Laravel 4 - 在一个页面上使用多个分页器

I've been googling for this question but can't find any good answers. I found that there is a method called setPageName() for the paginator but it only works when used like Paginator::setPageName('page').

I looked up the paginator in the Laravel API (http://laravel.com/api/class-Illuminate.Pagination.Environment.html) and the method is a public function just like setBaseUrl which I am currently using like $albums->setBaseUrl('/album/');

for instance I want to have a Photo paginator (?photoPage=n) and a Comment paginator (?commentPage=n).

Is there any way that I can use two paginators that use different page names in the URL on one page, or at least call the setPageName() method like setBaseUrl()?

There are actually two classes at play here:

• Illuminate\Pagination\Paginator
• Illuminate\Pagination\Factory

Where the Factory class actually orchestrates the creation of Paginator instances. After a quick glance, I couldn't really tell you why the Factory class is in charge of get/setPageName(), but that's where they live.

It seems that you would need two distinct Factory instances, which, fortunately, is possible via the IoC Container. Since the PaginationServiceProvider binds to paginator, calling $app->make("Illuminate\Pagination\Factory") twice should generate two distinct factories. If you're using namespaces, a service provider to inject the factories into your controller might look like:

class DoublyPaginatedControllerServiceProvider extends ServiceProvider {
    public function register($app)
    {
        $this->bindShared('paginator.photos', function ($app) {
            $factory = $app->make('Illuminate\Pagination\Factory');
            $factory->setPageName('photoPage');
            return $factory;
        });

        $this->bindShared('paginator.comments', function ($app) {
            $factory = $app->make('Illuminate\Pagination\Factory');
            $factory->setPageName('commentPage');
            return $factory;
        });

        $this->app->bindShared('Namespace\DoublyPaginatedController', function ($app) {
            return new DoublyPaginatedController(
                $app['paginator.photos'],
                $app['paginator.comments']
            );
        }
    }
}

Of course, the downside here is that you can't use Eloquent's Model::paginate() -- you'd need to manually determine which set of items to get and pass them to each Factory's make() method.
