PHP - Help Ending A Php Session When A Page Is Closed
Hi Everyone,
I wonder if somebody could help me. I have been at this for hours and am really struggling. I have a timer which I have set up for a quiz. The quiz opens in a javascript shadow box. When the quiz is opened a session variable for the timer is set up to keep track of the time. What I need is for this session variable to end when the shadow box is closed. I have a onClose hook to peform actions when the shadow box is closed which is in javascript. Obviously I cannot end the session variable in the javascript function due to js being client side and php being server side. Has anyone any suggestions how I can resolve this issue. I need to end this session variable as if the user exits the quiz and then selects another quiz to do the timer uses the current time session rather than assigning the new time value for that particular quiz. Thanks in advance. Edd Similar TutorialsHello, I have the $_session code working, but after I destroy the session and I am asked to log in again, my browser doesn't ask me for my password and just logs me in. I don't understand because I have destroyed my session and I have deleted the data in $_SESSION and I have deleted the info in the cookie so it shouldn't log me in automatically. I thought it was something in my browser, but I erased my history and I never saved any password. Here's my code: This is the welcome page
<?php
require_once 'login.php';
$connection = new mysqli($db_hostname, $db_username, $db_password, $db_database);
if ($connection->connect_error) die($connection->connect_error);
if (isset($_SERVER['PHP_AUTH_USER']) && isset($_SERVER['PHP_AUTH_PW']))
{
$un_temp = mysql_entities_fix_string($connection, $_SERVER['PHP_AUTH_USER']);
$pw_temp = mysql_entities_fix_string($connection, $_SERVER['PHP_AUTH_PW']);
$query = "SELECT * FROM users WHERE username='$un_temp'";
$result = $connection->query($query);
if (!$result) die($connection->error);
elseif ($result->num_rows)
{
$row = $result->fetch_array(MYSQLI_NUM);
$result->close();
$salt1 = "qm&h*";
$salt2 = "pg!@";
$token = hash('ripemd128', "$salt1$pw_temp$salt2");
if ($token == $row[3])
{
session_start();
$_SESSION['username'] = $un_temp;
$_SESSION['password'] = $pw_temp;
$_SESSION['forename'] = $row[0];
$_SESSION['surname'] = $row[1];
echo "$row[0] $row[1] : Hi $row[0], you are now logged in as '$row[2]'";
die("<p><a href=continue.php>Click here to continue</a></p>");
}
else die("Invalid username/password combination");
}
else die("Invalid username/password combination");
}
else
{
header('WWW-Authenticate: Basic realm="Restricted Section"');
header('HTTP/1.0 401 Unauthorized');
die("Please enter your username and password");
}
$connection->close();
function mysql_entities_fix_string($connection, $string)
{
return htmlentities(mysql_fix_string($connection, $string));
}
function mysql_fix_string($connection, $string)
{
if (get_magic_quotes_gpc()) $string = stripslashes($string);
return $connection->real_escape_string($string);
}
?>
and this is the other page:
<?php
session_start();
if(isset($_SESSION['username']))
{
$username = $_SESSION['username'];
$password = $_SESSION['password'];
$forename = $_SESSION['forename'];
$surname = $_SESSION['surname'];
destroy_session_and_data();
echo "Welcome back $forename. <br>
Your full name is $forename $surname.<br>
Your username is '$username'
and your password is '$password'.";
}
else echo "Please <a href='authenticate2.php'>Click here</a> to log in.";
function destroy_session_and_data()
{
$_SESSION = array();
setcookie(session_name(), '', time() - 2592000,'/');
session_destroy();
}
?>
When I type the website in i first get prompt to enter my password, when I am authenticated the webpage says: You are now logged in click here to continue. When I do I am directed to another page which confirms that I am still logged in. Then I press refresh and the webpage asks me to "Click here to log in". I do, but it doesn't ask me for my password again. Why? My personal info should be destroyed. Thank you for responding. It's greatly appreciated
Hello, How do I get a user's session destroyed when he closes his browser? Thanks in advance Hey All, I have a sessions table that is used to see if a user is online. It only gets deleted when they click the Logout button. What I need to do is have it so it gets deleted even if they close the browser. Should I add a column in the sessions table with a time stamp and check on each page for every user to make sure its great than 30 min? Is there a better way to do this, without so many queries? Thanks Ok this is some noob question here I have a page that has few separate pieces of php code embeded within html code. Each piece is separated with Code: [Select] <?php ... ?> tags, everything works fine. I need to assign a variable in first (from the top) piece of php code. Then I want to be able to use that variable in all others php pieces across this same page.... I searched and searched and first tried to do it like : First piece: Code: [Select] <?php function id() { $id="blah"; } ?> Second piece : Code: [Select] <?php id(); ... echo $id; ?> didn't work, then I tried First place: Code: [Select] <?php $id="blah"; function id() { global $id; } ?> Second piece : Code: [Select] <?php echo $id; ?> After struggling and reading for few days all about global, static, and regular variables i finally decided to ask professionals to help.... please let me know if you need me to make the question description more clear or smn Some code from my pages ,
Page1 ( Redirecting page )
<html> <title>login_redirect.</title> body> <form name="redirect" action="http://mysite/page2.php" method="post"> <input type="hidden" name="mac" value="$(mac)"> </form> <script language="JavaScript"> <!-- document.redirect.submit(); //--> </script> </body> </html>Page 2 ( select product )
<?php
session_start();
ini_set('display_errors',1);
error_reporting(E_ALL);
include '../lib/config.php';
include '../lib/opendb.php';
// get user mac adres from redirect post page1
$_SESSION['macid'] = $_POST['mac'];
// set $macid for other use ( maybe not needed, am learning )
$macid = $_SESSION['macid'];
// echo $macid does show mac adress, so variable is not empty here
if (!empty($_POST["submit"]))
{
$product_choice = $_POST['accounttype'];
$query= "SELECT AccountIndex, AccountCost, AccountName FROM AccountTypes WHERE AccountIndex='$product_choice'";
$result = mysql_query($query) or die('Query failed. ' . mysql_error());
while($row = mysql_fetch_array($result))
{
$_SESSION['AccountIndex'] = $row['AccountIndex'];
$_SESSION['AccountCost'] = $row['AccountCost'];
$_SESSION['AccountName'] = $row['AccountName'];
}
header('Location: page3.php');
}
// did leave out the other/html/form stuff here
Page 3 ( show Session variables )
<?php
ini_set('display_errors',1);
error_reporting(E_ALL);
session_start();
print_r($_SESSION);
?>
Now, on page 3 i do see the right session varables, only the "macid" is empty.
why ?
ONE of my SESSION values isn't remaining after login while others do. This works fine on my localhost, it's on the live site that there is a problem and it just started yesterday. Before that it worked great. Out of the four SESSIONs made I can only echo three values on other pages, member id the most important doesn't transfered to other pages Notes: all these files are in the same folder, there is a SESSION started for the member id on the login page, you can see that it is used in the redirect below and the redirect works fine with the redirect going to the correct page " $home/member/index.php?user=$id_mem " Here is the login page // Here's the basic login page info <?php # login.php session_start(); ob_start() ...connect to db & header called... ...Form validation..... if ($e && $p) { // If everything's OK. // Query the database: $q = "SELECT id_mem, display_name, mem_group FROM sn_members WHERE (email='$e' AND password=SHA1('$p')) AND active IS NULL"; $r = mysqli_query ($dbc, $q) or trigger_error("Query: $q\n<br />MySQL Error: " . mysqli_error($dbc)); // or die("Error: ".mysqli_error($dbc)); if (@mysqli_num_rows($r) == 1) { // If a match was made. // Register the values & redirect: // Give SELECTED elements a session $_SESSION = mysqli_fetch_array ($r, MYSQLI_ASSOC); $_SESSION['agent'] = md5($_SERVER['HTTP_USER_AGENT']); mysqli_free_result($r); // Update db for last login $id_mem = $_SESSION['id_mem']; // <<< SESSION member id has a value here because it's used in the redirect below $ip = $_SERVER['REMOTE_ADDR']; // Get ip address of person logging in $q = "UPDATE sn_members SET last_login = Now(), ip = '$ip' WHERE id_mem = '$id_mem' LIMIT 1"; $r = mysqli_query ($dbc, $q) or trigger_error("Query: $q\n<br />MySQL Error: " . mysqli_error($dbc)); header("Location: $home/member/index.php?user=$id_mem"); exit(); // Quit the script. } ?> Here is the main page that a user would be redirect to above <?php // /member/ all member info is through this folder session_start(); ob_start(); if (isset($_GET['user']) && is_numeric($_GET['user'])) { $user = $_GET['user']; $user = $user; if ($user < 0) { header("Location: $home/index.php"); exit(); } } if ((!isset($_SESSION['id_mem'])) && (!isset($_SESSION['agent']) OR ($_SESSION['agent'] != md5($_SERVER['HTTP_USER_AGENT'])))){ // If not a logged in member redirect header("Location: $home/index.php"); exit(); // Quit the script. } ?> Thanks in advance for the help SJ Hey guys. I am trying to strip everything between a key phrase and ending tag but for some reason it is not working. I always get blank data. I've tried many different ways but no luck.
basically I have a script that connect to imap and store emails into MySQL as service tickets. works great but I am trying to strip everything except for user reply because currently if a user reply to an email it re-inserts the entire email into MySQL. I added a key phrase at the top of all outgoing emails .
1. structure looks like this.
--Reply below this line to respond--
------------------------------------------------------------------------------------------------
Email body message...
2. When replying to the message it becomes
New Message reply......
--Reply below this line to respond--
old message body.
3. so I would only like to insert the new reply message only.
This is what I got so far.
$message=strip_tags($message, "<br><div><p><u><hr></section>");
$message=preg_replace("</p>", "br /", $message); $message=preg_replace('#--REPLY above this line to respond--(.*?)</section>)#s', ' ', $message); $message=clean("<br/><hr><u>Received On $rep_date / $from_email</u><br><br/>$message"); it inserts the "Received On date and From but $message is blank. If i remove $message=preg_replace('#--REPLY above this line to respond--(.*?)</section>)#s', ' ', $message); it inserts the entire email Any suggestion on what i am doing wrong? thank you all very much.

Hi, I am trying to figure out how to stop my script from offering a discount when the date that is listed passes by. It seems to always 'reset' itself even after the 15th of the month...I want it to stop after April 15...This is what I had, can anyone assist? Thank you in advance for your help! Jennifer Code: [Select] } if(date("n") < 15) { $before = $cost*.05; $before = round($before,2); $cost = $cost-$before; } Part of my page is taken from external webpages by preg_match. Since It is a partial section, it contains incomplete tags such as <div>, <span>, etc. Thus, they mix up with my entire page and my </div>, </span> are used for the incomplete tags in the borrowed section. How I can end such tags? or separate this section from the main codes (I mean having an isolated section)? I have my php pages set up like this: 1. log in with login.php 2. that sends you to main.php 3. in main.php, there are links to page-a.php, page-b.php, page-c.php, etc. when you type in a password at login.php, it passes your input to main.php. the correct password is hardcoded in main.php. if it matches, a session variable is set, which should be able to be used on page-a.php, page-b.php, page-c.php, etc. to verify that whoever accesses those pages has gone through the login process. if the session variable doesn't match (or null) the user is redirected to the login page. also the session variable is checked (recursively) when accessing main.php, just like the other pages. the problem is, it's as if each page starts over. the session variable does not make it beyond the page that sets it. it should be passed on to the next page but it's not. I used an echo statement in page-a.php to verify and rem'd out the rest of the code. no echo because session value is null, page goes on to load the html. without the code rem'd out it redirects the user to login.php. code: LOGIN.PHP <? session_start(); if(isset($_SESSION['aaa'])) unset($_SESSION['aaa']); ?> <html> <head> <title>title</title> </head> <body> <table width="400" align="center" border="0" bordercolor="#000099" bordercolordark="#000066" bordercolorlight="#6666FF"> <tr bgcolor="#B0C4DE"> <td> <form action="main.php" method="POST"> <p align="center"><strong><font size="2" face="Verdana, Arial, Helvetica, sans-serif" color="#FFFFFF"><br> Password</font></strong> <input name="pwfield" type="password" value size="20" maxlength=20> <input type="submit" value="Login"></p> </form> </td></tr></table> </body></html> MAIN.PHP <? if ($_SESSION['aaa']!="abcdef") { $password="twinkies"; if ($_POST["pwfield"]==$password) $_SESSION['aaa']="abcdef"; // successful login else {header("Location: login.php"); exit();} } ?> <html> <head> <title>title</title> </head> <body> <a href="page-a.php">Page A</a> <a href="page-b.php">Page B</a> <a href="page-c.php">Page C</a> </body></html> PAGE-A.PHP <? echo $_SESSION['aaa']; //if ($_SESSION['aaa']!="abcdef") //header("Location: login.php"); //exit(); ?> <html> <head> <title>title</title> </head> <body> ... hey guys i'am newb in php and i'am doing some algorithm in php, in some codes i need to use session but in that particular page the code does not know if session_start() has been called or not. wonder to if there is anyway that i can get if session is started or not in my code? thanks in advance I'm building a login page that then redirects to a new page. But it seems the session isn't working. But I don't know much about sessions, so I'm not sure what I might be doing wrong. The login page sets the session with this code: Code: [Select] // Fetch the result - This will tell us whether this user exists $userExists = mysql_fetch_assoc($doQuery); // If user exists log them in if($userExists){ mysql_free_result($doQuery); mysql_close(); // Set the SESSION variables $_SESSION['first_name'] = $userExists['first_name']; $_SESSION['id'] = $userExists['id']; The page that it redirects to is this: Code: [Select] <?php session_start(); if(isset($_SESSION['id'])) { echo "<html><body><p> You are now logged in,{$_SESSION['ID']}.</p>"; } else { echo 'something went wrong'; exit(); } ob_end_flush(); ?> Hi, I have a user/password protected page that displays a list of clients. When clicking on them you're redirected to the client record update page. This is how I am linking to taht page now: Code: [Select] <a href="DIST_clientes_update.php?id_cliente=<?php echo $row_clients_RS['id_cliente']; ?>The problem with this is that the client id is appended to the url and so if the user chnges it will be able to access records from a different user...and I dont want that. So I have created a session: Code: [Select] $_SESSION["idCliente"] = $row_clients_RS['id_cliente'];but how do I pass it to the update page without showing in the url? Thanks Hi. I have problem and I would like to know if anyone here has any ideas on how to fix it. My home page is where my log in form resides. If I leave the home page to browse other pages of my site I want to stay logged in. However, when I return to the home page I see the log in form. The log in form should not be there if I already logged in. Instead I should see the welcome message. Which does appear after loggin in but does not stay on the home page when I leave the page and come back. Code: [Select] <?php //Starts the PHP Sesssion session_start(); //Includes the MYSLQ Connection Info from another PHP Page include ('spartacus_mysql.php'); //Submits Log In Info to Database and encrypts Password if (isset ($_POST['loginsubmit'])) { $username = mysql_escape_string($_POST['username']); $userpassword = mysql_escape_string(md5($_POST['userpassword'])); if (!empty ($username) && !empty ($userpassword)) { //Runs Query to Selects the Username and Password from the Database $sql = mysql_query ("SELECT * FROM users WHERE username='".$username."'

$uprmastmt = $dbh->prepare("UPDATE rma SET r_nr = '$rmanr' WHERE r_id = ?");
$uprmastmt->bindParam(1, $lastid);
$uprmastmt->execute();
But i keep getting a new rmanr every time i submit... Could it be that my form submit reset my SESSION?
OK, I'm nearing the end of a very long chat project and I have one last hurdle to jump, I've saved this task to the near end because I thought it would be a problem as I have no idea what to do or where to start. The problem is exactly what is said in the subject title. I have looked into JavaScript options such as "onbeforeunload" but that is just BAD. The login is controlled by sessions, so when the user closes the browser, the session is ended, but data in the database says different, cookies are not an option I'm afraid. I've had an idea that if I create a special account (or a few) and always leave these accounts logged in, they can check if a user has been inactive for a certain period of time, and then run queries to change things, I know this sound odd but maybe I will not have to create these accounts but general accounts that people make will be able to do this for me, without them even knowing. Please help, any ideas, suggestions, logic or methods that you think will help will be great. Thanks. |
