Laravel 4 route with unlimited number of parameter

问题:

I'm trying to create a dynamic route for an unlimited number of URL levels.

Here's my current route

Route::get('{pageLink}', array('uses' => 'SiteController@getPage'));

This works for the first level. So a URL like something.com/foo/ would work. But if I had something like something.com/foo/bar/ it wouldn't catch that URL. I need it to match unlimited levels. That way in my controller it'll get me a variable of whatever the entire link is.

I know I could do

Route::get('{pageLink}', array('uses' => 'SiteController@getPage'));
Route::get('{pageLink}/{pageLink2}', array('uses' => 'SiteController@getPage'));
Route::get('{pageLink}/{pageLink2}/{pageLink3}', array('uses' => 'SiteController@getPage'));

But that just seems like an overkill. Is there a better way to do this so it'll match to the end of the URL?

Thanks.

You can try something like this:

//routes.php
Route::get('{pageLink}/{otherLinks?}', 'SiteController@getPage')->where('otherLinks', '(.*)');

Remember to put the above on the very end (bottom) of routes.php file as it is like a 'catch all' route, so you have to have all the 'more specific' routes defined first.

//controller 
class SiteController extends BaseController {

    public function getPage($pageLink, $otherLinks = null)
    {
        if($otherLinks) 
        {
            $otherLinks = explode('/', $otherLinks);
            //do stuff 
        }
    }

}

This approach should let you use unlimited amount of params, so this is what you seem to need.

You may constrain the format of your route parameters using the where method on a route instance. The where method accepts the name of the parameter and a regular expression defining how the parameter should be constrained. so {id} is a route parameter , and ->where('id', '[0-9]+') is a regex expression for this parameter. If u need to use more than parameters you can do something like this :

Route::get('user/{id}/{id2}', function ($id) { })->where('id', '[0-9]+')->where('id2', '[[0-9]+]');


    Route::get('user/{id}', function ($id) {

    })->where('id', '[0-9]+');
