Validation
التحقق من البيانات
GLS-000080
Definition
Checking that data is correct, complete, and safe before using it or saving it.
التحقق من أن البيانات صحيحة وكاملة وآمنة قبل استخدامها أو حفظها.
Why It Matters
Never trust user input. Without server-side validation, a malicious user could send corrupt or dangerous data directly to your API or database.
لا تثق أبدًا بمدخلات المستخدم. بدون التحقق من جانب الخادم، يمكن للمستخدم الضار إرسال بيانات فاسدة أو خطيرة مباشرةً إلى API أو قاعدة البيانات.
