在插入新用户时，我想在Wordpress中添加一个自定义的帖子类型（称为pullow）。这个wp_insert_user() 用于创建新用户。

我有以下代码：

function register_user_pupil($user_id) {

    //Count nr of occurences in user-table for submitted email-adress
    $email_form = $_POST[\'email\'];
    $sql = "SELECT * FROM $wpdb->users";
    $sql .= " WHERE user_email = \'%s\'";    
    $count_users_email = intval($wpdb->get_var($wpdb->prepare( $sql, $email)));

    //Check if email (from exists) already exists in the system (in users table)
    //If it doesn\'t, create new user into variable. If it does, store that user in variable
    //based on email-adress
    if ($count_users_email === 0) {
        $current_user = new WP_User($user_id);
    }
    else {
        $current_user = get_user_by( \'email\', $email_form );
    }

    //Create a new pupil custom post-type for this user
    $user_registration_post = array(
      \'post_title\'      => $current_user->display_name,
      \'post_type\'       => \'pupil\',
      \'post_status\'     => \'draft\',             //This registration cpt is not available for public
      \'post_author\'     => $current_user->ID
    );
    $postid_pupil = wp_insert_post( $user_registration_post );

    //postid should return something above 0 and not a WP_Error-object
    if (is_array($postid_pupil) || intval($postid_pupil) === 0) {                        
        throw new Exception(\'Kan inte skapa en elev-registrering\');
    }

    //Rest of updating is done by function postsubmit() (saving the pupil CPT)

}
//Hook for handling new users 
add_action( \'user_register\', \'register_user_pupil\', 10, 3 );

问题是调用此函数AFTER 用户已插入，我希望执行它BEFORE 插入实际用户。我还尝试使用register\\u post挂钩，但在插入用户之前，不会调用此代码。我也试着弄清楚我是否可以用钩子pre_{something}, 但是没有运气。

有人能帮我吗？非常感谢：-）

function register_user_pupil($user_id) {
  $current_user = new WP_User($user_id);

  $post_args = array(
    \'post_title\'      => $current_user->data->display_name,
    \'post_type\'       => \'pupil\',
    \'post_status\'     => \'draft\',             //This registration cpt is not available for public
    \'post_author\'     => $current_user->ID
  );
  $exists = new WP_Query($args);

  if (!$exists->have_posts()) {
    $postid_pupil = wp_insert_post( $post_args );
  }  

  //postid should return something above 0 and not a WP_Error-object
  if (is_array($postid_pupil) || intval($postid_pupil) === 0) {                        
      throw new Exception(\'Kan inte skapa en elev-registrering\');
  }

  //Rest of updating is done by function postsubmit() (saving the pupil CPT)

}
add_action( \'profile_update\', \'register_user_pupil\');
add_action( \'user_register\', \'register_user_pupil\');

add_action( \'user_register\', \'register_user_pupil\', 50, 1 );
