Question

我是CakePHP的新手，我已经从他们的www中学习了教程。现在我正在进行简单的应用程序并且我坚持验证表单，我读到了验证表单here。

控制器：

class DevicesController extends AppController {
   public $helpers = array('Html', 'Form', 'Session');
   public $components = array('Session');

   public function add()
   {
     if ($this->request->is('post')) {
        $this->Device->create();
        $this->Device->set($this->request->data);

        if ($this->Device->validates()) {
                if ($this->Device->save($this->request->data)) {
                    $this->Session->setFlash(__('feedback'));
                    return $this->redirect(array('action' => 'index'));
                } else {
                // didn't validate logic
                $this->Session->setFlash($this->Device->validationErrors);
                }
        }

    $this->Session->setFlash(__('feedback'));
    }
}

型号：

class Device extends AppModel {
public $validate = array(
    'user' => array(
        'alphaNumeric' => array(
            'rule'     => 'alphaNumeric',
            'required' => true,
            'message'  => 'Alphabets and numbers only'
        ),
        'between' => array(
            'rule'    => array('between', 5, 15),
            'message' => 'Between 5 to 15 characters'
        )
    ),
    'manufacturer' => array(
        'rule'       => 'date',
        'message'    => 'Enter a valid date',
        'allowEmpty' => true
    ),
    'mac' => array(
        'required' => array(
            'rule' => array('notEmpty'),
            'message' => 'Nick name is required.'
        )
    )
);}

查看：

echo $this->Form->create('Device');
echo $this->Form->input('user', array('label' => 'Urzytkownik'));
echo $this->Form->input('mac', array('label' => 'MAC'));
echo $this->Form->input('manufacturer', array('label' => 'Producent'));

即使我不填写表单，它也成功通过了验证过程。我在这里做错了什么？

Answer 1

试试这个代码......

if ($this->Device->validates()) {
    if ($this->Device->save($this->request->data)) {
        $this->Session->setFlash(__('feedback'));
        return $this->redirect(array('action' => 'index'));
    } else {
        // didn't validate logic
        $this->Session->setFlash($this->Device->validationErrors);
    }
} else {       
    $errors = $this->Device->validationErrors;
}

Answer 2

使用

if ($this->Device->save($this->request->data)) {

经过验证后没有意义。

可以通过一个简单的电话一起完成：

if ($this->request->is('post')) {
    $this->Device->create();
    if ($this->Device->save($this->request->data)) {
        $this->Session->setFlash(__('feedback'));
        return $this->redirect(array('action' => 'index'));
    }
    // didn't validate logic - note that validationErrors is an array!
    $this->Session->setFlash($this->Device->validationErrors);
}

或在这种情况下使用正确保存：

$this->Device->save(null, false)

（避免二次验证）。

注意：第一个是清洁选项。

这种方法在这里是错误的..

验证失败后，您将在validates的else块中收到验证错误。但你在验证块本身访问它是不正确的。

它应该是这样的。

if ($this->Device->validates()) {
    // successful validation
} else {
    // you'll get the validation errors here
}

现在生成的代码应该是

if ($this->Device->validates()) {
    if ($this->Device->save($this->request->data, false)) { // setting 2nd param to false thus no need to validate again.
        $this->Session->setFlash(__('feedback'));
        return $this->redirect(array('action' => 'index'));
    } 
} else {
    // didn't validate logic
    $this->Session->setFlash($this->Device->validationErrors);
}

**Try the code.....**

<?php
if ($this->request->is('POST')) {
                $this->Device->create();
                       if ($this->Device->save($this->data)) {
$this->Session->setFlash(__('Data has been save.'));
}
}
 ?>
