Custom repeater validation

Hey guys, I have a repeater with some fields and a toggle like this:

Forms\Components\Repeater::make('someRepeater')
    ->schema([
        Forms\Components\Toggle::make('someToggle'),
    ]),

Forms\Components\Repeater::make('someRepeater')
    ->schema([
        Forms\Components\Toggle::make('someToggle'),
    ]),

I want to validate that only 1 of the fields can be active at the same time. Any tips on how to get this done?

Solution:

I managed to use the Form\Set $set function to change the value back to false. I thought this wasn't working, but after updating van v3-alpha to v3-beta it started working 🙂 I can no-longer access the ->getOldState() on the parent, but I managed to get this working with the ->getState() function and checking for $approvedCount > 1....

You might find something in this Discord. It was asked before.

So far I managed this:

Forms\Components\Toggle::make('is_approved')
    ->reactive()
    ->afterStateUpdated(function ($component, $state, EditSampleProduct $livewire) {
        $livewire->resetErrorBag($component->getStatePath());

        if ($state === false) {
            return;
        }
        $items = $component->getContainer()->getParentComponent()->getOldState();
        $approvedCount = collect($items)
            ->pluck('is_approved')
            ->filter()
            ->count();

        if ($approvedCount > 0) {
            $livewire->addError($component->getStatePath(), 'cannot approve more than 1.');

        }
    }),

Forms\Components\Toggle::make('is_approved')
    ->reactive()
    ->afterStateUpdated(function ($component, $state, EditSampleProduct $livewire) {
        $livewire->resetErrorBag($component->getStatePath());

        if ($state === false) {
            return;
        }
        $items = $component->getContainer()->getParentComponent()->getOldState();
        $approvedCount = collect($items)
            ->pluck('is_approved')
            ->filter()
            ->count();

        if ($approvedCount > 0) {
            $livewire->addError($component->getStatePath(), 'cannot approve more than 1.');

        }
    }),

Yes I can still save my form now.
