two ways:
1. Javascript on the page with the form. Either use <cfinput
required="yes" message="Please enter your name">, or roll your own.
Problems - requires Javascript to be enabled in the browser to work, so
disabling javascript gets around the validation.
2. Server-side with validation. On the page you submit to, have
something like:
<cfparam name="Form.fieldname1" default="">
<cfparam name="Form.fieldname2" default="">
<cfif NOT Len(Trim(Form.fieldname1))>
<cflocation url="page1.cfm?error=fieldname1">
</cfif>
<cfif NOT Len(Trim(Form.fieldname2))>
<cflocation url="page1.cfm?error=fieldname2">
</cfif>
Then on the first page, have something like:
<cfparam name="URL.error" default="">
<cfif Len(URL.error)>
<cfswitch expression="#URL.error#">
<cfcase value="fieldname1">
You must enter a value for fieldname 1
</cfcase>
<cfcase value="fieldname2">
You must enter a value for fieldname 2
</cfcase>
</cfswitch>
</cfif>
Very basic, but gives you an idea of what to do. Of course I'm
assuming this is why you want to know if the field is empty.
