Installation

The Captcha Service Provider can be installed via Composer by requiring the mews/captcha package and setting the minimum-stability to dev (required for Laravel 5) in your project’s composer.json.

{     "require": {         "laravel/framework": "5.0.*",         "mews/captcha": "~2.0"     },     "minimum-stability": "dev" }

or

Require this package with composer:

composer require mews/captcha 

Update your packages with composer update or install with composer install.

In Windows, you’ll need to include the GD2 DLL php_gd2.dll in php.ini. And you also need include php_fileinfo.dll and php_mbstring.dllto fit the requirements of mews/captcha‘s dependencies.

Usage

To use the Captcha Service Provider, you must register the provider when bootstrapping your Laravel application. There are essentially two ways to do this.

Find the providers key in config/app.php and register the Captcha Service Provider.

    'providers' => [         // ...         'Mews\Captcha\CaptchaServiceProvider',     ]

for Laravel 5.1+

    'providers' => [         // ...         Mews\Captcha\CaptchaServiceProvider::class,     ]

Find the aliases key in config/app.php.

    'aliases' => [         // ...         'Captcha' => 'Mews\Captcha\Facades\Captcha',     ]

for Laravel 5.1+

    'aliases' => [         // ...         'Captcha' => Mews\Captcha\Facades\Captcha::class,     ]

Configuration

To use your own settings, publish config.

$ php artisan vendor:publish

config/captcha.php

return [     'default'   => [         'length'    => 5,         'width'     => 120,         'height'    => 36,         'quality'   => 90,         'math'      => true, //Enable Math Captcha     ],     // ... ];

Example Usage

     // [your site path]/Http/routes.php     Route::any('captcha-test', function() {         if (request()->getMethod() == 'POST') {             $rules = ['captcha' => 'required|captcha'];             $validator = validator()->make(request()->all(), $rules);             if ($validator->fails()) {                 echo '<p style="color: #ff0000;">Incorrect!</p>';             } else {                 echo '<p style="color: #00ff30;">Matched :)</p>';             }         }              $form = '<form method="post" action="captcha-test">';         $form .= '<input type="hidden" name="_token" value="' . csrf_token() .
