Use ColdFusion to Find Out What Directory or Folder You're In
Have you ever wanted to find out what folder or directory a particular page or template resides in, but NOT necessarily the entire path to the page? Well, Raymond Camden recently blogged about it, so I know of at least one other developer (including myself) who has asked that question so I thought it would be worthy of mention here.
Ray mentions a number of extremely useful functions and the person who submitted the question was actually quite close to answering their own question (just as I too find myself on so many occaisions).
Let's say you have a file "index.cfm" which resides at "www.example.com/folder/" which as it might turn out translates to "D:\inetpub\example\folder\". Maybe you just want to return "folder" but don't need anything else. Let's try a couple of different options to see what happens.
<cfset thisPath = ExpandPath("*.*") />
<cfoutput>#getDirectoryFromPath(thisPath)#</cfoutput>
This produces "D:\inetpub\example\folder\"
Well, that's not what we wanted is it? Let's try another way.
<cfset thisDirectory = ExpandPath(".") />
<cfoutput>#getDirectoryFromPath(thisDirectory)#</cfoutput>
This produces "D:\inetpub\example\"
Hmm, while this isn't what we wanted, it is kind of interesting. But we're not quite there, so lets try another method.
<cfset thisDirectory = ExpandPath(".") />
<cfoutput>#getFileFromPath(thisDirectory)#</cfoutput>
Aha! This produces "folder" just like we wanted!
Does this help you? Let me know.

1) Using some of the same tags listed in my article you could also get at the current folder using this:
<cfoutput>
#listlast(GetDirectoryFromPath(GetCurrentTemplatePath()), "\")#
</cfoutput>
Or, better yet, ever need to know the drive letter of your web site? Try this:
<cfoutput>
#listfirst(GetDirectoryFromPath(GetCurrentTemplatePath()), "\")#
</cfoutput>
2) Dan G. Switzer, II created a nifty UDF which would work when using virtual directories: (http://blog.pengoworks.com/index.cfm/2008/5/8/Gett...)
3) And one more example:
<cfoutput>
#listlast(GetDirectoryFromPath(cgi.script_name), '/')#
</cfoutput>
