breadcrumb help

[foevah]

After trying alot of tutorials on breadcrumbs I have found this one the best so far:

http://gr0w.com/articles/code/php_breadcrumb_links_creator/

 

I have got it to work on my home page but when I use it on another page it doesnt work  :-\

 

On my homepage in dreamweaver I have put this php code on my footer because this is where I want my breadcrumbs:

<?php $pagetitle="Home"; include("http://www.newmedia.lincoln.ac.uk/jecgardner/breadcrumb.php"); ?>

 

This is inside the included file breadcrumb.php:

<?php
$ul_id='crumbs';
$bc=explode("/",$_SERVER["PHP_SELF"]);
echo '<ul id="'.$ul_id.'"><li><a href="http://www.newmedia.lincoln.ac.uk/jecgardner/">Home</a></li>';
while(list($key,$val)=each($bc)){
$dir='';
if($key > 1){
  $n=1;
  while($n < $key){
   $dir.='/'.$bc[$n];
   $val=$bc[$n];
   $n++;
  }
  if($key < count($bc)-1) echo '<li><a href="'.$dir.'">'.$val.'</a></li>';
}
}
echo '<li>'.$pagetitle.'</li>';
echo '</ul>';
?>

 

When I view the page source of my homepage in firefox this is the code I see:

<ul id="crumbs"><li><a href="http://www.newmedia.lincoln.ac.uk/jecgardner/">Home</a></li><li></li></ul>

 

I am not sure why there are so many </li>?

 

I have put the code below on my contact page:

<?php $pagetitle="Contact"; include("http://www.newmedia.lincoln.ac.uk/jecgardner/breadcrumb.php"); ?>

 

When I view the contact page it still says Home and not Home > Contact  :-\ :-\ ???

 

I tried adding a second $pagetitle2:

<?php $pagetitle="Home"; $pagetitle2="Contact";include("http://www.newmedia.lincoln.ac.uk/jecgardner/breadcrumb.php"); ?>

 

and in the breadcrumb file I have added this:

echo '<li>'.$pagetitle.'</li>';
echo '<li>'.$pagetitle2.'</li>';

 

Nothing seems to work. I thought this was supposed to be easy lol

 

Please can someone help!?
