>- see footer for list info -< The best way is to use clientside and server side validation.
Clientside is better for the users that have javascript enabled, cause it means a faster user experience. Server side validation takes care of the users that have javascript disabled. Could be a bit overkill doing both, it depends how thourough you want to be. hth mark -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Stephen Adams Sent: 24 November 2004 16:45 To: Coldfusion Development Subject: RE: [CF-Dev] Best way to check if a form field is empty >- see footer for list info -< Yes it is, generally I am validating forms quiet a lot, and I'm just trying to get an idea of the best method, which I can use every time I need to validate a form. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Duncan Cumming Sent: 24 November 2004 16:30 To: [EMAIL PROTECTED] Subject: Re: [CF-Dev] Best way to check if a form field is empty >- see footer for list info -< 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.
