Problem
Sometimes you may find the need to output a trail of breadcrumbs which simply reflect the directory structure of where you are in the site, including the current template (.cfm file).
Solution
By looping over the cgi.script_name variable, we can cut up the various paths into individual entries which we can then output.
Detailed explanation
<cfscript>
//Start a new query which we can fill
qBreadcrumbs=QueryNew("url,title",
"varchar,varchar");
//The starting link
link="/";
</cfscript>
<cfloop list="#cgi.SCRIPT_NAME#" delimiters="/"
index="i">
<cfscript>
// Add a row to our
query
QueryAddRow(qBreadcrumbs, 1);
// Set the row with URL
QuerySetCell(qBreadcrumbs, "url", link & i);
// Set the row with the
title: If '.cfm' exists, remove it, and replace underscores with
spaces
// You could also use the
TitleCase() function (see
http://lab.artlung.com/coldfusion-titlecase/ ) to auto capitalise
QuerySetCell(qBreadcrumbs, "title", "#replace(replace(i, '_', ' ',
'all'), '.cfm', '', 'all')#");
//Update the link
location for the next loop
link=link & i &
'/';
</cfscript>
</cfloop>
<cfoutput>
<div id="breadcrumbs"><cfif qBreadcrumbs.recordcount
GT 1><p><a href="/" title="Home">Home</a>
<cfloop query="qBreadcrumbs">
<cfoutput>
<cfif title NEQ "index"> » <a
href="#url#" title="#title#">#title#</a></cfif>
</cfoutput>
</cfloop>
</p></cfif>
</div>
</cfoutput>
