Hello, I have a php script that I'm writing and I am stuck on a few things:

I have the following link below that I need to carry 2 variables over with.

The first one is the product id, and the
second one is the value of a hidden field which contains the last web page the user was on (document.referrer).


Wben they click on this link they are taken to a php page where I need to
display the contents of these variables.

My code isn't working.

Any help would be appreciated.


<html>
<head>
<title></title
</head>

<body>
<br>

<?
print "$prod";
print "$sReferringSite";
>

</body>
</html>

Replace the second ? with an ampersand & (you only use one ? for a GET request). If you need it to be XHTML, then use &amp; instead of just &.

Cheers,
Jeff

I fixed up the code that Baby Jeffy indicated, but I am still getting no value for variable ReferringSite.
On my first web page on load it displays where I came from.

When I carry the variable forward, to the next web page (web page 2), the value of ReferringSite is ''.

Web Page 1:
<script language="JavaScript">
function setReferrer()
{document.Form1.ReferringSite.value = document.referrer;}
</script>

<body onLoad="setReferrer();">
<form name="Form1">
<input type="text" name="ReferringSite" size="60">
</form>
<A href="</form>

Web Page 2:
<?php
$sTemp = $HTTP_GET_VARS['ReferringSite'];
print "- $sTemp<br>";
?>

Ah, it could be an escape issue:
Code: 
{document.Form1.ReferringSite.value = [b]escape([/b]document.referrer[b])[/b];}
I don't think you need to unescape it server-side in php.

Oh, try changing your second page to:
Code: 
<?php
$sTemp = '';
if (isset($_GET['ReferringSite'])) $sTemp = $_GET['ReferringSite'];
print "- $sTemp<br>";
?>

Cheers,
Jeff

I changed $_GET to $_POST and it still does not work.

I suggest maybe it's time for you to make a trip to Mr PHP Manual - and have a look into some of the examples that are posted as well. Learn about the differences between $_POST and $_GET. That's what is holding you up on this.

Cheers,
Jeff
