Laravel的自定义过滤器

I have an application with many user roles. Like Admin, Manager etc.

There are some instances where both Manager and Admin has the same permission to see/edit a page. In the route.php I created a filter group for Admin access only.

//filter.php
    Route::filter('admin', function()
    {
        if (Auth::guest() or ! Auth::user()->isAdmin()) {
            return 'Not Authorized';
        }
    });

//route.php
  Route::group(['before' => 'admin'], function(){
    //Some routes.....
  });

Now, I want to check if the user is allowed to view that page by checking the userId and the courseId. How can I get these values in the filter.php?

I have a function which checks if the user is authorized for that page. But it requires two variables to be passed (Atleast one variable, the courseId)

public static function isAllowed($userId, $courseId){
//Some conditions. 
}

How can I do this?

It's quite easy actually. In filter.php you simply need to add your filter function and then use it on the routes.php

To Decalre a filter for Route::get('my/url/{variable1}/{variable2}):

Route::filter('myAweSomeFilter', function($route)
{
    $variable1 = $route->getParameter('variable1');
    if (thisAndThat)
    {
        doStuff;
    }
});

now, If you want to call a model function, you can do that inside this function.

Therefore, if you have a model named AuthModel, and a static function named coursePermissionCheck, simply call it as AuthModel::coursePermisssionCheck() and so on. You also write a whole new function inside of the filter function and use it. It's just another function that tells the RouteController what to do if a certain condition is not met.

How to use this filter: 'before' => 'admin|youFilter'

Hope this helps.
