Question

我有一个注册表单，它通过POST将输入变量移交给我的MySQLi脚本以插入数据库。问题是，每次运行脚本时，尽管E_ALL处于活动状态，我仍然遇到500错误并且没有任何错误详细信息。

我在上一个脚本中遇到了这个问题，最后通过替换所有

解决了这个问题

die("error_message");

目前的

echo ("error message);
exit;

但这次没有运气。如果我猜测，问题将在于将变量注入到SQL语句中，尽管Stackoverflow上的过去搜索向我展示了许多使用这种语法的示例。

有什么想法吗？感谢

编辑：由于有人标记这是重复的，让我解释为什么这些问题是不同的：

我的网站上的任何日志都没有错误日志。 E_ALL有效，但没有回报;
在网站上的另一个实例中使用了完全相同的MySQL脚本，但仅在此处我无法运行它。
我已经进行了大量的bug搜索，并运行了不同的脚本段来指出问题所在，但没有成功。

解：事实证明，根本没有收到任何错误消息的问题与if (isset($_SERVER['SERVER_REQUEST']))有关，我将其更改为if ($_SERVER["REQUEST_METHOD"] == "POST") {，然后最终出现错误。

Chrome似乎拒绝加载页面，以防万一遇到与$ _SERVER变量相关的任何错误，我不知道为什么我之前的语句提出了那个标志，但替代方案解决了问题并允许我运行其余的剧本。

MySQLi交互不起作用，没有返回错误，没有插入
