PHP - Setting, Then Destroying Cookie
Here is my code that sets the cookie for a year:
//set a cookie for a year setcookie('user', $username, time()+31536000); My code that unsets it: <?php unset($_COOKIE['user']); header("LOCATION:index.php"); ?> Why doesn't it log the user out? Similar TutorialsHi, I'm trying to set cookie but all in vain. I've already posted my php code in my last post. "COOKIE PROBLEM". I think there is nothing wrong with code. may be i need to enable to load some library or something in xampp. Is there anyone who knows what setting do i need to do for enable cookies and in which file? Please help Hello, My latest issue is with a login page I am trying to set a cookie for. I have deduced that it it pulling my info out of my database correctly. It does not give any errors for username or password when they are entered correctly but when I get to the end of the script where I would like to set a cookie and redirect to a new page it just stays on the same page and appears as if it is loading but nothing happens. After I stop the browser and attempt to reload the page it gives me an error saying the page cannot be displayed. Do I need to specify anything before I can have the following code work or is it that it is clashing somewhere else along the way? Code: [Select] <?php else { // if login good set cookie $_POST['username'] = stripslashes($_POST['username']); $hour = time() + 3600; setcookie(ID_my_site, $_POST['username'], $hour); setcookie(Key_my_site, $_POST['pass'], $hour); //then redirect them to the members area header("Location: http://example.com/"); die(); } ?> If I remove this code and simply leave the redirect as shown above, it works. But that defeats the purpose of the script as on the redirected page there has to be a cookie set to display it. Any help would be appreciated I have a web application in which there are two php files index.php and include.php . include.php is loaded to a DIV tag inside index.php on click of button using Jquery . Both these php files share a common varible through cookie which is used to keep track of the data retrived by include.php . This variable will be updated each time include.php retrives data . These php code work fine Mozilla and chrome but not in IE . When i checked the cookie value it is same through out without setting . Please help . Thanks in advance , Rahul Hi, I'm pretty new to php, and to this site as well, so please bear with me... I have a table in my database which has "user_id" as its primary key, and i want to set the values under this as a cookie. I've put in bold the main things that are affecting it (I think). As is, the mysite_userid cookie does not set properly, and I get an error like this "Header may not contain more than a single header, new line detected...." Any help would be really appreciated!! <?php include("connect.php"); $match = "select user_id from $table where username = '".$_POST['username']."' and password = '".$_POST['password']."';"; $qry = mysql_query($match) or die ("Could not match data because ".mysql_error()); $num_rows = mysql_num_rows($qry); if ($num_rows <= 0) { echo "Sorry, there is no username ".$_POST['username']." with the specified password. "; echo "Try again"; exit; } $remember = strip_tags($_POST['remember']); if ($remember) { setcookie("loggedin", "TRUE", time()+3600*24); setcookie("mysite_username", "".$_POST['username'].""); header("Location: members.php"); } else { setcookie("loggedin", "TRUE"); setcookie("mysite_username", "".$_POST['username'].""); setcookie("mysite_userid", $qry); $site_username = $HTTP_COOKIE_VARS["mysite_username"]; $site_userid = $HTTP_COOKIE_VARS["mysite_userid"]; header("Location: members.php?user=$site_userid"); } ?> hi today i was checking a site as i m learning more about curl. i see i was not able to get image with curl. they have stopped hotlinking and was not finiding anyway to show me image on my localhost so making this thread for any pro help. here is my code: $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, "http://www.pixhost.org/show/2019/5530476_banner.png"); curl_setopt($ch, CURLOPT_USERAGENT, "Opera/9.80 (Windows NT 5.1; U; en) Presto/2.5.24 Version/10.54"); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($ch, CURLOPT_COOKIE, 'pixhostads=1'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $result = curl_exec ($ch); echo $result ; if i run that script it will show me that page but it says pictures is hotlinked and cant display, so i tried to see cookie but i m not sure if i am doing it right. on that url u must need to click "Click to continue" before u can see image. Please can someone help why its not showing me the correct image and any way to pass it? thanks Hi girls and boys I am trying to set a variable if a session OR a cookie has been set, but am unsure on how to write the statement... if (isset($_SESSION['name'])||isset($_COOKIE['name'])) {$variable = $_SESSION['name']||$_COOKIE['name'];} Obviously not working there, but just need a pointer here. any help is appreciated... Working making an jquery ajax/php chat system It thought to myself wouldnt it be cool to have commands for admins? Any way I was thinking how the kick command would work. If I keep a list of all the session ID's in a table how can I get PHP to kill a session based on a certain session ID? Say for example some users session ID was 3evirkjonfg5dr4s5b783nvvf0 how can I use that to instantly kill a session so the user is logged out? Hi, probably a simple solution to this which I am overlooking, doing my first foray into using cookies. So far all is well, but how do I make a cookie valid for both www.mysite.com and mysite.com Code: [Select] if(isset($_POST['remember'][1])) { $session_id = md5($_SESSION['username'] . $_SESSION['last_login']); setcookie("session_id", $session_id, time()+60*60*24*30, "/"); } Thanks, TS Hi, I am facing problems in destroying the session variables in my logout file .I have used session_id() in my php files for ex $sid = session_id().Now when I click on logout I naviagte to my index file but the session variable $sid still remain.I have chkd it.I have kept session_start() function in a file and I am including that file in every php by require_once function.The file is palced in Includes folder..is it causing the problem?? please help me out Also can I use session_start() more than once in a single php file?

were am i going wrong???
In the following code, Code: [Select] // Register Globals if (ini_get('register_globals')) { ini_set('session.use_cookies', 'On'); ini_set('session.use_trans_sid', 'Off'); session_set_cookie_params(0, '/'); session_start(); $globals = array($_REQUEST, $_SESSION, $_SERVER, $_FILES); foreach ($globals as $global) { foreach(array_keys($global) as $key) { unset($$key); } } } the above destroys all globals if register_globals is on, as I understand it. However, if it does destroy all globals, can a web form continue to work? How do you allow form fields and other stuff to be used in a script even if you kill all the globals up front? Many thanks I have part of my script that I have used many times in many diffrent applications that works just fine. But in this use it refuses to set the cookie or do anything besides the redirect for that matter. // if login is ok then we add a cookie $ip = $_SERVER['REMOTE_ADDR']; $datem = date("j F Y, g:i a"); mysql_query("UPDATE YBK_Login SET date = '$datem' AND ip = '$ip' WHERE ID = '{{$info['ID']}'")or die(mysql_error()); $_POST['username'] = stripslashes($_POST['username']); $hour = time() + 3600; setcookie('ID_WatsonN', $_POST['username'], 0); setcookie('Key_WatsonN', $_POST['pass'], 0); setcookie('UID_WatsonN', $info['ID'], 0); setcookie('LOGIN', $info['ID'], time()+3); //then redirect them to the members area Header("Location: dashboard.php"); Hey PHPFreaks! I have a problem with my login script, because when i login it sets a cookie and it all works. But when i got redirected and refresh the page, my script turns an error which says i'm not logged in? how come? This is what finds the cookie and redirects me Code: [Select] if(!isset($_SESSION['auth']) && !isset($_COOKIE['authcookie'])) { $_SESSION['ERROR'] = 7; header('location: index.php?login'); } Ok I have my login form and previously I was using $_SESSION untill I learned this removes data when browser is closed. Someone said to me to use cookies but I have no clue where to begin on setting a cookie or reading information from it. Can anyone point me to a tutorial on cookies? i want to store the nickname of the user as a cookie.. somthing like set cookie name=nickname,value=smarty,expires after 1 week i know cookies are stored against domain names. what happens when another person logs in the same computer, with different login, and his nickname is diff how does the cookie get handled, and how does the right nickname flash against the right persons login id... Hi all, I'm struggling with a program I'm trying to write with cookies, so any help would be very much appreciated!! What I'm wanting to do is when someone visits my site, I want to display content until the end of the day, and once the days up it disappears forever/until the cookies are deleted. Could someone help me with this? Thanks lots in advance, Jake I have a question about cookies I want the cookie to work on all the paths / folders / directorys located in a root path. So say like.. http://www.site.com/members/login.php is the folder which sets the cookie, then this cookie will also work on like.. http://www.site.com/bla/boo/works.php I'm trying to do: setcookie(Data1, 'valueofthecookie', '/', '.site.com', 1); But its not working... Hi, I was trying to use setcookie on my website but when I try to use, it wasn't setting anything and then I tried to make sure if it's setting something, I added Code: [Select] echo $_COOKIE;But it shows Array (just the word) instead of tblogvalue. This is the code I'm using; Code: [Select] $Month = 2592000 + time(); setcookie(tblog, tblogvalue, $Month); echo $_COOKIE; how can i set cookie like a*dm*n@**t*r*c**.*c** ?? Code: [Select] $cookkiee = $islem_1['mail'] ; $sayisi = strlen($cookkiee)-1 ; $cok = $islem_1['mail'] ; for($i=0;$i<=$sayisi;$i++) { $sifr = rand(0,2); if($sifr ==0) { $cok[$i]= '*'; } $dizik = $cok[$i]; setrawcookie("kayip",$dizik,time()+(60*30),"/"); $_COOKIE['kayip'] = $dizik; echo $dizi // etc . a*dm*n@**t*r*c**.*c** } echo $_COOKIE['kayip']; // etc. just one char being like random a if a user clicks ?hide=1 or ?hide=2 it does Code: [Select] if (isset($_GET['hide'])){ $id = intval($_GET['hide']); setcookie('hide', ''.$id.'',time()+32000000); header('Location: index.php'); exit; } How do I make it so if they click ?hide=1 it ad's 1, but what if they do ?hide=2 also? it would need to be 1,2 not just 2. |
