PHP - Session Time Out Code Behaving Badly?
I have the following session timeout code which should redirect users of a website to a page (session_expired.php) which prints out a message telling the user that his session has expired. I include this code at the top of every page in the website, that requires user authentication. Code: [Select]
<?php //address error handling ini_set ('display_errors', 1); error_reporting (E_ALL & ~E_NOTICE); if (isset($_SESSION['LAST_ACTIVITY']) && (time() - $_SESSION['LAST_ACTIVITY'] > 1800)) { // last request was more than 30 minates ago session_destroy(); // destroy session data in storage session_unset(); // unset $_SESSION variable for the runtime header("location: session_expired.php"); } $_SESSION['LAST_ACTIVITY'] = time(); // update last activity time stamp ?> The session_expired.php page which I will include below, has a login link, which takes the user to a login page (access_denied.php) Code: [Select] <?php //address error handling ini_set ('display_errors', 1); error_reporting (E_ALL & ~E_NOTICE); //Set the page title before the header file $title = 'Session Expired'; require ('header.php'); //need the header ?> <div id="content" class=""> <div id="left_content" class=""> </div> <!--closes left content--> <div id="right_content" class=""> <div id= "right_content_inner_border"> <h5 style ="position:relative;left:660px;top:1px;"> <a style="text-decoration:none" href="access_denied.php">[Login]</a> </h5> <h3 style ="position:relative;left:110px;top:100px; font-color:blue;"> You Session Expired Due to Inactivity! </h3> </div> <!--closes right content inner border--> </div> <!--closes right content--> </div> <!--closes content--> <?php require ('footer.php'); //need the footer ?> Now here lies the problem. When i set the session timeout to say 60 seconds to test the code, everything seems to work perfectly. The authenticated page gets redirected to session_expired.php after 1 minute and when the user clicks on the login link, he is taken back to the login page(access_denied.php). However, when I replace the time with 1800 seconds, the page notice that when I leave the page idle for JUST about 5 minutes, it gets redirected NOT even to the expected session_expired.php page but strangely, directly to the login page(access_denied.php). What could be going wrong here? Any hint is appreciated. Similar TutorialsHi I am developing a e-commerce website. The user logs in and buy a product when he checkout the page will redirect to the payment gateway. After the payment is completed it will return back to my website. This is ok. But when it is returning back the session maintained in my website get lost. This happen only for the first time. If the user again logged in and checkout the process works good and the session is maintaining. Why does the session lost for first time. I used session_start() in all the pages.. I cannot find the solutions. Kindly help.. Regards P.Balakrishnan how can i set a session to expire after a set amount of time, say 1 hour. i'm using the following code to create my session, but i dont know what i need to add to make it expire $_SESSION['pageviewsid'.$id] = $new; $new is the result from a calculation and $id is the page id from the URL using $_GET Hi all, I'm trying to increase the server default php session timeout from 1hour to 3hours. I don't have access to my php.ini but can use .htaccess. Is the following the correct way to do this? in the .htaccess add the line: php_value session.gc_maxlifetime 10800 Or would I be better off including the following after every session start() on everypage: Code: [Select] ini_set("session.gc_maxlifetime","10800"); thanks! Hello guys, I am new to PHP. I need some help. I am trying to build a web app, in which I have login functionality. I want to keep the logged in user session active for around 3-4 months. But in my case as soon as I close the browser, session data is lost and I need to login again. Can anyone help me with this. Hello everyone, I've searched these forums for a while now trying to resolve a problem that I have with my sessions timing out before I would like them to, but I've only gotten confused about it. I've read about changing some settings or adding code in my php.ini file but I have no idea what I'm doing when it comes to that. I'm starting the session simply by having session_start(); at the top of each of my pages. I'm including a copy of my entire php.ini file here so that you can see what I have already. Can someone please help me to figure out what I would need to do to make my sessions last at least 8 hours? Thanks in advance. Here's my php.ini file: Code: [Select] register_globals = off allow_url_fopen = off expose_php = Off max_input_time = 60 variables_order = "EGPCS" extension_dir = ./ upload_tmp_dir = /tmp precision = 12 SMTP = relay-hosting.secureserver.net url_rewriter.tags = "a=href,area=href,frame=src,input=src,form=,fieldset=" ; Only uncomment zend optimizer lines if your application requires Zend Optimizer support ;[Zend] ;zend_optimizer.optimization_level=15 ;zend_extension_manager.optimizer=/usr/local/Zend/lib/Optimizer-3.3.3 ;zend_extension_manager.optimizer_ts=/usr/local/Zend/lib/Optimizer_TS-3.3.3 ;zend_extension=/usr/local/Zend/lib/Optimizer-3.3.3/ZendExtensionManager.so ;zend_extension_ts=/usr/local/Zend/lib/Optimizer_TS-3.3.3/ZendExtensionManager_TS.so ; -- Be very careful to not to disable a function which might be needed! ; -- Uncomment the following lines to increase the security of your PHP site. ;disable_functions = "highlight_file,ini_alter,ini_restore,openlog,passthru, ; phpinfo, exec, system, dl, fsockopen, set_time_limit, ; popen, proc_open, proc_nice,shell_exec,show_source,symlink" Is it possible to set a certain session to time out after say 2 minutes. I want to lock a person from seeing a page for 2 minutes then destroy the session yet keep the primary session and still keep dpoing what they were doing? Just curious. Thanks, As my title said the question, i want to destroy my session after a particular time if user is being ideal.. currently i am using this code to define my session: Code: [Select] session_start(); // Check, if username session is NOT set then this page will jump to login page if (!isset($_SESSION['myusername'])) { header('Location: admin.php'); } Can the byte order mark have an effect on the stylesheet? I was editing a php file and as soon as I saved it, the entire layout of my website was distorted, well in IE, but both browsers the font size has increased I have never came across something like this in years. I think I changed the encoding but it may of placed a BOM on every page. I have no idea how to rectify this... anyhelp would be nice! http://team-x1.co.uk/site/ In order to keep data on the browser , so I use session to keep post data. I try to turn the page. I does not work , I do not know how to fix it. Please tell me .

You can find the script here and log in with the username "test" and the password "testing". I'm not sure what more information I should add. Thanks, Cameron Dear Friends I want to execute a php code when my session has been destroy or demoinshed, I need a help regarding this kindly help me. Best Regards Habib Basically I need to select some rows from my database that have been posted in the last 24 hours. So since my date is stored from the values of the time() function I want to do a query to get the results only greater than a certain time code. So if I lets say have this value: 1321184384, what can I subtract to go back 24 hours? Ok I have the following as part of a login script which is supposed to set a cookie upon successful login [php] if (mysql_num_rows($LoginResult) > 0) { $UserID = mysql_result($LoginResult, 0, 'user_id'); $Id = uniqid(); $IdRes = mysql_query("UPDATE ".MEMBER_LOGIN_TABLE." SET `unique_id`={$Id} WHERE user_id='{$UserID}", $db); setcookie('RAYTH_MEMBER_ID', $Id, time()+2592000); Echo "Logged In. Click <a href='index.php?act=idx'>Here</a> to Continue.<br>Note: If you click continue and you are not logged in please ensure cookies are enabled!"; } [/cookie] However when I log in I get: Code: [Select] Warning: Cannot modify header information - headers already sent by (output started at /home/rayth/public_html/style.php:1) in /home/rayth/public_html/login.php on line 38 Logged In. Click Here to Continue. Note: If you click continue and you are not logged in please ensure cookies are enabled! Line 38 is the setcookie() line. Can someone shed light on where I am going wrong here? I have several pages on my site using the exact same code at the very top, which works fine except for one page: <?php include_once("../members/dbinfo.php"); The top of dbinfo looks like this: <?php session_start(); And then the connection strings for the database However it is giving me this error on this one page: Quote Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at C:\Inetpub\WebSites\premierathome_com\products\FrenchTalkingDictionary.php:1) in C:\Inetpub\WebSites\premierathome_com\members\dbinfo.php on line 1 Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at C:\Inetpub\WebSites\premierathome_com\products\FrenchTalkingDictionary.php:1) in C:\Inetpub\WebSites\premierathome_com\members\dbinfo.php on line 1 Now the session does actually start and doesn't prevent anything from working, I just get those messages. I'm at a loss as to why a different page with the exact same code, save for searching the database for a different product version would have this problem. I have had this code in place as well which works fine on other pages but doesn't help my problem at all: if(!isset($_SESSION['OK'])){ session_start(); } OK being a variable I set up during log in. I'm at a loss, is anyone able to help me out with this? Hi ,
I try to change a PHP code for a booking program without succes. Now the time set is from 00.00 - 24.00hours but it must be fixed on 15.00H ( dropoff) and 11.00H (pick-up). Can someone help me please ?
