hopefully you’ve found the answer already. Here’s our solution, for your reference. 😀
The following code should add User Registration via REST API to your WordPress Website. It supports Registration of ‘subscriber’ and ‘customer’.
Add it to your function.php
add_action('rest_api_init', 'wp_rest_user_endpoints');
/**
* Register a new user
*
* @param WP_REST_Request $request Full details about the request.
* @return array $args.
**/
function wp_rest_user_endpoints($request) {
/**
* Handle Register User request.
*/
register_rest_route('wp/v2', 'users/register', array(
'methods' => 'POST',
'callback' => 'wc_rest_user_endpoint_handler',
));
}
function wc_rest_user_endpoint_handler($request = null) {
$response = array();
$parameters = $request->get_json_params();
$username = sanitize_text_field($parameters['username']);
$email = sanitize_text_field($parameters['email']);
$password = sanitize_text_field($parameters['password']);
// $role = sanitize_text_field($parameters['role']);
$error = new WP_Error();
if (empty($username)) {
$error->add(400, __("Username field 'username' is required.", 'wp-rest-user'), array('status' => 400));
return $error;
}
if (empty($email)) {
$error->add(401, __("Email field 'email' is required.", 'wp-rest-user'), array('status' => 400));
return $error;
}
if (empty($password)) {
$error->add(404, __("Password field 'password' is required.", 'wp-rest-user'), array('status' => 400));
return $error;
}
// if (empty($role)) {
// $role="subscriber";
// } else {
// if ($GLOBALS['wp_roles']->is_role($role)) {
// // Silence is gold
// } else {
// $error->add(405, __("Role field 'role' is not a valid. Check your User Roles from Dashboard.", 'wp_rest_user'), array('status' => 400));
// return $error;
// }
// }
$user_id = username_exists($username);
if (!$user_id && email_exists($email) == false) {
$user_id = wp_create_user($username, $password, $email);
if (!is_wp_error($user_id)) {
// Ger User Meta Data (Sensitive, Password included. DO NOT pass to front end.)
$user = get_user_by('id', $user_id);
// $user->set_role($role);
$user->set_role('subscriber');
// WooCommerce specific code
if (class_exists('WooCommerce')) {
$user->set_role('customer');
}
// Ger User Data (Non-Sensitive, Pass to front end.)
$response['code'] = 200;
$response['message'] = __("User '" . $username . "' Registration was Successful", "wp-rest-user");
} else {
return $user_id;
}
} else {
$error->add(406, __("Email already exists, please try 'Reset Password'", 'wp-rest-user'), array('status' => 400));
return $error;
}
return new WP_REST_Response($response, 123);
}
IMHO, a more better way would to include the additional function as a seperate plugin. So even when your user changed theme, your api calls won’t be affected.
Therefore I’ve developed a plugin for User Registration via REST API in WordPress. Better yet, it supports creating ‘customer’ for WooCommerce too!
