值肯定是POSTED但isset（）表示NO

See the code give given below. I was fighting with this code since last 5 hours to know why isset() is evaluating the condition as false if value is posted exactly what it shall POST. If I uncomment the line no. - 4,5,6,7,8 and put rest of the code from line no. 10 to 28 I can see the POSTED value . Can Anyone help in this by any guidance or suggestion. I will be thankful.

请参阅下面给出的代码。自从过去5个小时以来我一直在与这段代码作斗争，以了解为什么isset（）正在将条件评估为false，如果值的确是张贴它的POST。如果我取消注释行号。 - 4,5,6,7,8并将其余代码放在第5行。 10到28我可以看到POSTED值。任何人都可以通过任何指导或建议为此提供帮助。我会感恩的。

<?php
include 'dbconnection.php';
include 'functions.php';

// var_dump($_POST); what happens when you uncomment this line?

//sec_session_start();
 //  $email = $_POST['logemail'];
 //  $password = $_POST['p'];
//  echo $password;
//  echo $email;
 // Our custom secure way of starting a php session. 

if(isset($_POST['logemail'], $_POST['p'])) { 
   $email = $_POST['logemail'];
   $password = $_POST['p']; // The hashed password.
   if(login($email, $password, $mysqli) === true) {
      // Login success
      //$url = 'mwq';
    //echo '<META HTTP-EQUIV=Refresh CONTENT="0; URL='.$url.'">';  
    echo $password;
    echo $email;

   } else {
      // Login failed
      header('Location: login.php?error=1');
   }
} else { 
   // The correct POST variables were not sent to this page.
   echo 'Invalid Request Data Not POSTED';
}
?>

Without seeing the form I can only theorize what happens:

没有看到形式，我只能理解发生的事情：

You started with a clean slate, the form shows, you enter the username and password and submit it
您从一个干净的平板开始，表单显示，您输入用户名和密码并提交
The code passes the condition and then performs the login
代码传递条件然后执行登录
The result of login(...) !== true for whatever reason (wrong password or bug in the code)
登录（...）的结果！==无论出于何种原因都是真的（密码错误或代码中的错误）
The page redirects to login.php?error=1.
该页面重定向到login.php？error = 1。

Now, the $_POST is empty and $_REQUEST contains array('error' => 1). Perhaps the login.php shouldn't redirect to itself but rather redirect back to the page where you show the form.

现在，$ _POST为空，$ _REQUEST包含数组（'error'=> 1）。也许login.php不应该重定向到自己，而是重定向回到您显示表单的页面。
