Why is yii2 validation not working?

Question

Yii

Good day! There is a form for adding information to the site. To be more precise, there are three of them similar (slightly different fields). Two forms work out validation perfectly, and the third does not respond.
Here is the third form code:
(_form.php)

<?php $form = ActiveForm::begin(['options' => ['enctype' => 'multipart/form-data']]) ?>
<div class="row">
    <div class="col-sm-6">
        <?= $form->field($model, 'type_of_sales')->dropDownList(['0' => 'Продать', '1' => 'Аренда', '2' => 'Долгосрочная аренда',]) ?>
        <?= $form->field($model, 'description')->textarea(['rows' => 6]) ?>
        <?= $form->field($model, 'area')->textInput(['maxlength' => true]) ?>
        <?= $form->field($model, 'city')->dropDownList($city) ?>
        <?= $form->field($model, 'district')->dropDownList(\yii\helpers\ArrayHelper::map(\app\modules\admin\models\Districts::find()->all(), 'title', 'title')) ?>
        <?= $form->field($model, 'address')->textInput(['maxlength' => true]) ?>
        <?= $form->field($model, 'land_type')->dropDownList($land_type) ?>
    </div>
    <div class="col-sm-6">
        <?= $form->field($model, 'phone')->textInput(['maxlength' => true]) ?>
        <?= $form->field($model, 'communicationArr')->checkboxList(['Свет' => 'Свет', 'Газ' => 'Газ', 'Вода' => 'Вода']) ?>
        <?= $form->field($model, 'contact_name')->textInput(['maxlength' => true]) ?>
        <?= $form->field($model, 'vip')->radioList(['0' => 'Нет', '1' => 'Да',]) ?>
        <div class="exchange_trigger">
            <?= $form->field($model, 'exchange')->radioList(['1' => 'Да', '0' => 'Нет',]) ?>
        </div>
        <?= $form->field($model, 'exchange_field', ['options' => ['id' => 'rent_block']])->textInput(['maxlength' => true, 'placeholder' => 'Например: гараж, дачу, 2-х комнатную квартиру',])->label(false) ?>
        <?= $form->field($model, 'price', ['options' => ['class' => 'col-sm-8 row', 'id' => 'price_block']])->textInput(['maxlength' => true]) ?>
        <?= $form->field($model, 'currency', ['options' => ['class' => 'col-sm-4 row pull-right', 'id' => 'currency_block']])->dropDownList(['uah' => 'UAH', 'usd' => 'USD', 'eur' => 'EUR']) ?>
        <div class="col-sm-12">
            <?= $form->field($model, 'gallery[]', ['options' => ['class' => 'row']])->fileInput(['multiple' => true]) ?>
        </div>
    </div>
    <div class="col-sm-12">
        <div class="form-group col-sm-6">
            <?= $form->field($model, 'reCaptcha')->widget(
                \himiklab\yii2\recaptcha\ReCaptcha::className(),
                ['siteKey' => 'бла-бла-бла']
            )->label(false)?>
        </div>
        <div class="col-sm-6">
            <?= Html::submitButton($model->isNewRecord ? 'Добавить!' : 'Обновить', ['class' => $model->isNewRecord ? 'btn btn-success center-block' : 'btn btn-primary center-block']) ?>
        </div>
    </div>
</div>
<?php ActiveForm::end(); ?>

}

This is a standard yii2 validation when you click on a field and then reset the focus, and it highlights the field in red or green for you. Tell me, what could it be? Thanks in advance!

Answer 1

the problem is in your scenarios method, there is one active attribute specified for the default scenario. Accordingly, all other attributes are not active, and therefore are not validated on the client.

Answer 2

If the forms are identical, there may be a jamb in js on the page, therefore events and validation do not work

Answer 3

Too little information. Bring your code from the rules() method, where you set the validation rules, as well as a code fragment, where you display the field in the template
