Question

我有一个页面，显示我的表单（在网页中）的回复。目前，所有的回复都在一页上，一个接着一个。我希望该页面显示提交的所有日期（date_submitted）和ID号码的列表，当点击它时，它会将我们带到具有该特定响应的页面（即完整响应）。如何创建将其带入此记录的链接？

这是该页面的代码：

<?php error_reporting(E_ALL); ?>

<head>
<link rel="stylesheet" type="text/css" href="surveystyle.css" media="all" />
</head>
<body>
<div id="container2">
    <div class="logo-header"><img src="images/logo.jpg" alt="" width="205" height="119" /></div>
    <h2> Guest Questionnaire Responses </h2>
<?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, $choice, $expectations, $res, $res_information, $res_staff, $further_comments1, 
        $entry;

        public function __construct()
            {
                $this->entry = "<a href=\"?ID={$this->id}\">ID</a>
    <tr style='text-align: left; font:arial;'><td><h3>Date Submitted: {$this->date_submitted}</h3></td></tr>

            <BR>
            <table border='1' align='center'>
                <tr style='background: #566890; font-size: 8pt; font-weight: bold; color: #fff;'>

                </tr>
                <tr style='font-size: 8pt;'>
                    <td width='60%'>What made you choose us for your recent stay? </td>
                    <td width='40%' colspan='2'>{$this->choice}</td>
                </tr>
                <tr style='font-size: 8pt;'>
                    <td>Did our hotel meet your expectations as advertised? If no, please state why: </td>
                    <td width='40%' colspan='2'>{$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>

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

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


// 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>';
    }
?>
    </div>
</body>

您需要在sql中执行 <a href="?ID=<?php echo $this->id; ?>">ID</a>：

HTML按钮：

// 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');

SQL查询：

// Should be something like this
public function __construct()
    {
        $this->entry = "
        <a href=\"?ID={$this->id}\">ID</a>...etc.
