CakePHP Post参数

Question

我在cakephp中遇到输入/接收输入表单的问题

// /View/Services/add_services.ctp
....
<?php echo $this->Form->create('Service', array('action'=>'addServices'))?>
<?php echo $this->Form->input("service_name", array('label'=>false, 'div'=>false, 'class'=>"umstyle5"))?>
<?php echo $this->Form->Submit(__("Add service Type"))?>
<?php echo $this->Form->end();?>

// /Controller/ServicesController
....
public function addServices(){
    ....
    $service_name = $_POST[service_name];
    ....
}

问题是我收到此错误：

未定义的索引：service_name [APP / Controller / ServicesController]

有什么问题？ 谢谢！

Answer 1

使用$ this-＆gt; request-＆gt; data。

 public function addServices(){
....
  $service_name = $this->request->data['Service']['service_name'];
....
 }

Answer 2

我建议你正确查看Documentation，

有明确提到我们可以获取数据......

   //Controller/RecipesController.php:
   public function edit($id = null) {
       if (empty($this->request->data)) {
          $this->request->data = $this->Recipe->findById($id);
       } else {
          // Save logic goes here
       }
    }
