Thanks for replies.
To elaborate on the background as to why I asked the question:
I have a function 'delete($id)' which deletes an item from a db.
I then decided to allow the user to select a number of items from a list and to delete all the selected items. So I created another function 'deleteSelected()' which gets all the selected item id's from $_POST, in the form of an array, and then runs throught them and does a delete($id) on them.
I thought it might be cleaner if I could call the single 'delete()' func with 1 or many item id's!
So, that's the background info, which I hope explains how come I don't know the number of parameters which might be passed.
Also, I wasn't sure on what the best practice might be - to pass the id's as an array via $_POST, or as parameters via the URL!?!?
I guess this is the real nub of the question - why pass via URL instead of via $_POST & / or visa versa?
Cheers
Pete
