[Zope] Image Submit Buttons

This actually isn't a problem with Zope; it's how the Image type is
interpreted.  The "value" tag has no meaning for Images.  What you want is
this:

<input type=image src="add.gif" name="add">
<input type=image src="delete.gif" name="delete">

Then when you click on the add button, you'll get these two values in your
REQUEST space:
  add.x
  add.y

So, to check for which button you've pressed, you'll have to do:

  <dtml-if "REQUEST.has_key('add.y')">
    ...
  <dtml-elif "REQUEST.has_key('delete.x')">
    ...
  </dtml-if>

That's just how forms work, nothing Zope specific. :)

Hope that helps,
