我做了一个登录/注册页面。它在 chrome 和 firefox 上运行良好，但在 Internet Explorer (8、9) 上不起作用。单击任何提交按钮后，即重定向到索引页面。基于此代码，我在另一个页面上遇到了同样的问题。

这是html代码：

<?php

$log_in=false;
$token_sent=0;
$errors1 = array();
$missing1 = array();
$errors = array();
$missing = array();

if(isset($_POST['submit'])){
     $expected = array('login', 'email', 'pwd');
     $required = array('login', 'email', 'pwd');
     require('./rejestracja.inc.php');
}

if ($token_sent) {
    header('Location: (..) '); 
    exit;
}

if(isset($_POST['submit1'])) {
    $expected=array('login1','pwd1');
    $required=array('login1','pwd1');
    require('./login.inc.php');

    if($log_in) {
        if (isset($_SESSION['name']) && !empty($_SESSION['name'])) {
            unset($_SESSION['login1']);
            if (isset($_COOKIE[session_name()])) {
                setcookie(session_name(), '', time()-86400, '/');
            }
            session_destroy();
        }

        if (isset($_POST['login1'])) {
            session_start();
            $_SESSION['name'] = $login1 ;
        }
        header('Location: http:// (...) ');  
        exit;
    }
}

?>

这是'login.inc.php'代码：

<?php

$login1 = "";
$pwd1 = "";
$salt = "(...)";


/*---------------con------------------------*/
include('./sql_connect.inc.php');

/*---------------------------------------------*/
foreach ($_POST as $key => $value) {
     $temp = is_array($value) ? $value : trim($value);
     if (empty($temp) && in_array($key, $required)) {
          $missing1[] = $key;
     } elseif (in_array($key, $expected)) {
          ${$key} = $temp;
     }
}


if(!$missing1){
     $login1 = mysql_real_escape_string($login1); 
     $hash = $salt . $pwd1;
     for ( $i = 0; $i < 100; $i ++ ){
         $hash = hash('sha256', $hash);
     }

/*---------------COMPARE-----------------*/
      $result = mysql_query("SELECT user_nick='$login1' FROM users WHERE user_password='$hash'") or die('Sorry, we could not count the number of results: ' . mysql_error());
     if($result){
          if(mysql_result($result, 0)){

/*-------IS ACTIVATED?------------------------------*/
              $verified =  mysql_query("SELECT user_verified='yes' FROM users WHERE user_nick='$login1'");
              if($verified){
                  if(mysql_result($verified, 0)){
                      $log_in=true;          
                  }else{
                       $errors1['not_verified'] = true; 
                  }
               }
          }else{
               $errors1['wrong'] = true;    
          }
     }
}
mysql_close($con);

?>

你真的在用<form class='form' name="register" action=" " method="post">吗？它可以来自这里，试试action="#"

PHP不会有任何跨浏览器问题，它来自HTML（生成与否）
