Why does the YII2 custom validator not execute?

This is the login form model

class LoginForm extends Model{    public $account;    public $password;    /**     * @return array the validation rules.     */    public function rules()    {        return [            ['account','app\components\NameValidator','maxLen'=>12]        ];    }}

App\components\namevalidator is a validator that I have customized:

  namespace App\components;use Yii\validators\validator;class    Namevalidator extends validator{public $minLen = 2;    Public $maxLen = 14;    Public $charset = ' utf-8 ';    Public $message;        Public Function Validatevalue ($value) {file_put_contents (' hello.txt ', ' 123 ');//test method is executed.        $enPattern = '/[a-z]/i ';        $zhPattern = '/^[\x{4e00}-\x{9fa5}]*$/u ';        $valid =false;        $zhStr =preg_replace ($enPattern, ", $value, -1, $count);        $enLen = $count;        $zhLen =mb_strlen ($zhStr, $this->charset);        $len = $enLen + $zhLen * *; if ($len > $this->maxlen | | $len < $this->minlen) {if (! $this->message) $this->message= ' character count is not        Correct ';        }else if (!preg_match ($zhPattern, $zhStr)) {if (! $this->message) $this->message= ' character unqualified ';        }else{$valid =true; } return $valid?    Null: [$this->message,[]]; }}

In Passportcontroller, call LoginForm's Validate method for validation:

namespace app\controllers;use Yii;use yii\web\Controller;use app\models\LoginForm;class PassportController extends Controller{    public $enableCsrfValidation=false;    public $layout='@app/views/passport/main.php';    public function actionLogin()    {        if(\yii::$app->request->isPost)        {            $login=new LoginForm();            $login->load(\yii::$app->request->post());            if($login->validate())            {                echo 'valid pass';            }else{                echo $login->errors;            }        }        $this->view->title='登录';        return $this->render('login');    }}

The result is that the Validatevalue method in my custom App\components\namevalidator class is not executed, and the 执行$login->validate() valid pass string is always output in the Actionlogin method. Don't know what's going on here?

I know it's possible to do this with an inline validator, but I want to ask what's going on here? Why is the verification method not implemented here?

1. Validator::validateattribute () and Validator::validatevalue () are two ways to implement

2. Take a closer look at the document

3. Commissioning can be made with Yii::log ()
