php - Change user metadata on registration (show_admin_bar_front = false)

admin管理员组

文章数量:1336106

This is my first contact with WP Development, and I'm trying to not display the WP admin bar after the registration. Since it's metadata called 'show_admin_bar-front', I'm updating that right after creating the user.

 if(count($error) == 0) {
            wp_create_user( $username, $password, $email);
            $user_id = get_current_user_id();
            update_user_meta($user_id, 'show_admin_bar_front', 'false');
            echo "User Created Successfully!";
            exit();
        }

As you can see, in the chunk above, I try to get the user ID right after creating the user and then updating the pointed metadata ('true' as default). Probably I'm doing something pretty stupid. Could someone enlighten me? Bellow, the full code.

 <?php
    /*
    Template Name: Registration
    */
    get_header();
    global $wpdb;

    if($_POST) {

        $username = $wpdb->escape($_POST['txtUsername']);
        $email = $wpdb->escape($_POST['txtEmail']);
        $password = $wpdb->escape($_POST['txtPassword']);
        $ConfPassword = $wpdb->escape($_POST['txtConfirmPassword']);


    $error = array();
        if(strpos($username, '') !==FALSE) {
            $error['username_space'] = "Username has space!";
        }

        if(empty($username)) {
            $error['username_empty'] = "Username is empty!";
        }

        if(username_exists($username)) {
            $error['username_exists'] = "Username already exists!";
        }

        if(!is_email($email)) {
            $error['email_valid'] = "Please, add a valid e-mail.";
        }

        if(email_exists($email)) {
            $error['email_existence'] = "This e-mail is already registered.";
        }

        if(strcmp($password, $ConfPassword) !==0) {
            $error['password'] = "Password don't match!";
        }

        if(count($error) == 0) {
            wp_create_user( $username, $password, $email);
            $user_id = get_current_user_id();
            update_user_meta($user_id, 'show_admin_bar_front', 'false');
            echo "User Created Successfully!";
            exit();
        } else {
            print_r($error);
        }
    }

    ?>

If you want to update meta on registration like this I think a better option would be to use the register_new_user hook with add_action. https://developer.wordpress/reference/hooks/register_new_user/

So something like:

add_action('register_new_user','my_update_meta',10,1);


function my_update_meta($user_id){

 update_user_meta($user_id, 'show_admin_bar_front', false);


}

If in doubt, hooks/filters/actions tend to be the best option for WordPress work.
