Wordpress insert new user not adding in backend - php

Question

When signing up on my dev site, a bug is here that i cant seem to figure out. I am allowed to pass the validation when signing up. But when i use the submit button to create the account, it seems to not want to log any information into the database. I get the logged in message but that's it, i can just recreate the
same over ad over again.
add_action( 'wp_ajax_nopriv_ajaxregister', 'ajax_register' );
add_action( 'wp_ajax_ajaxregister', 'ajax_register' );
function ajax_register() {
$title = $_POST['titles'];
$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
$email = $_POST['user_email'];
$user_pass = $_POST['user_pass'];
$confirm_pass = $_POST['confirm_pass'];
$agree_tc = $_POST['agree_tc'];
$nationality = $_POST['nationality'];
$username = $_POST['user_email'];//strtolower($firstname) . '-' . strtolower($lastname);
$phone = '+' . $_POST['country_code'] . $_POST['phone'];
//$address = $_POST['address'];
if ($user_pass != $confirm_pass || !is_email($email) || $agree_tc != 'true') {
echo json_encode(array('loggedin' => false, 'message' => __('There are some errors')));
} else {
$user = array(
'user_login' => $username,
'user_pass' => $user_pass,
'first_name' => $firstname,
'last_name' => $lastname,
'user_email' => $email,
'role' => 'client'
);
$user_id = wp_insert_user($user);
if (is_wp_error($user_id)) {
$error_string = $user_id->get_error_message();
echo json_encode(array('loggedin' => false, 'message' => $error_string));
} else {
update_user_meta($user_id, 'user_num', $phone);
update_user_meta($user_id, 'user_nat', $nationality);
update_user_meta($user_id, 'display_titles',$title);
//update_user_meta($user_id, 'user_address', $address);
$creds = array(
'user_login' => $username,
'user_password' => $user_pass
);
$user_signon = wp_signon($creds, false);
echo json_encode(array('loggedin' => true, 'message' => __('Login successful, redirecting...')));
}
}
die();
}
EDIT .
The markup was perfectly fine, however after going through my repo of changes. The display titles was not getting parsed.
function ajax_register() {
$title = $_POST['titles'];
$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
$email = $_POST['user_email'];
$confirm_email = $_POST['confirm_email'];
$user_pass = $_POST['user_pass'];
$confirm_pass = $_POST['confirm_pass'];
$agree_tc = $_POST['agree_tc'];
$nationality = $_POST['nationality'];
$username = $_POST['user_email'];
$phone = '+' . $_POST['country_code'] . $_POST['phone'];
if ($user_pass != $confirm_pass || !is_email($email) || !is_numeric($_POST['phone']) || $agree_tc != 'true') {
echo json_encode(array('loggedin' => false, 'message' => __('There are some errors')));
} else {
$user = array(
'user_login' => $username,
'user_pass' => $user_pass,
'first_name' => $firstname,
'last_name' => $lastname,
'user_email' => $email,
'display_titles'=>$title, // THIS WAS MISSING
'role' => 'client'
);
$user_id = wp_insert_user($user);
if (is_wp_error($user_id)) {
$error_string = $user_id->get_error_message();
echo json_encode(array('loggedin' => false, 'message' => $error_string));
} else {
update_user_meta($user_id, 'user_num', $phone);
update_user_meta($user_id, 'user_nat', $nationality);
update_user_meta($user_id, 'display_titles',$title);
//update_user_meta($user_id, 'user_address', $address);
$creds = array(
'user_login' => $username,
'user_password' => $user_pass
);
$user_signon = wp_signon($creds, false);
echo json_encode(array('loggedin' => true, 'message' => __('Login successful, redirecting...')));
}
}
die();
