Velocity Array Examples

Hey Guys,

I can't seem to find any working array examples for Velocity. I basically want to take the breadcrumb code from github ( and reverse the order for our title pages. My thought was to store what's being printed in an array and reverse the array, but it looks like my syntax is a bit off. I can't really find any good examples of declaring and adding to arrays. Each one I find is different.


PS- if there is a better way to do this, I'm all ears. I don't know Velocity too well.

    Hi Joe,

    To confirm, are you looking to simply reverse the order the breadcrumbs are displayed? For example, the current page would be listed first and the Site's homepage would be listed last?

    If so, you can use some recursion along with the Element.getParent() to traverse up the structure, starting with the current page. The following may be a good starting point:

    ## Some constants
    #set ( $defaultPage = "index" )
    #set ( $separator = "»" )
    ## Reference the home and current pages
    #set ( $homepage = $_XPathTool.selectSingleNode($contentRoot, "//system-page[path = '/${defaultPage}']") )
    #set ( $page = $_XPathTool.selectSingleNode($contentRoot, "//system-page[@current]") )
    #macro (traverseUp $node)
        #set ( $parent = $node.getParent() )
        #if ($parent.getName() == "system-folder")
            <li><a href="${parent.getChild("link").value}/${defaultPage}">${parent.getChild("display-name").value}</a>  ${separator}</li>
        <li>${page.getChild("display-name").value} ${separator}</li>
        <li><a href="/${defaultPage}">${homepage.getChild("display-name").value}</a></li>

    Please let me know if you have any questions.
