Question

我有一个我正在执行的测试查询，它似乎运行正常，但是当使用varible传递或表的直接设置年份时，不会返回表行内的任何数据

    <?
$curyr = date("Y");
isset($_GET['year']) ? $year = $_GET['year'] : $year = "";
$server = $_SERVER['PHP_SELF'];

$dbhost = "localhost";
$dbuname = "";
$dbpass = "";
$dbname = "";
$conn = new mysqli($dbhost,$dbuname,$dbpass,$dbname);

if($conn->connect_errno):
    die("$conn->connect_error \n");
endif;

echo ("<title>$year</title>");

if (($year >= 2001) && ($year <=$curyr)) {
echo ("
<table border='0' align='center' width='100%'>
    <tr>
        <td>
            <table border='1' align='center' width='60%' style='border:1 solid #000000; border-collapse: collapse'>
                <tr>
                    <th align='center' colspan='5'>
                            DETAIL
                    </th>
                </tr>");
                $query = "SELECT c.* , p.* FROM $year c, dataset p WHERE c.id = p.id ORDER BY p.name ASC";
                $r = $conn->query($query);
                while ($row = $r->fetch_assoc()) {
                echo ("
                <tr>
                    <td>
                        &nbsp;$row[namepre]$row[name]
                    </td>
                    <td>
                    </td>
                    <td>
                        TEST
                    </td>
                    <td>
                    </td>
                </tr>");
                }
            echo ("
            </table>
        </td>
    </tr>
</table>");
} else {
    echo ("ERROR NO ROWS");
}
$conn->close();
?>

我正在回复＆＃34;详细信息＆＃34;样本表顶部的一部分，但没有别的。这只是基本的，但我想知道我可能遗漏的东西。

php / mysql基本搜索不返回结果
