我已经为管理面板建立了一个登录页面，成功登录后，页面将重定向到dashboard.php.当我在本地主机上运行时，它工作正常，会话也工作。但是当我在页面上传时，页面没有重定向，它只是重新加载登录页面。我的会话代码是
<?php
session_start();
if(isset($_SESSION['user']) && isset($_SESSION['pass']))
{
header('Location: dashboard.php');
}
?>
验证码和重定向码
<?php
//session_start();
function login($username, $password)
{
$query = "SELECT * FROM user WHERE username='$username' AND password='$password'";
$result = mysql_query($query)or die(mysql_error());
$num_row = mysql_num_rows($result);
if( $num_row == 1 )
{
while( $row=mysql_fetch_array($result) )
{
return true;//$_SESSION['userid'] = $row['userid'];
}
} else {
return false;
}
return true;
}
include("connect.php");
if (isset($_REQUEST['login'])){
$validLogin = login($_REQUEST['user'], $_REQUEST['pass']);
if ($validLogin)
{
$_SESSION['user'] =$_REQUEST['user'];
$_SESSION['pass'] = $_REQUEST['pass'];
header("Location: dashboard.php");
echo 'hi there';
} else
{
echo "<font color='white'><h1> Incorrect Details,Entry Prohibited :) </h1></font> ";
}
}
?>
<?php
ob_start();
?>
第一行
if ($validLogin)
{
$_SESSION['user'] =$_REQUEST['user'];
$_SESSION['pass'] = $_REQUEST['pass'];
header("Location: dashboard.php");
exit;
} else
{
echo "<font color='white'><h1> Incorrect Details,Entry Prohibited :) </h1></font> ";
}
你不能在header()之后再做echo。取消注释并添加一个出口，如下所示。
if ($validLogin)
{
$_SESSION['user'] =$_REQUEST['user'];
$_SESSION['pass'] = $_REQUEST['pass'];
header("Location: dashboard.php");
//echo 'hi there'; //<------ Commented this
exit;// <---- Added exit
} else
{
echo "<font color='white'><h1> Incorrect Details,Entry Prohibited :) </h1></font> ";
}
删除Location:后的空格，并尝试以下代码
头(地点:dashboard.php);
尝试使用ob_clean
if ($validLogin)
{
ob_clean();// <---- Added this
$_SESSION['user'] =$_REQUEST['user'];
$_SESSION['pass'] = $_REQUEST['pass'];
header("Location: dashboard.php");
//echo 'hi there'; //<------ Commented this
exit;// <---- Added exit
} else
{
echo "<font color='white'><h1> Incorrect Details,Entry Prohibited :) </h1></font> ";
}
