README

Only add one useful function for SPA and wechat applications.

Due to the fact that mewebstudio is not merge pull request now, so I publish a new package. This package would delete when mewebstudio add those functions.

Captcha for Laravel 5

A simple Laravel 5 service provider for including the Captcha for Laravel 5.

Preview

Installation

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

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

Require this package with composer:

composer require Heimuya/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.dll to fit the requirements of Heimuya/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' => [
        // ...
        'Heimuya\Captcha\CaptchaServiceProvider',
    ]

for Laravel 5.1+

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

Find the aliases key in config/app.php.

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

for Laravel 5.1+

    'aliases' => [
        // ...
        'Captcha' => Heimuya\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,
        'type'      => 'png'
    ],
    // ...
];

Example Usage

    // [your site path]/Http/routes.php

    Route::any('captcha-test', function()
    {
        if (Request::getMethod() == 'POST')
        {
            $rules = ['captcha' => 'required|captcha'];
            $validator = Validator::make(Input::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() . '">';
        $form .= '<p>' . captcha_img() . '</p>';
        $form .= '<p><input type="text" name="captcha"></p>';
        $form .= '<p><button type="submit" name="check">Check</button></p>';
        $form .= '</form>';
        return $form;
    });
