Validation 376
.
1 php artisan make:request StoreBlogPostRequest
The generated class will be placed in the app/Http/Requests directory. Let’s add a few validation
rules to the rules method:
.
1 /**
2 * Get the validation rules that apply to the request.
3 *
4 * @return array
5 */
6 public function rules()
7 {
8 return [
9 'title' => 'required|unique:posts|max:255',
10 'body' => 'required',
11 ];
12 }
So, how are the validation rules evaluated? All you need to do is type-hint the request on your
controller method. The incoming form request is validated before the controller method is called,
meaning you do not need to clutter your controller with any validation logic:
.
1 /**
2 * Store the incoming blog post.
3 *
4 * @param StoreBlogPostRequest $request
5 * @return Response
6 */
7 public function store(StoreBlogPostRequest $request)
8 {
9 // The incoming request is valid...
10 }
If validation fails, a redirect response will be generated to send the user back to their previous
location. The errors will also be flashed to the session so they are available for display. If the request
was an AJAX request, a HTTP response with a 422 status code will be returned to the user including
a JSON representation of the validation errors.
