How to use symfony's component - validator

采用框架:codeIgniter
前端:Vue js

因使用 Vue js 与 element ui 实现前端,使用 Vue resource 来完全所有的请求,所以 codeIgniter 自带的 Form Validation 类无使用。

想着,自己单独去写一个 validator 浪费太多时间,决定使用第三方库 ** symfony/validator **。

Step #1 通过 Composer 安装 symfony/validator

composer require symfony/validator

Step #2 加载绝对路径中的 autoload.php,代码如下:

require_once APPPATH.'third_party/symfony/vendor/autoload.php';

use Symfony\Component\Validator\Validation;
use Symfony\Component\Validator\Constraints\Length;
use Symfony\Component\Validator\Constraints\NotBlank;


    class User extends MY_Controller
    {
        public function __construct()
        {
            parent::__construct();
            $this->load->helper('url_helper');
            $this->load->model('User_Model');
        }

        public function index()
        {
    
            $validator = Validation::createValidator();

            $violations = $validator->validate('Bernhard', array(
                    new Length(array('min' => 10)),
                    new NotBlank(),
            ));

            if (0 !== count($violations)) {
                // there are errors, now you can show them
                foreach ($violations as $violation) {
                    echo $violation->getMessage().'
'; } }

Step #3 访问 http://www.ci.dev/user/index,输出结果如下:

This value is too short. It should have 10 characters or more.
