##安装

{
	"require": {
	    "laravel/framework": "4.0.*",
	    "unodepiera/simplecaptcha": "dev-master"
	},
	"minimum-stability": "dev"
}

使用 composer update 更新您的包或使用 composer install 安装。

使用方法

在 app/config/app.php 中找到 providers 键并注册 Captcha 服务提供者。

	'providers' => array(
        //...
        'Unodepiera\Simplecaptcha\SimplecaptchaServiceProvider',
    )

在 app/config/app.php 中找到 aliases 键。

	'aliases' => array(
        //...
        'Simplecaptcha'  => 'Unodepiera\Simplecaptcha\Facades\Simplecaptcha',
    )

使用以下命令发布资源。

$ php artisan asset:publish unodepiera/simplecaptcha

captcha 选项

您可以为 captcha 设置以下选项。

	$defaultOptions = array(
		"font"			=>	"PT_Sans-Web-Regular.ttf",
		"width" 		=> 	250,
		"height" 		=> 	140,
		"font_size" 	=> 	25,
		"length" 		=> 	6,
		"num_lines" 	=> 	"",
		"num_circles" 	=> 	"",
		"text"			=>	"",
		"expiration"	=>	600,
		"directory"		=>	"packages/unodepiera/simplecaptcha/captcha/",
		"dir_fonts"		=>	"packages/unodepiera/simplecaptcha/fonts/",
		"type"			=>	"alpha",
		"bg_color"		=>	"181,181,181",
		"border_color"	=>	"0,0,0"
	);

• 字体：captcha 的字体类型，查看文件夹 public/fonts。
• Num_lines：captcha 的线条数量。
• Num_circles：captcha 的圆圈数量。
• Expiration：captcha 被删除所需的时间（秒数）。
• Directory：保存 captcha 的文件夹。
• Dir_fonts：保存字体的目录。
• Type：alpha 或 alphanum。

示例用法

	Route::get("form", function()
	{

		$options = array(
			"width"			=>	280,
			"height" 		=> 	100,
			"font_size" 	=> 	28,
			"length" 		=> 	8,
			"num_circles" 	=> 	0,
			"num_lines" 	=> 	4,
			"expiration"	=>  600,
			"bg_color"		=>	"20,20,20"
		);

		$captcha = Simplecaptcha::captcha($options);
		return View::make("form", array("captcha" => $captcha));

	});
	Route::post("process", function()
	{
		$rules =  array('captcha' => array('required', 'captcha'));
	    $validator = Validator::make(Input::all(), $rules);
	    if($validator->fails())
	    {

	    	echo "fails";

	    }else{

	    	echo "success";
	    	
	    }
	});

现在您可以在视图中按照以下方式使用 captcha

    <table>
        {{ Form::open(array('url' => 'process')) }}
        <tr>
	        <td>
	        </td>
	        <td>
	            {{ $captcha["img"] }}
	        </td>
        </tr>
        <tr>
            <td>
                {{ Form::label('captcha', 'Captcha') }}
            </td>
            <td>
                {{ Form::text('captcha') }}
            </td>
        </tr>
        <tr>
            <td>
            </td>
            <td>
                {{ Form::submit('Success') }}
            </td>
        </tr>              
            {{ Form::close() }}
  </table>
