隔离结果时显示其他表单数据

Question

我有一个表格，可以将调查结果显示到网页中。目前，当用户单击“查看此处”时，它会将他们带到该 ID 的单独条目。单击它时，我希望它还显示其他结果（也是来自同一数据库的部分结果）。

知道我是怎么做到的吗？澄清一下，在单击 ID 以挑出该条目之前，它不应该显示 - 否则它会一个接一个地完整显示它们。

<?php

try {
    $handler = new PDO('mysql:host=localhost;dbname=***', '***', '***');
    $handler->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch(PDOException $e) {
    echo $e->getMessage();
    die();
  }
class guestquestionnaireEntry {
    public $id, $date_submitted, 
        $entry;

        public function __construct()
    {

$this->entry = "

        <table border='1' align='center'>

                 <tr class='tablelist' style='font-size: 8pt;' ><td width='5%' colspan='2'>{$this->ID}</td><td width='40%' colspan='2'><b>Date Received: </b>{$this->date_submitted}</td><td width='45%' colspan='2'>{$this->name}</td><td width='10%'><a href=\"?ID={$this->ID}\">View here</a> </td></tr>

        </table>

";

    }

}

        SELECT DATE_FORMAT(date_submitted, '%m/%d/%Y') AS date_submitted FROM guestquestionnaire


// Checks if the submitted is a number. If so, isolates the ID and adds "where" clause
$id      =   (!empty($_GET['ID']) && is_numeric($_GET['ID']))? " where ID = '".$_GET['ID']."'" : "";
// Add the $id to the end of the string
// A single call would be SELECT * FROM guestquestionnaire where ID = '1'
$query   =   $handler->query("SELECT * FROM guestquestionnaire{$id}");
$query->setFetchMode(PDO::FETCH_CLASS, 'guestquestionnaireEntry');

while($r = $query->fetch()) {
    echo $r->entry, '<br>';
}

?>

单击“查看此处”后我想显示的其他代码（因此当显示单个条目时）：

class guestquestionnaireEntry {
    public $id, $date_submitted, $choice, $expectations, $res, $res_information, $res_staff, $further_comments1,
        $entry;

public function __construct()
    {

$this->entry = "
         <tr style='font-size: 8pt;'><td width='60%'><a href=\"?ID={$this->ID}\">ID</a> </td><td width='40%' colspan='2'>{$this->date_submitted}</td></tr>

        <tr style='text-align: left; font:arial;'><td><h3>Date Submitted: {$this->date_submitted}</h3></td></tr>


        <table border='1' align='center'>

        <tr style='background: #566890; font-size: 8pt; font-weight: bold; color: #fff;'><td colspan='3'>Prior to Arrival</td></tr>


            <tr style='font-size: 8pt;'><td width='60%'>What made you choose us for your recent trip? </td><td width='40%' colspan='2'>{$this->choice}</td></tr>

            <tr style='font-size: 8pt;'><td>Did we meet your expectations as advertised? If no, please state why: </td><td width='40%' colspan='2'>{$this->expectations}</td></tr>


        <tr style='background: #566890; font-size: 8pt; font-weight: bold; color: #fff;'><td colspan='3'>Making your Reservation</td></tr><BR>


        <tr style='font-size: 8pt;'><td>Ease of making your reservation: </td><td width='40%'>$img</td><td width='5%'>{$this->res}</td></tr><BR>

        <tr style='font-size: 8pt;'><td>Hotel information offered: </td><td width='40%'>$img2</td><td width='5%'>{$this->res_information}</td></tr><BR>

        <tr style='font-size: 8pt;'><td>Warmth and friendliness of staff: </td><td width='40%'>$img3</td><td width='5%'>{$this->res_staff}</td></tr><BR>

        <tr style='font-size: 8pt;'><td colspan='3'>Further Comments: </BR></BR>{$this->further_comments1}</td></tr>

        <BR>

        </table>

        <BR>
        <p>Back to List</p>

看看这是否有效。我还没有测试过，所以请确保你保存了你目前所拥有的任何东西的副本。它需要填写数据库凭据：

类：

<?php
    interface   Database
        {   
            public  static  function SetConnection($host,$username,$password,$database);
        }

    interface   Questionnaire
        {
            public  function Display();
            public  function DisplaySingle();
        }

    class   MySQLConn implements Database
        {           
            protected   static  $host;
            protected   static  $username;
            protected   static  $password;
            protected   static  $database;

            public      static $connect;

            private function __construct()
                {
                }

            public  static  function SetConnection($host = "***",$username = "***",$password = "***",$database = "***")
                {
                    self::$host     =   $host;
                    self::$username =   $username;
