Subject: best way to see if a var only has certain characters?
Simple question. On one of the fields of a form I need to make sure it
only contains 0-9, A-Z and -. Whats the best way to do this? I could
do it in 30 seconds in perl but am not sure of the best way in CF. The
way I did it when I was first starting CF was like this:
<CFSET
basespan="ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789">
<CFIF SpanIncluding(Form.fieldname, basespan) NEQ Form.fieldname>
<CFSET errstr="Has bad characters!">
</CFIF>
But there might be a better way to do it?
Thank you!
Ryan
