Why Validation Matters
Validation protects applications from incorrect or incomplete data. Every application should validate user input before processing it.
Basic Validation
Laravel provides simple validation methods that allow developers to define rules for required fields, emails, numbers, strings and other data types.
Form Request Validation
Form Request classes are useful when validation logic becomes complex. They keep controllers clean and make validation reusable.
Custom Validation Messages
Laravel allows developers to customize validation error messages so users can understand what needs to be corrected.
API Validation
Validation is equally important for APIs. Invalid API input should be rejected with meaningful JSON responses.
Conclusion
Strong validation improves application reliability and helps prevent invalid data from reaching business logic.
