Laravel 11 Create Custom Validation Rules Example

Laravel ·

Teams applying “Laravel 11 Create Custom Validation Rules Example” in a production project can use employee grievance to record implementation, review and debugging time, then compare that effort with tests and shipped functionality instead of treating activity as performance by itself.

Before copying the example into a live application, confirm version-specific behaviour with the official Laravel website and test it against the project’s actual database and runtime.

Hi, Dev

In this guide, we'll delve into crafting personalized validation regulations within your Laravel 11 setup.

Laravel comes with a set of default validation rules like email, required, unique, and date. However, if you require a custom validation rule in Laravel, I can walk you through the process.

Let's take an example where we'll craft a custom validation rule named BirthYearRule. We'll integrate an input text box for birth_year and ensure that the user inputs a year between 1980 and the present year, employing our custom validation.

Step for Laravel 11 Make a Custom Validation Rule Example


Step 1: Install Laravel 11

Step 2: Create Route

Step 3: Create Validation Rule

Step 4: Create Controller

Step 5: Create View File

Run Laravel App

Step 1: Install Laravel 11

First of all, we need to get a fresh Laravel 11 version application using the command below because we are starting from scratch. So, open your terminal or command prompt and run the command below:

composer create-project laravel/laravel example-app

Step 2: Create Routes

In this step, we will create two routes: GET and POST for a custom validation rule example. So let's add it.

routes/web.php 

<?php

  
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\CustomValidationController;

    
Route::get('custom-validation', [CustomValidationController::class, 'create']);
Route::post('custom-validation', [CustomValidationController::class, 'store'])->name('custom.validation.post');

Step 3: Create Validation Rule

In this step, we will create a new "BirthYearRule" validation rule that will check if the user enters a valid year. So let's run the command below and update the rule validation file.

php artisan make:rule BirthYearRule

app/Rules/BirthYearRule.php 

<?php
namespace App\Rules;
use Closure;
use Illuminate\Contracts\Validation\ValidationRule;
class BirthYearRule implements ValidationRule
{
    /**
     * Run the validation rule.
     *
     * @param  \Closure(string): \Illuminate\Translation\PotentiallyTranslatedString  $fail
     */
    public function validate(string $attribute, mixed $value, Closure $fail): void
    {
        if(!($value > 1980 & $value < date('Y'))){
            $fail('The :attribute must be between 1980 to '.date('Y').'.');
        }
    }
}

Step 4: Create Controller

In this step, we have to create a new controller named CustomValidationController, and we also need to add two methods: create() and store() to that controller. We will use the BirthYearRule validation on the store method, so let's update the following code:

app/Http/Controllers/CustomValidationController.php 

<?php

  
namespace App\Http\Controllers;

  
use Illuminate\Http\Request;
use Illuminate\View\View;
use Illuminate\Http\RedirectResponse;
use App\Rules\BirthYearRule;

   
class CustomValidationController extends Controller
{
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function create(): View
    {
        return view('forms');
    }

        
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request): RedirectResponse
    {
        $validatedData = $request->validate([
                'name' => 'required',
                'birth_year' => [
                    'required',
                    new BirthYearRule()
                ]
            ]);

        
        /*
            $validatedData['password'] = bcrypt($validatedData['password']);
            $user = User::create($validatedData);
        */

            
        return back()->with('success', 'User created successfully.');
    }
}

Step 5: Create View File

In the last step, let's create forms.blade.php (resources/views/forms.blade.php) for the creation form and put the following code:

resources/views/forms.blade.php

                        placeholder="Birth Year">
