How to Use a CAPTCHA Package in Laravel: Step-by-Step Guide

If you run a Laravel website, you know how important it is to protect your site from automated bots and spam. One effective way to achieve this is by using a CAPTCHA package. With so many different CAPTCHA packages available for Laravel, it can be overwhelming to decide which one to use. In this article, we'll take a closer look at how to use a CAPTCHA package in Laravel, including step-by-step instructions for installation and implementation.

Choose a CAPTCHA Package

First, you need to decide which CAPTCHA package you want to use. In this article, we'll be using the popular Google reCAPTCHA package as an example, but the process for other packages will be similar.

Install the CAPTCHA Package

Once you've chosen a CAPTCHA package, you need to install it in your Laravel application. You can install the Google reCAPTCHA package using Composer by running the following command:

code

composer require google/recaptcha

Register for an API Key

Next, you need to register for an API key with the CAPTCHA provider you've chosen. For Google reCAPTCHA, you can register for an API key by visiting the Google reCAPTCHA website.

Add the CAPTCHA to Your Form

Once you have your API key, you can add the CAPTCHA to your form. For example, if you're using Laravel's built-in form builder, you can add the following code to your form:

code

{!! app('captcha')->display(); !!}

Verify the CAPTCHA

Finally, you need to verify the CAPTCHA when the form is submitted. For Google reCAPTCHA, you can verify the CAPTCHA by sending a POST request to the Google reCAPTCHA API with the user's response and your API key. You can use the following code to verify the CAPTCHA:

code

$response = $request->input('g-recaptcha-response');

$remoteip = $request->ip();

$api_key = env('GOOGLE_RECAPTCHA_SECRET');

$url = 'https://www.google.com/recaptcha/api/siteverify';

$data = array( 'secret' => $api_key, 'response' => $response, 'remoteip' => $remoteip );

$options = array( 'http' => array( 'header' => "Content-type: application/x-www-form-urlencodedrn", 'method' => 'POST', 'content' => http_build_query($data), ), );

$context = stream_context_create($options);

$result = file_get_contents($url, false, $context);

$decoded_result = json_decode($result);

if ($decoded_result->success == true)

{ // CAPTCHA was successful

} else { // CAPTCHA failed

}
