开始

Lugit提供简单优雅的方法帮助你实现PHP开发，需要PHP5.0以上的版本支持。

URL映射

Lugit使用PATHINFO模式，如：

http://localhost/index.php/controllername/actionname/parameter0/parameter1/parameter2/

建议使用rewrite将上述URL写成

http://localhost/controllername/actionname/parameter0/parameter1/parameter2/

对于Apache服务器可以在app文件夹下建立.htaccess文件，内容如下：

RewriteEngine on
RewriteCond $1 !^(index\.php|favicon\.ico|robots\.txt)
RewriteRule ^(.*)$ index.php/$1 [L]

更多内容请参见Apache服务器文档。

Controller、Action与Parameter

Lugit将URL映射为Controller、Action和Parameter。

如URL: http://localhost/people/tom/book/comment/

对应的Controller为people，Action为tom，Parameter[0]为book，Parameter[1]为comment

如果缺少Action则默认为index, 缺少Controller同理

如URL: http://localhost/people/

对应的Controller为people，Action为index

如URL: http://localhost/

对应的Controller为index，Action为index

第一个示例: Tom的书评

要处理URL:

http://localhost/people/tom/book/comment/

需要在app目录下的controllers文件夹下建立PeopleController.php文件，内容如下：

<?php
class PeopleController extends Controller
{
    public function tomAction()
    {
        //$this->parameters[0] == 'book'
        $this->setVar('p0', $this->parameters[0]);
        //或 $this->vars->p0 =$this->parameters[0];

        //$this->parameters[1] == 'comment'
        $this->setVar('p1', $this->parameters[1]);
    }
}

在views下建立people文件夹，在里面建立tom.phtml文件，内容如下：

<html>
    <head><title>Hello tom!</title></head>
    <body>
        <p>p0 is: <?php echo $this->vars->p0; ?></p>
        <p>p1 is: <?php echo $this->vars->p1; ?></p>
    </body>
</html>

问题: 其他人的书评

设想网站的用户会有很多，所以会有很多如下的网址：

http://localhost/people/tom/book/comment/

http://localhost/people/luin/book/comment/

http://localhost/people/chen/book/comment/

...

我们可以在PeopleController.php里塞满以人名命名的方法，但在Lugit里有更好的解决方案：

<?php
class PeopleController extends Controller
{
    public function adaptAction($people)
    {
        $this->setVar('people', $people);

        //$this->parameters[0] == 'book'
        $this->setVar('p0', $this->parameters[0]);

        //$this->parameters[1] == 'comment'
        $this->setVar('p1', $this->parameters[1]);
    }
}

对应地，在views/people文件夹下建立adapt.phtml，内容为：

<html>
    <head><title>Hello <?php echo $this->vars->people; ?>!</title></head>
    <body>
        <p>p0 is: <?php echo $this->vars->p0; ?></p>
        <p>p1 is: <?php echo $this->vars->p1; ?></p>
    </body>
</html>

关于adapt

当Controller或Action不能确定时可以使用adapt。

比如要处理URL:

http://localhost/tom/1/

http://localhost/peter/8/

http://localhost/peter/17/

我们只要在controllers文件夹下建立AdaptController.php文件:

<?php
class AdaptController extends Controller
{
    public function adaptAction($num)
    {
        $this->setVar('number', $num);
        $this->setVar('people', $this->controllerName);
    }
}

在views文件夹下建立adapt/adapt.phtml进行处理即可。

处理POST & GET

在Lugit中处理POST和GET的方式是一样的，如http://localhost/sample/?people=tom：

<?php 
class SampleController extends Controller
{
    public function indexAction()
    {
        $this->request->people == 'tom'; //true
    }
}

过滤输入

Lugit提供了优雅的方法过滤输入:

<?php 
class SampleController extends Controller
{
    public function indexAction()
    {
        $var_people = $this->request->filter('trim', 'Class::staticMethod')->people;
    }
}

相当于:

<?php 
class SampleController extends Controller
{
    public function indexAction()
    {
        $var_people = $this->request->people;
        $var_people = trim($var_people);
        $var_people = Class::staticMethod($var_people);
    }
}
Our Mission

We want to make open source more sustainable. The entire platform was born from this and everything we do is in aid of this.
