[Zope] processing checkbox parameters - browser differences

[Thomas B. Passin]

With any problem like this, the first thing to do is to make sure what
exactly the form is returning.  You can use something like <dtml-var
"REQUEST.form">.  If that seems OK, then do the <dtml-in> iteration but just
display the value  rather than passing it to some other method or object.

IE 5 will return check box values just fine.  You should also check the html
that the browser sees to make sure that it is exactly what you wanted.
Also, if you have more than one check box with the same name, that can
confuse your code (though I don't see why it would be different for IE vs
NS).

If the html isn't working right, hard code the html and work with it until
it works right.  Then rewrite your dtml to create that same html.

If you have to ask the list about this after taking these steps, please show
what the form's html looks like (remove any unnecessary elements), including
encoding, method, and action.


Cheers,
