Ajax Bundle Laravel Package

Auto-refresh a form

You can automatically send an ajax request to update your form when an input/select change, just add the data attribute "data-refreshonchange":

    <select name="category" data-refreshonchange="true">
        <option value="transport">Transport</option>
        <option value="structure">Stucture</option>
    </select>

Then in your controller's action:

 if ($request->query->get('novalidate', false) === false) {
    if ($form->isValid()) {
        // form is valid
    } else {
        // avoid to display errors when novalidate
        $form = $formFactory->createForm();
        $form->setData($user);
    }
}

For some reason, you would not refresh some parts of your form (for example an input type="file"). Then, add the data attribute 'data-ignoreonchange="$some_unique_id"'.
