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

CakePHP has two methods for getting the last inserted id: Model::getLastInsertID() and Model::getInsertID(). Actually these methods are identical so it really doesn't matter which method you use.

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

This methods can be found in cake/libs/model/model.php on line 2768

Answer 2

Below are the options:

echo $this->Registration->id;

echo $this->Registration->getInsertID();

echo $this->Registration->getLastInsertId();

Here, you can replace Registration with your model name.

You can get last inseted id with many ways.Like Model name is User so best way to fetch the last inserted id is

$this->User->id; // For User Model

You can also use Model function but below code will return last inserted id of model with given model name for this example it will return User model data

$this->User->getLastInsertId();
$this->User->getInsertID();

Answer 4

Actually you are using the getLastInsertId or getInsertId in a wrong manner. getLastInsertId() is meant to work only after save() method. It will even not work after a manual insert, as cake engine is storing the mysql_insert_id under $this->_insertID inside the save method which can be retrieved via the getLastInsertId or getInsertId. Now in your case

$this->Model->id

OR

$this->Model->find('first',array('order'=>'id DESC')) 

Will do.

Answer 5

$Machinedispatch = 
   $this->Machinedispatch->find('first',array('order'=>array('Machinedispatch.id DESC')));

Simplest way of finding last inserted row. For me getLastInsertId() this not works.

Answer 6

Just use:

$this->Model->id;
