php - 比较规则 yii2 无法正常工作

Question

我的规则方法如下:

public function rules()
{
    return [
        [['username', 'email', 'password'],'filter', 'filter' => 'trim'],
        [['username', 'email', 'password'],'required', 'message' => '{attribute} can not be empty'],
        ['username', 'string', 'min' => 2, 'max' => 255],
        ['password', 'string', 'min' => 6, 'max' => 255],
        ['password_repeat', 'required', 'message' => 'This field can not be empty'],
        ['password_repeat', 'compare', 'compareAttribute'=>'password', 'message'=>"Passwords don't match", 'skipOnError' => true],
        ['username', 'unique',
            'targetClass' => User::className(),
            'message' => 'This name is already used.'],
        ['email', 'email'],
        ['email', 'unique',
            'targetClass' => User::className(),
            'message' => 'This name is already used.'],
    ];
}

我的 View 代码是这样的:

<?php $form = ActiveForm::begin(['action' => 'login/register']); ?>
        <?= $form->field($registration, 'username',
            ['template' => '<div class="uk-form-row">
                                {input}{error}
                                </div>'])
            ->textInput(['id' => 'register_username', 'class' => 'md-input']) ?>

        <?= $form->field($registration, 'password',
            ['template' => '<div class="uk-form-row">
                            {input}{error}
                            </div>'])
            ->passwordInput(['id' => 'register_password', 'class' => 'md-input']) ?>

        <?= $form->field($registration, 'password_repeat',
            ['template' => '<div class="uk-form-row">
                            {input}{error}
                            </div>'])
            ->passwordInput(['id' => 'register_password_repeat', 'class' => 'md-input']) ?>

        <?= $form->field($registration, 'email',
            ['template' => '<div class="uk-form-row">
                            {input}{error}
                            </div>'])
            ->textInput(['id' => 'register_email', 'class' => 'md-input']) ?>
        <div class="uk-margin-medium-top">
            <button class="md-btn md-btn-primary md-btn-block md-btn-large">Sign in</button>
        </div>
        <?php ActiveForm::end(); ?>

当我填写所有给定字段时，即使第一次是正确的，重复密码时也会出现错误密码不匹配。我的验证规则有问题还是 Yii Validator 中的错误？

UPD:我已尝试'skipOnError' => true。我发现它是类似问题的答案，但它仍然无法按预期工作。

UPD:我在控制台中做了一些验证:

var a = $('#register_password')
undefined
a.val()
"Halloha"
var b = $('#register_password_repeat')
undefined
b.val()
"Halloha"

但它仍然显示密码不匹配错误消息

Answer 1

尝试使用这样的规则

 // validates if the value of "password" attribute equals to that of 
 ['password', 'compare', 'message'=>"Passwords don't match"],

它会自动将密码值与属性password_repeat进行比较，而不是按照文档中所述的其他顺序进行比较。
