~& After implementing this one of my installations I felt that populating this with four copies of the same page when editing was less useful. I made a modification to only add the new page if it was different from the previous one,
~& after the line:- ## $crumbs=$_SESSION['breadcrumbs'];##
~& add %%(php)
#only add breadcrumb if new page is different
if ($crumbs[count($crumbs)-1] != $this->GetPageTag() ) {
#to enclose the if / else clause following it

I have created a version that uses the $_SESSION variable, this makes it a bit more usable since it is not dependent on a user being logged in or not.
My persistance in calling this bread crumbs is hopefully no cause for major discussion. I hope people find this useful.
// WikiTrails code V2 based on copyrighted code by G. M. Bowen & Andrew Somerville, 2005.
// Version 2 stores the crumbs in the $_SESSION variable. This makes this feature usable for all users.

# Define the maximum breadcrumbs shown.

Edited on 2005-06-12 03:08:35 by GmBowen [minor code update & rename to WikiTrails]
Additions:
The following code is a simple history trails feature (JavaWoman informed me that "breadcrumbs" are strictly for heirarchical systems & since wiki's are "flat" calling it a "breadcrumb" feature is inappropriate) that can be added to the header.php code to provide a linear history of the last few previously visited pages in the wiki. It only requires a single field added to the users database (add a field called "recentpages" set as type TINYTEXT and set it so it can be null (which is the default)) and it seems to work like a charm. I was inspired by the trail feature at coocoo wakka, but wrote this from scratch.
// WikiTrails code V1.1 copyright by G. M. Bowen & Andrew Somerville, 2005.
$page_trail .= $separator."[[".$this_pagename."]]";

Version V1.1 fixes search and replace issues. Problem was that if you were at the page ""AndrEw"" and you also had a page ""AndrewsPage"" then when you moved around sooner or later you'd get ""sPage"". That problem is now solved.
