Laravel Google reCAPTCHA Integration
Google reCAPTCHA is a popular tool to protect your website from spam and abuse while allowing genuine users to pass through with ease. It helps prevent automated bots from submitting forms and provides an added layer of security to your web applications. Laravel, being a widely-used PHP framework, provides a straightforward way to integrate Google reCAPTCHA into your projects. In this guide, we'll walk you through the process of setting up and using Google reCAPTCHA in a Laravel application.
Step 1: Sign up for Google reCAPTCHA
To get started, you need to sign up for Google reCAPTCHA. Go to the reCAPTCHA website (https://www.google.com/recaptcha) and click on the "Admin Console" button in the top-right corner. You'll need to log in with your Google account or create one if you don't have one.
Once you're logged in, you'll see the option to "Register a new site." Fill in your website's name, choose the type of reCAPTCHA (reCAPTCHA v2 "I'm not a robot" checkbox is most common), and enter the domain name of your Laravel application. You'll receive two keys, a Site key, and a Secret key, which you'll need in the next steps.
Step 2: Install Laravel Package
Now that you have your Google reCAPTCHA keys, open your Laravel project in a terminal and use Composer to install the necessary package for handling reCAPTCHA.
```bash
composer require greggilbert/recaptcha
```
Step 3: Configure the Package
Next, you need to add your reCAPTCHA keys to the Laravel configuration file. Open `config/services.php` and add the following lines:
```php
'recaptcha' => [
'site_key' => env('RECAPTCHA_SITE_KEY'),
'secret_key' => env('RECAPTCHA_SECRET_KEY'),
],
```
Step 4: Add the Keys to Your Environment File
Now, open your `.env` file located in the root of your Laravel project and add the reCAPTCHA keys you obtained earlier:
```env
RECAPTCHA_SITE_KEY=your_site_key_here
RECAPTCHA_SECRET_KEY=your_secret_key_here
```
Step 5: Implement reCAPTCHA in Your Forms
To add Google reCAPTCHA to your forms, you'll need to modify your Blade views. Locate the form you want to protect, and add the reCAPTCHA widget just before the form's submit button:
```html
```
Step 6: Validate the reCAPTCHA Response
In your controller where you handle the form submission, you need to validate the reCAPTCHA response. Laravel makes it easy to do this using the `Validator` class. Open the controller that processes the form data and add the reCAPTCHA validation rule:
```php
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator;
public function submitForm(Request $request)
{
// Validate reCAPTCHA
$validator = Validator::make($request->all(), [
'g-recaptcha-response' => 'required|recaptcha',
// Add other validation rules for your form fields here
]);
if ($validator->fails()) {
// Handle the validation failure, typically redirect back with errors
return redirect()->back()->withErrors($validator)->withInput();
}
// Process the form data if reCAPTCHA is validated
// ...
}
```
Step 7: Test Your Implementation
With everything set up, you can now test your Laravel application with Google reCAPTCHA integration. Ensure that the reCAPTCHA appears on your form, and upon successful validation, your form submission should work as expected.
By following these steps, you've successfully integrated Google reCAPTCHA into your Laravel application, bolstering its security against bots and spam submissions while providing a smoother user experience for genuine visitors.
