Question

我已经使用php（home.php）创建了一个评论页面，用户会在页面上发布评论但是当页面刷新时，所有以前的评论都会消失。有谁知道如何让评论留在页面上？也有人知道如何使他们登录的用户ID /名称与时间戳一起显示（添加评论时已经存在）??

<?php
session_start();
require_once('recaptcha/recaptchalib.php'); 
if (!isset($_SESSION['logged'])){
$_SESSION = array();
header('location: home_start.php'); //your login form
require_once("functions.php");
include_once("home_start.php");
}

//EXISTING DATABASE CONNECTION CODE
$db_hostname = 'xxxx';
$db_database = 'xxxx'; //'Your database name' 
$db_username = 'xxxxx'; //'your username'; 
$db_password = 'xxxx'; //'Your password'; 
$db_status = 'not initialised';
$str_result = ' ';
$str_options = ' ';
$db_server = mysqli_connect($db_hostname, $db_username, $db_password);
$db_status = "connected";
$db_select = mysqli_select_db($db_server, $db_database);
require_once("cleanstring.php");
 if (!$db_server){
die("Unable to connect to MySQL: " . mysqli_connect_error($db_server)); 
$db_status = "not connected";
}else{ 
   //NEW SUBMISSION HANDLING CODE HERE
    if(isset($_POST['submit'])) {
              $privatekey = "6Lem4-gSAAAAADsaa9KXlzSAhLs8Ztp83Lt-x1kn"; 
              $resp = recaptcha_check_answer ($privatekey,
                            $_SERVER["REMOTE_ADDR"],
                            $_POST["recaptcha_challenge_field"],
                            $_POST["recaptcha_response_field"]);

         if (!$resp->is_valid) {
                $message = "The reCAPTCHA wasn't entered correctly. Go back and try it again. (reCAPTCHA said: " . $resp->error . ")";
                        //Print out existing comment

                        } else {
                            $userID = $_SESSION['userID'];
                            $comment = clean_string($db_server, $_POST['comment']);
                            if ($comment != '') {
                            $query2 = "INSERT INTO comments (comment) VALUES ('$comment')";
                                    mysqli_select_db($db_server, $db_database);
                                    mysqli_query($db_server, $query2) or
                                                 die("Insert failed: " . mysqli_error($db_server));

                                                            $message = "Thanks for your comment!";
                            }
                            $query3 = "SELECT * FROM comments";
                            $result3 = mysqli_query($db_server, $query3);
                            if (!$result3) die("Database access failed: " . mysqli_error($db_server)); 
                            while($array = mysqli_fetch_array($result3)){
                                     $comments = date('d/m/Y', strtotime($array['commDate'])) . "<p>" . $array['comment'] . "</p><br/>";
                        }
                             mysqli_free_result($result3);
