Yii2: 'Save Draft' button - validation

Question

I'd like to have a form with the three buttons:
OK button: It runs validation and post data on success.
Cancel button: Skip validation and posting and redirect to the other view.
Save Draft button: Post data without validation.
I know how to implement OK and Cancel buttons, but how to prevent the validation on 'Save Draft' button click?

Answer 1

To bypass the client-end validation just for the draft button, what i would suggest is not to use the submit button for the Draft , use normal button and save the draft using ajax call , this would trigger the validation if you are typing into the field or blur out but not if you hit the draft button. use $.serialize() to get the form inputs and send call to save as draft.

Answer 2

Hope it will help for someone.
Here is the solution:
Add 'Draft Button' as a normal button in your view:
<?= Html::button('Save Draft', ['class' => 'btn btn-default btn-block', 'id' => 'save-draft-btn']) ?>
Add JS file to your view and specify onClick event for the button:
$('#save-draft-btn').on('click', function (e) {
$.ajax({
type: 'POST',
url: draftUrl,
data: $('#report-index').serialize()
});
});
Add the action to your controller:
public function actionSaveDraft($idSupply)
{
//load models like this
$report = \app\models\Reports::findOne($idSupply);
//fill with the POST data
$report->load(Yii::$app->request->post());
//save without validation
$report->save(false);
//inform the user on success saving
Yii::$app->session->setFlash('success', 'Draft Saved');
//redirect to the editing page
return $this->redirect(['index', 'idSupply' => $report->id_supply]);
}
