Two Useful Form Field Validation Functions
Here are two quick ColdFusion scripts to validate if a user supplied a real e-mail address or website URL using Regular Expressions.
To validate an e-mail address:
<cfif REFindNoCase("^[\w\.-]+@[\w\.-]+\.[a-zA-Z]{2,3}$",form.EMAIL) lt 1> <--- E-mail address was not valid.... ---></cfif>... and to validate a website url:
<cfif REFindNoCase("^(http://|https://)[\w\.-]+\.[a-zA-Z]{2,3}(/?)$",form.WEBSITE) lt 1> <--- Website URL was not valid.... ---></cfif>I wanted to post these real quick just so I have them handy, but also you might find them useful as well.
