Question

我正在使用ajax概念处理登录表单请求。下面我发布了与登录相关的代码。它不会重定向到myaccount.php页面。如果我使用这个echo'<script>window.location="myaccount.php";</script>'; javascript函数，它将正常工作。但是，这里我想用PHP做。 它将myaccount.php结果作为ajax消息返回。

Error image

我正在使用此<div id="loginreturn"></div>收到错误消息。上面我发布了一个错误图片。 myaccount.php页面结果也显示在<div id="loginreturn"></div>内。那是我的问题。它不会重定向到另一个php页面。如何解决这个错误？

的login.php

<?php
    ob_start();
    include('config.php');
    error_reporting(E_ALL | E_WARNING | E_NOTICE);
    ini_set('display_errors', TRUE);
    if($_SERVER['REQUEST_METHOD'] == "POST")
    {
        $user_email = $_POST['email'];
        $user_password = $_POST['password'];    
        $_SESSION['ses_uemail'] = $user_email;
        if(empty($user_email) || empty($user_password) )
        {
            echo "You must provide your email id and password";
            die();
        }       
        try
        {
            $stmt = $conn->prepare("SELECT * FROM table_name WHERE EmailID = ? AND Password = ?");
            $conn->errorInfo();
            $stmt->bindParam('1', $user_email, PDO::PARAM_STR);
            $stmt->bindParam('2', $user_password, PDO::PARAM_STR);
            $stmt->execute();
            while($row = $stmt->fetch())
            {
                $rename = $row['Name'];
                $reemail = $row['EmailID'];
                $repassword = $row['Password'];
            }

            {
                $_SESSION['ses_name'] = $rename;

                header('Location:myaccount.php');

Answer 1

'login.php'的变化

while($row = $stmt->fetch())
 {
      $rename = $row['Name'];
      $reemail = $row['EmailID'];
      $repassword = $row['Password'];
 }       
 if($reemail == $_SESSION['ses_uemail'] && $repassword == $user_password)
 {
      $_SESSION['ses_name'] = $rename;
      $_SESSION['ses_email'] = $reemail;
      $_SESSION['ses_password'] = $repassword;
      return true;
 }else
 {
      return false;
 }

'ajax.js'的变化

success:function(data, textStatus, jqXHR) {
if(data == true)
{
     window.location.href="myaccount.php"
}else
{
     jQuery("#loginreturn").html('<pre><code class="returndata">'+data+'</code></pre>');
     $("#loginform").submit_login(); //SUBMIT FORM
}

},

也许它可以帮助你...
