Is it possible to create a sign up form that can work through WP REST API for visitors to be able to create accounts on my site?
I can create such a form and use it to create new users. This works with wp_rest nonce when I am logged in as administrator.
But if there is a visitor which is not logged in, the same form does not work of course. I think this is a question of authentication. Can you suggest a general idea how this can work? How can I allow visitors to be able to sign up with REST API?
Hopefully you've found your answers already!
If not, just paste the following code in your theme's function.php, and it should work like a charm.The following code should add User Registration via REST API to your WordPress Website. It supports Registration of 'subscriber' and 'customer'. Source code also available on Github.
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!
WP REST User, check it out if you want.
You can use this two plugins for this:
WordPress JSON API plugin
and
JSON API User
These both plugins will help to get the job done.You will need nonce ID to call registration API,which will be given by plugin.
this will explain , how it works!!
