错误:SQLSTATE[42S22]:未找到列:“where子句”中的1054未知列“rowid”

我正在尝试通过ID传递a href。它一直给我这个奇怪的错误,尽管我以前做过很多次。错误是:

错误:SQLSTATE[42S22]:找不到列:1054未知列“rowid” 在“where子句”中

这是我在href中用于id的行:

<?php
    $link = mysql_connect("localhost", "root", "");
    mysql_select_db("meubelfabriek");
    $result = mysql_query("SELECT * FROM inbox") or 
    die(mysql_error());

    while($rowz = mysql_fetch_array($result)) {
        $id = $rowz['id'];

?>
<td>
<li class="list-group-item text-right"><a class="pull-left" href="login/email.php?id=rowid=<?= $rowz['id'] ?>">  <?php echo '<h7>' . $rowz['email'] . '</a> 2.13.2014</li>
</td>

电子邮件php

<?php
echo "<table style='border: solid 1px black;'>";
echo "<tr><th>Id</th><th>Firstname</th><th>Lastname</th></tr>";

class TableRows extends RecursiveIteratorIterator {
    function __construct($it) {
        parent::__construct($it, self::LEAVES_ONLY);
    }

    function current() {
        return "<td style='width:150px;border:1px solid black;'>" . parent::current(). "</td>";
    }

    function beginChildren() {
        echo "<tr>";
    }

    function endChildren() {
        echo "</tr>" . "\n";
    }
}


$servername = "localhost";
$username = "root";
$password = "";
$dbname = "meubelfabriek";

try {
    $conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    $id = $_GET['id'];

    $stmt = $conn->prepare("SELECT id, voornaam, achternaam, email, nummer, bericht FROM inbox WHERE id = $id");
    $stmt->execute();



    // set the resulting array to associative
    $result = $stmt->setFetchMode(PDO::FETCH_ASSOC);
    foreach(new TableRows(new RecursiveArrayIterator($stmt->fetchAll())) as $k=>$v) {
        echo $v;
    }
}
catch(PDOException $e) {
    echo "Error: " . $e->getMessage();
}
$conn = null;
echo "</table>";
?>

在我的数据库中,ID只是由ID定义的。所有prepare语句都写得很好。有人知道我为什么不能让它工作吗?在过去,它似乎工作得很好。无论如何,我希望任何人都能帮助我。
