Question

我正在处理登录后的页面将转到仅限会员的页面。我昨晚有这个登录工作，然后我改变了一些东西，现在似乎会话没有保持设置。我今晚失去了理智。感谢。

登录表单

<div style="position: absolute; bottom: 175px">
  <button class="btn btn-default btn-xs" name="submit" role="button" data-toggle="modal" data-target="#myModal">Member Login</button>
</div>
  <!-- Modal -->
  <div id="myModal" class="modal fade" role="dialog">
    <div class="modal-dialog">

      <!-- Modal content-->
      <div class="modal-content">
        <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal">&times;</button>
          <h4 class="modal-title">Member Login</h4>
        </div>
        <div class="modal-body">
          <form method="post" action="" name="login_form">
          <p><input type="email" class="span3" name="email" placeholder="Email"></p>
          <p><input type="password" class="span3" name="password" placeholder="Password"></p>
          <p><button type="submit" id="submit" name="submit" value="Login" class="btn btn-primary">Sign in</button></p>
        </form>
        </div>
        <div class="modal-footer">
          <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        </div>
      </div>
    </div>
  </div>

的login.php

<?php
session_start();
include("connect.php"); //Establishing connection with our database

$error = ""; //Variable for storing our errors.
if(isset($_POST["submit"]))
{
if(empty($_POST["email"]) || empty($_POST["password"]))
{
$error = "Both fields are required.";
}else
{
// Define $email and $password
$email=$_POST['email'];
$password=$_POST['password'];

// To protect from MySQL injection
$email = stripslashes($email);
$password = stripslashes($password);
$email = mysqli_real_escape_string($db, $email);
$password = mysqli_real_escape_string($db, $password);
$password = sha1($password);

//Check email and password from database
$sql="SELECT id FROM Members WHERE email='$email' and password='$password'";
$result=mysqli_query($db,$sql);
$row=mysqli_fetch_array($result,MYSQLI_ASSOC);

//If email and password exist in our database then create a session.
//Otherwise echo error.

if(mysqli_num_rows($result) == 1)
{
$_SESSION['email'] = $email; // Initializing Session
$error = "Success!";
echo "<div class='alert alert-danger alert-dismissible' role='alert'>
        <button type='button' class='close' data-dismiss='alert' aria-label='Close'>
        <span aria-hidden='true'>&times;</span></button>".$error."</div>";
//header("location: members_only"); // Redirecting To Other Page
}else
{
$error = "Incorrect email or password.";
echo "<div class='alert alert-danger alert-dismissible' role='alert'>
        <button type='button' class='close' data-dismiss='alert' aria-label='Close'>
        <span aria-hidden='true'>&times;</span></button>".$error."</div>";
}

}
}

?>

仅限会员 这就是我在会员页面顶部的内容

<?php
session_start();
if (!isset($_SESSION['email']))
{
header('Location: index');
}
?>

当我填写登录表单并提交正确的用户名和密码时，我将被定向到索引，因为我的$ _SESSION [＆＃39;电子邮件＆＃39;]未设置。如果我删除测试，它将正确转到仅限成员页面。

Answer 1

我发现了我的问题。表单中的操作必须调出php文件。

php session（）似乎没有设置
