我正在编写一个库存管理系统，我想弹出一个包含 sql 查询结果值的框，如果可能的话，直接从此弹出窗口打印。下面是我的表格。所有值都会相应更新。
该表为 Stock_details，其中包含列 id、stock_id、stock_name、stock_quantity、supplier_id、company_price、sales_price、category、serial_no、bar_code、po_number、location、user_name、do_number、status、date、kerry_barcode。
当我提交新的购买时，它将使用 add_purchase 表单上的值更新数据库，但不会弹出包含 kerry_barcode 值的框。在这里我还想有一个打印按钮，这样我就可以打印生成的条形码。
例如:
Kerry_barcode = stock_id + category + location
即
kerry_barcode = PICT43 - Desktop - MY-JHB-KGBS
我在我的数据库上运行了以下查询并填充了它；
SELECT CONCAT(stock_id, ' - ', category, ' - ', location) AS kerry_barcode FROM stock_details.
我尝试过使用;
<td>
<?php
$kerrybarcode = $db->query("SELECT CONCAT(stock_id, ' - ', category, ' - ', location) AS kerry_barcode FROM stock_details ");
?>
<td><span class="man">*</span>Kerry Barcode:</td>
<td><input name="kerrybarcode" type="text" id="kerrybarcode" maxlength="400"
class="round default-width-input"
value="<?php echo isset($kerrybarcode) ? $kerrybarcode : ''; ?>"/></td>
它成功更新数据库，但 Kerry_username 未更新。
我需要帮助才能正确执行此查询，并弹出一个框，其中包含根据上次更新的 ID 和打印按钮填充的值。
我正在使用最新的 mysql maria db 和来自 xampp 的 php myadmin。
以下是我的 add_purchase 页面。

最佳答案
解决了。
刚刚添加了此 SELECT CONCAT(stock_id, ' - ', Category, ' - ', location ，以将多个列添加到 kerry_barcode
$db->query("insert into stock_details(stock_id,stock_name,supplier_id,company_price,selling_price,category,user_name,location,serial_no,po_number,bar_code,do_number,status,kerry_barcode) values('$stockid','$name','$supplier','$cost','$sell','$category','$username','$location','$serialno','$ponumber','$barcode','$donumber','$status',CONCAT('$stockid',' - ','$name',' - ','$location'))")) {
弹出和打印 我创建了一个页面来查询上次更新的对象并添加了 printpage()
