单击Submit按钮打开一个空白的action.php，既没有错误消息，也没有在表中插入数据。
询问是否有人可以共享action.php的简洁代码或指导我使用同一代码。我在connection.php中有数据库登录凭据
我的表单具有以下代码：
<form class="form-horizontal" action="action.php" method="Post">

$thiscat =mysql_fetch_array($res1);
?>
<select name="vlocation" class="form-control" value="<?php echo $thiscat['location']; ?>">

由于我对PHP的了解很少，因此寻求论坛支持。积极乐观
