Laravel框架中扩展函数、扩展自定义类的方法,laravel框架
一、扩展自己的类
在app/ 下建立目录 libraries\class
然后myTest.php 类名格式 驼峰 myTest
复制代码 代码如下:
class myTest
{
public function test()
{
return '1asdasd111';
}
}
在 app/start/global.php
复制代码 代码如下:
ClassLoader::addDirectories(array(
app_path().'/commands',
app_path().'/controllers',
app_path().'/models',
app_path().'/database/seeds',
app_path().'/libraries/class', //增加这一段
));
用 make 载入
复制代码 代码如下:
class HomeController extends BaseController {
protected $layout = 'layouts.main';
public function index()
{
$a = App::make('mytest'); // 用法
echo $a->test();
}
}
二、扩展自己的函数
在app/ 下建立目录 libraries\function
建立helper.php
函数格式,如下用function_exists,防止与系统重名
复制代码 代码如下:
if (! function_exists('test2'))
{
function test2()
{
echo 2222222222222222;
}
}
方法一:
在 app/filters.php
复制代码 代码如下:
App::before(function($request)
{
require app_path().'/libraries/function/helper.php'; //载入 自定义函数
});
方法二:
在app/bootstrap/autolad.php
复制代码 代码如下:
require __DIR__.'/../app/functions.php'; // 引入自定义函数库
我感觉方法一会比较好。
default.aspx的代码:
sq s = new sq();
.........
.........
%>
如果在default.aspx.cs文件下引用DLL:
先在项目引用下添加shangqi.dll引用,然后在代码里加上using shangqi;
这样就OK了、、、
你好:
你要在自定义的函数里面的第一个参数设置为:
self
这是python约定的;
调用的时候可以不用管它,它相当于this!
