How to Display Featured / Post Thumbnail Image Caption

Snippets by IsItWP

Are you looking for a way to display featured image caption in WordPress? While there’s probably a plugin for this, we have created a quick code snippet that you can use to display featured / post thumbnail image caption in WordPress.


All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:

function the_post_thumbnail_caption() {
  global $post;

  $thumbnail_id    = get_post_thumbnail_id($post->ID);
  $thumbnail_image = get_posts(array('p' => $thumbnail_id, 'post_type' => 'attachment'));

  if ($thumbnail_image && isset($thumbnail_image[0])) {
    echo '<span>'.$thumbnail_image[0]->post_excerpt.'</span>';

Add this code within the loop of the desired template file, single.php or, index.php to display featured image caption.

  1. thanks a lot, this works like a charm! Also works with a shortcode: just replace “echo” in the function with “return” and place a shortcode somewhere on your page.

  2. Hmmm. This is beaking my wp 5.2.2 website, with latest avada theme :-/

  3. Do you have a way to do this through multiple posts? We have solved the issue of showing the caption for a featured image. But, when we use that same image in a different post, all hell breaks loose.

    1. The idea would be to add this to your loop, unless I’m not following what you mean can you provide more details?
