please help friends..
ANSWER ANSWER ANSWER
all the questions i asked i made silly mistakes...
here in this question i had not started session wile storing session variables....
add the below code in first line of login script
session_start();
//try this code
<?php
session_start();
if (!isset($_SESSION["att"]))
{
header("location: index.php");
}
?>
I think your asking to redirect if a session doesn't exist, since a session requires an ID you should be able to check against that:
if(!(session_id()) header("Location: /mypage.php");
Try this:
if(empty($_SESSION))
{
header("Location: /mypage.php");
}
else
{
// do something ....
}

i'm implementing session, cookie simple from with a remember me check box . i want to use the cookie so the user could see index.php(protected content) i closed the browser to end the session to check if the cookie working and i got the famous error ..redirected you too many . i searched a bit but still stuck so what should i do? and Is what is the best practice to for doing it?
authentication.php
if(mysqli_num_rows($rows) > 0){
$chck_pass = password_verify($clean_password,$user_arr["password"]);
if($chck_pass){
//log in the user
$_SESSION["id"] =$user_arr["id"];
$_SESSION["fristname"] = $user_arr["fristname"];
$_SESSION["email"] = $user_arr["email"];
$_SESSION["verified"]=$user_arr["verified"];
$_SESSION["message"]="Please verify Your Email to Complete Registration";
//make login-id cookie
if(isset($_POST["remmberme"])){
$user=$user_arr['id'];
setcookie("I_user",$user, time() + 1800);
}
header("location:index.php");
exit();
}else{
$errors["login_error"]="Wrong Password";}
}else{
$errors["login_error"]="Wrong Email";
index.php
<?php
include("Authentication.php");
if(!isset($_SESSION["id"]) || !isset($_COOKIE['I_user']) ){
header("location:login.php");
}
?>
login.php
<?php
require_once("config/db_connect.php");
require("Authentication.php");
if(isset($_COOKIE['I_user'])|| isset( $_SESSION['id'])){
header("location:index.php");}
So you login, close your browser. Then open it up again.
You go to index.php and the following line runs
if(!isset($_SESSION["id"]) || !isset($_COOKIE['I_user']) ){
$_SESSION["id"] isn't set, so you redirect to login.php.
On login.php
if(isset($_COOKIE['I_user'])|| isset( $_SESSION['id'])){
$_COOKIE['I_user'] is set, so you redirect to index.php
Repeat forever.
My logout.php file is like this. Is there any mistake in my code
logout.php
<?php
session_start();
session_destroy();
header('Location:index.php');
exit;
?>
Here is my index.php file. If I am set $_SESSION['s_activId'] then it is working properly but when I am trying to put condition if $_SESSION['s_activId'] is not set at that time I want to pass header on index page sometimes it works sometimes it does not work.
<?php
include('include/config.inc.php');
if(!isset($_SESSION['s_activId']))
{
$_SESSION['s_urlRedirectDir'] = $_SERVER['REQUEST_URI'];
header("Location:index.php");
}
else
{
$wrong = '';
if(isset($_POST['submit']))
{
$checkLogin = "SELECT userName,password,userType
FROM user
WHERE BINARY userName = '".$_POST['userName']."'
AND BINARY password = '".$_REQUEST['password']."'";
$checkLoginresult = mysql_query($checkLogin);
if($userLoginRow = mysql_fetch_array($checkLoginresult))
{
$_SESSION['s_activId'] = $userLoginRow['userName'];
$_SESSION['s_password'] = $userLoginRow['password'];
$_SESSION['hg_userType'] = $userLoginRow['userType'];
if(!$_SESSION['s_urlRedirectDir'])
{
header("Location:index.php");
}
else
{
header("Location:reminder.php");
}
}
else
{
$wrong = "UserId And Password Is Not Valid";
}
}
}
include("bottom.php");
$smarty->assign('wrong',$wrong);
$smarty->display("index.tpl");
?>
The problem arise in the condition below in index.php:
if(!isset($_SESSION['s_activId']))
{
$_SESSION['s_urlRedirectDir'] = $_SERVER['REQUEST_URI'];
header("Location:index.php");
}
When you logout, you are calling session_destroy() on logout.php and redirecting on index.php and the condition above gets true as s_activId is not set in session and again you are redirecting on index.php (without setting s_activId in session). The above condition will be true until the variable s_activId set in session and because of this you are getting ERR_TOO_MANY_REDIRECTS error.
The solution is, on index.php set the variable s_activId in session before calling the header method. Refer the code below:
if(!isset($_SESSION['s_activId']))
{
$_SESSION['s_urlRedirectDir'] = $_SERVER['REQUEST_URI'];
$_SESSION['s_activId'] = true;
header("Location:index.php");
}
Dont redirect index.php to index.php. you having redirects loop. Also
if you have code below that also can fire add die in if because after
redirect code below still executes. I didnt read your code, maybe
there isnt problems with this but after
header("Location: lalala"); always add die(); or exit();
I need a little help here. I have a page profile.php and a option to delete the accound :
// DELETE THE ACCOUNT !!
$_SESSION["delacc"] = FALSE;
if (isset ($_POST ['deleteaccount'])) {
$deleteaccount = $_POST['deleteaccount'];
$delacc="DELETE FROM users WHERE username='$username'";
$resdelacc = mysqli_query($con,$delacc);
if ($resdelacc) {
header('Location: index.php');
$_SESSION["delacc"] = TRUE;
unset($_SESSION['username']);
} else {
echo "ERROR !!! Something were wrong !!";
}
}
the problem is in if ($resdelacc). If this is true, result that the account was deleted, unset session username (logout) and after this I want to redirect the page to index.php where I have the code :
if(isset($_SESSION["delacc"])) {
if($_SESSION["delacc"] == TRUE) {
echo "<b><font color='red'>YOUR ACCOUNT WAS SUCCESFULLY DELETED !!</font></b>";
$_SESSION['delacc'] = FALSE;
}
}
My only problem is that this line " header('Location: index.php');" (from profile.php) don't run in any case. When the user click the button "DELETE ACCOUNT", the page remain profil.php, then, if do refresh or access another page, is redirected and appear as guest.
Very easy .. The reason is after in the resulted output page you can't redirect. so you've prepare it to be redirected after some seconds enough for user to read the result message.
Like this:
if($_SESSION["delacc"] == TRUE) {
$_SESSION['delacc'] = FALSE;
echo '<!DOCTYPE html><html><head><meta http-equiv="refresh" content="7;url=http://'.$_SERVER['HTTP_HOST'].'/index.html"/>';
echo "</head><body>";
echo "<b><font color='red'>YOUR ACCOUNT WAS SUCCESFULLY DELETED !!</font></b>";
}
that change will redirect to the index.html after 7 seconds.
PS. The Generated HTML result page make it starts by this code after the POST handling direct. (before any echo) because echo will start generating the results page and the only logical place to redirect is inside the HEADER before any BODY elements
<meta http-equiv="refresh" content="0";url="/index.php"/>
The redirect (url) don't run for index.php because I have another redirect before :
if(isset($_SESSION['username'])==FALSE) {
header('Location: login.php');
}
but is ok, I put the message "DELETED SUCCESFULLY" in login.php and deleted from index.php . I set content=0, because after deleted, the user will be restricted for page profile.php and need to change immediatelly to another. Due of the verification of SESSION['username'] which can return profile.php, I can not redirect to another page ... is a conflict. I need a little to think better this code with redirects, I know can solve it better :D thanks for explanations and help
Hi i'm developing a multi steps form with php using session and i've been wondering if there is a way for the user to alter session variables for example on the first page i have something like this :
<?php
session_start();
if(isset($_POST['submit'])){
$_SESSION['name'] = $_POST['name'];//and so on
}
?>
and the other page has something like :
<?php
session_start();
$name = $_SESSION['name'];
?>
my question is can the user modify the value of the session variable on the second page
Since you're populating the session variable with the value of a POST variable, they can continue to resubmit the first form as much as they want with arbitrary values.
You can use application logic to defeat this:
<?php // form1
session_start();
if (empty($_SESSION['step'])) {
$_SESSION['step'] = 1;
}
if ($_SESSION['step'] > 1) {
header("Location: form2.php");
exit; // This exit is very important, don't neglect it
}
if (isset($_POST['submit'])){
$_SESSION['name'] = $_POST['name'];//and so on
$_SESSION['step'] = 2;
}
And then
<?php // form2
session_start();
if (empty($_SESSION['step'])) {
header("Location: form1.php");
exit;
}
if ($_SESSION['step'] > 2) {
header("Location: form3.php");
exit;
}
if ($_SESSION['step'] < 2) {
header("Location: form1.php");
exit;
}
$name = $_POST['name'];
By using application logic, you can control the flow of your visitors within your application.
If you're asking if users can change $_SESSION variables outside of any code you've written, the answer is usually no. See also: this answer.
How it should work:
Index.php is the secured page. It includes check.php, which checks if you have a session = good. If it hasn't, you're not logged in -> log off, remove session. But it doesn't work, it always logs off, like I didn't log in...
index.php
include ‘check.php’;
echo "logged in";
check.php
session_start();
if($_SESSION[‘login’] != ‘good’) {
unset($_SESSION[‘login’]);
unset($_SESSION[‘name’]);
header(‘Location: login.php?logoff’);
exit();
}
Login.php
if(isset($_POST[‘login’])) {
$gb = array();
$gb[‘user1’] = ‘pass1’;
$gb[‘user2’] = ‘pass2’;
if(isset($gb[$_POST[‘username’]]) && $gb[$_POST[‘username’]] == $_POST[‘password’])
{
$_SESSION[‘login’] = ‘good’;
$_SESSION[‘name’] = $_POST[‘name’];
header("Location: index.php");
} else {
header("Location: login.php?wrongpass");
}
} else { ?>
Login Form
<?php } ?>
I hope someone can help me!
You should verify you started the session in login.php.
Put session_start(); in all the pages
You need to have session_start() at the top of all the pages, you havent shown the session start for your login page.
(Thanks to Danny for proving I cant type)
Check that you have register_globals is On in your php.ini
First check on the pages you want to use session variables session is start or not and if session is not stat then start it.
and this is the very first line in the php file.
Code for the session checking is :
if(!session_id())
{
session_start();
}
if($count==1){
session_start();
$_SESSION['Username'] = $UserName;
$_SESSION['Password'] = $password;
UpdateOnlineChecker($Session);
header( "Location: http://". strip_tags( $_SERVER ['HTTP_HOST'] ) ."/newHolo/" );
exit;
}
else {
echo "Wrong Username or Password";
}
Look at my code. It checks if the statement is true (for me, if there is one row with a query statement i execute). Then i start a session and basically Ill define global session variables, sned out a query to my database to update the session and then refer through.
you are missing a session_start(); in your if true block.
Use one for action document such as index.php there is code:
session_start();
if(isset($_POST['login']) && isset($_POST['password'])){
// login
header('Location: (here is some page)');
}
if(!isset($_SESSION['user']){
// #todo some action
} else {
require_once('login.php');
}
if(isset($_GET['logout'])){
unset($_SESSION['user']);
header('Location: (here is some page)');
}
I think problem is header:
('location:------.php);
Your hosting server doesn't run this.
You can use this:
echo "<script>window.location.href='-----.php'</script>";
