model-form currently has two methods for receiving callback functions:
// callback before save
$form->saving(function (Form $form) {
//...
});
// callback after save
$form->saved(function (Form $form) {
//...
});The form data that is currently submitted can be retrieved from the callback parameter $form:
$form->saving(function (Form $form) {
dump($form->username);
});Can redirect other urls by returning an instance of Symfony\Component\HttpFoundation\Response directly in the callback:
$form->saving(function (Form $form) {
// returns a simple response
return response('xxxx');
});
$form->saving(function (Form $form) {
// redirect url
return redirect('/admin/users');
});
$form->saving(function (Form $form) {
// throws an exception
throw new \Exception('Error friends. . .');
});Return error or success information on the page:
use Illuminate\Support\MessageBag;
// redirect back with an error message
$form->saving(function ($form) {
$error = new MessageBag([
'title' => 'title...',
'message' => 'message....',
]);
return back()->with(compact('error'));
});
// redirect back with a successful message
$form->saving(function ($form) {
$success = new MessageBag([
'title' => 'title...',
'message' => 'message....',
]);
return back()->with(compact('success'));
});
