RE: [PHP] form submission error trapping

sure - $error could be an array, so the code I supplied could be changed to: if you're email client supports rich text, then the changed lines are in green <? // filename: here.html if ($submit) { $error = array(); if (trim($email) == "") { $error["email"] = true; } // process more... if (count($error) == 0) { // do stuff here, maybe a header("location:...."); exit; } } ?> <html> <form action="here.html" method="post"> <? if ($error["email"]) echo "Error: please fill in your email address"; ?> <input type="text" name="email" value="<?= $email; ?>"> <input type="submit" name="submit" value="Go For It!!!"> </form> </html> -----Original Message----- From: Jason Dulberg [mailto:jdulberg@sympatico.ca] Sent: Monday, February 18, 2002 10:40 AM To: Martin Towell Cc: php-general@lists.php.net Subject: RE: [PHP] form submission error trapping Thanks for the code.... Is there a way to keep track of what fields had the errors as its possible for people to have like 5 errors? Thanks again.

Right now, I have something like if (!$submit) { display form } else { process if (trim($email)=="") { echo "error, hit back button to fix"; } } Thanks Jason > -----Original Message----- > From: Steven Walker [ <mailto:steve@walkereffects.com> mailto:steve@walkereffects.com] > Sent: February 17, 2002 6:18 PM > To: jdulberg@sympatico.ca > Cc: php-general@lists.php.net > Subject: Re: [PHP] form submission error trapping > > > Jason, > > I just finished one of my form pages, and I'm really happy with how it > turned out. > > I created one php page that both displays the form and validates the > input.
