Auto create username on registration

@anilreddy0102

this can also be created once the user submits the registration form

This code snippet will create your prefixed username with 5 random digits at Registration.

Add the {username} email placeholder to the Email Activation email template.

add_filter( 'um_add_user_frontend_submitted', 'my_custom_auto_create_username', 10, 2 );

	function my_custom_auto_create_username( $args, $form_data ) {

		if( $args['mode'] == 'register' ) {
			$prefix = 'ABCD-';
			$args['user_login'] = $prefix . rand( 10000, 99999 );
			while( username_exists( $args['user_login'] )) {
				$args['user_login'] = $prefix . rand( 10000, 99999 );
			}
		}
		return $args;
	}

You install the code snippet by adding it
to your active theme’s functions.php file
or use the “Code Snippets” Plugin

Thanks for the prompt reply. I have added the code to my theme’s functions.php file. When I submit the form, username is automatically using the first name and last name. It’s not working as expected. Please help. FYI, I didn’t add the username field to the form. My form has name, surname, email, mobile and password fields.

You are right the old code snippet did nothing with the username.
You can try this code snippet instead

add_filter( 'um_add_user_frontend_submitted', 'my_custom_auto_create_username', 10, 2 );

function my_custom_auto_create_username( $args, $form_data ) {

    if ( isset( $form_data['mode'] ) && $form_data['mode'] == 'register' ) {
        $prefix = 'ABCD-';
        $args['user_login'] = $prefix . rand( 10000, 99999 );
        while( username_exists( $args['user_login'] )) {
            $args['user_login'] = $prefix . rand( 10000, 99999 );
        }
    }
    return $args;
}

This worked. Thanks a lot. Hope this will continue working even with future plugin updates as well?
