+ | <code php> | ||
+ | public function store(Request $request){ | ||
+ | $validateData = $request-> | ||
+ | ' | ||
+ | ' | ||
+ | ' | ||
+ | ]); | ||
+ | // anything from here on will only be executed if the above validation was successful | ||
+ | } | ||
+ | </ | ||
+ | there are many [[https:// | ||
+ | |||
+ | now here are a few cool things about the validator: | ||

+ | * in addition to bringing the user back to the form, laravel will provide an '' | ||
+ | * even better, there is a '' | ||
+ | |||
+ | here's an example part of a blade with a form that will show some info if the validation fails: | ||
+ | |||
+ | <code html> | ||
+ | @if ($errors-> | ||
+ | <div class=" | ||
+ | You did not fill in all the form fields correctly, please correct or complete the Information given below | ||
+ | </ | ||
+ | @endif | ||
+ | <form action=" | ||
+ | @csrf | ||
+ | <div class=" | ||
+ | <div class=" | ||
+ | <label for=" | ||
+ | <input type=" | ||
+ | <div class=" | ||
+ | </ | ||
