Child Page Count from Specific Parent Page by ID

[becki.marsh]

I have the ability to count child pages of the current page via the code below. I'd now like to amend the code so that I can specify a specific page to count from.

#set($pageCount=0)

#foreach ($child in $content.children)
    #set($pageCount = $pageCount + 1)
#end

$pageCount

As user macros can use a bunch of Velocity context objects including those in the default Velocity context, you should have access to the `pageManager`.

Reference: https://docs.atlassian.com/ConfluenceServer/javadoc/8.7.1/com/atlassian/confluence/pages/PageManager.html

Using that, something like would work:

#set($pageCount=0)

#set($parentPage = $pageManager.getPage(123)) ## 123 is the ID of the specific page
#foreach ($child in $parentPage.children)
    #set($pageCount = $pageCount + 1)
#end

$pageCount
