This is going to sound dumb, but I'm not exactly sure how to work with a Query String?! (I'm used to working with "pretty URLs" and mod_rewrites...)
I have a page that lists article summaries like this...
I want to make it so a user can choose a sort option in a drop-down menu, click a "Go" button, and the page is reloaded with a URL like this...
(And article summaries, of course, would now be sorted accordingly)
1.) How do I build the new URL with the Query String?
2.) Do I have to change my mod_rewrite - which already handles the pretty URL - to handle the Query String?
3.) Any security considerations - other than my PHP script has to sanitize the values in the Query String?
