Question

当用户从我的网站删除项目时，一个简单的查询会从数据库中删除附加的记录，并且用户将被带到主页，这将在页面顶部显示一个栏目＆＃34;项目已删除＆＃ 34;我这样做是因为有一个GET＆＃39; err＆＃39;在URL中，所以当错误设置时，它旁边的数字定义应该在页面顶部显示什么警报。

我遇到的问题是，当运行此php脚本时，将显示第4个警报而不是第8个警报。

PHP：

if (mysqli_query($conn, "DELETE FROM projects WHERE id='$del' AND user_id ='$user_id'")) {
        if (mysqli_query($conn, "DELETE FROM refs WHERE project_id='$del' AND user_id ='$user_id'")) {
            setcookie("project_cookie", 0);
            header("Location: index.php/?del=8");
        }
    }

Alerts.php（附在头文件的顶部）：

if (isset($_GET['err'])) {
    $err = $_GET['err'];
    $type = "err";

    if ($err == "1") { $alert = "Incorrect Email or Password"; }
    elseif ($err == "2") { $alert = "Email address already exists"; }
    elseif ($err == "3") { $alert = "All fields require values"; }
    elseif ($err == "4") { $alert = "Reference Deleted"; }
    elseif ($err == "5") { $alert = '<a href="http://bradleycousins.co.uk/?auth=signup">' . '<b>' . "Signup"  . '</b>' . '</a>'. " " . "to create and save references"; }
    elseif ($err == "6") { $alert = "You can only have 8 projects"; }
    elseif ($err == "7") { $alert = "Select a project on the left hand side first"; }
    elseif ($err == "8") { $alert = "You have deleted a project"; }

}

我已经查看了很长一段时间，并且不知道为什么第四个警报显示而不是运行PHP删除脚本时的第8个警告。

Answer 1

更改，

header("Location: index.php/?err=8");

要，

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

由于，

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

不
