[opencms-dev] coding question param.value vs. cms.element.settings['']

[Filip Kratochvil]

Hi Chris,

 

i hink it’s better to use your second example:

 

${cms.element.settings['setting_name']}

http://documentation.opencms.org/opencms-documentation/demos/element-settings/index.html

 

1.       define settings in xmlcontent’s formatter config

2.       read settings value

How request parameters works?

 

You can read param value from URL query string, example:

www.domain.com/abou-us/?key=value

${param.key} = value

 

You can send param value to JSP using dynamic function:

http://documentation.opencms.org/opencms-documentation/content-in-opencms/special-predefined-content-types/dynamic-functions/index.html

 

You can send param value to JSP using JSP include, example starts at line 102:

Subject: [opencms-dev] coding question param.value vs. cms.element.settings['']

 

 I have the following code in a formatter:

 

        <h3>
                 ${content.value.Title} 
          </h3>
          
          <c:set var="showdate"><c:out value="${param.showDate}" default="true" /></c:set>
              <c:if test="${showdate}">
                  <p><i><fmt:formatDate value="${cms:convertDate(content.value.ProjektDatum)}" dateStyle="LONG"  type="date" /></i></p>
            </c:if>
            <p>${content.value.Text}</p>

vs.:

     <c:if test="${cms.element.settings['enable_untertitel']}">
        <h3 class="post-title" ${content.rdfa.Title}>
            ${content.value.Title}
        </h3>
        </c:if>


Actually, what I want to achieve is to make the output of the date dependent on the widget setting "showDate".

But just for the understanding: where is param.showDate wired resp. how does it function?
