WordPress ajax login without using a plugin

30.Sep.2017 | , ,

A nice solution for a custom WordPress Ajax login form without using a plugin.

Place this anywhere you would like the form to show in your WordPress template.

<form id="login" action="login" method="post">
 <h1>Site Login</h1>
 <p class="status"></p>
 <label for="username">Username</label>
 <input id="username" type="text" name="username">
 <label for="password">Password</label>
 <input id="password" type="password" name="password">
 <a class="lost" href="<?php echo wp_lostpassword_url(); ?>">Lost your password?</a>
 <input class="submit_button" type="submit" value="Login" name="submit">
 <a class="close" href="">(close)</a>
 <?php wp_nonce_field( 'ajax-login-nonce', 'security' ); ?>

Send the user info via Ajax

Place the following 2 code snippets in your functions.php file:

function ajax_login_init(){

wp_register_script('ajax-login-script', get_template_directory_uri() . '/ajax-login-script.js', array('jquery') );

wp_localize_script( 'ajax-login-script', 'ajax_login_object', array(
'ajaxurl' => admin_url( 'admin-ajax.php' ),
'redirecturl' => home_url(),
'loadingmessage' => __('Sending user info, please wait...')

// Enable the user with no privileges to run ajax_login() in AJAX
add_action( 'wp_ajax_nopriv_ajaxlogin', 'ajax_login' );

// Execute the action only if the user isn't logged in
if (!is_user_logged_in()) {
add_action('init', 'ajax_login_init');

And this…

function ajax_login(){

// First check the nonce, if it fails the function will break
check_ajax_referer( 'ajax-login-nonce', 'security' );

// Nonce is checked, get the POST data and sign user on
$info = array();
$info['user_login'] = $_POST['username'];
$info['user_password'] = $_POST['password'];
$info['remember'] = true;

$user_signon = wp_signon( $info, false );
if ( is_wp_error($user_signon) ){
echo json_encode(array('loggedin'=>false, 'message'=>__('Wrong username or password.')));
} else {
echo json_encode(array('loggedin'=>true, 'message'=>__('Login successful, redirecting...')));


Then place this in your custom javascript file…

jQuery(document).ready(function($) {

// Show the login dialog box on click
$('a#show_login').on('click', function(e){
$('body').prepend('<div class="login_overlay"></div>');
$('div.login_overlay, form#login a.close').on('click', function(){

// Perform AJAX login on form submit
$('form#login').on('submit', function(e){
$('form#login p.status').show().text(ajax_login_object.loadingmessage);
type: 'POST',
dataType: 'json',
url: ajax_login_object.ajaxurl,
data: {
'action': 'ajaxlogin', //calls wp_ajax_nopriv_ajaxlogin
'username': $('form#login #username').val(),
'password': $('form#login #password').val(),
'security': $('form#login #security').val() },
success: function(data){
$('form#login p.status').text(data.message);
if (data.loggedin == true){
document.location.href = ajax_login_object.redirecturl;


Thats it!
