这是我的编辑页面代码，当用户单击编辑时，他将被重定向到此页面并且它仍然可以工作，但是在我单击更新按钮编辑内容之后，即使它之前完美工作，也没有发生任何事情，现在我已经尝试了一切但是这个按钮没有更新我的数据，甚至根本没有响应：
<?php
$eid = $_GET['id'];
$con = mysqli_connect("localhost","root","","news") or die("Connection Failed!");
$sql = "SELECT * From content where pid = {$eid}";
$result = mysqli_query($con, $sql) or die("Query Failed!");
$t = mysqli_fetch_assoc($result);
?>
<html>
<head>
<title>Edit</title>
</head>
<link rel="stylesheet" href="bootstrap\css\bootstrap.min.css">
<body>
<!-- PHP: Sending updated data to server -->
<?php
$article = '';
if(isset($_POST['button'])){
$article = isset($_POST['edit-box']) ? $_POST['edit-box'] : ''; //here you will get value of textarea
$sql1 = "UPDATE content SET article = '{$article}' WHERE pid = $eid";
$result1 = mysqli_query($con, $sql1);
if($result1){
header('Location: http://localhost/preply/news-site');
}else{
echo "Query Failed!";
}
}
?>
<!-- HTML -->
<div class="container mt-2">
