"page Not Found" after submitting form to $_SERVER['PHP_SELF'] through Post Action

[Michael Brennan-White]

If I submit my for using a get action the resulting page loads . If I
use a post action I get an error page saying "The page cannot be
found". I am calling the originating page!!! This happens in IE as
well as FireFox.

This code has been tested on a Win2003 server, IIS6, PHP 5.0.3, mySQL
4.1.8 and it works fine.

The problem server is a Win2k server, IIS5, PHP 5.0.4, mySQL 4.1.11.

Any help would be greatly appreciated especially any tips for debugging
the page.

The lovely code for your review:

<?php
// start the session
session_start();
$_SESSION['CallingPage'] = $_SERVER['PHP_SELF'];
$_SESSION['WhichComputer'] = $_SERVER['COMPUTERNAME'];
$_SESSION['WhichServer'] = $_SERVER['SERVER_NAME'];

$_SESSION['TheirHost'] = $_ENV['REMOTE_HOST'];
header("Cache-control: private"); //IE 6 Fix

$Path2PHP = '../../lib/';

$PageTitle = 'Treasury&nbsp;-- Abandoned Property Search';
$PageHeader = 'Search For Abandoned Property';

if (isset($_POST['submit'])) {
$SectionHeader = 'Abandoned Property Search Results';
}
elseif (isset($_GET['page'])){
$SectionHeader = 'Abandoned Property Search Results';
}
else{
$SectionHeader = 'Search for Abandoned Property';
}
$IncludeMe = 'APHeader.php';
include('APHeader.php');

//Paginator
if(!isset($_GET['page'])){
$page = 1;
} else {
$page = $_GET['page'];
}
//echo 'Page Count: '.$_GET['page'];
// Define the number of results per page
$max_results = 10;

// Figure out the limit for the query based

Holla!

I did not have the time to examine all the code but most of the servers
I've published to are givint Page not Found or error 500 directly if
some variables are missing or something is gone wrong with the script.

A proposition is to examine more carefully the code or database 'cause
as I said I didn't manage to check the code.

Hope I helped! (daughtly ) :)
