Re: [Zope] How to require an @ symbol in email form field??
Couldn't you do something similar to Squishdot's "validArticle" dtml method? In addition to verification that the fields are filled in, you could pass the email variable off to a python regular expression that checks for [EMAIL PROTECTED] syntax. -ed- At 07:21 PM 7/21/00 -0400, you wrote: On Tue, 18 Jul 2000, Duncan Booth wrote: Use javascript to check that all required fields are present before the form is actually submitted.

Re: [Zope] How to require an @ symbol in email form field??
The nicest way would be to use a JavaScript clientside script on the form page. I think you can find a good one @ javascript.internet.com If you don't want to use Javascript, you can use the regular expression found from the javascript and use it in a python method of module. - Original Message - From: Stacy Formby [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, July 17, 2000 7:57 PM Subject: [Zope] How to require an @ symbol in email form field?? Hello, I am new to Zope; since our webmaster left I'm trying to make small changes to the website. We have a standard registration form that collects information from users (first name, last name, email, company name, etc.) All of the fields are required, except address 2, address3. Great. fine. If the user doesn't fill out a field, they get an alert. But they can fill each field out with gibberish--as long as there is a character in the input, we accept it. Is there a way to require at least an "@" sign in the email field? The powers that be think this would be useful. Here's the form processing code as it stands today. Any help is appreciated.

Is there a way to require at least an "@" sign in the email field? The powers that be think this would be useful. dtml-unless "'@' in REQUEST.email"... complain here .../dtml- unless Here's the form processing code as it stands today. Any help is appreciated. Use javascript to check that all required fields are present before the form is actually submitted. Here is some of the code I use: SCRIPT Language="Javascript1.2" src="jsvalidate"/SCRIPT form action="..." method="post" onSubmit="return Validate(this);" /SCRIPT where jsvalidate is a DTMLDocument that may be found at http://www.zope.com/members/Duncan/jsvalidate. Also, consider using the :default modifier on fields to force them to have a value. For example, if you put input type="hidden" name="field1:default" value="whatever" then if the field is left empty, or in the case of a radio button not selected, the default value will be used. !-- Check whether any fields are missing. -- ... code snipped ...
