Yii2 use form tags - forms

Question

When I submit my form i got some errors,
This is my form script which contains posted fields.
<?php $form = ActiveForm::begin([
'action'=>'userpermission/create',
]); ?>
<form method="post" action="<?php echo Yii::$app->getUrlManager()->createUrl('admin/userpermission/create')?>">
<ul class="list-unstyled">
<li>
<?= $form->field($model, 'idPermission')->checkboxList(ArrayHelper::map(Permission::find()->all(),"idPermission", "libelle", [
'onclick' => "$(this).val( $('input:checkbox:checked').val());",
'item' => function($index, $label, $name, $checked, $value) {
return "<label class='ckbox ckbox-primary col-md-4'><input type='checkbox' {$checked} name='{$name}' value='{$value}' tabindex='3'>{$label}</label>";
}
])) ?>
</li><br>
</ul>
<div class="form-group">
<?php Html::submitButton($model->isNewRecord ? 'Valider' : 'Create' ,['class' => $model->isNewRecord ? 'btn btn-primary','value'=>'Create', 'name'=>'submit']) ?>
</div>
<?php ActiveForm::end(); ?>
and my create function looks like but i got the error undefined variable model!
public function actionCreate()
{
$model = new Userpermission();
if ($model->load(Yii::$app->request->post()) && $model->save()) {
print_r(Yii::$app->request->post());
exit;
return $this->redirect(['index', 'id' => $model->id]);
} else {
return $this->render('create', [
'model' => $model,
]);
}
}

1st off, you dont need that <form> tag.
<?php $form = ActiveForm::begin([
'action'=>'userpermission/create',
]); ?>
creates and initializes the form for you with corresponding client-validations.
the possible issue is due to unclosed </form> which anyways is unnecessary.
suggesting to remove the <form> tag entirely. and try again and if any issue please let me know the error.
also bring the print_r(Yii::$app->request->post()); before if condition.
enable error reporting in your function
error_reporting(E_ALL);
please give the filename to code block. it would be easier to understand that way.
