PIDinRootline for TCA mm relation for 'foreign_table_where'

问题

I have an extension (Typo3 8.7.4) with categories in mm relation. The categories are saved in different pages. So i want to select only categories who are saved in the tree of a certain page and the subpages of this certain page. Is there a marker like the condition in typoscript "PIDinRootline" for selectin entries for foreign_table_where in TCA?

回答1:

rootUid ist the correct treeConfig

回答2:

The TCA foreign_table_where is documented on this page: https://docs.typo3.org/typo3cms/TCAReference/ColumnsConfig/Type/Select.html# An here you can find an explanation of the possible markers you can use in the query: https://docs.typo3.org/typo3cms/TCAReference/ColumnsConfig/Type/Select.html#foreign-table-where

E.g. you can use ###CURRENT_PID### to fetch records form the current page.

Try to use below typoscript.

This checks if one of the figures in "pages-uidl" is a PID (pages-uid) in the rootline:

[PIDinRootline = pages-uid, pages-uid, ...]

Do the same as PIDinRootline, except the current page-uid is excluded from check.

[PIDupinRootline = pages-uid, pages-uid, ...]
