As a website owner, you might want to protect your website from bots and spam. One of the ways to achieve this is by using a captcha. In this tutorial, we will learn how to create a captcha in Laravel.
Step 1: Install Laravel
To get started, you need to install Laravel. You can install Laravel by using the composer. Open your terminal and type the following command:
composer create-project --prefer-dist laravel/laravel captcha
This will create a new Laravel project named "captcha".
Step 2: Install the Captcha Package
Next, we need to install the "mews/captcha" package. This package provides an easy-to-use captcha generator. Open your terminal and type the following command:
composer require mews/captcha
Step 3: Configure the Captcha Package
After installing the package, we need to configure it in our Laravel application. Open your config/app.php file and add the following lines to the providers array:
Mews\Captcha\CaptchaServiceProvider::class,
Next, add the following lines to the aliases array:
'Captcha' => Mews\Captcha\Facades\Captcha::class,
Step 4: Create a Captcha Route
Next, we need to create a captcha route in our Laravel application. Open your routes/web.php file and add the following route:
Route::get('/captcha', function () {
return Captcha::create();
});
Step 5: Display the Captcha Image
Finally, we need to display the captcha image on our web page. Open your resources/views/welcome.blade.php file and add the following code:
<img src="{{ url('/captcha') }}" alt="captcha">
This code will display the captcha image on your web page.
Step 6: Validate the Captcha
To validate the captcha, we need to add some server-side code. Open your app/Http/Controllers/ContactController.php file and add the following code:
<?php
use Illuminate\Http\Request;
use Mews\Captcha\Captcha;
public function contact(Request $request, Captcha $captcha)
{
$this->validate($request, [
'captcha' => 'required|captcha'
]);
// Your code here
}
This code will validate the captcha on the server-side.
Step 7: Customize the Captcha
You can customize the captcha by modifying the configuration file. Open your config/captcha.php file and modify the configuration options as per your requirements.
That's it! You have successfully created a captcha in Laravel. Captchas can help protect your website from bots and spam, and using Laravel's built-in support for the "mews/captcha" package makes it easy to implement.
