Can't Access $_POST variables

Asked by IT79637 in PHP Scripting Language, Hypertext Markup Language (HTML)

Tags: ,

Hi Experts,

This is a major rush job for me.  Points=500.

I'm navigating from 1 web page to a 2nd web page and do not have access to $_POST variables in the 2nd web page.  There is an intermediate page between the first two pages that contain frameset and two frames.  Explained below.

I want to pass three data values on the first page to the second web page.  The first is from a hidden field and the 2nd and 3rd are from two drop down boxes.  See "WEB PAGE 1" below.

The intermediate second web page is setup with the usual stuff as follows:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta .... " />
<title>Regular Voucher Entry</title>
<title>Regular Voucher Entry</title>
<link href="images/ss.css"  rel="stylesheet" type="text/css" />
<link href="images/ss.css1" rel="stylesheet" type="text/css" />
<link href="images/ss.css2" rel="stylesheet" type="text/css" />
<style type="text/css">
div {
      display:inline;
      white-space:nowrap;
}
...... more in line style sheet code...
</styLe>
<<-- NEXT A BUNCH OF JAVASCRIPT FOR AN AJAX FUNCTION -->>
<script type="text/javascript" language="JavaScript1.2" src="C:/wamp/www/resume2/scripts/menu.js"></script>
<script type="text/javascript" src="./scripts/jquery-1.2.1.js"></script>
<script type="text/javascript">
$(document).ready(function() {

<<-- DELETED JAVASCIPT -->>

});
</script>

</head>
<?php
session_start();
?>
  <frameset rows="100%,*" >
    <frame name="MAIN"     src="vchrAdd.php" />
    <frame name="HIDDEN" src="ServerControl.html" />
  </frameset>
</html>

However note I have a frameset and two frames.  The first frame  displays the page content.   The second frame is hidden and is used to maintain the handle to a persistent automation server written in Delphi for the life of the browser session.

I assume, IE6 sees the first frame and executes program vchrAdd.php.

The first few lines of vchrAdd.php are:

<?php
session_start();
$id = $_POST["id"] ;
 echo "$id:", $id, "<br>";


if (isset($_POST["nextVchrID"])) {
    $vchrID = $_POST["$nextVchrID"];
} else {
    $vchrID = "NEXT";
}

Then variable I want to access is $id which came from the hidden field on the first web page.  It is always null.  It use to work before I added Framesets and Frames.  I conclude the frameset and frames are the culprit.

Is that correct?

What kind of change do I need to do so I can reference my $_POST variables in program vchrAdd.php or have I royally messed it up?

Thanks much!!!
