无法在HTML文件中调用PHP函数，尝试在不同的代码中使用相同的代码，但工作正常，但此处不行

Question

When I press the Login button it refreshes the page and doesn't do anything. 当我按“登录”按钮时，它将刷新页面，并且不执行任何操作。 I tried entering wrong Server IP just to check the error, but I guess it's not responding to the login button and directly refreshing the page. 我尝试输入错误的服务器IP只是为了检查错误，但我猜它没有响应登录按钮并直接刷新页面。

Unable to call a PHP function in the HTML file, tried using the same code in a different code and it's working fine there but not here: 无法在HTML文件中调用PHP函数，尝试在不同的代码中使用相同的代码，但在这里工作正常，但此处不行：

I just tidied up the HTML tags a little and used a better method of checking for POST data - but I think the issue was the badly formed HTML was confusing the form 我只是整理了一下HTML标记，并使用了一种更好的方法来检查POST数据-但我认为问题在于格式不正确的HTML会使表单混乱

Answer 2

if（$ _SERVER ['REQUEST_METHOD'] ==='POST'）请使用它代替if（$ _ POST）或使用if（isset（$ _ POST））
