KNOWLEDGE BASE

So you want to display random messages on your Umbraco site but are not sure how to do it?

The following XSLT code will take in a node (in this case 1305) and look at the content randomly choosing one to display. You can easily pass in the node to search by using a Content Picker assigned to an alias of source in the macro parameters. Then simply add the following lines to the xslt below before the <xsl:template match="/"> line.

<xsl:variable name="feed" select="/macro/source"/>

Then change the node id 1305 to $source. Now when you add the macro to a page, you will be prompted to select the parent node to search from.

<xsl:param name="currentPage"/>
<xsl:template match="/">
<xsl:variable name="numberOfArticleNodes" select="count(umbraco.library:GetXmlNodeById(1305)/* [@isDoc])"/>
 <xsl:variable name="randomArticlePosition" select="floor(Exslt.ExsltMath:random() * $numberOfArticleNodes) + 1"/>
 <xsl:variable name="randomArticleNode" select="umbraco.library:GetXmlNodeById(1305)/* [@isDoc] [position() = $randomArticlePosition]"/>
 
<!-- start writing XSLT -->
 <div class="cta-text">
 <h3><xsl:value-of select="$randomArticleNode/straplineMessage" /></h3>
 <p><xsl:value-of select="$randomArticleNode/straplineSubMessage" />.</p> 
 </div> 
 
</xsl:template>

</xsl:stylesheet>
