Question

此表显示了用户在我的网站上添加的所有“景点” - 一个可以记录的库。他们可以通过点击'empty_trash-26.png'图像删除任何这些'景点'。哪个链接到drop_attraction.php

我的问题是，当用户去删除他们已添加的“吸引力”时，它会删除添加到网站/数据库中的最新“吸引力”。我假设在while循环中，$ _SESSION ['attraction_id']每次被最新实体覆盖。

有谁知道我怎么能阻止这个？ - 所以他们可以删除他们想要的任何东西，而不仅仅是最新的！

// Connects to my Database
include "Config.php";
$dataA = mysql_query("SELECT * FROM Attractions WHERE user_id = ".$_SESSION['id']."") or die(mysql_error()); 

// HEADER OF TABLE              
Print "<table id="."box-table-a"." summary="."Deals".">";
Print "<thead>";
Print "<tr>";
Print "<th scope="."col".">Categories</th>";
Print "<th scope="."col".">Item Name</th>";
        Print "<th scope="."col".">Price</th>";
        Print "<th scope="."col"."> </th>";
    Print "</tr>";
Print "</thead>";

// ATTRACTIONS  
while($infoA = mysql_fetch_array($dataA)) 
{ 

 Print "<tbody>";
    Print "<tr>";
    Print "<td>"."Attractions"."</td>";
        Print "<td>".$infoA['attraction_name'] . "</td>";
        Print "<td>".$infoA['attraction_price'] . " </td>";

$_SESSION['attraction_id'] = $infoA['id'];
$_SESSION['attraction_name'] = $infoA['attraction_name'];
$_SESSION['attraction_price'] = $infoA['attraction_price'];


        Print "<td><a href="."drop_attraction.php"."> <img src="."images/empty_trash-26.png"." width="."20"." height="."20"."></a></td>";
    Print "</tr>";
Print "</tbody>";
} 
Print "</table>";

下面是drop_attraction.php页面 - 一旦点击'empty_trash-26.png'，php页面将重定向到此页面，因此可以在我的数据库的'Attractions'表中删除该行。完成后，将其直接链接回“dashboard-library.php”页面（上面显示的代码）

include "config.php";
mysql_query("DELETE FROM Attractions WHERE id=".$_SESSION['attraction_id']."");
header('Location: /dashboard-library.php');

您的带有景点表的页面应该将ID传递到放置景点页面：

Print "<td><a href="."drop_attraction.php?id=".$infoA['id']."> <img src="."images/empty_trash-26.png"." width="."20"." height="."20"."></a></td>";

drop_attractions.php

include "config.php";
mysql_query("DELETE FROM Attractions WHERE id=".mysql_real_escape_string($_GET['id']));
header('Location: /dashboard-library.php');

会话ID在while循环中被覆盖。怎么预防呢？
