Getting insert id with insert PDO MySQL

Im getting to grips with the basics of PDO.

However Im trying to get the id of the inserted row, Im using:

$query = $system->db->prepare(\"INSE         


        

Answer 1

Pay attention when using transactions.

If you call lastInsertedId after you call commit, lastInsertedId will return 0 instead of the id. Call lastInsertedId right after execute, but before commit.

$this->db->beginTransaction();
$this->stmt->execute();
$id = $this->db->lastInsertId();
$this->db->commit();
