السلام عليكم ورحمة الله
حياكم الله ويعطيكم العافية جميعا
لدي سؤال ضروري وأرجو منكم المساعدة الطيبة
سؤالي هو كيف أستطيع استدعاء مستخدم واحد من جدول المستخدمين Members
عن طريق تسجيل الدخول
بحيث لو قام المستخدم أو العضو بتسجيل دخوله وتطابق إيميله وكلمة المرور كما هو في الجدول يدخل لصفحته الخاصة به
ويعرض كافة بياناته من الجدول ؟
واستفساري الآخر حينما يقوم بتسجيل الخروج كيف نمنعه من العودة مرة أخرى لصفحته لأن هذه المشكلة لم تحل معي أيضاً ..
هذه هي الأكواد التي استخدمتها ولا أدري إن كان هناك خطأ معين في الكود ..
وجزاكم الله عني كل خير
