Collecting Web Form Information Using a Loop

[Mike Bonner]

Oh yeah, to do it the way you want, change yours to

       put $_POST[("Q" &  i)] &  comma after theSubmission

The way it was setup to begin with, you're trying to match a key with quotes
because you explicitly put quote & q etc in for evaluation. So in effect it
would return a non-existant array entry because its looking for the quotes.

However, the repeat for each is probably easier all around just because you
can set your script up to handle a changing number of post variables. Repeat
for each key will find however many are sent so that you can parse them and
don't have to mess with concatenating a string together. Also means you can
name them anything you want.  The only side affect of this is that since
arrays are unsorted, if you need results returned in a specific order based
on post variable name you'll need to sort them yourself.

IE:

put the keys of $_POST into tKeys
sort tKeys
repeat for each line theKey in tKeys
do your stuff here with $_POST[theKey]
end repeat
