    Media Items Test For No Image

    API Questions

    Hi, I have searched these forums but can't find what I am looking for.

    Using umbraco v 4.5.2 (Assembly version: 1.0.3891.20719):

    I am trying to test for an image field being empty.

    <%if(umbraco.library.GetItem("bannerImage") != "") {%>
                <div class="banner">

                  <umbraco:Item runat="server" field="bannerImage" xslt="concat('&lt;img src=&quot;',umbraco.library:GetMedia({0}, true())/umbracoFile, '&quot; /&gt;')" xsltDisableEscaping="true"/>
     
                </div>
            <%}%>

     

    This is from a user control.

    How do I achieve what I am trying, I have looked at GetMedia but this returns an xml node iterator

     

    Can someone help?

    I ended up going round in circles until I found a snippet pointing at the extensions available in umbraco:

     

            <%if (umbraco.presentation.nodeFactory.Node.GetCurrent().GetProperty("bannerImage").Value != "")
              {%>
                <div class="banner">

                  <umbraco:Item runat="server" field="bannerImage" xslt="concat('&lt;img src=&quot;',umbraco.library:GetMedia({0}, true())/umbracoFile, '&quot; /&gt;')" xsltDisableEscaping="true"/>
      
                </div>
            <%}%>
