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, '>>'), 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...
