PHP和mysql問題,更新兩個表,並通過一個按鈕插入兩個表

[英]php and mysql problems with updating two tables, and inserting into two tables with one button

這是我的結帳頁面的一些代碼。 我是php新手,這是我的第一學期,但我仍在努力。 此頁面收集添加到購物車的訂單,並完美顯示和匯總訂單。 這是我的問題。

有時會有OrderIn產品,可能不存在或不止其中之一,也可能存在OrderOut產品,或者不存在。 我知道很復雜。 我可能正在嘗試做太多事情。 當我按“付款此發票”按鈕時,我想收集(無論是多少還是哪種)訂單ID(出庫或入庫),並將“已支付的訂單ID”設置為“是”,然后將OrderId插入相應的發票invoice_in或invoice_out,並設置為否。

是否可以,將第一個產品OrderId_in更改為yes,現在我收到一個MySQL錯誤“ SQL語法有誤;請查看與您的MySQL服務器版本相對應的手冊以獲取正確的語法,在第2行的'75 .18','No')'附近使用。” 我可以在這里使用一些指示。

您的代碼有些錯誤。

VALUES ('$user_id', '$orderIn_id  '$invoiceIn_total',
                                ^^

缺少引號和逗號

VALUES ('$user_id', '$orderIn_id',  '$invoiceIn_total',

同樣的事情

VALUES ('$user_id', '$orderOut_total  '$invoiceOut_total',
                                    ^^

VALUES ('$user_id', '$orderOut_total', '$invoiceOut_total',

這些是SQL錯誤的來源。

發布的代碼中未定義$orderOut_total

另外,根據您的評論:

“弗雷德,我發現了為什么我的OrderOut_id沒有被填充,我發現了一個語法錯誤,我在創建和定義變量時沒有使用正確的$ row2來抓取它。盡管我尚未測試,但它現在適用於OrderIn和OrderOut。多訂單。但是,由於弗雷德(Fred)的幫助,我找到了確切的語法錯誤。

  • 最終成為解決問題的方法。

我必須注意 ,您當前的代碼可以進行SQL注入 使用預處理語句或將PDO與預處理語句結合 使用起來更加安全


錯誤報告添加到文件頂部,這將有助於發現錯誤。

<?php 
error_reporting(E_ALL);
ini_set('display_errors', 1);

// rest of your code

旁注:錯誤報告僅應在登台進行,而不應在生產過程中進行。
