Link custom post type to users membership

I'm building a medical lab site, I'd like to link a custom post type - results to users. How can I link results CPTs to a user?

The idea is to be able to associate multiple test results to a single user/member. Currently using woocommerce membership to power the membership.

Please, any idea(s) or just point me in the right direction would be helpful. Thank you in advance!

• Use a custom field (meta key/value) that holds the user ID. Each Results post will have a user ID and one user ID can be applied to many results posts. wordpress.org/support/article/custom-fields – jdm2112 Commented Jul 29, 2021 at 13:08
• Aside: I'm not sure what the UK's healthcare privacy law is like, but in the USA, I would be very careful if not outright skeptical about any project wherein patients' medical data is stored on a WordPress site, as HIPAA law places a huge responsibility on fully securing such sites to very stringent standards with violation fees large enough to tank a small medical company (capped at $1.8 million/year). Even the lowest level violations can result in prison time. All of that terrifies me enough that I would never consider any variety of patient portal with WordPress as a live CMS. – bosco Commented Aug 1, 2021 at 20:45

If I can understand what you are looking for, you can create a simple function, that will fire when a new of the CPT is created and update a post_meta eg: "user_controler" for that.

Later, you will need to filter, the posts on the post.php, to show posts only related to the current user.

add_action("save_post", function ($post_ID, $post){
    $post = get_post($post_ID);
    $user = get_curent_user();

    if($post->post_type === "my_cpt" && !get_post_meta($post_ID, "my_meta_key")){
        update_post_meta($post_ID, "my_meta_key", $user->key);
    }
    //$user->key matches what you want to kip as link.
});

To filter the posts on the post.php page you can:

add_filter( 'posts_results', 'my_posts_results_filter' );
    
function my_posts_results_filter( $posts ) {
    global $my_global_condition;
    $user = get_curent_user();
    $screen = get_current_sreen();

    $filtered_posts = array();
        
    foreach ( $posts as $post ) {
        if (
        $post->post_type === "my_cpt" && 
        $screen->ID === $my_cpt && 
        get_post_meta($post_ID, "my_meta_key")=== $user->key
        ) {
                // It's allow :).
                $filtered_posts[] = $post;
        }
    }
    return $filtered_posts;
}

You can also use post_where filter.

You can also filter post simple base on the author property.
