javascript - Trouble with Wordpress Ajax Login System - 302 -

i'm trying create simple ajax login system wordpress. unfortunately, every time "wp_signon" function fired, system failed , information have 1 :

post myurl/wp-admin/admin-ajax.php - 302 found  myurl/?login = failed - 200 found 

so, whether try log in informations or not, js script goes in "error part" of ajax function.

can tell me doing wrong? appreciated!

many thanks!

js :

jquery(document).on('submit', loginform, function(event) {      event.preventdefault();      var usernameval = jquery('.modal-login .login-form #user_login').val();     var passwordval = jquery('.modal-login .login-form #user_pass').val();     var remembermefield = jquery('.modal-login .login-form #rememberme');     var securityval = jquery('.modal-login .login-form #security').val();      if ( remembermefield.prop('checked') ) {         var remembermeval = 'true';     } else {         var remembermeval = 'false';     }      jquery.ajax({         type : "post",         url : data_front_end_users_management.ajaxurl,         datatype: 'json',         data: {              action: 'authuserajax',             username: usernameval,              password: passwordval,              rememberme: remembermeval,             security: securityval         },         success: function(data) {              if ( data['answer'] === 1 ) {                  modalalert( msgrow, msgalert, msgcontent, false, 'alert-success', 'alert-danger', data['message'] );               } else {                  modalalert( msgrow, msgalert, msgcontent, false, 'alert-danger', 'alert-success', data['message'] );              }          //end success             },         error: function () {              modalalert( msgrow, msgalert, msgcontent, false, 'alert-danger', 'alert-success', defaulterror );          }      //end ajax     });  //end jquery(document).on('submit', loginform, function(event) }); 

action :

function authuserajax() {      $logincontroller = new felogincontroller();      $value = array();     $value['answer'] = 0;     $value['message'] = '';      $username = trim($_post['username']);     $password = trim($_post['password']);     $rememberme = $_post['rememberme'];     $security = $_post['security'];      if ( $logincontroller->checkauthinfosfilled( $username, $password ) ) {          $user = $logincontroller->userauth( $username, $password, $rememberme );          if ( $user ) {              if ( is_wp_error( $user ) ) {                  $value['answer'] = 0;                 $value['message'] = $user->get_error_message();              } else {                  $value['answer'] = 1;                 $value['message'] = 'success.';              }          //end if ( $user )         } else {              $value['answer'] = 0;             $value['message'] = 'wrong username or password.';          }      } else {          $value['answer'] = 0;         $value['message'] = 'please, enter username , password.';      }      $data = json_encode($value);      die( $data );  //end authuserajax  }  add_action( 'wp_ajax_authuserajax','authuserajax' ); add_action( 'wp_ajax_nopriv_authuserajax','authuserajax' ); 

controller :

public function userauth( $username, $password, $rememberme ) {      if ( check_ajax_referer( 'ajax-login-nonce', 'security' ) ) {          $creds = array();         $creds['user_login'] = $username;         $creds['user_password'] = $password;          if ( $rememberme == 'true' || $rememberme == true ) {             $creds['remember'] = true;         } else {             $creds['remember'] = false;         }          $user = wp_signon( $creds, false );          return $user;      } else {          return false;      }  //end userauth } 

so, after hours of searching, found problem : method in class interfered ajax authentication system.
