I'm doing a major update to my personal little application framework.
The original was begun in CF 3.0, updated heavily when 4.5 came out and
is now being updated for 5/MX.
One thing I do is set several variables in Application.cfm like so:
<!--- This is the offset from webroot to application.cfm. An
application at the root would use a slash, an application in the
directory "MyApp" would use "/MyApp/ --->
<cfset Request.AppRootOffset = "/">
<!--- Set Application Path for Custom Tags --->
<cfset Request.AppPath = GetDirectoryFromPath(GetCurrentTemplatePath())>
<!--- Get Path information --->
<cfset Request.RootPath =
ReplaceNoCase(GetDirectoryFromPath(GetBaseTemplatePath()),
GetDirectoryFromPath(GetCurrentTemplatePath()), "")>
<cfset Request.RelRootPath = REReplaceNoCase(Request.RootPath,
"[^\]*\\", "../", "All")>
So, with that, if Request.AppRootOffset = "/DepressedPress/" and the
current template is "/DepressedPress/Content/ColdFusion/Index.cfm" then
this might be the result (results will vary with web server
configuration):
Request.AppPath = "D:\WWWRoot\VBoston.com\DepressedPress\"
Request.RootPath = "/DepressedPress/Content/ColdFusion/"
Request.RelRootPath = "../../"
Similarly all custom tags have this code to let them find assets in the
same folder as they are (for example a navigation tags graphical assets
would be in the same folder as the custom tag):
<!--- Set Paths for Tag --->
<cfset TagPath =
ReplaceNoCase(GetDirectoryFromPath(GetCurrentTemplatePath()),
Request.AppPath, "")>
<cfset TagRelRootPath = REReplaceNoCase(TagPath, "[a-z_-]*\\", "../",
"All")>
<!--- Swap slashes for use in HTML --->
<cfset TagPath = Request.AppRootOffset & Replace(TagPath, "\", "/",
"All")>
<cfset TagRelRootPath = Replace(TagRelRootPath, "\", "/", "All")>
Using these variables means that I can move applications around within
the web root, to new servers, etc and only have to change the hard coded
value of "Request.AppRootOffset"
Now I've already converted all of that stuff to UDFs (although I do have
one small regex difference between 4.5/5 and MX that requires server
version conditional processing) and everything's working.
However the fact still remains that I still need to hardcode my
"RootOffset" value and add the UDF call to every custom tag.
I'd like to determine a way to eliminate those needs if at all possible.
How do you folks do this (or am I making things just too damn
difficult)?
I'm not looking for "how to" help - I'm looking for "how should" help.
;^)
I think that I may be able to calculate the Root OffSet using the CGI
variables (CF_TEMPLATE_PATH and SCRIPT_NAME specifically) but I'm not
sure how I possibly do the custom tags (I think that I'll have to live
with that).
I'm working (for various projects) all versions of CF back to 4.01, but
the biggies are all on MX or 5 now so I'd like to keep this applicable
to at least those two. So, unfortunately, no CFCs (yet).
Thanks in advance,
