Question

我是带有版本2.0的cakePHP框架的新手，我的问题是当我保存数据或插入新记录时，字段为空或没有数据要保存我该如何解决这个问题。

我的模特

class Post extends AppModel{
    public $name = 'posts';
}

我的控制器

public function add(){
   if($this->request->is('post')){
        $this->Post->create();
        if($this->Post->save($this->request->data)){
            $this->Session->setFlash('The posts was saved');
            $this->redirect('index');
        }       
    }
}

我的观点

echo $this->Form->create('Create Posts');
echo $this->Form->input('title');
echo $this->Form->input('body');
echo $this->Form->end('Save Posts');

您需要将验证规则放在Post模型中，然后您可以在save之前在控制器操作中检查验证数据到模型中。请参阅以下Model和controller

在模型中

class Post extends AppModel{
    public $name = 'posts';

    public $validate = array(
        'title' => array(
            'alphaNumeric' => array(
                'rule' => 'alphaNumeric',
                'required' => true,
                'message' => 'This is can'\t blank'
            ),

        ),
        'body' => array(
            'alphaNumeric' => array(
                'rule' => 'alphaNumeric',
                'required' => true,
                'message' => 'This is can'\t blank'
            ),            
        ),
    );
}

在控制器中

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

        if ($this->Post->validates()) {
        // it validated logic
            if($this->Post->save($this->request->data)){
                $this->Session->setFlash('The posts was saved');
                $this->redirect('index');
            }
        } else {
            // didn't validate logic
            $errors = $this->Post->validationErrors;
        }       
    }
}
