我需要从我的表“报告”中获取“id”列以获取唯一值并使其可链接。

元素的链接格式如下：http://www.mysite.com/id， （包括逗号）

您能帮我如何从id列获取信息并使其在结果中可点击吗？

    $MySQLPassword = "*****";   
    $HostName = "***";  
    $UserName = "***";
    $Database = "****";

    mysql_connect($HostName,$UserName,$MySQLPassword)
    or die("ERROR: Could not connect to database!");
    mysql_select_db($Database) or die("cannot select db");


    $default_sort = 'ID';
    $allowed_order = array ('name','description');

    if (!isset ($_GET['order']) || 
        !in_array ($_GET['order'], $allowed_order)) {
        $order = $default_sort;
    } else {
        $order = $_GET['order'];
    }


    if (isset($_GET['keyword'])) {

            if(!$_GET['keyword']) {
              die('<p>Please enter a search term.</p>');
        }

我没有在您的代码中看到查询，但总体思路如下：

$result = mysql_query("SELECT id, name FROM reports WHERE field = value") or die(mysql_error());

while ($row = mysql_fetch_assoc($result)) {
    echo '<a href="mysite.com/' . $row['id'] . ',">' . $row['name'] . '</a>';
}

请记住，不推荐使用 mysql_* 函数。您应该使用 mysqli 或PDO。
