Captcha integration for Laravel

Installing Laravel Captcha Composer Package

Note: If you do not have Composer yet, you can install it by following the instructions on https://getcomposer.org

Step 1. Install package

composer require parsidev/laravel-captcha

Step 2 for Laravel 5.5 and below. Register the Laravel Captcha service provider

{LARAVEL_ROOT}/config/app.php:

'providers' => [
    ...
    Parsidev\Captcha\Providers\CaptchaServiceProvider::class,
],

Using Laravel Captcha

Generate a Captcha markup in your Controller:

<?php 

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;

class MyController extends Controller 
{
    public function getExample() 
    {
        return view('myView');
    }

}

Showing a Captcha in a View:

...
@captcha
<input type="text" id="captcha" name="captcha" autocomplete="off">
 ...

Check user input during form submission:

<?php 

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;

class MyController extends Controller 
{
    public function getExample() 
    {
        return view('myView');
    }

    public function postExample(Request $request)
    {
    	$this->validate($request, [
            'captcha' => 'required|captcha'
        ]);

        // Validation passed
    }
}
