我首先为这个问题道歉。我试图在 sale_price 部分填写数据，但仍然无效。
R1。我的 sale4.php 没问题。我用这个网址试过了，它有我需要的回报。
sale4.php?q=三星%20Galaxy%20S4
R2。我的 test.php 没问题。IT 返回/填充了从 sale4.php 获得的值
但在我的 cash.php 文件中，它运行良好。谁能告诉我什么是错的？屏幕截图：
解释：
- test.php：向 sale4.php 发送获取请求
- sale4.php 使用 $_GET var 返回销售价格。
- cash.php 获得的应用文件为test.php。我的文件如下-
// sale4.php
<?php
include('../_db/_con.php');
$m=$_GET['q'];
$que="SELECT `purchase_list`.`sale_price` , `purchase_list`.`pur_id`
FROM `purchase_list`
JOIN `item_info` ON `purchase_list`.`item_id` = `item_info`.`item_id`
WHERE `purchase_list`.`sale_price` <>0 AND `item_info`.`item_name` = '$m'";
$result = $mysqli->query($que);
$y=$result->fetch_array(MYSQLI_NUM);
echo $y['0'];
include('../_db/con_.php');
?>
