Phalcon验证方案

Question

我以前用过Yii框架。我想用Phalcon做项目。我找不到Phalcon的验证方案。在Phalcon上正确实现它的最佳方法是什么？

提前谢谢。

Answer 1

任何数据验证：

<?php

use Phalcon\Validation\Validator\PresenceOf,
    Phalcon\Validation\Validator\Email;

$validation = new Phalcon\Validation();

$validation->add('name', new PresenceOf(array(
    'message' => 'The name is required'
)));

$validation->add('email', new PresenceOf(array(
    'message' => 'The e-mail is required'
)));

$validation->add('email', new Email(array(
    'message' => 'The e-mail is not valid'
)));

$messages = $validation->validate($_POST);
if (count($messages)) {
    foreach ($messages as $message) {
        echo $message, '<br>';
    }
}

http://docs.phalconphp.com/en/1.2.6/reference/validation.html

如果您正在使用模型：

<?php

use Phalcon\Mvc\Model\Validator\InclusionIn,
    Phalcon\Mvc\Model\Validator\Uniqueness;

class Robots extends \Phalcon\Mvc\Model
{

    public function validation()
    {

        $this->validate(new InclusionIn(
            array(
                "field"  => "type",
                "domain" => array("Mechanical", "Virtual")
            )
        ));

        $this->validate(new Uniqueness(
            array(
                "field"   => "name",
                "message" => "The robot name must be unique"
            )
        ));

        return $this->validationHasFailed() != true;
    }

}

模型也有事件，因此可以在这些函数中添加所需的任何逻辑：

我想使用CRUD的表单，因为它们非常动态和可重用。您可以使用选项在表单中实现这一点。

您可以传递其他选项，以形成和执行类似场景的操作。

您可以在这里检查表单构造函数。

Form.html

在控制器中，您可以传递$options。

<?php

use Phalcon\Mvc\Controller;

class PostsController extends Controller
{
    public function insertAction()
    {
        $options = array();
        $options['scenario'] = 'insert';
        $myForm = new MyForm(null, $options);  

        if($this->request->hasPost('insert')) {

            // this will be our model
            $profile = new Profile(); 

            // we will bind model to form to copy all valid data and check validations of forms
            if($myForm->isValid($_POST, $profile)) {
                $profile->save();
            }
            else {
                echo "<pre/>";print_r($myForm->getMessages());exit();
            }
        } 
    }

    public function updateAction()
    {
        $options = array();
        $options['scenario'] = 'update';
        $myForm = new MyForm(null, $options);

    }
}

你的表格应该看起来像这样

<?php   

// elements
use Phalcon\Forms\Form;
use Phalcon\Forms\Element\Text;

// validators
use Phalcon\Validation\Validator\PresenceOf;    

class MyForm extends Form {


    public function initialize($entity = null, $options = null) {    

        $name = new Text('first_name');
        $this->add($name);
        if($options['scenario'] == 'insert') {
            // at the insertion time name is required
            $name->addValidator(new PresenceOf(array('message' => 'Name is required.')));
        }
        else {
            // at the update time name is not required
            // as well you can add more additional validations
        }

    }
}

现在，您可以添加多个场景并根据场景执行操作。
