Access Relationship Input in mutateFormDataBeforeCreate()

Hello, I want to access the relationship inputs in the

mutateFormDataBeforeCreate()

mutateFormDataBeforeCreate()

mutateFormDataBeforeCreate()

mutateFormDataBeforeCreate() method, but I can only access the non-relationship inputs. How to do that?

protected function mutateFormDataBeforeCreate(array $data): array
{
  $data['cashier_id'] = auth()->id();
  return $data;
}

protected function mutateFormDataBeforeCreate(array $data): array
{
  $data['cashier_id'] = auth()->id();
  return $data;
}

protected function mutateFormDataBeforeCreate(array $data): array
{
  $data['cashier_id'] = auth()->id();
  return $data;
}

protected function mutateFormDataBeforeCreate(array $data): array
{
  $data['cashier_id'] = auth()->id();
  return $data;
}

// Data Result
[
  "discount" => 10 // from TextInput
  "cashier_id" => "01ha16anrawwd9pknhfy3g43yx"
]

// Data Result
[
  "discount" => 10 // from TextInput
  "cashier_id" => "01ha16anrawwd9pknhfy3g43yx"
]

// Data Result
[
  "discount" => 10 // from TextInput
  "cashier_id" => "01ha16anrawwd9pknhfy3g43yx"
]

// Data Result
[
  "discount" => 10 // from TextInput
  "cashier_id" => "01ha16anrawwd9pknhfy3g43yx"
]

Solution

Try

dd($this->data)

dd($this->data)

dd($this->data)

dd($this->data), see if the input you want is there
