Laravel is an open-source PHP framework devised to make developing web apps easier and faster through built-in features. These features are part of what makes Laravel so widely used by web developers.
Laravel includes a wide variety of beneficial validation rules that you can apply to data, even providing the ability to validate if values are unique in a given database table. Routing in Laravel allows you to route all your application requests to their appropriate controller. In this article, I will show you some laravel validation and routing tips. Hopefully, you can use them to supercharge your Laravel applications. Here we go!
Position placeholder in the validation messages
In Laravel 9 you can use the :position placeholder in the validation messages if you're working with arrays.
This will output: "Please provide an amount for price #2"
class CreateProductRequest extends FormRequest { public function rules(): array { return [ 'title' => ['required', 'string']; 'description' => ['nullable', 'sometimes', 'string'], 'prices' => ['required', 'array'], 'prices.*.amount' => ['required', 'numeric'], 'prices.*.expired_at' => ['required', 'date'], ]; } public function messages(): array { 'prices.*.amount.required' => 'Please provide an amount for price #:position' } } New array validation rule required_array_keys
Laravel 8.82 adds a required_array_keys validation rule. The rule checks that all of the specified keys exist in an array.
Valid data that would pass the validation:
$data = [ 'baz' => [ 'foo' => 'bar', 'fee' => 'faa', 'laa' => 'lee' ], ]; $rules = [ 'baz' => [ 'array', 'required_array_keys:foo,fee,laa', ], ]; $validator = Validator::make($data, $rules); $validator->passes(); // true Invalid data that would fail the validation:
$data = [ 'baz' => [ 'foo' => 'bar', 'fee' => 'faa', ], ]; $rules = [ 'baz' => [ 'array', 'required_array_keys:foo,fee,laa', ], ]; $validator = Validator::make($data, $rules); $validator->passes(); // false Route resources grouping
If your routes have a lot of resource controllers, you can group them and call one Route::resources() instead of many single Route::resource() statements.
Route::resources([ 'photos' => PhotoController::class, 'posts' => PostController::class, ]); Custom route bindings
Did you know you can define custom route bindings in Laravel?
In this example, I need to resolve a portfolio by slug. But the slug is not unique, because multiple users can have a portfolio named Foo. So I define how Laravel should resolve them from a route parameter
class RouteServiceProvider extends ServiceProvider { public const HOME = '/dashboard'; public function boot() { Route::bind('portfolio', function (string $slug) { return Portfolio::query() ->whereBelongsto(request()->user()) ->whereSlug($slug) ->firstOrFail(); }); } } Route::get('portfolios/{portfolio}', function (Portfolio $portfolio) { /* * The $portfolio will be the result of the query defined in the RouteServiceProvider */ }) Mac validation rule
New mac_address validation rule added in Laravel 8.77
$trans = $this->getIlluminateArrayTranslator(); $validator = new Validator($trans, ['mac' => '01-23-45-67-89-ab'], ['mac' => 'mac_address']); $this->assertTrue($validator->passes()); Validate email with TLD domain required
By default, the email validation rule will accept an email without a TLD domain (ie: taylor@laravel, povilas@ldaily)
But if you want to make sure the email must have a TLD domain (ie: taylor@laravel.com, povilas@ldaily.com), use the email:filter rule.
[ 'email' => 'required|email', // before 'email' => 'required|email:filter', // after ], Route view
You can use Route::view($uri , $bladePage) to return a view directly, without having to use the controller function.
//this will return home.blade.php view Route::view('/home', 'home'); These are some useful tips and tricks related to laravel Validation & Routing.
