Writing a TYPO3 extension, I needed to allow records of a certain table to be created on TYPO3's root page (pid=0). While the solution is easy, it took me a while to find it.
In ext_tables.php, add a rootLevel setting to your table's ctrl array:
$TCA['static_countries'] = array( 'ctrl' => array( 'title' => 'Countries', 'label' => 'cn_short_en', 'rootLevel' => 1, ...
TYPO3 allows three settings here: 0, 1 and -1, which are described in the Core API documentation:
- rootLevel = 0
- Records may only exist in the page tree, not in the root.
- rootLevel = 1
- Records may only exist in the root, not on the page tree. Note that only admins may edit records in the root page.
- rootLevel = -1
- Records may exist in both the root and the page tree.
