I'm having a problem with my Enhanced Inventory Spoilers script. I want to distinguish if somebody visits their inventory from the menu (in which case the url is "/inventory.php"), or if they visit it from a different inventory page (where the url will be "/inventory.php?which=N"). It would be quite helpful if make_url() worked with zero arguments, as this would solve my problem, though I am of course open to suggestion as to how to do this otherwise.
