عدم تكرار الاسم - yossefsaad370 - 02-11-23
مرحباً بالجميع، هذا الموقع يبيع الوجبات للطلاب. ويشترط على الطالب إبراز بطاقته الجامعية أو بطاقة الهوية لشراء الوجبة. أريد من الطالب ألا يشتري الوجبة بشكل متكرر لأنه لديه البطاقة الجامعية وبطاقة الهوية والرقمين مختلفين. أريد البحث بالاسم إذا كان الاسم موجود في قاعدة البيانات وقت الوجبة فلن يتكرر إذا كان مع الرقم الجامعي أو رقم الهوية
هذا الكود .......
