из моего ниже кода я пытаюсь загрузить 4 изображения, но я могу только загрузить последнее изображение в папку для upload .
Моя проверка изображения и все остальные задачи работают нормально. Но только у меня проблема с несколькими изображениями для загрузки в папку отличия.
Пожалуйста, проверьте мой код ниже и помогите решить мою проблему.
