Bypass required when save as draft

Imagine you have a massive form with two buttons: Save as Draft and Submit, where all fields or a lot of them are required to submit.

You may want to let users save the form as draft even if it's incomplete.

Here's what you could do:

 1public function saveDraft()
 2{
 3    foreach ($this->form->getComponents() as $component) {
 4        $this->unrequireFields(component: $component);
 5    }
 6    $state = $this->form->getState();
 7    //...
 8}
 9
10protected function unrequireFields($component, array $except = []): void
11{
12    if ($component instanceof Field) {
13        if (!in_array($component->getName(), $except)) {
14            if ($component->isRequired()) {
15                $component->markAsRequired();
16            }
17            $component->required(false);
18        }
19        return;
20    }
21
22    foreach ($component->getChildComponents() as $child) {
23        $this->unrequireFields($child, $except);
24    }
25}

Here, the unrequireFields method recursively remove the required for all the fields.

It also mark them as required thanks to the markAsRequired method in order to have the red asterisk even if the fields are not really required.
