Issues using .split() and .get(index) in Velocity email templates

We're add UTM tags to links in our email templates and need to split the post URL into 2 parts so it can be rendered as follows:

Example: ${urlPath}?utm_tags#${urlHash}

I've been unable to successfully use the Velocity .split() and .get(index) functions. Anyone else tried this or have another solution?

Separately, any idea which Velocity version is running on Lithium?

Thanks

    I believe you should be able to do something like this:

    #set ($splitPath = urlPath.split(","))
#foreach ($path in $splitPath)
  ${path}
#end

    Thanks DougS

     

    We ended up doing this, which seems excessive but worked:

            #set ($postUrl = $notification.message.webUi.url)
        #if ($postUrl.contains('#'))
          #set ($splitPostUrl = $postUrl.split('#'))
          #foreach ($part in $splitPostUrl)
            #if ($velocityCount == 1)
              #set ($urlPath = $part)
            #elseif($velocityCount == 2)
              #set ($urlHash = $part)
            #end
          #end

          <a href="$!{urlPath}?${utmTag}#$!{urlHash}">
        #else
          <a href="${postUrl}?${utmTag}">
        #end

    This isn't much documentation here: https://velocity.apache.org/engine/1.5/user-guide.html#loops

    Unfortunately $arr.get(index) does not seem to work even though Lithium is using Velocity v1.5

    Velocity just exposes java objects and so the methods you can call on them are the public methods on that java object.

     

    The .get method they are using in https://velocity.apache.org/engine/1.5/user-guide.html#loops is an example when looping over a Hashtable (which has a  public get method). In that article they use this example:

    $allProducts.get($key)

     $allProducts in that article is a Hashtable, so it has a .get method.

     

    In your case, you use the .split method to split a string into a String array. Arrays don't have a .get method:

     #foreach ($part in $splitPostUrl)

    You don't need it though, because you have the array element in your loop (the $part variable).

    ttadej Where is the value of $velocityCount assigned?

    ttadej Does your code work? I have tried it in one of our emails and it isn't working as I would expect. Did you change anything in it?
