Question

REGEX Help for Coldfusion - In a URL, removing the ? And everything after

Answer 1

+1 A:

This regular expression will do the trick:

^([^?]+)

Just take the second capture group from the match (the first capture group is always the original string itself if it matched).

Answer 2

+2 A:

In ColdFusion you could use regex replace:

myURL = REReplace(myURL,"\?.*$","")

That would leave you with everything before the question mark.

Answer 3

+10 A:

You can certainly use a regex for this, but it would be more efficient to use

listfirst(theurl, '?')

which finds the first part of a list delimited by question marks.

good idea.. very coldfusion-y way of doing it!

+1 for a nice simple solution. The list*() functions in CF can be very powerful when used in non-obvious ways.

I agree, I always look to list functions before regex.

Answer 4

A:

@Ben Doom: If I'm not mistaken, the #url# variable is a complex object and cannot be treated as a string or list. The way I go about getting everything before the query string is:

<cfset myURL = "http://" & #cgi.HTTP_HOST# & #cgi.SCRIPT_NAME# />

Obviously, I didn't mean to attempt this op on the url scope. I unthinkingly used 'url' to mean a variable holding the URL in question.

Ben Doom 2009-08-26 01:12:57

Yeah, you know it occurred to me after I wrote my answer that you were referring to a variable with the url stored in it rather than the scope itself. Great answer though, I wouldn't have thought of using that technique.
