Я работаю над формой сбора продаж, в которой sale_quantity , введенное , не должно превышать stock_quantity в DB . Когда я использую идею в: Laravel проверяет динамически добавленный ввод с пользовательскими сообщениями , есть один ответ с:
'orderQty.*' => 'required|numeric|min:1|max:'.$product['productQty']
Я сделал это, как вы увидите в моей функции store и обновление функции в SalesController.php, ошибка не возникает , но форма отказывается отправлять и показывает это какфлэш-сообщение:
Объем продажи не может превышать '. $ stocks [' stock_quantity '].
Это не означает, что он показывает, потому что их значение stock_quanity в базе данных больше.
