Types of Form Validation
- Client-side validation: JavaScript is typically used to validate forms on the user’s browser before submission. This provides immediate feedback to users and prevents unnecessary server requests.
- Server-side validation: Even with client-side validation, it’s crucial to re-validate form data on the server-side. This reduce any potential issues that might arise due to disabled JavaScript or browser manipulation.
