Chris,

 

I thought your solution was elegant and easier to read than mine.  I guess my days of creating my first web site in perl are still sticking with me as I seemed to use regular expressions all over the place back then…  Now I would like to see a one liner solution to this one J

whoops... is using CGI.QueryString cheating? If so, then my solution breaks the rules.... it's also not a one liner. :(

How about this:
 
<cfset reResults - reFind("numPageID=([0-9]+)", CGI.HTTP_REFERER, 1,
true)>
<cfset theNum = mid(CGI.HTTP_REFERER, reResults.pos[2],
reResults.len[2])>

I want to see if someone can come up with a more elegant solution to
this problem.
 
Given:
CGI.HTTP_REFERER will always have a URL variable, "numPageID=xxx"
which is numeric and could be any size number.
The HTTP_REFERER may or may not have other URL variables in any order,
which could be alphanumeric or numeric
The current template needs to pull the value of the "numPageID" URL
variable out of the CGI.HTTP_REFERER
 
I'll show my solution in another post so as not to spoil anyone's view
on this problem, not saying that mine is best, of course!
 
Thanks,
Joe Kelly
