Yii2 Basic Clear input form after submit button - forms

Question

I created a modal to create post and another one to create gallery inside another view and it work perfect but after I click submit my form keeps the data entered even if I refresh the page it's still have the data entered, is it possible to clear form after submit
My view code of post is :
<?php
use yii\helpers\Html;
use yii\widgets\ActiveForm;
/* #var $this yii\web\View */
/* #var $ly_addPost app\models\Posts */
/* #var $form yii\widgets\ActiveForm */
?>
<div class="posts-form">
<?php $form = ActiveForm::begin(); ?>
<?= $form->field($ly_addPost, 'Post_title')->textInput(['maxlength' => true]) ?>
<?= $form->field($ly_addPost, 'Post_text')->textarea(['rows' => 6]) ?>
<?= $form->field($ly_addPost, 'Post_file')->textInput(['maxlength' => true]) ?>
<?= $form->field($ly_addPost, 'Permission_id')->dropdownList([$ly_addPost->Permission_id]);?>
<div class="form-group">
<?= Html::submitButton('Create' , ['class' => 'btn btn-primary']) ?>
</div>
<?php ActiveForm::end(); ?>
</div>
My controller has two create from from two different view one for post and another one for gallery
my controller code is :
public function actionView($id)
{
$ly_addPost = new Posts();
$ly_addGallery = new Galleries();
//$ly_addAudio = new Audios();
//$ly_addVideo = new Videos();
$ly_addPost->Channel_id = $id;
$ly_addGallery->Channel_id = $id;
$ly_addPost->Userid = Yii::$app->user->id;
$ly_addGallery->Userid = Yii::$app->user->id;
// for permission post
$ly_addPost->Permission_id = Permission::find()
->select(['Permission_type'])
->indexBy('Permission_id')
->column();
// for permission galery
$ly_addGallery->Permission_id = Permission::find()
->select(['Permission_type'])
->indexBy('Permission_id')
->column();
if ($ly_addPost->load(Yii::$app->request->post()) ) {
$ly_addPost->Post_id = Yii::$app->params['ly_randCttid'];
$ly_addPost->Post_uid = Yii::$app->params['ly_randCttid'];
$ly_addPost->save();
return $this->render('view', [
'model' => $this->findModel($id),
'ly_addPost' => $ly_addPost,
'ly_addGallery' => $ly_addGallery,
]);
exit();
}
else if ($ly_addGallery->load(Yii::$app->request->post()) ) {
$ly_addGallery_id = Yii::$app->params['ly_randCttid'];
$ly_addGallery_uid = Yii::$app->params['ly_randCttid'];
$ly_addGallery->save();
return $this->render('view', [
'model' => $this->findModel($id),
'ly_addPost' => $ly_addPost,
'ly_addGallery' => $ly_addGallery,
]);
exit();
} else {
return $this->render('view', [
'model' => $this->findModel($id),
'ly_addPost' => $ly_addPost,
'ly_addGallery' => $ly_addGallery,
]);
}
}

Answer 1

you have to clear $ly_addPost before rendering
} else {
foreach ($ly_addPost as $key => $value) {
$ly_addPost->$key = null; //set to null instead of unsetting
} // this foreach clear all variable of $ly_addPost;
return $this->render('view', [
'model' => $this->findModel($id),
'ly_addPost' => $ly_addPost,
'ly_addGallery' => $ly_addGallery,
]);
}

Answer 2

I fixed by changing
return $this->render('view', [
'model' => $this->findModel($id),
'ly_addPost' => $ly_addPost,
'ly_addGallery' => $ly_addGallery,
]);
exit();
To
return $this->refresh();
Now my code in controller is
if ($ly_addPost->load(Yii::$app->request->post()) ) {
$ly_addPost->Post_id = Yii::$app->params['ly_randCttid'];
$ly_addPost->Post_uid = Yii::$app->params['ly_randCttid'];
$ly_addPost->save();
return $this->refresh();
}
