39 minutes

Course description

Validation is necessary to secure input from both users and third-parties. In this course, we’ll discuss what things to validate, why to validate them and how to use Laravel’s built-in rules to get the most secure validation configuration. We'll examine using form requests to validate for controllers, as well as using inline-validation for commands. Finally, custom validation is also built and dissected.
