What is the equivalent to getLastInsertId() in Cakephp?

Question

If I do getLastInsertId() immediately after a save(), it works, but otherwise it does not. This is demonstrated in my controller:

f         


        

Answer 1

This will return last inserted id of last loaded model

$this->id;

This will return last inserted id of model with given model name

$this->Model->id;

This will return last inserted id of the model current model

CakePHP has two methods for getting the last inserted id: Model::getLastInsertID() and Model::getInsertID().

echo $this->ModelName->getInsertID();
echo $this->ModelName->getLastInsertID();
