the data validation is always return true in cakephp

Question

the data validation in my User Model always return true. Can anybody tell me why? The Model: user.php

class User extends AppModel {

var $name = "User";

public $validate = array(

    "username" => array(
        "rule" => "notBlank",
        "message" => "Please enter title !",
    ),
    "password" => array(
        "rule" => "notBlank", // tập luật là không rỗng
        "message" => "Please enter info !", // thông báo khi có lỗi
    ));


}

UsersController:

if(($this->request->is('post'))) {

        $this->loadModel('User');
        $this->User->set($this->data);
        echo "</br> vao ".$this->User->validates();
        if($this->User->validates()){
            echo "</br>".$this->User->validates();
            $this->Session->setFlash("Data is avaliable !");

        }else{
            $error = $this->User->validationErrors;
            $this->Session->setFlash("Data is mot avaliable !");
            echo"not validate";
        }

But return is alway is true.

I tried to run cakephp 2..7.2 and 2.6.0 but the result is still the same.

In CakePHP 2.x the request/form data is accessed via $this->request->data not $this->data. So you need to change the line where you set the model's data using $this->User->set() to use $this->request->data:-

if ($this->request->is('post')) {
        $this->User->set($this->request->data);
        if ($this->User->validates()){
            $this->Session->setFlash("Data is avaliable !");
        } else{
            $this->Session->setFlash("Data is not avaliable !");
        }
}

As long as you're sticking to CakePHP conventions there is no need to load the User model in the UsersController as it should be auto-loaded. So you can remove $this->loadModel('User').

If you're using the notBlank validation rule make sure you are using CakePHP 2.7 as this rule does not exist in earlier versions of Cake. For CakePHP 2.6 use the notEmpty rule.
