سلام دوستان
من بعد از کلی جستجو در سایتهای خارجی، کد خوبی را پیدا کردم که بدون نیاز به دیتایس از فایلها محافظت میکنه
و امکان hotlink هم داره که بر امنیتش اضافه میکنه اما متاسفانه مشکل resume شدن دانلود را نداره
اسکریپتهایی هستند که این کاررا انجام میدند اما چون هاست دانلود من امکان افزودن دیتابیس را نداره و پشتیبانی هم ساپورت نمیکنه
کد دیگه ای پیدا کردم که قابلیت resume شدن دانلود را داره
کسی میتونه به من کمک کنه که قابلیت resume در کد دوم را در کد اول اضافه بشه
کد اول
