Answer 1

All the last_insert_id functions (be they PHP wrappers or the native mySQL one) typically refer to the last ID created using the current database connection. The last login was probably not created during the same request you are showing the table in, so this method won't work for you.

Use a normal SELECT to find out the newest login instead - e.g. by using ORDER by creationtime DESC LIMIT 1.

Answer 2

Pekka's answer is good for common. But if you want to do that action in Yii Framework, try this:

$myModel = new $model;
$model -> savel(false);
echo $model->primaryKey; // Prints the last id.

Or you may try this too for general solution:

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

$max = Yii::app()->db->createCommand()->select('max(id) as max')->from('TABLENAME')->queryScalar();

Just add one to get the next.
