[TYPO3-dev] get the pid of the backend page

[Tudor]

Hi,

How can i get the "pid" of the page where i insert my new pugin records?
I want to use the pid for 'foreign_table_where'.

'config' => array (
                 'type' => 'select',
                 'foreign_table' => 'tx_petfoodsearch_category_items',
                 'foreign_table_where' => '....'

Thx
