Question

大家好，请帮助我开发了我的第一个网站www.ncrwallpaper.com。我的问题是每当我从登录页面登录时。 1，它不会重定向到目标页面 2已登录，但在当前页面中没有显示..

这是我的代码

<?php
session_start();
include('dbfunctions.php');
include_once('top.php');

if(isset($_POST['login'])) {
    $a=$mysqli->real_escape_string($_POST['email']);
    $b=$mysqli->real_escape_string($_POST['pass']);
    $c=$mysqli->query("select * from users where email='$a' and pass='$b'");
    $count=$c->num_rows;

    if($count==1){
        $f=$c->fetch_object();

        //value assign in session_id
        $_SESSION["id"]=$f->id;
        $_SESSION["email"]=$f->email;
        $_SESSION["name"]=$f->name;
        $_SESSION["contact"]=$f->contact;

        if(isset($_SESSION['url'])) $url = $_SESSION['url']; // holds url for last page visited.
            else $url = "index.php";

        header("Location: $url"); 
    } else echo "Please enter valid email id and password";
}

?>

此代码已在localhost上运行

<form action="#" method="post" enctype="multipart/form-data">
    <input type="email" name="email" placeholder="E-Mail Address" id="input-email" class="form-control" required autofocus/>
    <input type="password" name="pass" placeholder="Password" id="input-password" class="form-control" required/>
    <input type="submit" value="Login" class="btn btn-primary" name="login" />
</form>

Answer 1

在header输出您使用的javascript ，output buffering或元刷新选项top.php中的css之后，您无法使用echo '<meta http-equiv="refresh" content="0; URL=' . $url . '">';

重定向

<?xml version="1.0" encoding="UTF-8"?> <doc> <ticker> CSGN.VX </ticker> <stockExchange> NYSE </stockExchange> <stockDatas> <stockData> <date>2015-08-06</date> <closingPrice>140</closingPrice> </stockData> <stockData> <date>2015-08-07</date> <closingPrice>140.25</closingPrice> </stockData> <stockData> <date>2015-08-10</date> <closingPrice>140.75</closingPrice> </stockData> </stockDatas> </doc>是网站在刷新前应显示的延迟时间

Answer 2

您可以使用ob_start()＆amp; ob_end_clean()

<?php
ob_start();
session_start();
include('dbfunctions.php');
include_once('top.php');

if(isset($_POST['login'])) {
    $a=$mysqli->real_escape_string($_POST['email']);
    $b=$mysqli->real_escape_string($_POST['pass']);
    $c=$mysqli->query("select * from users where email='$a' and pass='$b'");
    $count=$c->num_rows;

    if($count==1){
        $f=$c->fetch_object();

        //value assign in session_id
        $_SESSION["id"]=$f->id;
        $_SESSION["email"]=$f->email;
        $_SESSION["name"]=$f->name;
        $_SESSION["contact"]=$f->contact;

        if(isset($_SESSION['url'])) $url = $_SESSION['url']; // holds url for last page visited.
            else $url = "index.php";

        $output = ob_get_contents();
        ob_end_clean();
        header("Location: $url"); 
    } else echo "Please enter valid email id and password";
}

?>

Answer 3

尝试使用此代替您的标题

<script type="text/javascript">
window.location.assign('your desired location');
</script>

注意：在脚本标记之前关闭php并在关闭脚本标记后打开php

Answer 4

<?php
session_start();
include('dbfunctions.php');
?>
<?php include_once('top.php'); ?>
<?php
if(isset($_POST['login']))
{
$a=$mysqli->real_escape_string($_POST['email']);
$b=$mysqli->real_escape_string($_POST['pass']);
$c=$mysqli->query("select * from users where email='$a' and pass='$b'");
$count=$c->num_rows;
if($count==1){
$f=$c->fetch_object();
//value assign in session_id
$_SESSION["id"]=$f->id;
$_SESSION["email"]=$f->email;
$_SESSION["name"]=$f->name;
$_SESSION["contact"]=$f->contact;
if(isset($_SESSION['url'])) 
$url = $_SESSION['url']; // holds url for last page visited.
else 
$url = "index.php";

echo " <script type=\"text/javascript\">
window.location.assign('blaahh.php');
</script> ";
}
else{
echo "Please enter valid email id and password";
}

}

?>

Answer 5

你需要一些JS。只需将此代码放在标题中：

 ?> // close php
<script type="text/javascript">
window.location.assign('location');
</script>
<?php // open php again

Answer 6

<强> PHP：

header("Location: yourpage.php");
exit;

您必须在标题后使用exit或die才能停止执行代码。此外，代码必须在任何输出之前执行。

登录页面没有重定向到PHP中的目标位置？
