Hei!
=20
=20
I have with zope developed some simple e-learning program which
teach users safety and security topics such as =93fire protection=94, =
=93first
aid=94,
=93environmental policy=94 and so on. It is intended for hotel staff
personnel.=A8
=20
The program is actually only a large number of web pages with
information.
As in a book this information is divided into chapters and subchapters.
In zope this is done using folders. I have one folder called
=93Fire_protection=94,
one called =93First_aid=94 and so on. These folders then have their
subfolders,
and subsubfolders. These folders share some methods like the=20
standard_html_header, standard_html_footer, and a method for generating
a
table of contents at the first page in each chapter or subchapter.
=20
Now, at the bottom of each page, I have some navigation buttons.
Depending
on where you are in the learning program these are:
=93previous=94, =93next=94, =93table of contents=94, =93first topic=94 =
and =93back to
start=94. The
buttons are generated using a form action method like this:
=20
<td>
 <form action=3D"<dtml-var first_topic>">
 <div class=3D"form-element">
 <input class=3D"form-element" type=3D"submit" value=3D"First Topic">
 </div>
 </form>
</td>
=20
=20
=20
The <dtml-var first_topic> refers to a property with the name
=93first-topic=94 that I
manually give to the folder which holds the first topic in this chapter.
The value
of this property could for instance be =93fire_protection_11=94.
Consequently, I have
manually, and for each folder and subfolder on the entire site, created
properties
for =93previous=94, =93next=94, =93table of contents=94 and =93first =
topic=94. Each time
I create some
subchapter somewhere in the site, I have to manually change the
values of these navigation properties in the neighbor previous and next
subchapter. This in
order to have their navigation buttons point to my new subchapter.
=20
This is not very dynamic. Ideally I should have one navigation method in
the rootfolder,
that created all the navigation buttons on all the pages of each chapter
and subchapter
automatically. And if I added or deleted some chapter (folder) somewhere
in the site, this navigation
method should automatically update my navigation buttons. Do you have
any idea of
how I could create such a navigation method, or in any other way
accomplish this?
=20
Best wishes and kind regards
