Well, but the other would work, since the first line of manage_delObjects is:
if type(ids) is type(''): ids=[ids]
I can't decide whether I think that's a good thing or not .

However a list with one item is also acceptable. Although you can declare a list with the trailing comma, it is not strictly necessary. That is only necessary for tuples because parens have double meaning in Python. List brackets are unambiguous. -- | Casey Duncan | Kaivo, Inc. | [EMAIL PROTECTED] `--> ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

That said, here is the answer: All DTML is executed on the server before the page goes to the client. That is why your images get deleted by viewing the page. The onclick attribute is only useful for executing client side scripts like JavaScripts, etc. To execute server side code, you must make the user request the method that deletes the images. This is done by sending the server a page request. So, you need to create two objects in Zope to accomplish this. One that displays the images and another that deletes the requested image and redraws (by a redirect) the image display page. Here's an example: dtml method view_images: Delete this image dtml method delete_image: This code is generic enough so that it would work in any folder. You could place these methods above the folder(s) containing the images for greater generality. It might seem a bit confusing how this works if you don't understand acquisition. The view_images method creates a link to each image in the folder you call it for. The link is to the image object itself with the delete_image method appended. This tells Zope to call delete_image in the context of the image the user selects. manage_delObjects is not a method of the image, but the image acquires it from the Folder that contains it. So delete_image passes the id of the image (using getId()) to the manage_delObjects method of the folder containing it. It then redirects back to the view_images method which will be sans the deleted image. hth -- | Casey Duncan | Kaivo, Inc. | [EMAIL PROTECTED] `--> ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
