    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.
    }
    
  2. 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; ?>
