Hello, I am looking around for a good PHP breadcrumbs navigation script that would out put a path based on file structure. For instance if I had a folder called Portfolio and within that folder I had a index.php file and another file called Websites.php. When I was on the websites.php page, the breadcrumbs path would display Home >> Portfolio >> Websites and Home and Portfolio would be hyperlinks. I don't want the breadcrumbs to display a .php extension. I could of course hard code this, but would rather find an automated solution. Thanks in advance for any assistance!

I wrote this script quite a while ago (in PHP3.0, if I recall correctly); it could probably stand to be cleaned up, but it works OK. You can tell it the URL path you'd like referenced as the top level of the trail, the default separator (in your case, '&gt;&gt;'), any extra attributes you want in your A HREF tag, and what file names it should ignore. By default, it ignores anything starting with index - eg index.php, index.html. It also replaces underscores with spaces in the current directory/filename, and uppercases the resulting words. Of course, you could remove/alter that functionality if you want. Hope that email client linewraps don't muck it up too badly... steve <?php function path_to_crumbtrail($TopLevel='', $Separator='&nbsp;|&nbsp;', $LinkAttr='', $IgnoreName='index') {
