How do I get message id from Post Page?

On the Post Page, I would like to display a message based on the topic's age.   To do this, I first need to retrieve the ID of the topic message that is being replied to. The following didn't yield...

    Because the message context object is not available on the post page, I found that you need to resort to other methods.

     

    The solution I implmented was to parse the request url with freemarker to grab both the board ID and message ID.  

     

    Here is the freemarker code...

      <#assign boardKey = "board-id">
  <#assign messageKey = "message-id">

  <#assign urlString = http.request.url>
  <#assign strCount = 0>
  <#list urlString?split("/") as subStr>
    <#if messagePos?? && strCount == messagePos>
      <#assign messageID = subStr>
    </#if>
    <#if boardPos?? && strCount == boardPos>
      <#assign boardID = subStr>
    </#if>

    <#assign strCount = strCount + 1>

    <#if subStr == boardKey>
      <#assign boardPos = strCount>
    </#if>
    <#if subStr == messageKey>
      <#assign messagePos = strCount>
    </#if>

  </#list>

  <#if boardID??>
      <div>Board ID: ${boardID}</div>
  </#if>
  <#if messageID??>
      <div>Message ID: ${messageID}</div>
  </#if>

Amazed this object still isn't available on such an important page.

 

Either way, I found this, albeit ugly, to be the least required code to get the unique id

 

<#assign u = http.request.url/>
<#assign msg_non_unique_id = u?substring(u?last_index_of("/") + 1, u?length)/>
<#assign msg_unique_id = rest("/boards/id/${coreNode.id}/messages/id/${msg_non_unique_id}/id").value/>
