Question

我是一个完全的初学者，我正在尝试为大学的项目制作表格。我只是在学习php而且我正在尝试测试我是否可以从我的php表单中获取值并在我继续将其链接到我的数据库之前将其输出。这是我的登录页面的完整代码，我使用bootstrap进行一些框架工作。所以我尝试使用POST方法并回显出名字和姓氏以查看它是否有效，当我按下提交按钮时它就不会回响。这真让我很沮丧。不要担心样式，我只想先将功能放在首位，是的，页面名为index.php。

<!doctype html>

Answer 1

你的错误就在这条线上

if(isset($POST['submit']))

使用它

if(isset($ـPOST['submit']))

PHP POST方法不起作用？
