From the docs http://laravel.com/docs/routing#route-filters

Route::get('user', array('before' => 'auth|old', function()
{
    return 'You are authenticated and over 200 years old!';
}));

I'm assuming you could do a group the same way, but I it's untested.

Thanks, I know about that option. But I have several that need other filtering. That's why I want to nest them and break it down.

@MacWorks, you need to add "prefix" to your route group. Here is section of my route file.

Route::group(['prefix' => 'admin', 'namespace' => 'Controllers\Admin'], function()
{
    // /admin/dashboard
    Route::get('dashboard', [
        'as' => 'admin_dashboard', 
        'uses' => 'DashboardController@getIndex'
    ]);

    ...

    // /admin/members
    Route::group(['prefix' => 'members'], function()
    {
        Route::get('/', [
            'as' => 'admin_members', 
            'uses' => 'UsersController@getMemberList'
        ]);
        
        // /admin/members/search
        Route::get('search', [
            'as' => 'admin_member_search', 
            'uses' => 'UsersController@getMemberSearch'
        ]);

        Route::get('{id}/status', [
            'as' => 'admin_member_inactive', 
            'uses' => 'UsersController@getUserInactive'
        ]);

        Route::post('{id}/remove', [
           'before' => 'isGod',
            'as' => 'admin_member_remove', 
            'uses' => 'UsersController@postRemove'
        ]);
        
        Route::get('mailinglist', [
            'as' => 'admin_member_maillist', 
            'uses' => 'UsersController@getMailingList'
        ]);

    });
    
    ...
});

Can you filter based on prefixes?

Yes you can. Pattern Based Filters

Route::when('admin/*', 'admin', array('post'));

You can also nest groups as explained here: http://www.laravel-tricks.com/tricks/route-group-namespacing Hope it helps!

I also have this issue.

I have route group inside another route group working.

But if I now need to have another route group that the initial route groups must be within, as I need to apply a filter to all routes. I can't add the filter to the first group as the filter is needed before a prefix is added.

So is there some way around this nesting problem? I don't understand how name space groups will help me fix this, but I am quite new to Laravel.

Update: Ofcourse I found the answer soon after making the post.

My problem was that I was using groups for filters in combination with individual filters. It seems you can't apply 3 levels of nested grouping and then a filter to an individual route.

So my solution was to make all routes in groups for each filter, and have no filters applied to an individual route. This may well be documented, but I missed it.

A working example of nested groups with no prefix or namespace

I needed guest filter applied to all 4 routes but csrf only for the post routes.

Route::group(['before' => 'guest'], function()
{
    //only require the guest filter
    Route::get('login', ['as' => 'login.create', 'uses' => 'SessionsController@create']);
    Route::get('register', ['as' => 'register.create', 'uses' => 'RegistrationController@create']);

    //require both guest and csrf filter
    Route::group(['before' => 'csrf'], function()
    {
        Route::post('login', ['as' => 'login.store', 'uses' => 'SessionsController@store']);
        Route::post('register', ['as' => 'register.store', 'uses' => 'RegistrationController@store']);
    });
});
