注册时尝试在用户身上分配Wordpress帖子

Question

I'm currently working on a counselling website. My current issue I am having is getting WordPress to assign a wordpress post to a user when they register.

1) user clicks on link, this then takes them to the wordpress register page(standard wordpress register).

link build up "wp-login.php?action=register&post=4150"

2) once they're register I look on the post itself, and the author is still admin.

My code:

function on_user_register( $user_id ) {
    $id = $_GET['post'];
    $post = get_post($id);
    if($id){
      $update_creator = array(
                  'ID'          => $id, //created post ID
                  'post_author' => $user_id
              );

      wp_update_post( $update_creator );
  }
}

add_action( 'user_register', 'on_user_register', 10, 1 );

Answer 1

My immediate guess is that the $_GET variable is getting removed when the user submits the page because it is submitting the form using POST . You'll need to either modify the registration form to submit your variable to the form, or find another mechanism of bringing the information over (sessions? cookies? etc)
