[SOLVED] How to create a condition with a variable?

How to create a condition with a variable?

Is it possible to do something like that (doesn't work):

[{mysettings.id} in tree.rootLineIds]  

@import './TypoScript/'

[END]

Background: I have a Set Set, but want to use it only on specific page-Ids (and want to set these ID via Site Settings).

Thanks!

I'm using TYPO3 13

Solution

You can set condition as below in setup.typoscript file

[{$plugin.tx_myext.settings.myPageId} in tree.rootLineIds]
    @import 'EXT:my_ext/Configuration/TypoScript/'
[global]

assuming your Settings.yaml

plugin:
  my_ext:
    settings:
      myPageId: 123

settings.definitions.yaml

  plugin.tx_myext.settings.myPageId:
    category: MyExt.settings
    type: int
    label: 'Page of the MyPage'
    description: ''
    default: '0'

This will only include ".typoscript" files under directory "EXT:my_ext/Configuration/TypoScript/" when the condition matches
