) and have unfortunately run into some difficulties. Because our website uses the ‘GET’ part of PHP (for example:
) we are having problems hyperlinking to previous pages using the breadcrumb, the breadcrumb links successfully but obviously without the get addition on the end of the address.
What we would like to know is that if there is a way that we could set custom links for certain names of pages in the class.breadcrumb.inc.php file (see bottom for attached code).
PHP Code:
<?php
/**

* Purpose of file: Show the directories and their links in path form
* Home > Firstdir > Seconddir > Etc > filename.php
* Information: If you use this script please contact me with a url or
* product information plus the product :) and please keep
* all header information intact. Cheers!
