yii2 load a view that content a form into modal - php

Question

I'm loading a view which is the result of a controller action:
public function actionCreate()
{
$modelCreate = new CreateForm();
$user = User::findOne(Yii::$app->user->id);
$postes = $this->postes($user);
if (Yii::$app->request->isAjax && $modelCreate->load(Yii::$app->request->post())) {
Yii::$app->response->format = Response::FORMAT_JSON;
return ActiveForm::validate($modelCreate);
}
if ($modelCreate->load(Yii::$app->request->post()) && Yii::$app->request->isPost){
$modelCreate->photo = UploadedFile::getInstance($modelCreate, 'photo');
if ($modelCreate->create()){
return $this->redirect(['site/view-accounts']);
}
}
return $this->renderAjax('create-account', ['modelCreate' => $modelCreate, 'postes' => $postes]);
}
Here's my script that loads the view:
$(function(){
$('#createModal').click(function(){
$('#newAccountModal').modal('show')
.find('#modalContentCreate')
.load($(this).attr('value'));
});
});
Here's the code of my modal:
<?php
Modal::begin([
'id' => 'newAccountModal',
'header' => '<h4>create account</h4>',
]);
?>
<div id ="modalContentCreate">
</div>
<?php Modal::end();?>
But it insert the all scripts after the form tag and then triggers an error: the xmlHttpRequest object is deprecated...
And the other script of form validation is not inserted at the end of body of main page.
How can I do trigger validation of my form and remove this error message?

Answer 1

to load content into a form, i would suggest using Pjax as the modal's content, like:
<?php
Modal::begin([
'id' => 'newAccountModal',
'header' => '<h4>create account</h4>',
]);
?>
<div id ="modalContentCreate">
<? \yii\widgets\Pjax::begin(['id' => 'pjax1', 'linkSelector' => 'a.my-pjax']) ?>
<?= $this->render('_form', ['model' => $model]) ?>
<? \yii\widgets\Pjax::end() ?>
</div>
<?php Modal::end();?>
the contained form must set the data-pjax option.
note the linkSelector for the Pjax widget. you can replace the modal's content with a link:
<?= \yii\helpers\Html::a('create account', ['account/create'], ['class' => 'my-pjax']) ?>
your controller action 'account/create' should handle your post and validation and return the
_form.php (view)
<? $form = \yii\widgets\ActiveForm::begin(['options' => ['data-pjax' => 1], 'action' => ['account/create']]) ?>
<?= $form->errorSummary($model) ?>
<?= $form->field($model, 'title') ?>
<?= \yii\helpers\Html::submitButton('Submit', ['class' => 'btn btn-primary']) ?>
<? \yii\widgets\ActiveForm::end() ?>
controller create action:
public function actionCreate()
{
$model = new \common\models\Account;
if (Yii::$app->request->isPost && $model->load(Yii::$app->request->post()) && $model->validate()) {
// $model->save()
return $this->renderAjax('_view', ['model' => $model]);
}
return $this->renderAjax('_form', ['model' => $model]);
}
