() ) {
	echo '';
} else { 
	the_excerpt();
}

Replace auto excerpt with text or code.

<?php if ( ! has_excerpt() ) : ?>
	<!-- your text or code -->
<?php endif; ?>
