Macro to count child pages of specified page

Gareth Edwards4

Hi. I'm trying to write a user macro that will accept a page id and give a count of the number of child pages that page has.

I get that I can do this for the current page using $content.getChildren().size(), but I'm getting tangled up trying to do this for any specified page. Would someone be able to point me in the right direction?

Hi Gareth,

You can get do it like the following:

#set($pageManager=$containerContext.getComponent('pageManager')) 
#set($spacekey='TEST')
#set($pagetitle='this is just a test')

#set($page=$pageManager.getPage($spacekey,$pagetitle))
$page.getChildren().size()

Of course, you can always change the above code so that the $spacekey and $pagetitle are the macro's parameters.

Hope it helps!

That's perfect, thank you Amalia!

Can you help me with how it would ook like with params, currently the following is not working:

#set($pageManager=$containerContext.getComponent('pageManager'))

##@param ($spacekey)

##@param ($pagetitle)

#set($page=$pageManager.getPage($spacekey,$pagetitle))<br>$page.getChildren().size()

You have defined the parameters in an incorrect way. Please have a look at this documentation

as well as some examples:

Thanks, but I still can't make it work. it shows me : <br>$page.getChildren().size()

THis is the macro:

## set($pageManager=$containerContext.getComponent('pageManager'))

## @param space:title=SpaceKey| type=spacekey|desc=Space Key|required=true|multiple=false

## @param page:title=PageTitle| type=confluence-content|desc=Page Title|required=true|multiple=false

## set($page=$pageManager.getPage($paramspace,$parampage))

<br>$page.getChildren().size()

Any more pointers...please

I've tied following all of the above code, and even browsed the API looking for answers. This is extremely frustrating, as all I seem to get out is the string "<br>$page.getChildren().size()" instead of the value its supposed to hold. Can anyone shed some light on this? I can get a number if I manually specify the pageID in ## set($page=$pageManager.getPage($paramspace,$parampage)) but that's not a good way to build this.

its a bit outdated, but you had a space too much in the space parameter, right before you define type. That code is working for me: #set($pageManager=$containerContext.getComponent('pageManager')) ## @param spacekey:title=SpaceKey|type=spacekey|desc=Space Key|required=true|multiple=false ## @param pagetitle:title=Parent|type=confluence-content|required=true|desc=Select a page which children to count #set($page=$pageManager.getPage($paramspacekey,$parampagetitle)) $page.getChildren().size()

For anyone finding this topic.. this worked for me. Seems functions cannot be chained:

```

## Macro title: childcount
## Macro has a body: N
## Body processing: Selected body processing option
## Output: Selected output option

## Developed by: My Name

## @noparams

#set($pageManager=$containerContext.getComponent('pageManager'))
#set($currentPage=$pageManager.getPage($space.key, $content.title))
#set($children=$currentPage.getChildren())
#set($count=$children.size())

$count

```
