Cleaning Query Strings in Urls

[Medianomaly]

Hey, if I have a module that lists a bunch of items, but also has a set of fields to filter the listing, when a user chooses an option for one of the filters, the resulting Url looks like this...

/some-page/?a=&b=&c=&d=&e=something&f=

What's the best way to clean out the empty parameters in that? Is there a built-in Contao method for doing this?

Right now I'm looping through all the GET variables, removing the empty ones manually and then redirecting at the end. But I was just curious if there's an easier/more efficient way.

I think it is as simple as

$clean_get = array_filter($_GET);

then you can re-create the url by using the "Controller::generateFrontendUrl" method

Awesome, thanks. Simple indeed.
