Question

我正在使用CakePHP v2.2.1稳定版。我有UsersController行动add()。我正在尝试通过ajax（从主页到/users/add）发送用户信息并保存数据。我的代码是这样的：

// /app/View/Pages/home.ctp
<?php
   $data = array('User' => array('username' => 'vegeta_super_sayajin',
    'password' => 'over9000!', 'email' => 'vegeta@supersayajin.com',
    'profile_pic' => '/home/pics/scouter.jpg', 'firstname' => 'Vegeta',
    'lastname' => 'Vegeta', 'level_id' => '9001'));
?>
<script type="text/javascript">
    var data = <?php echo json_encode($data); ?> //convert $data into json format
    $.ajax({url: '/users/add', data: "data="+data, type: 'post'});
</script>

如何在UsersController中收到此数据，以便我可以处理并保存？

目前，我正在尝试：

// /app/Controller/UsersController.php
function add() {
    if($this->request->is('post') {
        //returns "Error: [object Object] in logfile
        $this->log($this->request->data);
    } else {
        $this->Session->setFlash(__("The user could not be saved :("));
    }
    $this->autoRender = false;
}

$this->log($this->request->data)会在Error: [object Object]文件中返回/app/tmp/logs/error.log，并且此用户信息在$this->request->params的任何索引中都不存在。到目前为止，我所有的谷歌搜索都只返回了复杂的cakephp v1.3技术。怎么在cakephp v2.2.1中完成？

您可以尝试以下代码。它会对你有用。

<?php
$data = array(
'User' => array(
    'username' => 'vegeta_super_sayajin', 
    'password' => 'over9000!',
    'email' => 'vegeta@supersayajin.com', 
    'profile_pic' => '/home/pics/scouter.jpg',
    'firstname' => 'Vegeta', 
    'lastname' => 'Vegeta', 
    'level_id' => '9001')
    );   
?>
<script type="text/javascript">
var data = [<?php echo json_encode($data); ?>] //convert $data into json format
$.ajax({
    url: 'checks/add', 
    data: "data="+JSON.stringify(data), 
    type: 'post'});
</script>

在你的控制器代码中：

// /app/Controller/UsersController.php
function add() {
if($this->request->is('post') {
    $this->log(json_encode($this->request->data, true)); //returns "Error: [object Object] in logfile
} else {
    $this->Session->setFlash(__("The user could not be saved :("));
}
$this->autoRender = false;
}

这是json_decode documentation。第二个参数true会将对象转换为数组。
