全部！
我不能改变我做过的表格。它在我的本地主机（xampp）上都能正常工作，但当我在服务器上上传时，它就不起作用了。我认为问题出在查询上，登录正在工作，所以我不认为是在数据库连接或获取数据上。我在else语句中得到了$message = "Error";，我还试着看看echo $titulli; echo $content;是否能使用该表单，它是否有效。我使用error_reporting(E_ALL & ~E_NOTICE);并收到这些问题（警告）
Warning: mysql_real_escape_string(): Access denied for user 'user'@'localhost' (using password: NO) in /home/user/public_html/test/admin-panel.php on line 12
Warning: mysql_real_escape_string(): A link to the server could not be established in /home/user/public_html/test/admin-panel.php on line 12
这是代码：
<?php
session_start();
include_once 'db_connect.php';
if(isset($_GET['update']) && !empty($_GET['update'])) {
$id = $_GET['update'];
$id1=mysql_real_escape_string($id);
$titulli = $_POST['emri'.$id];
$titulli1=mysql_real_escape_string($titulli);
$content = $_POST['mesazhi'.$id];
$content1=mysql_real_escape_string($content);
$date = date('Y-m-d H:i:s');
// echo $titulli;
// echo $content;
$update_query = "UPDATE `lagjja`.`content` SET `titulli` = '".$titulli1."', `content` = '".$content1."', `data` = '".$date."' WHERE `content` .`ID` = ".$id1;
$update_result = $mysqli->query($update_query);
if($update_result) {
$message = "you changes succeeded";
}
else {
$message = "Error";
//header('Location: index.php');
//die();
}
}
if (isset($_SESSION['id'])) {
$userId = $_SESSION['id'];
$username = $_SESSION['username'];
}
else {
echo "Your are not connected return to homepage";
header('refresh:2; url=index.php') ;
die();
}
?>

这是我的db_conncet.php
<?php
/* Konfigurimi i databazes */
define("HOST", "localhost");
define("USER", "laxhja");
define("PASSWORD", "password");
define("DATABASE", "laxhja");
define("SECURE", FALSE);
/* Lidhja me databaze */
$mysqli = new mysqli(HOST, USER, PASSWORD, DATABASE);
$mysqli->set_charset("utf8");
?>
<input type="submit" class="submit col-lg-12 col-md-12 col-sm-12 col-xs-12 btn btn-primary" value="Posto"></input>
将其更改为
<input type="submit" name="update" class="submit col-lg-12 col-md-12 col-sm-12 col-xs-12 btn btn-primary" value="Posto"/>
我通过将mysql_real_escape_string更改为mysqli_real_escape_string来解决它，并为它提供了2个参数。
像这样。
$con = mysqli_connect("localhost", "laxhja", "password", "laxhja");
if(isset($_GET['update']) && !empty($_GET['update'])) {
$id = $_GET['update'];
$id1=mysqli_real_escape_string($con, $id);
$titulli = $_POST['emri'.$id];
$titulli1=mysqli_real_escape_string($con, $titulli);
$content = $_POST['mesazhi'.$id];
$content1=mysqli_real_escape_string($con, $content);
$date = date('Y-m-d H:i:s');...
