First of all i don't really know if it is the right forum to post in, if not please any one move to the right place, thanks.
I'm develeoping a dropdown menu that is filtering diferent categories from posts.
I'm currently using query_posts function like this:
The get $_GET['operation'] and $_GET['type'] are passed obviously by get params from the form dropdown menu.
When I pass the 2 values throught the form the query runs correctly, it displays the posts within the correct categories selected, all good.
The trouble comes when at the form I'm not defining any one of the get values, so the get from the url is like empty.
It Runs correctly.
The query or whatever i can't see breaks and displays that there are no results.
