我有 2 个 PHP 表单。一个显示事件列表,另一个显示每个特定事件的结果。在包含事件列表的页面上,我想要它,以便可以创建超链接来访问每个单独事件的结果。

例如,在“事件”页面上,我单击第 2 行的超链接,然后将我带到包含该特定事件结果的“结果”页面。

任何帮助将不胜感激,因为我对 PHP 非常非常陌生。如果需要任何额外的细节,请随时询问。

谢谢。

编辑:抱歉,我将向您展示到目前为止的事件表单:

<?php
mysql_connect('localhost','root','');
mysql_select_db('clubresults') or die( "Unable to select database");
$sql = "SELECT *, DATE_FORMAT(EventDate, '%d/%m/%y') as newdate FROM Events";
$result = mysql_query ($sql);
?>
<table border = 1>
<tr>
<th>Event ID</th>
th>Event Name</th>
<th>Event Date</th>
<th>Location</th>
</tr>
<?php
 while ($row = mysql_fetch_array($result))
{
echo "</td><td>" . $row['EventID'] . "</td><td>" . $row['EventName'] . "</td><td>" . $row['newdate'] . "</td><td>" . $row['Location'] . "</td><tr>";
}
echo "</table>";
mysql_close();
?>

您不需要两个脚本,而只需要一个:

events.php?list
events.php?event=1234

在那里你只需要检查一些东西:

$db = new Database(); # simplified


/* show event details if requested */

if (isset($_GET['event']) {
    if ($event = $db->getEventByID($_GET['event'])) {
        printf('<h2>Event: %s</h2>', htmlspecialchars($event->title));
        # ...
    }
}

/* show the list if requested (or show it always, whatever pleases you) */

if (isset($_GET['list']) {
    echo '<table>';
    foreach($db->getEventList() as $event) {
        printf('<tr><td><a href="?event=%d">%s</a></td></tr>'
               , $event->ID, htmlspecialchars($event->title));
    }
    echo '</table>';
}

编辑:正如我在您更新的问题中看到的那样,您应该从那些 oldskoolmysql_*函数切换到我在示例中概述的类样式,因为它使用起来更简单。这是一个接近您的代码示例:

<?php
/**
 * My First PDO Databaseclass
 */
class Database extends PDO
{
    public function __construct()
    {
        $host = 'localhost';
        $name = 'clubresults';
        $user = 'root';
        $pass = NULL;

        parent::__construct("mysql:host=$host;dbname=$name", $user, $pass);
        $this->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        // $this->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
    }

    public function getEvents()
    {
        $sql = "SELECT *, DATE_FORMAT(EventDate, '%d/%m/%y') as newdate FROM Events";
        return $this->query($sql, PDO::FETCH_OBJ );
    }

    public function getEventByID($id)
    {
        $sql = sprintf("SELECT * FROM Events WHERE EventID = %d;", $id);
        return $this->query($sql)->fetchObject();
    }
}

$db = new Database();

?>
<table border=1>
    <tr>
        <th>Event ID</th>
        th>Event Name</th>
        <th>Event Date</th>
        <th>Location</th>
    </tr>
<?php
foreach($db->getEvents() as $event)
{
     echo "</td><td>" . $event->EventID . "</td><td>" . $event->EventName . "</td><td>" . $event->newdate . "</td><td>" . $event->Location . "</td><tr>";
}
?>
</table>
