How to Retrieve Only the SRC of a Post Thumbnail in WordPress

Are you looking for a way to retrieve only the src of a post thumbnail? While there’s probably a plugin for this, we have created a quick code snippet that you can use to retrieve only the src of a post thumbnail in WordPress.

Instructions:

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

function example_post_thumbnail_src($post_id, $echo = true) {
    $attachment = wp_get_attachment_image_src(get_post_thumbnail_id($post_id), $size);
    if(!$echo){
      return $attachment['0'];
    }else{
      echo $attachment['0'];
    }
}

Add the following code within the WordPress loop of your theme’s single.php file.

<img src="<php example_post_thumbnail_src(get_the_ID()); ?>" .../>
