在另一個表中刪除和插入新數據后更新一個表

Question

我想要：

1. 在表tbl_cost_sharing中刪除和插入數據

和

2. 單擊編輯按鈕時更新表tbl_payment_request 。

我在下面編寫的代碼只是在做 (1) 即刪除和插入表tbl_cost_sharing中的數據而不是 (2) 即更新表tbl_payment_request 。 當我運行它時，代碼沒有顯示任何錯誤。

    if($_POST['btn_action'] == 'Edit')
    {
        $delete_query =
            "
                DELETE FROM
                  tbl_cost_sharing
                WHERE
                  payment_request_id = '".$_POST["payment_request_id"]."'
            "
        ;
        $statement = $connect->prepare($delete_query);
        $statement->execute();
        $delete_result = $statement->fetchAll();

        if(isset($delete_result))
        {

            $total_amount = 0;
            for($count = 0; $count<count($_POST["protocol_id"]); $count++)

Answer 1

我發現了我在哪里犯了錯誤；

我不應該把''放在SET字段上，例如

            $update_query =
                "
                    UPDATE
                        tbl_payment_request
                    SET
                        'department_id'         = :department_id,
                        'payee_id'              = :payee_id,

相反，它應該像下面這樣：

            $update_query =
                "
                    UPDATE
                        tbl_payment_request
                    SET
                        department_id         = :department_id,
                        payee_id              = :payee_id,

我也離開了,在:payment_request_total和:payment_details如下：

            $update_query =
                "
                    UPDATE
                        tbl_payment_request
                    SET
                        'department_id'         = :department_id,
                        'payee_id'              = :payee_id,
                        'payment_type_id'       = :payment_type_id,
                        'currency_type_id'      = :currency_type_id,
                        'payment_details'       = :payment_details
                        'payment_request_total' = :payment_request_total
