Variables not being used in all pages.

Hi,
I have a site where each page is made up of 3 pages. i.e. header.php, then the proper page, like index.php or links.php etc and then footer.php at the end. I am trying to program a mood selector, where u select what mood your in, and it displays the site in different colours. This works ok for tables located in the main pages, and footer.php, but not for tables in the header, they seem to leave out the colours for some reason. My pages look basically like this..

#header.php
include($DOCUMENT_ROOT.'/include/database.php');

if ($submit) {
if (colour == "blue")
{
$bgcolor = "blue";
$linkcolor = "blue";
} else if (colour == "red")
{
$bgcolor = "red";
$linkcolor = "red";
} else if (colour == "green")
{
$bgcolor = "green";
$linkcolor = "green";
}
}

function site_header($title) {
echo "
<head>
<title>$title</title>"
?>
</head>
<body bgcolor="#FFFFFF" text="#000000">
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td bgcolor="<?echo "$bgcolor";?>">
<div align="center">Table Contents....</div>
</td>
</tr>
</table>
<?
}
function site_footer() {

}

#mainpage.php
include($DOCUMENT_ROOT.'/include/header.php');

site_header('Website Title');
?>

echo '<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td bgcolor="'.$bgcolor.'">
<div align="center">This is where the main page contents go...</div>
</td>
</tr>
</table>';

include($DOCUMENT_ROOT.'/include/footer.php');
site_footer();

#footer.php

echo '<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td bgcolor="'.$bgcolor.'">
<div align="center">Copyright 2002 etc...</div>
</td>
</tr>
</table>
</body>
';

So the table bacground colours work on the main pages, and the footer, but not in the header. Can anyone see why?

From first glance what I see is your trying to output $bgcolor within a function. You need to pass the $bgcolor into the function as well as the $title. example:

function site_header($title, $bgcolor) {

echo "
<head>
<title>$title</title>"
?>
</head>
<body bgcolor="#FFFFFF" text="#000000">
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td bgcolor="<?echo "$bgcolor";?>">
<div align="center">Table Contents....</div>
</td>
</tr>
</table>
<?
}

Ahh I see! Excellent it worked! Seems to work fine now, except when I relaod the page. Sems to forget what colour to use. I register the session, but it doesn't seem to remember it!

#default colour page is loaded with
if (!session_is_registered("$color")){
$bgcolor = '#717CA5';
$linkcolor = '#4D4D73';
} else {
}

#which colours to use
if ($colour == 'red'){
$bgcolor = '#CB121C';
$linkcolor = '#660000';
} else if ($colour == 'gold'){
$bgcolor = '#FFCF00';
$linkcolor = '#FF6600';
} else if ($colour == 'green'){
$bgcolor = '#0ABE9E';
$linkcolor = '#006666';
} else if ($colour == 'blue'){
$bgcolor = '#BBDDFF';
$linkcolor = '#666699';
} else if ($colour == 'steel'){
$bgcolor = '#7A8A99';
$linkcolor = '#333333';
}

#when u select colour, session is registered
if ($submit) {
session_register("$color");
}

Page loads fine with default colour, select the colour, and it loads fine, but refresh the page, the it looses the colour information!
Any ideas?
Cheers for your help

OK don't worry! Be being a complete muppet! 2 spellings of colour (color) and I was registering "$colour" as a session, and not "colour" ($).
Been a while since I last did php programming, and I'm just getting back into it.
Cheers once again
