ZClass issue
by John E. Vincent 15 Feb '00

15 Feb '00

Okay I've been pouring over documentation for the past week and I just for the life of me cannot figure this out. I had originally created a product to do what I needed it to do but found a reference that ZClass might be easier. Basically what I have is a ZClass that will allow a user to create a template for thier site. The class allows them to upload 4 separate images as well as give the site a title. Now what I want to do is be able to call this ZClass via a link to it directly or or a link to a method which itself calls the ZClass. I've been reading the "Adding ZClass Instances Programmatically" doc for about 3 hours and I'm about fried from it. There has to be something obvious here. Basically I have a method that contains these 3 lines: <dtml-with "manage_addProduct['TemplateCreation']"> <dtml-call "templateCreate_addForm"> </dtml-with> I realized it was actually getting to the form because the traceback complained about not finding standard_html_header, which of course is a part of that form. I went to templateCreate_addForm and changed the standard header and footer lines to actual html. At this point I wasn't so concerned about the fact that it couldn't find those. Now when I go to view the method I get a blank page. Like I said before, I'm really missing something simple here but I can't quite figure out what. Any suggestions? I don't mind a good old RTFM, if you can point me to the right FM ;) -- John E.

Variables and images
by J. Atwood 15 Feb '00

15 Feb '00

(after looking, searching and reading). I get back a variable from a database "name" and want to get the image of the same name (or with the variable) in the "images" folder. <dtml-var "images.<dtml-var name>"> - Does not work <dtml-var "images." + <dtml-var name>> - Does not work I know I am either real close or real far off. Thanks, JMA

by Nico Grubert 15 Feb '00

15 Feb '00

hello, I'm creating some Zclass-instance. Clicking on an Instance which is inside of a folder will show me the property-view so I can change the properties of the object for instance the value for "Name". This little view_html shows all the Zclass-instances which are in the folder. <dtml-in "PARENTS[0].objectValues(['CD'])" sort=id> <tr bgcolor="#FFBB88"> <td><a href="<____?_______>"><dtml-var id></a></td> <td><dtml-var Name></td> <td><FORM ACTION="alter_html"> <input type=submit value=" EDIT "> </FORM> </td> </tr> </dtml-in> What syntax I have do put into the <a href="_____?_____"> to bring me the property view of the instance I clicked? thank you nico
