So I've tried the code I
previously talked about, and it does have an issue w/ nested pages. I tried a fix from a comment, which sorta worked but not really.
If I use the original code, then the breadcrumbs look like this for every single page:
If I use the fix), the breadcrumbs display this on a nested page:
Code:
Home > Directory > Page
Obviously this is the physical representation on the server. But since the directory where the page is shouldn't be accessed by a visitor, a 404 error pops up when the "link" to the parent page is clicked. So how should the actual code read to get the parent page and not the parent directory?
Here's the "working" code:
PHP Code:

function breadCrumb($PATH_INFO) {
global $page_title, $root_url;
// Remove these comments if you like, but only distribute
// commented versions.
// Replace all instances of _ with a space
$PATH_INFO = str_replace("_", " ", $PATH_INFO);
// split up the path at each slash
$pathArray = explode("/",$PATH_INFO);
// Initialize variable and add link to home page
if(!isset($root_url)) { $root_url=""; }
$breadCrumbHTML = '<a href="'.$root_url.'/" title="Home Page">Home</a> > ';
// initialize newTrail
$newTrail = $root_url."/";
// starting for loop at 1 to remove root
for($a=1;$a<count($pathArray)-1;$a++) {
// capitalize the first letter of each word in the section name
$crumbDisplayName = ucwords($pathArray[$a]);
// rebuild the navigation path
$newTrail .= $pathArray[$a].'/';
// build the HTML for the breadcrumb trail
$breadCrumbHTML .= '<a href="'.$newTrail.'">'.$crumbDisplayName.'</a> > ';
}
// Add the current page
if(!isset($page_title)) { $page_title = "Current Page"; }
$breadCrumbHTML .= '<strong>'.$page_title.'</strong>';
// print the generated HTML
print($breadCrumbHTML);
// return success (not necessary, but maybe the
// user wants to test its success?
return true;
}
?>
And here's the actual code that calls the breadcrumb.php file:
PHP Code:
<?php breadCrumb($PATH_INFO); ?>
//the original used $SCRIPT_URL instead of $PATH_INFO
