我在这里做错了什么！我想显示与特定客户端 ID 关联的所有数据

EX用户输入“2”

将显示所有具有 client_id "2" 的行

<?php

if($_POST['submit'] == "submit"){
   $username="xxx_admin";
   $password="xxx";
   $database="xxx_database";

//connect to mysql server
                $mysqli = new mysqli("localhost", $username, $password, $database);

                                        //check if any connection error was encountered
                                        if(mysqli_connect_errno()) {
                                            printf("Connect failed: %s\n", mysqli_connect_error());
                                            exit;
                                        }   
   $client_id = $_POST['client_id'];
   echo $client_id;
  $query = "select * from messages where client_id='$client_id'";
  $result = mysqli_query($query);
  $class_p = "timeling";
  $clid_p = "oldupdate";
  echo "<ol id=".$clid_p." class=".$class_p.">";echo $row->message;
                                        while ($row = $result->fetch_object())
                                        {
                                                // set up a row for each record
                                                echo "<li>";
                                                echo $row->message;
                                                echo "<br>" . $row->date_post;
                                                echo "</li>";
                                        }

    echo "</ol>";

     $mysqli->close();
}

以下应该工作

while ($row = mysqli_fetch_object($result))
{
    // set up a row for each record
    echo "<li>";
    echo $row->message;
    echo "<br>" . $row->date_post;
    echo "</li>";
}
