需要Yii2制作复选框不起作用

This is my form:

<?php $form = ActiveForm::begin(); ?>

<?php echo $form->field($invite, 'email')->textInput([
    'id' => 'register-email', 
    'placeholder' => Yii::t('UserModule.views_auth_login', 'email')]);
?>

<?php echo $form->field($invite, 'check')->checkbox([
    'id' => 'check', 
    'uncheck' => null])->label(
            Yii::t('UserModule.views_auth_login', 'I have read and accept') . ' <a href="#">' 
            . Yii::t('UserModule.views_auth_login', 'Terms & Conditions') . '</a> ' 
            . Yii::t('UserModule.views_auth_login', 'and') 
            . ' <a href="#">' . Yii::t('UserModule.views_auth_login', 'Privacy Policy') 
            . '</a>' . '.');
?>
    <hr>

    <?php
         echo \humhub\widgets\AjaxButton::widget([
            'label' => Yii::t('UserModule.views_auth_login', 'Register'),
            'ajaxOptions' => [
            'type' => 'POST',
            'beforeSend' => new yii\web\JsExpression('function(){ setModalLoader(); }'),
            'success' => 'function(html){ $("#globalModal").html(html); }',
            'url' => Url::to(['/user/auth/login']),
        ],
        'htmlOptions' => [
            'class' => 'btn btn-primary', 'id' => 'registerBtn'
        ]
    ]);
    ?>

<?php ActiveForm::end(); ?>

rules:

public function rules()
{
    return [
        [['email'], 'required'],
        [['email'], 'unique'],
        [['email'], 'email'],
        [['email'], 'unique', 'targetClass' => \humhub\modules\user\models\User::className(), 'message' => Yii::t('UserModule.base', 'E-Mail is already in use! - Try forgot password.')],
        [['check'], 'required'],
        [['check'], 'compare', 'compareValue' => 1, 'message'=>'bla-bla-bla'],
    ];
}

How do I do my form valid only if both 'email' is not empty an valid and 'check' is checked? Now the issue is 'check' does not validate. Thanks.

Remove the compare rule and update the required rule as shown below.

[['check'], 'required', 'requiredValue' => 1, 'message'=>'bla-bla-bla'],

Try the following:

Add this method in your model:

public function validateCheckWithEmail($attribute, $params) 
{
    if (empty($this->check) && !empty($this->email) && $this->validateAttribute($this, 'email')) {
        $this->addError($attribute, $this->getAttributeLabel($attribute).' field cannon be empty.');
    }
}

In your rules add:

[['check'], 'validateCheckWithEmail', 'skipOnEmpty' => false, 'skipOnError' => false],
