您可以在交易中完成。如果您收到任何错误，请告诉我

public function delete($email, id_camion) {
    $this->db->trans_start();
    $this->db->delete('transporteur', array('email' => $email));
    $this->db->where('cid', $id_camion); 
    $this->db->update('camion', array('etat' => 0));
    $this->db->trans_complete();
    if ($this->db->trans_status() === FALSE) {
        $this->db->trans_rollback();
    }
    else {
        $this->db->trans_commit();
    }
}
