Need Help With REFind

I have a form filed and need to make sure that there is not URL's being passed through it.  I would like to search the field and test it for "http" and/or "www", if those charters are present I would like to send it to a special page that handels it and then abort the rest of the script.

Can anyone help me with this?

Thanks!

Nick

    See if this helps.  It's from my regex cheat sheet.

    <cfset regex = "^(http://|www)[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(/\S*)?$" />

    Then :

    #refind(regex,"your_string")#

    Should return 1 if there's a match, or 0 if there isn't.

    Paul,

    You were spot on with your post, I can't thank you enough for your help!

    Have the code in place and it is working like a charm.

    Paul,

    After a bit more testing I noticed that your regex was not working.  I had to use the following code to getthe script to work:

    <cfset stringToSearch = '#form.xxx#'>

    (Notice, I had to use single quotes instead of double quotes, the double quotes were killing me!)

    <p>

    <cfset foundit = '#FindNoCase("http",stringToSearch)#'>

    <cfif foundit gt 0>

            <cflocation url="http://www.xxx.com">

            <cfabort>

    </cfif>

    Had to use:

    #refind("http","your_string")#

    Instead of:

    #refind(regex,"your_string")#

    Have no idea about Regular Expressions, wish I understood what your code is doing so that I could work on it to get it to work but all I know is that the script works this way and I will take it!  :-)

    Thanks again for your help!
