Re: [newbie] Array form values.

Well, I'd need the key - I don't want to have a system that breaks if someone deletes a record while someone else is mulling over the form, before they submit it. So I'm going to need the id number for each record changed. Also, my real form is going to have more than one field doing this - email, rank, and name, that I know of so far. ----- Original Message ----- From: "Toby Butzon" <php-lists@imawebdesigner.com> To: <huntsman@www.nisu.flinders.edu.au> Cc: "April" <april@farstrider.org>; "PHP General" <php-general@lists.php.net> Sent: Tuesday, February 06, 2001 10:36 AM Subject: Re: [PHP] [newbie] Array form values. > Or you might try a foreach($array as $element)... about the same but it > doesn't give you they key - just the value (as $element). > > foreach ($email as $current) { > // process this email addr > } // move on to the next one until the whole arr of them has been proc'd > > Good luck- > > --Toby > > David Robley wrote: > > > > On Tue, 6 Feb 2001 08:57, April wrote: > > > I have a form that is an extended version of this: > > > > > > <form> > > > <input type="text" name="email[1]"> > > > <input type="text" name="email[2]"> > > > <input type="text" name="email[3]"> > > > </form> > > > > > > Unfortunately, the email[1] part was generated using a variable in a > > > loop.
