我的更新表单遇到问题。表单不会从数据库中检索任何数据。

谁能告诉我哪里出错了。

这是我的更新页面编码。

＆＃13;

Install-Package RestSharp

＆＃13;

这是更新表单编码

除了其他人提到的（这篇文章没有足够的信息，格式也不好）。我最好的猜测：你正在混合$ _GET和$ _POST。

你有一个块

if (isset($_GET['No_Siri_Komputer'])) {
    $colname_Recordset1 = $_GET['No_Siri_Komputer'];
}

应该是：

if (isset($_POST['No_Siri_Komputer'])) {
    $colname_Recordset1 = $_POST['No_Siri_Komputer'];
}

否则$ colname_Recordset1将始终为-1，我认为这不是你想要的。

更新数据表单不是从数据库中检索任何信息以在php中编辑
