我找不到解决这个问题的方法。我有大问题,我不知道解决了,我会等待解决方案,谢谢。是域名的问题吗?

<?php

session_start();

require_once("../Connections/Store.php");

if(isset($_GET['page'])){

    $pages = array("products","cart");


if(in_array($_GET['page'],$pages)){


        $page=$_GET['page'];

        }else {

            $page="products";


    }

}else {



    $page="products";

}


?>

您的查询无法mysql_error用于查看错误

$query=mysql_query($sql) or die(mysql_error());

.并从这里移除

$sql .="SELECT * FROM products WHERE pro_id IN (";
    ^^

注意: 请不要mysql_*在新代码中使用函数。它们不再被维护并被正式弃用。看到红框了吗?改为了解准备好的语句,并使用PDOMySQLi -本文将帮助您决定使用哪个。如果您选择 PDO,这里有一个很好的教程
