I’ve got the TransactionRequest which handles the validation of an Transaction. There are few simple rules, but also some complicated Rules I’ve created.
Now I am making an action of adding (confirming) multiple transactions in one request – ConfirmTransactionsRequest. It consists of “transactions” array, which I validate by “array” and “min:1” rules, however I want to validate every row using the request I mentioned about. There is a lot of logic in the TransactionRequest and I don’t want to duplicate it.

Is there a way to use the TransactionRequest in the ConfirmTransactionsRequest? I’ve tried to create request instance inside foreach loop, but it’s not working. Here’s my current code:

class TransactionRequest extends FormRequest
{
    private $rules = [];
    private $baseRules = [
      'amount' => ['required', 'numeric', 'min:0.01'],
      'date' => ['required', 'date'],
      'note' => ['sometimes', 'max:100']
    ];

    // I can get the simple rules by executing this method, but it don't see request input
    public function rules(): array
    {
      $transaction = $this->transactionsR()->findOne($this->input('id'));
      $selectedLoan = $this->loansR()->findOne($this->input('loan_id'));
      (...)
     }
}

class ConfirmTransactionsRequest extends FormRequest
{
    public function rules()
    {
        // Not working
        foreach ($this->input('transactions') as $row) {
            $transactionRequest = new TransactionRequest([], $row);
            $transactionRequest->validated(); // "Call to a member function validated() on null"
        }

        $rules = $this->prepareTransactionRequestValidationToApplyToEveryRow($transactionRequest->rules());

        $rules['planned_transactions'] = ['required', 'array', 'min:1'];

        return $rules;
    }
}
