Question

这是我正在研究的一个学校项目，我现在已经调试了6个小时并且有点沮丧。

我有一个页面，它在HTML输入标记中显示表格数据，同时，我点击更新链接时对其进行了更新查询。但到目前为止它还没有发挥作用。

<?php
    include_once 'admindbconnect.php';

    if (isset($_GET['delete'])) {
        $query = mysqli_query($dbcon, "DELETE FROM userstable WHERE userID=".$_GET['delete']);
        header("Location: $_SERVER[PHP_SELF]");
    }

    if(isset($_POST['edit'])) {
        $query = $dbcon->query("UPDATE userstable SET username='".$_POST['viewUsername']."', userPassword='".$_POST['viewPassword']."', userEmail='".$_POST['viewEmail']."' WHERE id=".$_GET['edit']);
        mysqli_query($dbcon, $query);
        header("Location: admin.php");
    }

?>

编辑：有人标记这是重复的＆＃34;如何在不同环境中获取mysqli错误？＆＃34;但这不是我的问题，我的问题是它为什么不更新。

Mysqli更新查询不起作用，没有错误
