Automatically generate username based on user ID in WooCommerce

I’m working on a WooCommerce project where each user have an ID number. I would like to use the default WooCommerce username field for this user ID.

When creating an account, can I automatically generate an account username for the customer based on their user ID?

img

Example:
User ID = 101,
Auto generated Username = 101

Is it possible?

Any help would really be appreciated. Thanks!

    Option 1

    You can edit the wp_insert_user function that creates the user and change parameters. This function requires an array (or object) of user data to create the user so you just add whatever you want to user_login. All parameters and examples here.

    Option 2

    If you can’t edit the wp_insert_user function you can always call a custom SQL query to update user_login:

    $wpdb->update($wpdb->users, array('user_login' => $new_user_login), array('ID' => $user_id));

    Ideally use a hook/action just after user registration.

    First of all, make sure that the following option is checked via the WooCommerce settings

    enter image description here

    Normally than you could use the woocommerce_new_customer_username filter hook to change the generated username.

    Copied from includes/wc-user-functions.php

    /**
 * Filter new customer username.
 *
 * @since 3.7.0
 * @param string $username      Customer username.
 * @param string $email         New customer email address.
 * @param array  $new_user_args Array of new user args, maybe including first and last names.
 * @param string $suffix        Append string to username to make it unique.
 */
return apply_filters( 'woocommerce_new_customer_username', $username, $email, $new_user_args, $suffix );

    However, you want to determine the $username based on the $user_id,
    but the $user_id is determined after data such as username, email address, etc. has been added via wp_insert_user()

    So the solution is to update the $username based on the $user_id immediately after a user is registered, and this can be done via:

    Copied from wp-includes/user.php (WordPress)

    /**
 * Fires immediately after a new user is registered.
 *
 * @since 1.5.0
 *
 * @param int $user_id User ID.
 */
do_action( 'user_register', $user_id );

    And

    • wpdb – WordPress database access abstraction class.

    • update_user_meta() – Update user meta field based on user ID.

    So you get:

    function action_user_register( $user_id ) {
    global $wpdb;
    
    // Set new name + nickname
    $new_name = 'something_' . $user_id;
    
    // Update user user_login
    $wpdb -> update( $wpdb -> users, 
        array( 'user_login' => $new_name, 'user_nicename' => $new_name, 'display_name' => $new_name ), 
        array( 'ID' => $user_id )
    );
    
    // Update user meta
    update_user_meta( $user_id, 'first_name', $new_name );
    update_user_meta( $user_id, 'nickname', $new_name );
} 
add_action( 'user_register', 'action_user_register', 10, 1 );

    Note: Know that a customer/user can change some of these adjustments via his profile (my account), if you do not want this, you will have to make additional adjustments.
