PHP - Stuck On _session Issues
Hey Guys/Gals
Benn awhile - so I'm confused on what's happening here. session_start() being called on every page, index.php, registration.php and server.php aswell as login.php. Now when I go too login - if I edit the code to echo the $_SESSION['username'] it works fine - gives me what I expect... I set the $_SESSION['username'] = $username and very next line header('Location: index.php'); this is where the issues is it's loosing the session data and I can't figure out why... so here are the two files if someone can point me in the right direction.. index.php
<?php ob_start(); session_start();
if (!isset($_SESSION['username'])) {
echo print_r($_SESSION);
}else {
echo print_r($_SESSION);
}
?>

while ($row = mysqli_fetch_assoc($action)) {
if (mysqli_num_rows($action) === 1) {
$_SESSION['username'] = $username;
// echo "<br>";
// echo $_SESSION['username']; <-- this works echo's the username, if I remove header location redirect
header('Location: index.php');
exit();
}else {

First let me explain my code. This is later included in project_status.php] . In project_status.php] , I have included another file project_status_app.php which contains a HTML form.
<?php
include 'inc_fn_header_and_menu.php';
function includeFile($file,$variable) {
$var = $variable;
include($file);
}
if (isset($_GET['id']) && $_GET['id']!="") {
$pid = $_GET['id'];
$_SESSION['pidForApproval'] = $_GET['id'];
$query = 'SELECT * FROM `profile` WHERE pid ='.'\''.$pid.'\'';
$result=mysqli_query($db,$queryToRetrievePP) or die("There are no records to display ... \n" . mysqli_error());
foreach ($result as $row) {
$status = $row['status'];
}
}
...........some PHP and HTML code.......
<div id="customerPurchaseApprovalForm">
<?php
echo '<p>APPROVAL FOR CUSTOMER PURCHASE</p>';
$discountApprovalStatus = "Granted";
if ($discountApprovalStatus == "Granted") {
includeFile("project_status_app.php",$highestannualvalue);
} else {
//.........
}
In project_status_app.php I am attempting to retrieve pidForApproval from the $_SESSION array.
<?php
// put your code here UPDATE `pp` SET `customer_purchase_remarks` = 'hahaha' WHERE `pp`.`id` = 207;
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
include '../../inc/fastlogin.php';
$sql = "UPDATE pp SET customer_purchase_remarks ='{$_POST['remarkstxt']}' WHERE pp.pid='{$_SESSION['pidForApproval']}'";
$result = mysqli_query ( $fastdb, $sql ) ;
if (mysqli_affected_rows($fastdb) != 1) {
$_SESSION['err_cpa_rmks'] = "<p>Error while updating WHERE id='{$_SESSION['pidForApproval']}'</p>";
//echo "<p>Error while updating WHERE id='{$_POST['pidForApproval']}'</p>".mysqli_error($fastdb);
} else {
$_SESSION['suc_cpa_rmks'] = "<p>Records was updated successfully.</p>";
//echo "Records was updated successfully.";
}
header ("location: project_status.php?id="$_SESSION['pidForApproval']);
exit();
}
?>
When I load project_status.php, project_status_app.php is supposed to display the form. Once the user fills in the form the and the submit button has been pressed, the UPDATE statement is supposed to run and then it is supposed to navigate back to project_status.php?id=FA142. But the update is failing and the when the project_status.php is loaded back, the url looks like this http://localhost/fast/project_status.php?id= . The id is empty. It is supposed to be something like this http://localhost/fast/project_status.php?id=FA142. With the id being populated at the
header ("location: project_status.php?id=".$_SESSION['pidForApproval']);
Missing some information. Hello everyone, I am working on a form that is similar to a shopping cart system and I am thinking of creating a button that submits the checked value and saves them to a $_SESSION variable. And also a link that links to a cart.html that takes the values of a $_SESSION variable. I am have trouble figuring what tag/attribute should I use in order to achieve that.
Right now my code attached below submits the checked values to cart.html directly. However I want my submit button to save the checked box to a $_SESSION variable and STAY on the same page. And then I will implement a <a> to link to the cart.php.
I researched a little bit about this subject and I know it's somewhat related to ajax/jquery. I just wanted to know more about it from you guys. I appreciate your attention for reading the post and Thanks!
Below is the form that I currently have:
<form name= "finalForm" method="POST" action="cart.php">
<input type="Submit" name="finalSelected"/>
<?php foreach($FinalName as $key => $item) {?>
<tr>
<td><input type="checkbox" name="fSelected[]" value="<?php echo htmlspecialchars($FinalID[$key])?>" />
<?php echo "$FinalID[$key] & $item";?>
</td>
</tr>
<?php } ;?>
Below is the code for cart.php
<?php
require ('connect_db.php');
if(isset($_POST['finalSelected']))
{
if(!empty($_POST['fSelected']))
{
$chosen = $_POST['fSelected'];
foreach ($chosen as $item)
echo "aID selected: $item </br>";
$delimit = implode(", ", $chosen);
print_r($delimit);
}
}
if(isset($delimit))
{
$cartSQL = "SELECT * from article where aID in ($delimit)";
$cartQuery = mysqli_query($dbc, $cartSQL) or die (mysqli_error($dbc));
while($row = mysqli_fetch_array($cartQuery, MYSQLI_BOTH))
{
$aTitle[] = $row[ 'name' ];
}
}
?>
<table>
<?php if(isset($delimit)) {
$c=0; foreach($aTitle as $item) {?>
<tr>
<td>
<?php echo $aTitle[$c]; $c++;?>
</td>
</tr>
<?php }}?>

Hi all ! The $_Session has a url variable. Using a Dom how do I properly do: Code: [Select] html->load($_SESSION['variable']) I was thinking about breaking down the session to retrieve the value inside but I don't know how. Hi i have made a login in system for a website iam trying to make. after you log in im trying to display the members username via the $_session created in the check_login.php. but when i Echo or print_r the $_session all is get is "welcome array" its like its not passing any information via the $_session from page to page. here is my code thanks in advance. Check_login.php session_start(); // username and password sent from form $myusername=$_POST['myusername']; $mypassword=md5($_POST["mypassword"]); // To protect MySQL injection (more detail about MySQL injection) $myusername = stripslashes($myusername); $mypassword = stripslashes($mypassword); $myusername = mysql_real_escape_string($myusername); $mypassword = mysql_real_escape_string($mypassword); $sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'"; $result=mysql_query($sql); // Mysql_num_row is counting table row $count=mysql_num_rows($result); // If result matched $myusername and $mypassword, table row must be 1 row if($count==1){ // Register $myusername, $mypassword and redirect to file "login_success.php" $_SESSION["myusername"]==$myusername; $_SESSION["mypassword"]; header("location:login_success.php"); } else { echo "Wrong Username or Password"; } ?> login_success.php <? session_start(); if($_SESSION['myusername']="$myusername"){ header("location:main_login.php"); } Echo "welcome" . $_SESSION['$myusername']; ?> thanks PHP 5.3.3 I am trying to redirect a user (currently logged in) to a page where they are able to edit a posted comment. To keep things secure I am using a forms hidden input value to pass the {postID} to a redirect page Code: [Select] <form name="post_edit" method="post" action="post-edit-redirect.php" > <input type="hidden" name="local" id="local" value="<?php echo $row_rsPosts['postID']; ?>" /> <input type="image" src="../imgs/managepost.png" name="submit" /> </form> On the redirect page (simplified below) I am setting the {postID} in a SESSION before redirecting to the user to the page to edit their post with the new $_SESSION val for {postID} set. Code: [Select] session_start(); $id = $_REQUEST['local']; $_SESSION['postID']=$id; header("Location: edit-post.php"); This is working fine in every browser except IE (some one please just put an end to it), where when the edit-post.php page is reached the $_SESSION['postID'] is empty. If I regenerate the session ID from the redirect page as below IE then sets the SESSION ok. Code: [Select] session_start(); session_regenerate_id(); $id = $_REQUEST['local']; $_SESSION['postID']=$id; header("Location: edit-post.php"); However there should be no need to do this and would rather not if there is no need. Any help on why IE is not setting the SESSION is appreciated, and I hope I am not covering old ground here however I am unable to find a solution anywhere. - Cheers edited Hey, i was reading some code and i find this: if(stristr($_SESSION["s"]["user"]["asdasd"]),$someString) How the double/triple [] in $_SESSION works ? PS: I tryied to google it but it was kinda hard to search :X Thanks. For the last few hours I have been pulling my hair out on a session not storing when I moved from local host to my vps. I have been setting sessions like: $_SESSION['mydata'] = $variable; This works no problem on my wamp installation. However to get it to work on my vps, I have to store them like this $_SESSION[mydata] = $variable; Can someone please explain to me why this is the case? Just wanted to know if $_Session was a global thing or does php require cookies setup?
I assumed that I could do something like this:
PAGE: A.php
session_start();
$_Session['Cat'] = 'Meow';
// -----------------------
PAGE: B.php
if (isset($_Session['Cat']) && !empty($_Session['Cat'])){
echo $_Session['Cat'];
}
OUTPUT: Meow
// -----------------------
PAGE: C.php
if (isset($_Session['Cat']) && !empty($_Session['Cat'])){
echo $_Session['Cat'];
}
OUTPUT: Meow
I can't seem to get this to work.
Page: Handler.inc
// ========================================================= Session Log in / out
public function logon($username, $password){
if ($username == "admin" && $password == "coffee"){

echo 'IN SESSION LOGIN HANDLER';
echo $_SESSION['UserLogged'];
}
}
public function logout(){
$_SESSION['USER_STATUS'] = '0';
echo 'IN SESSION LOGOUT HANDLER';
session_destroy();
//session_unset();
}

$username = $_POST['username'];
$password = $_POST['password'];
echo $handler->logon($username, $password);
}
<LOGIN FORM CODE>
}else{
if (isset($_SESSION['USER_STATUS']) && !empty($_SESSION['USER_STATUS']) || $_SESSION['USER_STATUS'] == 1){
echo 'Session name: '. $_SESSION['USER_STATUS'];
}
if (isset($_POST['btn_logout']) && !empty($_POST['btn_logout'])){
$handler->logout();
echo '<br />Logged out<br />';
}

}
Could someone point me in the right direction please. It does not seem to hold its session.
I have parts of my webpage protected with the following Code: [Select] session_start(); if(!isset($_SESSION['myusername'])){ header("Location:login.php"); } else { $username = $_SESSION['myusername']; } How secure is this? The goal is so people who don't have access to the page (don't have a login account) cannot get access Thanks for any tips // SESSION TEST if ($_SESSION['username']) { require_once("../mysql.php"); // Find Username from Session ID // Find Username from ID $finduser="SELECT username FROM users WHERE id='$_SESSION[username];'"; $finduserquery=mysql_query($finduser)or die(mysql_error()); $userfetch = mysql_fetch_array($finduserquery); // Set Username Variable $userfromid = $userfetch['username']; echo "lol" . ucwords($userfromid); } else { } Everytime I load this page more than once when logged in, it seems to turn the variable blank. Therefore making the user not be able to view other pages that use a session. Help?

Can somebody help me? Thank you! Hi i'm new to the forum and i'm wondering if anyone here could help me out with the problem i'm having. the script i have uses $_SESSION['userid'] = $users['id']; and i'm not exactly sure how to read that .. any information would be helpful. thanks in advance Hiya, I'm quite new to php. My script was working fine till I transferred to a new host. The login system doesn't seem to register the $_SESSION 'userid' variable, so the proper page won't load because it thinks I'm not logged in. login.php - processes the login information Code: [Select] <?php session_start(); include('functions.php'); connect(); // note: session_start needs to be on every document apart // from index.php, login.php and register.php $username = protect($_POST['username']); $password = protect($_POST['password']); // the password and username from the inputs are stored in variables if ($username&&$password) { // if both the username and password variables are true $query = mysql_query("SELECT * FROM users WHERE username='$username'"); $numrow = mysql_num_rows($query); if ($numrow!=0) { // if $numrow does not equal nothing while ($row = mysql_fetch_assoc($query)) { $userid = $row['userid']; $dbusername = $row['username']; $dbpassword = $row['password']; } if ($username==$dbusername&&md5($password)==$dbpassword) { // $password gets encrypted so it can be checked on the database password $_SESSION['username'] = $username; $_SESSION['userid'] = $userid; // used for sessions knowing who is logged in header("Location:main.php"); // redirects to main.php page after successful login } else { echo "Incorrect password"; } } else { ?> <html> <head> <title>University Crusade</title> <link rel="stylesheet" href="css/style.css" type="text/css" media="screen"> <meta name="viewport" content="width=device-width, minimum-scale=1,maximum-scale=1, user-scalable=no"> </head> <body> <div id="wrapper"> <?php die (" That account doesn't exist...<br /><a href=\"index.php\">try again,</a> <a href=\"register.php\">or register an account.</a> "); } } else { die("Please enter a username and password"); } ?> </div> <div id="footer"> </div> </body> </html> and the main.php - after login.php it takes the user here Code: [Select] <?php session_start(); include('functions.php'); connect(); ?> <html> <head> <title>University Crusade</title> <link rel="stylesheet" href="css/new.css" type="text/css" media="screen"> <meta name="viewport" content="width=device-width, minimum-scale=1,maximum-scale=1, user-scalable=no"> </head> <body> <?php if (isset($_SESSION['userid'])) { include('safe.php'); ?> <ul id="tab-nav"> <li><a href="stats.php" id="tab-character">CHARACTER</a></li> <li><a href="games.php" id="tab-games">GAMES</a></li> <li><a href="account.php" id="tab-account">ACCOUNT</a></li> </ul> <div id="wrapper"> <h2 id="name">Hello, <?php echo $_SESSION['username'] ?>!</h2> <p> Welcome to UNIVERSITY CRUSADE the fantasy-themed pervasive web game! </p> <p> To start playing, begin with clicking the "games" button at the top of the screen, from there choose a challenge and follow the instructions </p> <p> What are the other buttons for?

I, for some unknown reason, decided to attempt to build my first social networking website for my senior project. I am sort of a dumb dumb when it comes to PHP. For what I am currently working on now I need to display "members" that go to the same "school" and start in the same "semester" according to whomever is currently logged in. I understand $_SESSION['userid'] = mysql_insert_id(); is tracking the current user, but how would I track other information attached to that current user. The "school" and "semester" are tracked within tables outside of the "user" table. Any help at all would be awesome. If you need anymore information let me know. Thanks a trizillion. I just got through a server problem with a variable named $_SESSION['id'] What would happen was when I loaded a mysql request with id in it (usually what i name the main key in a table) it would overwrite the value in the $_SESSION without specifically asking it to ie $_SESSION['id']=$id; This was on an acenet server I have the same thing on a bluehost server and wampserver and never had a problem What I did on acenet was rename $_SESSION['id'] when declaring it to $_SESSION['usernumber'] and all my issues stopped Anyone know why? Is it a acenet problem? My problem is fixed im just wondering if anyone has had a similar issue????? Hi all, I'm in trouble with a strange problem. At the system login a script sets a $_SESSION['status'], this keeps user status for admin (a), user (u), and so on... In another part of the system I need to post a value also called 'status': Code: [Select] <input value="N" type="hidden" name="status"/> and this 'status' value has nothing to do with 'status' session. The problem is that when I post the value 'N' it overwrite the session value, crashing the system then. The most strange is that on the localhost the problem does not happen, it only occurs on the server. Any clue? Thankx Danilo Jr. Is there an equivalent to * (any) in a $_SESSION? Something like this: foreach ($_SESSION['cart']['content'][*]['Large'] as $content) { |
