Hi

Could someone show me how to write a regular expression to validate a password field in a <CFINPUT>

I want to allow any 6 to 10 character alpha numeric.

No spaces, special char etc.  

Upper and lower case are Ok

Most important is length must be  >= 6 char and <+ 10 char

Thanks
Mike

Something like this would work.  But you should obviously do server side validation as well.
<cfform>
	<!--- using type="text" for demonstration purposes only --->
	Password 
	<cfinput type="text" name="testPassword" 
			validate="regex" 
			pattern="^[a-zA-Z0-9]{6,10}$"
			required="true"
			message="Password must be alphanumeric and 6 to 10 characters in length"> 
	<cfinput type="submit" name="submitButton"> 
</cfform>

> <cfinput  ... validate="regular_expression" pattern="(?!^[0-9]*$)(?!^[a-zA-Z]*$)^([a-zA-Z0-9]{6,20})$">

That does not produce the results: length must be  >= 6 char and <+ 10 char
