You can use refind() to look for it. If you create a regex like
"[^a-zA-Z0-9]" to look for things that are not in that character range, and
then do logic based on that. Like so:
<cfif refind("[^a-zA-Z0-9]",mystring) NEQ 0>
<cfset errorstring="You submitted illegal characters, please hit your back
button and try again">
Less server processing to do it client-side, though. In the form field, you
could put a function onChange, like so:
<input type="text"
onChange="if(this.value.match(/[^a-zA-Z0-9]/)!=null){alert('you have put an
invalid value into this field'); this.focus();}">

Subject: need help..
Hi all,
I have a form field and i want to check if there is any special character
typed in instead of alphabets and numbers.
Is there any tag in cf to find it.
I remember doing it in Perl, but not sure of cf.
Any help would be appreciated. Thanks
Vani
