使用ajax验证登录后将用户重定向到他所在的同一页面

Question

I am using this function to validate a user (ajax login) for my wordpress website.

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

                }
            }
        });
        e.preventDefault();
    });

After login the user is redirected to the home page not the page which he was on. I want the user to be redirected to the same page where he came from. How can i do this ?

Any kind help is appreciated.

PHP SOLUTION

I presume you are forming the ajax_login_object array in PHP. Probably using

wp_localize_script( 'your_script', 'ajax_login_object' , $ajax_login_object );

That is the usual WordPress method of passing data to a front end script anyway.

Try this PHP:

$ajax_login_object['redirecturl'] ="//".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']; 

Or try this from http://www.insertcart.com/get-current-page-url-in-wordpress/ :

$ajax_login_object['redirecturl'] = esc_url(the_permalink());

Another alternative from http://mekshq.com/get-current-page-url-wordpress/ is:

global $wp;
$ajax_login_object['redirecturl'] = home_url(add_query_arg(array(),$wp->request));

JavaScript Solution

This is a pure JavaScript solution.

In JS window.location.href returns the current URL of the page. So in your code you could replace

document.location.href = ajax_login_object.redirecturl;

with

document.location.href = window.location.href;

    function ajax_login_init(){
  wp_register_script('ajax-login-script', get_template_directory_uri() . '/ajax-login-script.js', array('jquery'));
  wp_enqueue_script('ajax-login-script');
  $ajax_login_object  ="//".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']; 
  wp_localize_script('ajax-login-script', 'ajax_login_object', array(
    'ajaxurl' => admin_url('admin-ajax.php'),  
    'redirecturl' =>   $ajax_login_object, //this line for same redirect
  ));
  // Enable the user with no privileges to run ajax_login() in AJAX
  add_action('wp_ajax_nopriv_ajaxlogin', 'ajax_login');
}
