Access any field from form with anonymous action

Hello everybody, I have an anonymous function right in the middle of a form, I want to access my "quantity" field from the action() method of my anonymous function.

TextInput::make('quantity')
  ->label(__('fields.quantity'))
  ->numeric()
  ->step(0.1),

Actions::make([
  Action::make('test')
    ->action(function(Get $get, Set $set, Livewire $livewire) {

        // Need to get the value of the step of Quantity field
        // Something like this : $livewire->component('quantity')->getStep();
        // But doesnt work
        
        // Some code...

    }),
])

TextInput::make('quantity')
  ->label(__('fields.quantity'))
  ->numeric()
  ->step(0.1),

Actions::make([
  Action::make('test')
    ->action(function(Get $get, Set $set, Livewire $livewire) {

        // Need to get the value of the step of Quantity field
        // Something like this : $livewire->component('quantity')->getStep();
        // But doesnt work
        
        // Some code...

    }),
])

How to do ? I didn't find much choice in the documentation or on the internet... Thank's

Solution:

```php ->action(function (\Filament\Forms\Components\Component $component) { $container = $component->getContainer()->getParentComponent()->getContainer(); $quantity = $container->getComponent('data.quantity'); //$quantity->getStep()...

$get('quantity') ?

This method only retrieves the value of my field. And this is the only interaction we can have with anonymous form functions. I am looking to be able to modify the appearance or retrieve information from my field. For example, I'm looking to access my field so I can make it disabled once I click my anonymous action button. I know that there is this kind of method but I cannot access my component as it is not linked to my action. It's impossible for me to do anything.

->afterStateUpdated(fn (Select $component) => $component
  ->getContainer()
  ->getComponent('dynamicTypeFields')
  ->getName())

->afterStateUpdated(fn (Select $component) => $component
  ->getContainer()
  ->getComponent('dynamicTypeFields')
  ->getName())

Or maybe there is a method to attach an anonymous action to a component? https://filamentphp.com/docs/3.x/forms/actions#adding-anonymous-actions-to-a-form-without-attaching-them-to-a-component

->action(function (\Filament\Forms\Components\Component $component) {
    $container = $component->getContainer()->getParentComponent()->getContainer();
    $quantity = $container->getComponent('data.quantity');
    //$quantity->getStep()
})

->action(function (\Filament\Forms\Components\Component $component) {
    $container = $component->getContainer()->getParentComponent()->getContainer();
    $quantity = $container->getComponent('data.quantity');
    //$quantity->getStep()
})
