What are some effective data validation techniques in Laravel?

In Laravel, you can use built-in validation rules, custom validation rules, and form request validation. Would you like to know more about any specific technique?

Can you explain how to create custom validation rules?

Sure! You can create a custom validation rule by using the make:rule Artisan command. This generates a new rule class where you can define your validation logic.

How do I apply these validation rules to a form request?

You can apply validation rules in a form request by overriding the rules method in your request class. Just return an array of rules for each field.

What happens if validation fails?

If validation fails, Laravel automatically redirects the user back to the previous page with error messages and old input data.
