Question

I am developing an extension that allows admins to save stuff to the database.

And I want that each instance of the extension should have it’s own Id in the database.
Is there some way to get the tt_content uid (which I guess is the extension instance Id) in the extension php.

Answer 1

You fetch all tt_content’s data in array:

$this->cObj->data

ie:

$uidOfCE = $this->cObj->data['uid'];

If you’re using Extbase of course you need to get the content object first, ie:

$this->contentObj = $this->configurationManager->getContentObject();
debug($this->contentObj->data, "current tt_content's data");
