As far as any CGI is concerned there is only one submit, The one that is
pressed. The other one is simply not posted. But be careful using values of
submit buttons ... if the user hits return instead of clicking one of the
buttons you won't get anything. If you want a default value try a hidden
field before the submits with same name.

Subject: multiple submit buttons
Hi all,
I noticed this chunk of code in a site the other day:
<input type="Submit" name="btn" value="Yes">
<input type="Submit" name="btn" value="No">
My GUESS is that if i click the "Yes" button, I magically
get $btn = "Yes" as a var is the receieving PHP script.
I was just about to test this, when I realised that (from
what I can tell) multiple submits are not supported by CGI
spec.
So, even if it works on my browser/platform/server/php
combination, can I be sure it'll work faithfully on all
environments?
Should I be worried about what the browser sends, or what
PHP does with it, etc etc?
Has anyone doen some serious testing on this? Good or bad
stories?
