CakePHP 3：验证表单

Question

我需要验证一个表单，我不知道具体该怎么做。我试图在Model/Users.php和Model/Table/UserTables.php中进行验证，但没有任何结果。

有人可以帮助我吗？

register.ctp

<br> 
<div class="index large-4 medium-4 large-offset-4 medium-offset-4 columns"> 
    <div class="panel"> 
     <h2 class="text-center">Cadastro</h2> 
     <?= $this->Form->create(); ?> 

      <?= $this->Form->input('nome'); ?> 
      <?= $this->Form->input('email'); ?> 
      <?= $this->Form->input('password'); ?> 
      <?= $this->Form->submit('Cadastrar', array('class' => 'button')); ?> 


     <?= $this->Form->end(); ?> 
    </div> 
</div>  

我不知道exaclty，我可以把这个：

public $validate = array(
    //campo que deve ser validado 
    ‘nome’ => array(
     //alias da validação 
     ‘notempty’ => array( 
    ‘rule’=>’notempty’,//validação para não aceitar vazio 
    ‘message’=>”Você deve preencher este campo”//erro 
    ) 
    ), 
    ‘idade’ => array(
    ‘notempty’ => array(
    ‘rule’ => ‘notempty’, 
    ‘message’ => ‘Você deve preencher este campo’ 
    ), 
    ‘numeric’ => array(
    ‘rule’ => ‘numeric’, 
    ‘message’ => ‘Você deve preencher este campo’ 
    ) 
) 
); 
} 

验证上UsersTable.php只适用于 “增加” 的形式：

public function validationDefault(Validator $validator) 
    { 
     $validator 
      ->integer('id') 
      ->allowEmpty('id', 'create'); 

     $validator 
      ->requirePresence('nome', 'create') 
      ->notEmpty('nome'); 

     $validator 
      ->email('email') 
      ->requirePresence('email', 'create') 
      ->notEmpty('email'); 

     $validator 
      ->requirePresence('password', 'create') 
      ->notEmpty('password'); 



     return $validator; 
    } 

Answer 1

您会希望将验证放入模型中。它看起来像您所使用的验证语法的CakePHP 2，但你的标题说，您使用的版本3，你可以看到，在这里：http://book.cakephp.org/2.0/en/models/data-validation.html#simple-rules

下面是CakePHP的3验证文档：http://book.cakephp.org/3.0/en/core-libraries/validation.html

你”必须在这添加到模型

use Cake\Validation\Validator; 

$validator = new Validator(); 

，并从那里，你可以添加像

$validator->notEmpty('title', 'Please fill this field')
