 * Hello,
 * I’m making a basic php basket and i’m trying to retrieve different informations.
   So far so good I got the title, the content, the permalink everything is working
   at intended. But i’d like to save the_post_thumbnail in an input hidden like 
   this :
 * <input type=’hidden’ name=’thumbnail_image’ value=”<?php the_post_thumbnail();?
   >” />
 * The problem is that it returns me a number. But I’ve basically never done this
   in the past even with a basic image. So how should I proceed save this picture
   in my array?
 * Thanks for your help.

 * `the_post_thumbnail()` outputs the HTML to display the thumbnail, it does not
   return anything meaningful. What is it you are actually trying to get, the thumbnail
   URL? That is returned by `wp_get_attachment_thumb_url()`, but if the call is 
   not in the “Loop”, you must provide the post ID as a parameter.
