How to Validate Array Data in Laravel Using Request Classes

#laravel #validation
  1. Create a Request Class:

As before, create a request class with your validation rules.

php artisan make:request StoreUserRequest
Enter fullscreen mode Exit fullscreen mode

Define your validation rules in the generated request class (StoreUserRequest):

<?php namespace App\Http\Requests; use Illuminate\Foundation\Http\FormRequest; class StoreUserRequest extends FormRequest { public function authorize() { return true; } public function rules() { return [ 'name' => 'required|string|max:255', 'email' => 'required|email|unique:users,email', 'password' => 'required|string|min:8', ]; } }
Enter fullscreen mode Exit fullscreen mode
  1. Validate the Array Data in the Controller:

In your controller, you can validate the array data using the validation rules from the request class and additional rules if needed.

namespace App\Http\Controllers; use App\Http\Requests\StoreUserRequest; use Illuminate\Http\Request; use Illuminate\Support\Facades\Validator; class UserController extends Controller { public function store(Request $request) { // Example array data (in real use-case, this might come from another source) $data = [ 'name' => 'John Doe', 'email' => 'john.doe@example.com', 'password' => 'secret1234', 'age' => 25, 'terms' => true, ]; // Retrieve rules from the request class $requestClass = new StoreUserRequest(); $rulesFromRequestClass = $requestClass->rules(); // Additional validation rules $additionalRules = [ 'age' => 'required|integer|min:18', 'terms' => 'accepted', ]; // Combine rules from the request class and additional rules $combinedRules = array_merge($rulesFromRequestClass, $additionalRules); // Validate the data array with the combined rules $validator = Validator::make($data, $combinedRules); if ($validator->fails()) { return response()->json(['errors' => $validator->errors()], 422); } // Use the validated data for further processing $validatedData = $validator->validated(); // Example: Create a new user $user = User::create($validatedData); return response()->json(['message' => 'User created successfully', 'user' => $user], 201); } }
Enter fullscreen mode Exit fullscreen mode
  1. Customize Validation Messages (Optional):

You can customize the validation messages in the request class as needed.

public function messages() { return [ 'name.required' => 'The name field is required.', 'email.required' => 'The email field is required.', 'email.email' => 'The email must be a valid email address.', 'password.required' => 'The password field is required.', 'age.required' => 'The age field is required.', 'terms.accepted' => 'You must accept the terms and conditions.', ]; }
Enter fullscreen mode Exit fullscreen mode

By following these steps, you can validate array data using the validation rules defined in a request class, combined with additional rules, in your Laravel controller.
