... Yes, that is a list, but not the list I'm looking for. What I want is an exhaustive list. If the person selected every other checkbox in the above example, starting with the first one, I want zope to return a six element list like below.
['1','','3','','5',''] Zope cannot do this for you without application knowledge:
As of the HTML spec, a checkbox is only successful, if it is checked. Unsuccessfull form controls do not contribute to the form result set. Zope has no chance to detect them from the request data.
Your application (Python Script) can have a list of possible checkbox values and build the list you want from that available in the request.
Actually there is another way, purely HTML and forms processing. It's a bit wierd, but it will work. For every check box, include another hidden field of the same name. You can set the value to anything you like, maybe "not checked". Make it a list type field (the checkbox too) by using the ":list" syntax. Then if a check box of the same name has been checked, for that variable name, your REQUEST will contain a list of length 2, but if not you get a list of length one. This is easy to test for with dhtml. Cheers, Tom P
