Featured Images link to post parent

Question

I want to reuse featured images for new posts. So a single featured image from the media library is attached to more than one post. When i use post_parent ); ?> on the attachment page to go back to the post, the user will be redirected to the first post the image was attached.

How can i redirect the user to the actual post the user comes from?

Answer 1

You might use $_SERVER['HTTP_REFERER'] but take in mind that is not always sent so check for its existence and think about a fallback!
