标头不会重定向到另一个页面ajax php
[英]header doesn't redirect to another page ajax php
问题描述
我正在使用ajax概念处理登录表单请求。 在下面，我发布了与登录相关的代码。 它不会重定向到myaccount.php页面。 如果我使用此echo'<script>window.location="myaccount.php";</script>'; javascript函数，它将正常工作。 但是，在这里我想用PHP。 它将ajax消息返回myaccount.php结果。
我使用此<div id="loginreturn"></div>收到错误消息。 上面，我发布了错误图片。 myaccount.php页面结果还显示在<div id="loginreturn"></div> 。 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？
login.php
<?php
ob_start();
include('config.php');

{
$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();

'login.php'中的更改
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'中的更改
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
}
},
也许可以帮助您...
谢谢

尝试这个，
login.php
<?php
ob_start();
include('config.php');
error_reporting(E_ALL | E_WARNING | E_NOTICE);
ini_set('display_errors', TRUE);
$msg = array();
if($_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 = $row['Password'];
}
if($reemail == $_SESSION['ses_uemail'] && $repassword == $user_password)
{
$_SESSION['ses_name'] = $rename;
$_SESSION['ses_email'] = $reemail;
$_SESSION['ses_password'] = $repassword;
//header('Location:myaccount.php'); //no need
return json_encode(array('error'=> false));
}
else
{
//echo "Incorrect email id and password";
return json_encode(array('error'=> true, 'msg'=> "Incorrect email id and password"));
}
}
catch(PDOException $e)
{
//'Error : ' .$e->getMessage();
return json_encode(array('error'=> true, 'msg'=> $e->getMessage()));
}
}
ob_flush();
?>
ajax.js
// ajax signin
jQuery(document).ready(function() {
jQuery("#registertologin").click(function() {
jQuery("#loginreturn").html("<img src='img/loading.gif'/>");
var postData = $(this).serializeArray();

$.ajax( {
url : 'login.php',
type: "POST",
data : $('#loginform').serialize(),
dataType:"json",
success:function(data, textStatus, jqXHR) {
jQuery("#loginreturn").html('<pre><code class="returndata">'+data+'</code></pre>');
$("#loginform").submit_login(); //SUBMIT FORM
if(data.error)
{
console.log('data.msg');
}
else
{
window.location.href = 'myaccount.php';
}
},
error: function(jqXHR, textStatus, errorThrown)
{
