Suppose I have the following Entities: Pizza PizzaType = [Cheese, Meat, Vegetable, Supreme] Toppings = [Pepperoni, Sausage, Peppers, Mushrooms]
When I create a pizza and set its type to Meat I want to be able to validate that only a "meat" type of topping is chosen, same with Vegetable, while supreme will allow any topping (meat or vegetable)... Assume there is already a property for each topping that maps to a pizza type. Really just interested in know what type of validator to use...
You can pass a callback to validation_groups
option in your form for the desired field. Callback will have access to submitted data like this
... 'validation_groups' => static function (FormInterface $form) {
$data = $form->getData();
// your logic to determine validation groups
}
in there you can check what has been submitted and return an array of validation groups, different for each type of entity you want.
