Auto-Linking Comments

June 24, 2005

To avoid comment spam, my blog comments are displayed as plain text. However urls to other entries on my blog are often posted to in the comments. So I wrote a simple regular expression to create hyperlinks out of them:

REReplaceNoCase(comments.comment, 
	"(http://www\.petefreitag\.com/[^[:space:]]+)",
	"<a href=""\1"">\1</a>", 
	"ALL")

If you want this to work with or without the www you can use something like this for the regular expression:

(http://w*\.?petefreitag\.com/[^[:space:]]+)

Thanks...

I think the other languages on MXNA are blogs that are actually written in those languages. I could be mistaken perhaps Christain Cantrell or Mike Chambers will read this and can comment further.

BTW if you find an entry to be useful (or not useful) please use my rating system at the bottom of the post.

Then I can construct which posts are most useful, and which are not.

See http://www.petefreitag.com/about/ for a list of most useful posts so far. (ooh that should auto-link)

I prefer the following for auto-linking

cfset linkRegEx = "((http|https):\/\/[[:word:]\-_]+(\.[[:word:]\-_]+)+([[:word:]\-\.,@?^=%&:/~\+##]*[[:word:]\-\@?^=%&/~\+##])?)"

cfset thisComment = ReReplaceNoCase(thisComment,linkRegEx,'a href="\1"[Link]&/a','All')

this regEx matched pretty mugh any URL and even ignores bad trailing punctuation.
