Summary of Zope-related information used on the Ohlone College website.

Properties Used for Ohlone College Website

Zope Properties
(updated August 4, 2008)
Name (alphabetical order) Type Valid Value Property of which Zope object Description
breadcrumb string
  • no
  • noother
 Folder (but could also be DTML Document) See comments in z_breadcrumbs.inc.
meta_description string [unique] DTML Document (preferred) or Folder
  • Should be unique for each individual web page (discontinued as a regular practice about 2004 (very time consuming to maintain), but lots of pages still have this property).
  • Can also be property of a Folder then the property values flows down to each page in that folder.
meta_keywords
page_meta string <meta name="NAME" content="CONTENT" /> DTML Document
  • Used to designate a <meta> tag just for that web page, such as: <meta name="robots" content="index,nofollow" />.
page_type string default /

Ohlone College website root directory.

Used a lot with <dtml-if expr> (see dtml-if).

If the page_type property does not exist, Zope will display a KeyError exception when it tries to find the variable. Therefore, it is necessary to assign page_type on the root folder. The page_type property on the root folder is read only when an object (DTML Document, Folder) doesn't have its own page_type property assigned - this is Zope's acquisition feature.
string home /home.html Ohlone College home page
string core /core /core directory
string newarkhome /org/newark/home.html Newark Center home page
title string [unique] DTML Document, Folder, etc. Required property; can be blank (default).
         

<dtml-if> Notes

Test whether a DTML Method exists.

<dtml-if z_local_bottomnav.inc>
  …
<dtml-elif z_global_bottomnav.inc>
  …
<dtml-else>
  …
</dtml-if>

<dtml-if expr>

Test the page_type property.

<dtml-if expr="page_type == 'home'">
  …
</dtml-if>

Using "or" Operator

<dtml-if expr="page_type == 'home' or page_type == 'core'">
  …
</dtml-if>

Using "and" Operator

<dtml-if expr="page_type != 'home' and page_type != 'core'">
  …
</dtml-if>

Get URL and Filename

  • URL has value of the URL, including filename and without query string
  • URL0 has value of the URL, including filename and query string

  • URL# "counts" backward from the end of the URL
  • BASE# "counts" foward from the beginning of the URL

  • URLPATH# excludes the domain name
  • BASEPATH# - does not seem to work like I thought it would

  • If, for example, there is no BASE3 (or 1 or 2 or 4 or 5 or…), there will be a very unfriendly error in the browser
    • So, it's best to test for BASE3 before using it:
      <dtml-if BASE3>
        <dtml-var BASE3>
      </dtml-if>
  • If the value is a directory, the ending slash is not included
  • On the Ohlone website, "home.html" is the filename of a directory's home page, but Zope uses "index_html" as the filename
  • The value of the .endswith('string') function includes a beginning slash

<dtml-if expr="URL0.endswith('/index_html')">
  <dtml-var URL0>
<dtml-elif expr="page_type != 'home'">
  <dtml-if URL2>
    <dtml-var URL2>
  </dtml-if>
<dtml-else>
  <dtml-if URL1>
    <dtml-var URL1>
  </dtml-if>
  [whatever]
</dtml-if>
