## Preview

## Installation

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

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

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.dll` to 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.

```php
    'providers' => [
        // ...
        'Mews\Captcha\CaptchaServiceProvider',
    ]
```
for Laravel 5.1+
```php
    'providers' => [
        // ...
        Mews\Captcha\CaptchaServiceProvider::class,
    ]
```

Find the `aliases` key in `config/app.php`.

```php
    'aliases' => [
        // ...
        'Captcha' => 'Mews\Captcha\Facades\Captcha',
    ]
```
for Laravel 5.1+
```php
    'aliases' => [
        // ...
        'Captcha' => Mews\Captcha\Facades\Captcha::class,
    ]
```

## Configuration

To use your own settings, publish config.

```$ php artisan vendor:publish```

`config/captcha.php`

```php
return [
    'default'   => [
        'length'    => 5,
        'width'     => 120,
        'height'    => 36,
        'quality'   => 90,
    ],
    // ...
];
```

## Example Usage
```php

// [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;
    });
```

captcha_src();
