您需要在sql中执行where
：
HTML按钮：
<!-- Use whatever here to click on that triggers the ID reload -->
<a href="?ID=<?php echo $this->id; ?>">ID</a>
// Checks if the submitted is a number. If so, isolates the ID and adds "where" clause
$id = (!empty($_GET['ID']) && is_numeric($_GET['ID']))? " where ID = '".$_GET['ID']."'" : "";
// Add the $id to the end of the string
// A single call would be SELECT * FROM guestquestionnaire where ID = '1'
$query = $handler->query("SELECT * FROM guestquestionnaire{$id}");
$query->setFetchMode(PDO::FETCH_CLASS, 'guestquestionnaireEntry');
// Should be something like this
public function __construct()
{
$this->entry = "
<a href=\"?ID={$this->id}\">ID</a>...etc.

谢谢。这与我上面列出的代码在同一页上吗？有点困惑该放在哪里。是的，sql查询会添加行并替换您的行。HTML按钮会放在构造（）中的某个地方不过你想把它摆出来。这可能更像是
思想谢谢，但我似乎无法让它工作。你更新的最后一行（也是你评论中提到的那一行）给我一个空白页，就好像有错误一样。很可能有错误。将
