PHP - Session Unset Not Working
Code: [Select]
$itemlisted = $_POST['itemlisted']; if ($itemlisted) { unset($_SESSION['items'][$itemlisted]); } it should work i don't get it. $itemlisted is 1... so it should delete [1] in the array. any idea why it's not working? Similar TutorialsI have one entity: $_SESSION['order']['content']['lol'] I then unset this entity: unset($_SESSION['order']['content']['lol']); I then try to unset the following as it is now empty (because I removed "lol"), buts its not working: if (empty($_SESSION['order']['content'])) { unset($_SESSION['order']['content']); } Does anyone know why and how I can go about getting it to unset? Afternoon, I've hit a brick wall, and I'd like someone to point out where I'm going wrong here as I can't for the life of me think of whats amiss. As it is, I'm trying to set a message to the user in session form, so the function is called passing the error ID. As you can see below, it finds it and assigns it to the private variable within the class. Code: [Select] <?php public function set($name){ // Check if the message is available... if(array_key_exists($name, $this->errors)){ // Set it. $_SESSION['cM'] = $this->errors[$name][0]; } else { $_SESSION['cM'] = 'TEST'; } } ?> To then return the message, the function is simply called using the below function which should return the error? Now, when I don't unset the session in anyway shape or form the message is displayed but when I do unset it, no message appears. I was under the impression that as I had already assigned the contents of the session to the $message variable that the session itself was then useless and as such I could then unset it for later use. But apparently not? Code: [Select] <?php public function get(){ // Is something set? if(isset($_SESSION['cM'])){ // Yes, into a variable! $message = $_SESSION['cM']; // Unset the session for later use. //unset($GLOBALS['cM']); - Doesnt make any difference. //$_SESSION['cM'] = false; - Doesnt make any difference. //unset($_SESSION['cM']); - Doesnt make any difference. // Return the message. $f = "<p style=\"color:green\">"; $f.= $message; $f.= "</p>"; return $f; } // No, Return false then to stop an error appearing. return false; } ?> As you can see I have tried unsetting the global variable, just session itself and clearing the session but to no avail. Any ideas? on page load pop up comes for selecting tv or movies (session is started in conn.php) if tv is selected session['select'] = 'tv_sotime' same for movies Now i want to change the selection I kept a link 'CHANGE' for selection i will unset session['select'] by passing variable on session.php but when i load /entertainment.php the pop up should not come Thank U... index.php Code: [Select] <? include("conn.php"); //require('_drawrating.php'); $pagename="Entertainment"; ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title><?=$settings->ScriptName?> | <?=$pagename?></title> <link rel="shortcut icon" href="images/favicon.ico" /> <link rel="shortcut icon" type="images/png" href="images/favicon.png" /> <link rel="shortcut icon" type="images/png" href="images/favicon.gif" /> <link rel="stylesheet" href="style.css" type="text/css" media="all" /> <link rel="stylesheet" href="css/cnelstyle.css" type="text/css" media="all" /> <link media="screen" rel="stylesheet" href="css/colorbox.css" /> <script src="js/jquerylatestmin.js" type="text/javascript"></script> <script src="js/jquery.colorbox-min.js" type="text/javascript"></script> <script type="text/javascript"> $(function() { $(window).bind('load', function(e) { $.colorbox({ 'width' : 300, 'height' : 130, 'transitionIn' : 'none', 'transitionOut' : 'elastic', 'centerOnScroll' : 'true', 'overlayOpacity' : 0.2, 'overlayColor' : '#000', 'modal' : 'true', href:"select.php"}); }); }); </script> </head> <body> <? //require_once("fb.php")?> <div id="wrap"> <? include('header.php'); include("session.php"); ?> <div class="wraper"> <div class="middle"> <div class="ad"><?=stripslashes($adsense->Ads7)?></div> </div> <div class="clr"></div> </div> </div> <div class="footer"> <div class="wraper"> <?php include("footer.php"); ?> </div> </div> </body> </html> tv_sotime.php Code: [Select] <?php include("conn.php"); $pagename="TV SHOWTIME"; $_SESSION['select'] = 'tv_sotime'; ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title> <?=$settings->ScriptName?> | <?=$pagename?> </title> <link rel="shortcut icon" href="images/favicon.ico" /> <link rel="shortcut icon" type="images/png" href="images/favicon.png" /> <link rel="shortcut icon" type="images/png" href="images/favicon.gif" /> <link rel="stylesheet" href="css/cnelstyle.css" type="text/css" media="all" /> <link rel="stylesheet" href="style.css" type="text/css" media="all" /> <link rel="stylesheet" href="jscss/main.css" /> <script type="text/javascript" src="jscss/jquery-1.3.2.min.js"></script> <script type="text/javascript" src="jscss/main.js"></script> </head> <body> <? //include("customjqmodalbox.php"); require_once("fb.php"); ?> <div id="wrap"> <? include('header.php')?> <div class="wraper"> <div class="middle"> <div class="middle_content"><a href="session.php?curr=c">Change</a></div> <div id="page"> <ul class="mytabs" id="tabs"> <li class="title"> <h2><strong>What's on Today?</strong></h2> <? //date('l M d Y')?> </li> <!-- <li class="todaydate"> <h2></h2> </li>--> <li class="current"><a href="tab-1.html">Movies</a></li> <li><a href="tab-2.html">Reality</a></li> <li><a href="tab-3.html">Sports</a></li> </ul> <div class="mytabs-container" id="tabs-container"> Loading... </div> </div> <!-- page --> <div class="ad"> <?=stripslashes($adsense->Ads7)?> </div> <div class="ss"> <h3 id="cat_head">Categories</h3> <ul> <li><a href="#">Drama</a></li> <li><a href="#">TV Programs</a></li> <li><a href="#">Special Programs for special Day</a></li> </ul> <img src="images/cineaxis.png" alt="" /> </div> </div> </div> <div class="clr"></div> </div> </div> <!-- warp --> <!--<div class="fb-like-box" data-href="http://www.facebook.com/CineAxis" data-width="198" data-height="274" data-show-faces="true" data-border-color="#E8E8E8" data-stream="false" data-header="false"> </div>--> <div class="footer"> <div class="wraper"> <?php include("footer.php"); ?> </div> </div> </body> </html> Code: [Select] <? include("conn.php"); //session_start(); if(isset($_GET['curr']) == 'c') { unset($_SESSION['select']); //session_destroy(); header("Location:index.php"); } if(isset($_SESSION['select'])) { if($_SESSION['select'] == 'tv_sotime') { $page = 'tv_sotime.php'; header("Location:$page"); } if($_SESSION['select'] == 'movie_sotime') { $page2 = 'movie_sotime.php'; header("Location:$page2"); } } ?> Hi All, When a user saves the page, I want to have the page refresh to show the new record and then have a message saying "Success!" or something like that. The only way I know how to do this is to set a session var after the record is created, but I would then need to unset it automatically so it doesn't keep showing. Any suggestions? Hi everyone, as the title stated, I would like to know how I could submit a form in one page(cart) and unset a session variable on other page.
Right now my form is setting a variable within the page back to 0, however I would like the form to unset the session variable from other page as well.
The issue with my code is that every time I attempt to clear out all items, my code can empty out the cart. But whenever I close and reopen the cart, the same content will show up again. So I need to unset the session variable.
Please let me know what should I do in order to solve the problem and I greatly appreciate your help.
My code is currently looking like this:
cart.php
if(!empty($_GET['aID']))
{
$aID = $_GET['aID'];
echo $aID;
if(isset($_POST['removeAll']))
{
$aID = "0";
}
$cartSQL = "SELECT * from article where aID in ($aID)";
echo "cart sql :$cartSQL";
$cartQuery = mysqli_query($dbc, $cartSQL) or die (mysqli_error($dbc));
while($row = mysqli_fetch_array($cartQuery, MYSQLI_BOTH))
{
$aTitle[] = $row[ 'name' ];
}
}
<form action = "" method = "POST">
<td style = "width = 200px"><input type="submit" value="Empty cart" name="removeAll"></td>
</form>
And this is the session variable from other page where I would like it to be unset upon submitting the form.
if(!empty($cartSubmit))
$_SESSION["cartSubmit"] = $cartSubmit;
else
$cart = $_SESSION["cartSubmit"];
<a href="javascript:popup('cart.php?aID=<?php if(empty($cartSubmit)) echo "$cart"; else echo "$cartSubmit";?>')">Cart</a>
I am using an if statement. If the user has a credit value of 1 or more it echos a variable thats a form. When the user submits the form, it takes a credit away, so the credit value is -1. I need the form to dissapear, because the form has a button that will execute a query that I dont want to execute. So, usually unset() fixes this, but its not in my case. Heres the code Code: [Select] $a='<strong></strong>'; if ($hintcredit<1) $a.='<font style="color: #cc0000;">You have already requested a hint! Once you guess the correct number, you will be able to get another hint. </font>'; else $form= "<form action='blablabla' method='post'>blablablabla</form>"; $a.=$form; $a.='<strong></strong>'; echo $a; if ($_POST['request'] == "Retrieve Hint") { unset($form); $form= '<b>One of the digits in your number is '.substr($num, -1).'</b>'; $newquery= "UPDATE userinfo SET hint_credits = '-1' WHERE username = '".$_SESSION['login_name']."'"; echo $form; mysql_query($newquery,$link); } In this case, the form is still being shown. I need the form completely removed after the form has been submitted. This is simple and idk why its not working for me!? I have 3 php's home.php createStep1.php createCheckPass.php createStep2.php home.php unsets some $_SESSION variables if they still exist from previous pages: Code: [Select] if(!empty($_SESSION['ame'])) { unset($_SESSION['ame']); } if(!empty($_SESSION['ject'])) { unset($_SESSION['ject']); } if(!empty($_SESSION['ports'])) { unset($_SESSION['ports']); } if(!empty($_SESSION['session_age_range'])) { unset($_SESSION['range']); } createCheckPass.php gets some posted information from createStep1.php, checks everything is ok and if so sets the above session variables createStep2.php gets the session data set by createCheckPass.php and then gets to work with the user inputting data into the db. The odd problem If createCheckPass.php finds any problems with the posted data it redirects the user back to createStep1.php with the sessions set, createStep1.php then displays the errors with the info set in the sessions to the user and everything works ok. If however the user sends the form from createStep1.php with no problems and the createCheckPass.php passes the user onto createStep2.php, something strange happens... The sessions set by the createCheckPass.php are only ever unset at the home.php, yet somehow createStep2.php loses the sessions and therefore doesn't run. What is even stranger is if i comment out the unsetting of the sessions from the home.php, everything works fine and none of the sessions are lost. Really really odd Summary: createStep2.php is reading the unset session lines of code from home.php when never asked to. Has anyone ever come across anything like this before? Good morning! I've spent hours on this to no avail. My understanding is that unset() only deletes the copy of the variable local to the current scope. But I am getting a very different result. I have the following structure and output. What am I doing wrong? <?php first_function(); second_function() { for ($count = 0; $count < $max; $count++) { $my_array = array[]; //initialize my array, local in this scope but can be called global in nested functions print_r($my_array ); //print 1: array should be always empty but is only in empty in FIRST loop. third_function(); //fills the array with numbers, see below, nested function declaring a global array print_r($my_array ); //print 3 of my_array, should be full of numbers from third_function global changes unset($my_array); //delete my array so I can start with new array in next loop print_r($my_array ); //print 4 of my_array, should be unknown variable print('End one loop'); } } third_function() { global $my_array; //declare my global variable //...fill my now global array with stuff... print_r($my_array ); //print 2: should be filled with numbers. And it is. } ?> My output amazingly looks something like this Array() Array(45,48,38...all my numbers...) Array() ERROR: Notice -- Undefined variable: my_array End one loop Array(45,48,38...all my SAME numbers again as if array was NOT unset...) ...... The first and second print lines make sense. But shouldn't the third line be the array filled with numbers generated in third_function? The fourth line error makes sense as the variable is unset. But WHAT did I unset? The next time around in the loop, the array contains the SAME numbers from the previous loop and my new numbers simply get appended to the end of the ever growing array. Why? This should not be that difficult but seems to be driving me crazy. Any help would be greatly appreciated. alexander I am using AJAX to access this file on my domain (weblyize.com), from my subdomain (ping.weblyize.com), and it keeps going into the if statement, logged is set on the domain, because I can see it when I go to a page that displays it. Anyone know why it is going into the if? If I go to the page directly, it works fine. header("Access-Control-Allow-Origin: *"); header("Access-Control-Allow-Methods: POST, GET"); header("Access-Control-Allow-Headers: NCZ"); header("Access-Control-Max-Age: 1728000"); session_set_cookie_params(0, "/", ".weblyize.com", false); session_start(); if(!isset($_SESSION['logged']) || !$_SESSION['logged']){ header("HTTP/1.0 400 Bad Request"); header("Status: 400 Bad Request"); exit; } Hello, I'm trying to test a simple login system without a db, just for testing purposes. I have created a php file that checks if the username and pass are valid and register a session. Code: [Select] <?php session_start(); define("ADMINUSER", "user"); define("ADMINPASSWORD", "pass"); $user = $_POST['user']; $pass = $_POST['pass']; if (($user==ADMINUSER) && ($pass==ADMINPASSWORD)) { $_SESSION['logged_in'] = true; header("Location: main.php"); } else { header("Location: auth.php?flag=wrong"); } ?> and include this in other files to check if the user is logged in: Code: [Select] <? session_start(); if ($_SESSION['logged_in'] != true) { header("Location: auth.php?flag=not"); exit; } ?> But this doesn't seem to work, as I closed the window, clear my cookies and shutdown my PC and when I try to open it again and it doesn't redirect me to the login page(auth.php). What am I doing wrong ? Any help is appreciated. I have two test files. First file: (test.php) <?php session_start(); function __autoload($class) { include "../libs/$class.php"; } $_SESSION = new session("ttocskcaj",84824526893564); echo "Welcome ".$_SESSION->getUsername(); echo '<p><a href="test2.php">Test 2</a></p>'; Second File (test2.php) <?php session_start(); function __autoload($class) { include "../libs/$class.php"; } print_r($_SESSION); echo "Welcome ".$_SESSION->getUsername(); echo '<p><a href="test.php">Test 1</a></p>'; But the second file just returns this; Code: [Select] Array ( ) Fatal error: Call to a member function getUsername() on a non-object in C:\xampp\htdocs\main\zend\TFFW\public\test2.php on line 4 Here's the session class https://github.com/ttocskcaj/The-Forum-Framework/blob/master/libs/session.php Is it even possible to save objects in a session? If so, what's going wrong? As the title says session, post and get are not working. This is what i use to initialize them. For get just switch session with get. Code: [Select] foreach ($row as $val) { $_SESSION[$rowcount] = $val; // echo "<td>$val</td>\n"; $rowcount=$rowcount+1; } when i was using session i would check to make sure that they were working with a couple of these lines in the same php document. Code: [Select] echo "Session row 1 = ".$_SESSION[0]."<br />"; echo "Session row 2 = ".$_SESSION[1]."<br />"; then on the next page where I was trying to receive the variables i was using this just to start off with and make sure i was getting the variables. Code: [Select] session_start(); if(!isset($_SESSION[1])){ echo "help1";}else{$var=$_SESSION[1]; } echo $_SESSION[1]; echo $var; if i switch to post and get i get the same results. if there is an easier way to pass variables between pages id love to hear them Hi everyone, I am trying to implement an OAuth system in PHP. I've got the code working but the very first time a fresh, new browser window is opened, the code doesn't work. If I refresh the page and try again, then it works. I have a few suspicions as to where the problem might be but other than that I am stumped. I have two classes: OAuthServer and OAuthClient. I create and store an object of the appropriate class in session variables. I know this is tricky but I am serializing and unserializing properly. To fetch responses from the Server, I am using curl. As curl uses a different session from the browser, I am doing a session_write_close before initializing curl and passing the appropriate parameters to curl. But my code needed to further write session variables even after session_write_close was called and to achieve this, I am calling session_start(), once again, after the curl code is finished. I found that this works but PHP was throwing warnings saying that the header info had already been sent or something like that, but I have suppressed such warnings. I suspect the error has something to do with this but I'm not sure. The part that doesn't work the very first time is that on the server-side, the session variable that is supposed to contain the OAuthServer object is NULL. But if I do a refresh of the page(flow: login_page->error_page), it works. Can anyone tell me why I am encountering the above error and if I am doing things correctly or not. Any help would be greatly appreciated. Thanks & Regards, GarbageGigo Hello, for some reason I am unable to get the following code to work: Code: [Select] <?php echo "<h1>Login</h1>"; if ($_SESSION['uid']) { echo " You are already logged in, if you wish to log out, please <a href=\"./logout.php\">click here</a>!\n"; } else { if (!$_POST['submit']) { echo "<table border=\"0\" cellspacing=\"3\" cellpadding=\"3\">\n"; echo "<form method=\"post\" action=\"./login.php\">\n"; echo "<tr><td>Username</td><td><input type=\"text\" name=\"username\"></td></tr>\n"; echo "<tr><td>Password</td><td><input type=\"password\" name=\"password\"></td></tr>\n"; echo "<tr><td colspan=\"2\" align=\"right\"><input type=\"submit\" name=\"submit\" value=\"Login\"></td></tr>\n"; echo "</form></table>\n"; }else { $user = addslashes(strip_tags(($_POST['username']))); $pass = addslashes(strip_tags($_POST['password'])); if($user && $pass){ $sql = "SELECT id FROM `users` WHERE `username`='".$user."'"; $res = mysql_query($sql) or die(mysql_error()); if(mysql_num_rows($res) > 0){ $sql2 = "SELECT id FROM `users` WHERE `username`='".$user."'

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 Hello guys. I'm in need of help. I want to know who to make a full working session. When a player logs in, the session starts. There will be a new button "My Page", he can go there at any time. When he logs off, that button disappears ( Session over ). I'm so bad at explaining stuff. Hope y'all really understood me. This piece of code is used to log the user in: Code: [Select] <?php session_start(); include("config.php"); if(isset($_SESSION["Username"])) { $user = $_SESSION["Username"]; $pass = md5($_SESSION["Password"]); } else { $user = $_POST["User"]; $pass = md5($_POST["Password"]); $_SESSION['Username'] = $user; $_SESSION['Password'] = $pass; $escuser = mysql_real_escape_string($user); $escpass = mysql_real_escape_string($pass); } $result = mysql_query("SELECT * FROM playerinfo WHERE user = '$escuser'"); $num_rows = mysql_num_rows($result); if($num_rows == 0) { echo('That username does not exist...'); echo '<a href="http://yu-ki-ko.com/fsns/""> Go back!</a>'; unset($_SESSION['Username']); unset($_SESSION['Password']); die; } $row = mysql_fetch_row($result); if($row[1] !== $escpass) { echo('Wrong Password!...'); echo '<a href="http://yu-ki-ko.com/fsns/""> Go Back!</a>'; unset($_SESSION['Username']); unset($_SESSION['Password']); die; } ?> Not sure if its working properly or not. I'm stuck at that part. hi guys. i am trying to set a variable to the session global variable. I've initialized the session with session_start(); at the very beginning of my website, and then i try finding if a session variable has been set like so if(isset($_SESSION['user'])) { print 'user is logged in'; } but this works in reverse. i have not set any session variables, but asking if it is set, results in an affirmative answer. so i am thinking this is because of register_globals. because i went to read about register_globals, and it says that if register_globals is turned off, i cannot use any other varibale except members of the session array. i dont know what that is yet, but a question befo in the php manual it says register_globals is deprecated, and it appears i need to enable it to set other variables as session variables besides it's associative array. if this is true, how to enable register_globals and allow other variables to be used as session variables? I have a link that sets a get variable that then performs a search based on that get variable. How after I the page has reloaded with the new search results how can I removed the $GET from the end of the url? Thanks for any help. Hi All I was wondering how important it is to unset() all your variables once used? Most of my code is object oriented so the functions discard any variables created within them. But do I have to unset() all the objects that I instantiate? Also how much will it improve on speed if I do so? Regards, Magnetica Hello, Am writing a script with lots of variables and its called by require() into the main file. But I probably have an interference in variable values because I get incorrect results. I have to unset all variables first before I enter the new script but there are lots of them. Is there a way I can unset all variables with a simple line of code or function? Thanks in advance |
