这在我的本地主机上运行得非常好,但是当我在线托管时,它不会登录并且它回显成功且没有错误。请问这可能是什么原因?
<?php
session_start();
$_SESSION['user_logged']=$user;
$_SESSION['user_password']=$password;
$user = $_POST["username"];
$password = $_POST["password"];
include("include/connect.php");
$msg = array();
if(isset($_POST['submit'])){
foreach($_REQUEST as $key=>$val){
$$key=$val;
}
if(count($msg)==0){
$sql="SELECT username, password FROM admin WHERE username='$username' && password='$password'";
$res=mysql_query($sql) OR die(mysql_error());
if(mysql_fetch_array($res)>0){
$_SESSION['user_logged']= $user;
$_SESSION['user_password']=$password;
header("location:dashboard.php");
echo "You looged in Successfully";
} else{
$msg[]='Incorrect username/password';
}
}
}
?>
以下是它想要重定向到的dashboard.php。
<?php
include('include/connect.php');
include('include/function.php');
if(isset($_REQUEST['mode']) )
{
$mode=$_REQUEST['mode'];
if($mode == 1)
{
$id=$_REQUEST['id'];
$sql="DELETE FROM enquiry WHERE id='$id'";
$result=mysql_query($sql);
}
}
$msg=array();
if(isset($_POST['submit'])){
$title=$_POST['news'];
$news_item=$_POST['news'];
if(empty($news_item)){
$msg[]='You must enter news in the column!';
}
if(empty($title)){
$msg[]='News Title must not be empty!';
}
else {
$sql = "SELECT * FROM news_file WHERE title='$title' ";
$res = mysql_query($sql) or die(mysql_error());
$result = mysql_fetch_array($res);
if($result > 0){
$msg[] = 'News with the same title has been added already';
} else {
$sql = "INSERT INTO news_file (title,news,date) VALUES ('$title','$news_item',Now())";
$result = mysql_query($sql);
$msg[]='News was successfully added';
}
}
}
?>
答案 0 :(得分:0)
试试这个。
<?php
session_start();
/*
These should be the other way round, as you are setting
the session variables with variables which have not been
initialised yet
*/
$user = $_POST["username"];
$password = $_POST["password"];
$_SESSION['user_logged']=$user;
$_SESSION['user_password']=$password;
include("include/connect.php");
$msg = array();
if(isset($_POST['submit'])){
foreach($_REQUEST as $key=>$val){
$key=$val; // Removed Erroneous double $
}
if(count($msg)==0){
$sql="SELECT
username,
password
FROM
admin
WHERE
username='$username'
AND
password='$password'";
// MySql does not accept && as a comparison operator.
$res=mysql_query($sql);
if(!$res)
{
var_dump(mysql_error());
exit;
}
else
{
if(mysql_fetch_array($res)>0)
{
$_SESSION['post'] = $_POST;
while(mysql_fetch_array($res)>0)
{
$_SESSION['user_logged']= $user;
$_SESSION['user_password']=$password;
header("location:dashboard.php");
echo "You logged in Successfully";
}
}
else
{
msg[]='Incorrect username/password';
}
}
?>
查看您为dashboard.php
提供的代码,您希望有一个$_POST
数据,用于您重定向到的页面。在您重定向到页面的位置,您将无法从服务器检索$_POST
数据。
我已经修改了上面的脚本,将$_POST
数据存储在会话中,所以使用它,你应该可以通过调用$_SESSION['post']['news']
来调用你的新闻,或者如果这个太长了winded,只需在dashboard.php
脚本中重新分配一次POST数据,就像这样。
$post = $_SESSION['post'];
然后您可以使用$post['news']
来调用它。
