I have a simple code where I am attaching existing in the library image to a post:

function attachToPost($attachmentId, $postId){
    return wp_update_post(array(
        'ID' => (int)$attachmentId,
        'post_parent' => (int)$postId
    ));
}

The problem is that I can't attach it to a second post. I read in the internet that this is the way that WordPress works, but is there some kind of solution ?

I don't prefer plugins.

It is not possible to assign multiple parents to the attachment. However, there is an alternative solution. You can use update_post_meta. to store the attachment id to the post and similarly, you can use function get_post_meta. for getting the attachment id.

    Can you provide an example on how to do this?

What I did was to use set_post_thumbnail( $postId, $attachmentId );. With it, I can have one image attached to many posts.

    set_post_thumbnail() is clearly for Sets the post thumbnail (featured image) for the given post.

  • Yes, but in my case it doesn't matter, I am using the REST API and what and how I set there as a response is what and how the client uses, which is a React app.
