我正在尝试使用下面的表单执行更新，但是，每次我尝试更新表单时，我都会收到“检测到空字段”错误但是，我似乎无法找到错误。我可以帮忙吗。

5 个答案:

答案 0 :(得分：2)

您检查空$firstname $middlename ...等，而不是$_POST['firstname']等。 如果你的php配置中的register_globals关闭（默认），那么你的方法将不起作用。

答案 1 :(得分：1)

写

 extract($_POST)

之前if(!empty($firstname)

这将有助于您将值$firstname用于代替$_POST['firstname']，$middlename而非撰写$_POST['middlename']等等

答案 2 :(得分：0)

你的第二个if中的变量（如$firstname）永远不会被设置，所以你为什么期望那里有一些价值？

你的if条件应该是

if(!$empty($_POST['firstname']) ... )

所以用$variable替换$_POST['variable']并自己检查脚本的其余部分，因为你的sql语句也不起作用。

答案 3 :(得分：0)

如果你不能打开“register_globals”（这是不安全的那么糟糕的主意）
您需要在脚本中更改所有变量，例如
$ firstname，$ middlename，$ address，$ email ....
成：
$ data ['firstname']等....

但如果你不关心安全问题，你也可以这样做：

foreach($_POST AS $k=>$v)
{
    $data[$k] = $v;
    $$k = $v;
}

答案 4 :(得分：-1)

请替换

foreach($_POST AS $k=>$v)
{
    $data[$k] = $v;
}

要

foreach($_POST AS $k=>$v)
{
    $k = $v;
}

希望它能为你效劳
