我的问题是我无法将jquery中的值发布到

我的控制器文件很简单,如下所示。。。

用户_控制器.php

<?php 

class UsersController extends AppController

{
       var $name = "Users";
       var $uses = null;           //if no DB connection is reuired……….



       function index()
       {

       }

       function login()
       {
                       print_r($this->params['form']);
                       echo "<br/>";
                       echo "<br/>";
                       echo "<br/>";
                       print_r($_REQUEST);
                       echo "<br/>";
                       echo "<br/>";
                       echo "<br/>";
                       print_r($_POST['username']);
                       echo "<br/>";
                       echo "<br/>";
                       echo "<br/>";
                       echo $_POST['data'];
                       echo "<br/>";
                       echo "<br/>";
                       echo "<br/>";
                       print_r($this->data);
                       echo "<br/>";
                       echo "<br/>";
                       echo "<br/>";

         }

}

?>

->我在此控制器中所做的只是尝试输出值 从jquery发布,但没有

->我的登录视图文件如下所示

登录.ctp

<html>
<head>
<?=$html->css('general');?>
<?=$javascript->link('jquery'); ?>
<?=$javascript->link('jquery.form'); ?>
<?=$javascript->link('LoginValidation'); ?>
</head>
<body>
<h1 align="center"><u>Login Page</u></h1>
<form method="post" action="" id="customForm" name="customForm">
<table cellpadding="0" cellspacing="10">
<tr><td>User Name :</td><td><input id="username" name="username"
type="text" /></td><td><span id="usernameInfo"></span></td></tr>
<tr><td>Password :</td><td><input id="password" name="password"
type="password" /></td><td><span id="passwordInfo"></span>
</td></tr>
<tr><td colspan="2" align="right"><input id="submit" name="submit"
type="submit" value="Log In" /></td></tr>
</table>
</form>
</body>
</html>

=============================

没有使用任何帮手, 很抱歉…..但是我很乐意使用这个。。。。

->最后是我的javascript代码登录验证.js风景在哪里

// JavaScript Document
$(document).ready(function(){

//global vars
var form = $("#customForm");
var username = $("#username");
var password = $("#password");
var usernameInfo = $("#usernameInfo");
var passwordInfo = $("#passwordInfo");
var site_url = "http://localhost/jeffery/cake_jquery/";
//http://localhost/jeffery/cake_jquery/users/login  var str = $
("form").serialize();

//On blur
username.blur(validateUserName);
password.blur(validatePassword);

//On key press
username.keyup(validateUserName);
password.keyup(validatePassword);

//On Submitting
form.submit(function(){
       if(validateUserName()  &  validatePassword() )
               {

                       $.ajax({
                                       type: "POST",
                                       url: "http://localhost/jeffery/cake_jquery/users/login",

                                       }

               return false;
