Ajax validation with custom id in yii2 - ajax

Question

I have a same field in foreach loop like below
foreach ( $subCategoryData as $k => $val) {
<?= $form->field($model, 'sub_category', ['template' => '{input}'])->textInput(['maxlength' => 255, 'class' => 'form-control required section_name', 'name' => "Category[sub_category][$k][name]"]) ?>
} ?>
I have ajax validation with custom method it is working fine.
But it is Working with only first input. Because it has same ID.
But when I changed it with 'inputOptions' => ['id' => 'myCustomId'] and make it unique with below and my ajax validation is not called.
foreach ( $subCategoryData as $k => $val) {
<?= $form->field($model, 'sub_category', ['template' => '{input}','inputOptions' => ['id' => "category-sub_category_".$k]])->textInput(['maxlength' => 255, 'class' => 'form-control required section_name', 'name' => "Category[sub_category][$k][name]"]) ?>
}

Your question is different from the posts you introduced.
You should use loadMultiple.
Example:
if (\Yii::$app->request->isAjax) {
if (\yii\base\Model::loadMultiple($model,\Yii::$app->request->post())) {
\Yii::$app->response->format = Response::FORMAT_JSON;
echo json_encode(ActiveForm::validateMultiple($model));
\Yii::$app->end();
}
}
if ( \yii\base\Model::loadMultiple($model, Yii::$app->request->post()) && \yii\base\Model::validateMultiple($model)) {
foreach ($model as $models) {
$models->save(false);
}
in view:
<?php $form = ActiveForm::begin([
'enableAjaxValidation' => true,
]);
