I am creating a post with wp_insert_post/wp_update_post. The post should have a featured image. But to set a featured image I need the postID. The problem is I do not have any postID. What I am doing is. I create a "profile page" for every user. Therefore the user just updates his data in the backend. The post is created automatically out of the data.

I tied things like:

set_post_thumbnail( wp_insert_post($post), $thumbnail_id );

But is does not work. Surprisingly set_post_thumbnail( wp_update_post($post), $thumbnail_id ); works. But in case I want to create a pot the first time, I need wp_insert_post.

I can provide the full code on request. Any ideas?

Thanks and regards Nico

  • wp_insert_post and wp_update_post return the post id when you use it, so you can use the id for stuff. – Wyck Mar 13 '14 at 23:27

As far as I know you can't add the thumbnail in the first array you send to create the post, you'll need to grab the post ID after the wp_insert_post, then run update_post_meta after the first part of the function.

If you post your function here we might be able to help a little further.

  • But how is it done from wordpress itself? If I create a post in the Admin area I can set a featured image while creating the post. Perhaps I could just copy and modify this action..? – kn1g Mar 14 '14 at 10:50
  • In WordPress, an id is established the second you click add new post. If you post your function here we can help. – Oturia Mar 15 '14 at 3:53
