Don't provide a button at all. Place the quantity for each item in a
text input field so that it may be edited by the user before submission.
I'm guessing that your page may presently be showing the details of the
item(s) as, say, a regular HTML table, with hidden form fields for the
data. But, instead of having the quantity hidden, place it in a normal
field. This way, any, all, or none of the quantities may be updated in
one POST.

Or, if your cart resides solely in $_SESSION, you may still provide the
quantity fields and update later.
