Answer 1

You can get the last inserted ID like this:

Yii::app()->db->getLastInsertId();

See the Yii documentation for more information.

Answer 2

如果您的目标是获取分配给您刚刚保存的模型的ID，那么在执行$model->save() ，只需执行$model->id即可将其恢复。

Answer 3

如果$model->id不起作用，则使用Yii::app()->db->getLastInsertId()或getPrimaryKey() 。

Answer 4

you can also get the last inserted id of another model.

$std_id = Students::model()->findAll(array('order' => 'admission_no DESC','limit' => 1));

            foreach($std_id as $f) {

                echo  "Last Inserted Admission No:".$f['admission_no'];
                }

or

you can last inserted id in the same model

Yii::app()->db->getLastInsertID();
