Question

我有一个只读文本框，它从数据库sales表中检索最大收据号为否。

<input name="txtReceiptNo" type="text" id="txtReceiptNo" size="10" value="<?php 
$receiptNo = mysqli_fetch_row(mysqli_query($connection,"SELECT max(sales_id)+1 FROM sales")); echo $receiptNo[0];?>" readonly />

当我尝试将其发送到数据库时，会出错。

#1054 - Unknown column 'receipt_no' in 'field list'

（是的，我知道这是不正确的，但我怎么能纠正这个？）

SQL查询：

INSERT INTO sales(cus_id,item_id,stock_id,receipt_no,qty,unit_price,discount,amount,user_id,purchase_id) 
SELECT C.cus_id, I.item_id, S.stock_id, receipt_no='$receipt_no',ST.qty, ST.unit_price, ST.discount, ST.amount, U.id, P.purchase_id 
FROM customers C, items I, stock S, sales_temp ST, users U, purchase_items P
WHERE ST.staff='$user' AND 
C.customer_name='$customer' AND 
I.item_name=ST.item_name AND 
S.stock_code=ST.stock_code AND 
ST.purchase_id=P.purchase_id

编辑代码：

INSERT INTO sales(cus_id,item_id,stock_id,receipt_no,qty,unit_price,discount,amount,user_id,purchase_id) 
SELECT C.cus_id, I.item_id, S.stock_id, receipt_no='$receiptNo',ST.qty, ST.unit_price, ST.discount, ST.amount, U.id, P.purchase_id 
FROM customers C, items I, stock S, sales_temp ST, users U, purchase_items P
WHERE ST.staff='$user' AND 
C.customer_name='$customer' AND 
I.item_name=ST.item_name AND 
S.stock_code=ST.stock_code AND 
ST.purchase_id=P.purchase_id

我已经解决了上述问题。

编辑后的代码如下：

INSERT INTO sales(cus_id,item_id,stock_id,receipt_no,qty,unit_price,amount,user_id,purchase_id) 
SELECT C.cus_id, I.item_id, S.stock_id, $receipt_no, ST.qty, ST.unit_price, ST.amount, U.id, P.purchase_id 
FROM customers C, items I, stock S, sales_temp ST, users U, purchase_items P 
WHERE ST.staff='$user' 
AND C.customer_name='$customer' 
AND I.item_name=ST.item_name 
AND S.stock_code=ST.stock_code 
AND ST.purchase_id=P.purchase_id

将从数据库中检索的表单值再次插入到MySQL数据库中
