Form Action

[Hannibal]

Hi,

I'm trying to build a fairly tight form validation system that I can use repeatedly. Here's the initial code that I've written so far:

if (isset ($POST['submit'])) {
$errors=0;
echo $error="The following errors occurred while processing your form input.<ul>";
}
if(!isset($POST['ContactName']) |
!isset($POST['Address']) |
!isset($POST['City']) |
!isset($POST['StateOrRegion']) |
!isset($POST['PostalCode']) |
!isset($POST['Country']) |
!isset($POST['EmailAddress']) |
!isset($_POST['Phone']) |
{ if($errors==1) echo $error;}
else{
$where_form_is="http".($HTTP_SERVER_VARS["HTTPS"]
=="on"?"s":"")."://".$SERVER_NAME.strrev(strstr(strrev($PHP_SELF),"/"));

There are two other things I want to accomplish here. First, when an error does occur is to print the actual input box; and, second, to validate the email address.

Can anyone give me some frame to achieve this?

Thanks

<?php
if (isset($doover))
  unset($doover);
if (isset($_POST['submit')) {
$errors="";
$contact_name = $_POST['ContactName'];
$contact_address = $_POST['Address'];
$contact_city = $_POST['City'];
$contact_region = $_POST['StateOrRegion'];
$contact_postcode = $_POST['PostalCode'];
$contact_country = $_POST['Country'];
$contact_email = $_POST['EmailAddress'];
$contact_phone = $_POST['Phone'];

if(!isset($contact_name))
  $errors .= "Name, ";
if(!isset($contact_address))
  $errors .= "Address, ";
if(!isset($contact_city))
  $errors .= "City, ";
if(!isset($contact_region))
  $errors .= "Region, ";
if(!isset($contact_postcode))
  $errors .= "Postal Code, ";
if(!isset($contact_country))
  $errors .= "Country, ";
if((!isset($contact_email)) or (!strstr($contact_email,"@")))
  $errors .= "E-mail, ";
if(!isset($contact_phone))
  $errors .= "Phone, ";

if (strlen($errors) != 0) {
echo "You did not complete the following fields ".substr($errors,0,-2).".<br>\n";
$doover=true;
} else {

$where_form_is="http".($HTTP_SERVER_VARS["HTTPS"] 
=="on"?"s":"")."://".$SERVER_NAME.strrev(strstr(strrev($PHP_SELF),"/"));

// do stuff with the form

}
}

if ((!isset($_POST['submit')) or (!isset($doover)) {

// display form with @$contact_name, @$contact_address, @$contact_city, @$contact_region, etc. 
// as the values so they will be filled in with the partial input from the already submitted, but incomplete form.

}
?>

Feldon,

Thanks for taking the time to put some beef into my original meagre contribution. Really looks like a work of art! 🙂 I'll put the works to the test today, and post the outcome.

All the best.
