**Codeconia Presents: Laravel 11 Form Validation Example Tutorial**

Are you a Laravel developer looking to master form validation in Laravel 11? Look no further! In this tutorial, we will provide you with a step-by-step guide on how to implement form validation in Laravel 11 using practical examples and code snippets.

**Introduction to Form Validation in Laravel 11**

Form validation is a crucial aspect of web development to ensure that the data submitted by users is accurate and meets specific criteria. Laravel 11 provides a robust validation system that simplifies the process of validating input data from forms.

**Setting Up Laravel 11 Project**

Before we delve into form validation, let’s first set up a new Laravel 11 project. If you haven’t installed Laravel on your system, you can do so using Composer by running the following command:

bash
composer create-project laravel/laravel project-name "11.*"

Next, navigate to your project directory and start the Laravel development server:

bash
php artisan serve

**Creating a Form in Laravel 11**

For the purpose of this tutorial, let’s create a simple registration form that collects a user’s name, email, and password. To create the form, you can add the following code to your `resources/views/register.blade.php` file:

html
<form action="/register" method="POST">
    @csrf
    <input type="text" name="name" placeholder="Name">
    <input type="email" name="email" placeholder="Email">
    <input type="password" name="password" placeholder="Password">
    <button type="submit">Register</button>
</form>

**Implementing Form Validation in Laravel 11**

Now, let’s implement form validation for our registration form. In your `app\Http\Controllers\UserController.php` file, add the following code:

php
public function register(Request $request)
{
    $request->validate([
        'name' => 'required|string',
        'email' => 'required|email|unique:users,email',
        'password' => 'required|min:6',
    ]);

    // Logic to store user data in the database
}

In the code snippet above, we use the `validate` method to define the validation rules for each input field. In this case, we are validating that the name is required and a string, the email is required, in a valid email format, and unique in the `users` table, and the password is required and has a minimum length of 6 characters.

**Displaying Validation Errors in Laravel 11**

To display validation errors in your view, you can add the following code snippet below the corresponding form fields in your `register.blade.php` file:

html
@if ($errors->any())
    <ul>
        @foreach ($errors->all() as $error)
            <li>{{ $error }}</li>
        @endforeach
    </ul>
@endif

This code will loop through all validation errors and display them as a list on the page if there are any errors.

**Conclusion**

In this tutorial, we covered the basics of form validation in Laravel 11 and demonstrated how to implement form validation for a registration form. Laravel’s built-in validation system makes it easy to ensure the data submitted by users is accurate and meets specific criteria. We hope this tutorial has been helpful in enhancing your Laravel development skills.
