Instead of directing your form to URL0 direct it back to your custom interface. In your form you can evaluate the value of submit to determine the appropriate action: <dtml-if "REQUEST['submit'] == 'Delete'"> <dtml-call "manage_delObjects(ids)"> untested. Roché

Hi Zopers

I've found the "How-To: Adding ZClass Instances Programmatically", but now I'm looking for the *Deleting ZClass Instances* one!

I'm trying this as a beginning (hacked from the Zope management interface)::

<dtml-if "AUTHENTICATED_USER.has_role('ContentManager')"> <form action="<dtml-var URL0>" method="post"> </dtml-if> [...] <dtml-if "AUTHENTICATED_USER.has_role('ContentManager')"> <input type="checkbox" name="ids:list" value="<dtml-var id>"> </dtml-if> [...] <dtml-if "AUTHENTICATED_USER.has_role('ContentManager')"> <input type="submit" name="manage_delObjects:method" value="Delete"> </form> </dtml-if>

Problems:

- it sends me to the management screen afterwards, and I'm calling it from the public interface.

- I don't necessarily want to give the 'ContentManager' rights to delete objects; I'd rather manage this through a delete method with the appropriate proxy role.

Any advice or RTFM pointers? -- Jean Jordaan -- technical writer -- Mosaic Software -- Zope 2.1.6 on WinNT and W2K
