$this->db->trans_start();
$fldCompanyID = getCoompanyByStringID($fldCompanyStringID)->fldCompanyID;
/* Insert User */
$data = array(
'fldUserFName' => $this->input->post('fldUserFName'),
'fldUserBankAccountNumber' => $this->input->post('fldUserBankAccountNumber')
);
$this->db->insert('tblUser', $data)
$insert_id = $this->db->insert_id();
/* Insert Work History */
$data2 = array(
'userID' => $insert_id,
'fldWorkHistoryCompanyName' => $this->input->post('fldWorkHistoryCompanyName')
);
$this->db->insert('tblWorkHistory', $data2)
/* Manage Transaction */
$this->db->trans_complete();
if ($this->db->trans_status() === FALSE){
$this->session->set_flashdata('error_msg', 'Failed, please try again');
}else{

$this->db->insert_id() is used to get the last insert auto increment id data.
$this->db->insert('tblUser', $data);
$insert_id = $this->db->insert_id();
if($insert_id) {
$data2 = array(
'userID' => $insert_id,
'fldWorkHistoryCompanyName' => $this->input->post('fldWorkHistoryCompanyName')
);
if ($this->db->insert(' tblWorkHistory', $data2)) {
$this->session->set_flashdata('success_msg', 'New Employee is inserted');
}
} else {
$this->session->set_flashdata('error_msg', 'Something went wrong');
}
