の条件付きを置くことが可能かどうか尋ねたいと思いUPDATEます。まず、2つのテーブルがあります。

billing_records：

brecord_id (PK)
date_billed
monthly_rent
water
electricity
total_payable
status (paid/unpaid)

payment_records

payment_id (PK)
date
type_payment (cash/cheque/on_bank)
amount_payable
change
balance
cheque_number
bank_number
brecord_id (FK)

データベースにレコードを挿入するときに、コードを次のようにします。

IF balance==0 
     UPDATE status to 'paid' from billing_records TABLE
else
     UPDATE total_payable(of billing_records) = balance(of payment_records)

[送信]ボタンの実行中に、データを挿入するという2つのアクションがpayment_recordsありUPDATE billing_recordsます。支払いレコードにデータを挿入するのに問題はなく、billing_recordsを更新するだけです。

コントローラのこの行で問題が発生しています

//  4. call model to save input to database table

$this->m_account_statement->insertPayableRecords($data);

$this->m_account_statement->changeStatusToPaid($brecord_id);

これが私のコードです：

コントローラ：

public function managePayment($brecord_id=0){

    if($this->_submit_validate_payment($this->input->post('type_payment'))===FALSE){

        $row = $this->m_account_statement->payableRecord($brecord_id);

        $data['amountPayable'] = $row->result();
        $data['brecord_id'] = $brecord_id;

        return $this->load->view('admin/vrecord_payment',$data);

    } else {

        // 2. get the inputs    

        $data['payment_id'] = $this->input->post('payment_id');
        $data['amount_payable'] = $this->input->post('amount_payable');
        $data['amount_received'] = $this->input->post('amount_received');
        $data['type_payment'] = $this->input->post('type_payment');
        $data['cheque_number'] = $this->input->post('cheque_number');
        $data['bank_number'] = $this->input->post('bank_number');           
        $data['balance'] = $this->input->post('balance');       
        $data['change'] = $this->input->post('change');
        $data['brecord_id'] = $this->input->post('brecord_id');
        $data['date'] = $this->input->post('date_transaction');     

        //  4. call model to save input to database table

        $this->m_account_statement->insertPayableRecords($data);

        $this->m_account_statement->changeStatusToPaid($brecord_id);

        //  5. confirmation of registration

        $this->session->set_flashdata('message',' Successfully Record Payment');

        redirect('caccount_statement/displayTenants');

    }
}

モデル：

public function changeStatusToPaid($billing_id)
{
    $this->db->query("UPDATE billing_record SET status = 'paid' WHERE brecord_id = $billing_id");
}

public function insertPayableRecords ($data){

    if($this->db->insert('payment_record', $data)){
        return TRUE;
    }

    return FALSE;

}

このフローを使用できる条件を付けることができます。 

if balance==0 

//then fetch a record for status
//means run a query to get status

//now update

else 
// select some different values for update  
// now update query with fetched values
