无法登录（MySQL，PHP）

Question

So I need to make a whole login system for my graduation project. I already made a database on mysql which works perfectly. The register part of the login works but if I try to login with the account I just made, it doesnt work. Most of the time I'm getting the error 'Password/e-mail is wrong' while its correct?

Thanks in advance!

   <?php
    include("config.php");
    session_start();

    $email =$_POST['email'];
   $password =$_POST['password'];
   if(empty($email))
    {

        exit();

    }else {
      $stmt =mysqli_stmt_init($db);
      $sql = "SELECT * FROM users WHERE email=?;";

      if(!mysqli_stmt_prepare($stmt, $sql))
      {

        echo"No data";
      }else
      {
        mysqli_stmt_bind_param($stmt, "s", $email);
        mysqli_stmt_execute($stmt);
        $result = mysqli_stmt_get_result($stmt);
        if($row = mysqli_fetch_assoc($result))
        {
             $combicheck = password_verify($password,$row['password']);
            if($combicheck == false)
            {

                echo"Password / email is wrong";
                  exit();
            }else if($combicheck == true){
            session_start();
            $_SESSION['password'] = $row['password'];
            header('Location: index.html');
            echo"Logged in";
            }

        }else
        {
          echo"Failed";
        }
      }
    }

<form action="login.php" method="POST">
  <input type="text" name="" /> <br />
  <input type="password" name="" /> <br />
  <input type="submit" name="submit" value="login" />
</form>

Change display_errors=Off to display_errors=On in your php.ini file

if method="POST" then $_POST in php

if method="GET" then $_GET in php

If you are not sure is GET or POST method

debug using

In your login.php

echo "This is Post method";
var_dump($_POST);
echo "This is Get method";
var_dump($_GET);

</div>
