Properties Used for Ohlone College Website

How to Find Zope Properties Assigned to Folders and/or Files

• Login to Zope
• Navigate to directory where search will start
• Select "Find" in the top menu
• Select "Advanced" link
• Enter this in the "expr" textbox: PROPERTYNAME != ''
  • where PROPERTYNAME is the name of the property to search for (example: page_meta)
  • NOTE: '' is 2 single quotes with no space in between
• Select the "Find" button

<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 "and" Operator

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

Using "or" Operator

<dtml-if expr="page_type == 'home' or
               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 homepage, but Zope uses "index_html" as the filename
• The value of the .endswith('string') function includes a beginning slash

Check true:

<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>

Check false (== 0) / not true (!= 1):

<ul>
<dtml-if expr="URL0.endswith('/scholarshiprecipients-citizenofyear.html') == 0">
  <li><a href="/org/foundation/scholarships/2011spring/scholarshiprecipients-citizenofyear.html">Citizen of the Year Scholarships Recipients</a></li>
</dtml-if>
<dtml-if expr="URL0.endswith('/scholarshiprecipients-otherfoundation.html') != 1">
  <li><a href="/org/foundation/scholarships/2011spring/scholarshiprecipients-otherfoundation.html">Other Foundation Scholarships Recipients</a></li>
</dtml-if>
</ul>
