I solved this in one instance by giving all the input tag names names like
XXXtagname, where XXX is a zero-padded number. The order of display is
determined by the form's author, so you could have
then in the cgi handler you simply sort them, then strip the first three
Another thing to check if you have access to it is the raw QUERY_STRING. I
believe browsers are supposed to (or at least do by convention) assemble the
string based upon the order of arguments in the form. That way you can have
two fields named "address" and know that the order you see will be the same
as the order in which the user typed their street address and suite number.
