[Zope] Simple form problem (again)

27 Apr 2000

      Sorry to return to the simple multi-button problem, sorry, sorry; but I just
can't get it to work in Zope.

I have a table whose rows I want to copy or edit or delete, so I put 3
buttons on each row. The buttons are all of type 'submit', the 3 have names
'copy', 'edit' and 'del', and all the buttons on a row have a unique value
that references the row.

However, when any button is pressed, ALL the buttons are valid according to
the REQUEST, in three dictionaries 'copy', 'edit' and 'del' (and there's no
'submit' entry). And I can't get hold of the unique value of any of them - I
just get the text I'm displaying on the button, which is non-unique. All
details below.

This seems to contravene the HTML4 spec, and what's been discussed here
recently, since I would expect a single valid name / value pair. So I
suppose I'm doing something wrong again, but I would very much like somebody
to point me in the right direction.

Thank you in advance,
Geoff Gardiner

Posted on testform, using <dtml-var REQUEST> shows REQUEST.form as

form
del ['Del', 'Del', 'Del']
copy ['Copy', 'Copy', 'Copy']
edit ['Edit', 'Edit', 'Edit']
