Ok let me be clear. I gonna give you tow solutions, the first is the best and the most proper way:
1) Generate your EntityForm Type: bin/console make:form
or d:g:form
command.
2) Then just add some few lines to submit and get the errors.
public function cart_newAction(Request $request)
{
$entity = new Product();
$form = $this->createForm(EntityType::class, $entity);
$form->submitForm($request->request->all(), false);
if ($request->getMethod()->isPost())
{
if ($form->isValid()) {
echo 'Error';
}
else {
echo 'Success';
}
}
return $this->render('CartCartBundle:Cart:Add.html.twig', [
'errors' => $form->getErrors(),
]);
}
The second solution is bind your data into your entity object because we need to set the data into our object.
1) First step create a private
fonction in your current class to bind all the submited data:
private function bindEntityValues(Product $entity, array $data) {
foreach ($data as $key => $value){
$funcName = 'set'+ucwords($key);
if(method_exists($entity, $funcName)) $entity->$funcName($value);
}
}
Then your cart_newAction should be like this:
public function cart_newAction(Request $request)
{
$entity = new Product();
$this->bindEntityValues(entity, $request->request->all());
$errors= $this->get('validator')->validate($entity)
if (count($errors) > 0) {
echo 'Error';
}
else {
echo 'Success';
}
}
return $this->render('CartCartBundle:Cart:Add.html.twig', ['errors' => $errors]);
}
Wish this helped you to have a clear vision.
