注册后更新用户元

Question

在wordpress中，用户注册后，我正在使用下面的功能创建两种不同自定义帖子类型的两个页面，然后需要在他们的用户数据中存储一个自定义元值，以帮助以后进行重定向。 我发现，如果我在注册过程中（在注册表格上）指定了自定义元值，以后可以使用以下方法检索这些值：

global $current_user;
    get_currentuserinfo();
    $theirRedirectKey = $current_user->rpr_redirect_key;

但是，在以下functions.php代码段中，我无法保存元值以供以后检索。

function after_registration($user_id){
    // Get the Newly Created User ID
    $the_user = get_userdata($user_id);

    // Get the Newly Created User Name
    $new_user_name = $the_user->user_login;

    // Create a unique Tour Code Prefix from User ID
    $tourPrefix = $the_user->ID;

    // Check for Tour Code Key if entered into registration form
    $enteredKey = $the_user->rpr_redirect_key;

    if($enteredKey == ''){
        //Create the first Tour Builder Page
        $tourBuilder = array();
        $tourBuilder['post_title'] = $new_user_name . '| Custom Educational Tour';
        // Next line may not be important after hubpages are set up.
        $tourBuilder['post_name'] = 'builder-' . $tourPrefix;
        $tourBuilder['post_type'] = 'builder';
        $tourBuilder['post_content'] = 'This is the content!';
        $tourBuilder['post_author'] = $user_id;
        $tourBuilder['post_status'] = 'publish';
        $tour_id = wp_insert_post( $tourBuilder );

        // Build hubpage
        $hubpage = array();
        $hubpage['post_title'] = $new_user_name . '\'s Hubpage';
        // URL must be unique
        $hubpage['post_name'] = $new_user_name;
        $hubpage['post_type'] = 'hubpages';
        $hubpage['post_author'] = $user_id;
        $hubpage['post_status'] = 'publish';
        $hub_id = wp_insert_post( $hubpage );

        //Update User with proper redirect keys for some reason this line doesn't work.
        add_user_meta($the_user, 'rpr_redirect_key', '/hubpage/' . $new_user_name, true);
    }

}
add_action('user_register', 'after_registration');

帮助将不胜感激。

Answer 1

在行中

add_user_meta( $the_user, 'rpr_redirect_key', '/hubpage/' . $new_user_name, true);

$the_user不是ID。 试试$the_user->ID或$user_id
