我目前正在为我的私有服务器建立数据库，但是我的代码有问题：
我的提交按钮不起作用/将查询发送到数据库。 也许您可以给我一些根本原因的提示。
这是我的代码：
<?php
session_start();
//error_reporting(0);
ini_set('display_errors',1);
error_reporting(E_ALL);
require_once ('includes/config.php');
if(strlen($_SESSION['alogin'])==0)
{
header('location:index.php');
}
else{
if(isset($_GET['edit']))
{
$editid=$_GET['edit'];
$sql = "SELECT * from server where id = :editid";
$query = $dbh -> prepare($sql);
$query->bindParam(':editid',$editid,PDO::PARAM_INT);
$query->execute();
$result=$query->fetch(PDO::FETCH_OBJ);
$cnt=1;
}
if(isset($_POST['submit']))
{
$host = $_POST['host'];
$hostport = $_POST['hostport'];
$serverusr = $_POST['serverusr'];
$serverpwd = $_POST['serverpwd'];
//$id=$_POST['id'];
//$host=$_POST['host'];
//$hostport=$_POST['hostport'];
//$serverusr=$_POST['serverusr'];
//$serverpwd=$_POST['serverpwd'];
//$designation=$_POST['designation'];
//$editid=$_POST['id'];
//$image=$_POST['image'];
$sql = "UPDATE server SET 'host'=:host, 'hostport'=:hostport, 'serverusr'=:serverusr,'serverpwd'=:serverpwd WHERE 'id'=:editid";
//$sql = "UPDATE `server` SET `host` = '$host', `hostport` = '$hostport', `serverusr` = '$serverusr', `serverpwd` = '$serverpwd' WHERE `server`.`id` = $editid";
//$sql= mysql_query("ALTER server SET host = '$host', 'hostport' = '$hostport', serverusr = '$serverusr', serverpwd = '$serverpwd' WHERE id = '$idedit'");
//$sql = "UPDATE server SET hostport = '$hostport' , host = '$host' , serverusr = '$serverusr' , serverpwd = '$serverpwd' where id = '1'";
//$sql = "UPDATE server SET (host,hostport,serverusr,serverpwd) (:host, :hostport, :serverusr, :serverpwd) ";
$query= $dbh -> prepare($sql);
$query-> bindParam(':host', $host, PDO::PARAM_STR);
$query-> bindParam(':hostport', $hostport, PDO::PARAM_STR);
$query-> bindParam(':serverusr', $serverusr, PDO::PARAM_STR);
$query-> bindParam(':serverpwd', $serverpwd, PDO::PARAM_STR);
$query->execute();
//$query->execute(array(":host"=>$host,":hostport"=>$hostport,":serverusr"=>$serverusr,":serverpwd"=>$serverpwd,":editid"=>$editid));
$result=$query->fetch(PDO::FETCH_OBJ);
$msg="server Host successfully updated!";
$error="";
//echo $sql;
exit
}
}

如您所见，我尝试了几次查询...但没有任何效果。 我有一个名为configuration.php的单独站点，可以在其中将服务器成功添加到数据库中。
