Question

我在需要显示数据库内容的网页上工作，让您点击它们以显示与该ID相关的数据库中的更多信息，甚至将内容旁边的复选框链接到相同的数据库ID我可以删除帖子，如果需要，我的代码显示到目前为止完美的内容，

但我不知道如何将与id相关的id / info链接到复选框或onclick命令

到目前为止我的代码：

<?php 
error_reporting(E_ALL); 
ini_set('display_errors', 1);

// Get our database connector
require("includes/conn.php");
?>

</head>

<body>
    <div id="featured">
    <h2></h2>

    <div>

   <?php 
   error_reporting(E_ALL); 
   ini_set('display_errors', 1); 

    // Grab the data from our people table

    $sql = "SELECT * FROM people ORDER BY ID";
    $result = mysql_query($sql) or die ("Could not access DB: " . mysql_error());

    while ($row = mysql_fetch_assoc($result))
    {
        echo "<div class=\"picture\">";
        echo "<p>";

        // Note that we are building our src string using the filename from the database
        echo "<img src=\"content/uploads/" . $row['filename'] . "\" alt=\"\" height=\"219\" width=\"350\" /><br />" . "<br />";
        echo $row['fname'] . " " . "<br />" . "<br />";
        echo "</p>";
        echo "</div>";
    }

    ?>

    </div>

</div>

</body>
</html>

无需复选框，您只需使用锚点

包装图像即可

然后，在其中放入一个包含查询字符串中id的URL：

echo "
<a href='moreinfo.php?id=".$row['id']."'>
    <img src=\"content/uploads/" . $row['filename'] . "\" alt=\"\" height=\"219\" width=\"350\" />
</a>
 <br />" . "<br />";
echo $row['fname'] . " " . "<br />" . "<br />";

强制性说明：

Please, don't use mysql_* functions in new code。它们不再被维护and are officially deprecated。请参阅red box？转而了解prepared statements，并使用PDO或MySQLi - this article将帮助您确定哪个。如果您选择PDO here is a good tutorial。

现在，在使用PDO的moreinfo.php内：

<?php
$results = array();
if(isset($_GET['id'])) {
    $id = $_GET['id'];
    $db = new PDO('mysql:host=localhost;dbname=DATABASE_NAME', 'username', 'password');

    $sql = 'SELECT * FROM people WHERE `id` = :id';
    $select = $db->prepare($sql);
    $select->bindParam(':id', $id, PDO::PARAM_INT);
    $select->execute();

    $results = $select->fetch(PDO::FETCH_ASSOC);
} else {
    header('Location: go_back_to_index.php');
}

?>

<?php if(!empty($results)): ?>
<h1>Results</h1>
<table cellpadding="10">
    <tr>
        <td>First Name:</td><td><?php echo $results['fname']; ?></td>
    </tr>
    <tr>
        <td>Last Name:</td><td><?php echo $results['lname']; ?></td>
    </tr>
    <tr>
        <td>Photo: </td><td><img src="content/uploads/<?php echo $results['filename']; ?>" alt="profile pricture" /></td>
    </tr>
    <!-- and so on -->
</table>
<?php endif; ?>

使用显示为onclick / checkbox id的MySQL id
