Getting tag from URL

We are trying to edit the TagViewPage and need to know which tag is currently being displayed with Freemarker. I tried every attribute or parameter call I could find but to no success.

 

Currently, my work around is:

<#assign url = http.request.url />
<#assign urlSections = url?split("/") />
<#if urlSections?size gte 5>
<#assign tag = urlSections[5] />
<#else>
<#assign tag = "" />
</#if>

 

(I'm using 5 since the URL will end up being this [for now]: https:(0)/(1)/(2)domain.com/(3)t5/(4)tag/(5)TAG_NAME/tg-p/board-id/BOARD_ID)

 

Anyove have a better idea or know of a call that will work? Thanks.

    I think you're workaround is good, one thing you might consider changing is instead of relying on the length of the URL sections and the location of the tag-value section within the array, you could instead rely on the order. In the case of the TagViewPage the URL section representing the tag value will always be preceded by a URL section called "tag". The creates a key/value pair like this: /tag/<tag-value>. So the code might look something like this:

     

    <#assign urlSections = http.request.url?split("/") />
<#assign tag = "" /> 

<#list urlSections as urlSection>
    <#if urlSection_index gt 0 && urlSections[urlSection_index - 1] == "tag">        
        <#assign tag = urlSection />
    </#if>
</#list>

    Our approach was the create a function to grab the tag (if available)

     

    <#function getTag>
  <#assign tag = webuisupport.path.parameters.name.get("tag-id")! />

  <#if tag??>
    <#return tag.tagText! />
  <#else>
    <#return false />
  </#if>
</#function>
