checking string submitted in form for expletives

I have a username/password fucntion created for part of my website, and I would like to figure out a way to filter out foul language in either their password or username. How can I create a string of expletives and have it search their username or password to see if they are in the name somewhere?

Thanks!

Yes, you can use findNoCase() to do this. In fact, you can easily combine a list of words with the find, in case the user name has a bad word in it anywhere, even if it is combined with another word. Something like this:

<cfset badWordList = "word1,word2" />
<cfloop list="#badWordList#" index="thisWord">
<cfif findNoCase( thisWord, form.userName )>
bad word found code goes here...
</cfif>
</cfloop>

what is the function of index="thisWord"?

For a list loop, the index hold the current list element.

For future reference, questions like this are easily resolved with a quick look at the documentation:
