Validator Example

31.1k

Validators are used to prevent SQL Injection attacks in which malicious users can enter their own SQL commands into the application through a URL parameter and execute them on behalf of other users.

Validation can be divided into three categories:

  • 1. Prospective Validation is the first step in the validation process.
  • 2. Concurrent Validation is the second step in the validation process.
  • 3. Retrospective Validation is the third step in the validation process.

Validation ensures that the provided text is in the correct format (e.g., user@example.com for email) and that the text meets the requirements for a valid entry (e.g., the email address isn't already registered, or the password meets the criteria).
