PHP - Php Cookie Problem
I'm having trouble setting a cookie in php. When a user logs in I send an ajax request to an file which contains this code to set the cookie
setcookie("userCookie", $_SESSION['username'], time()+60*60*24*30); However when I include the following code to check to see if the cookie has been set is says is hasn't if(isset($_COOKIE['userCookie'])) { echo("cookie set"); } else { echo("cookie not set"); } I check to see that my browser is accepting cookies and it definitely is so I'm not sure what causing the problem. Thanks for any help. Similar TutorialsHello, I am new to this forum and joined in hope I could get some help in relation to some PHP problems I have stumbled across within my work. I am currently working on an online store I am building from scratch. I have already built the basic system behind it and am now starting to implement a more user friendly design to it with JS validation, stylesheets and imaging layout. I have however come across a COOKIE problem with my login script. The purpose behind it is to only allow users into an area if they have logged in and declared cookies. I declare the cookies with 'setcookie()' then try and retrieve them with '$_COOKIE['firstname'];'. However since implementing my new design layout it has stopped being able to retrieve the cookies. Here is some of the script. I would greatly appreciate any help given ... Login.php Code: [Select] <?php //Validating input details and executing mysql query if ($username && $pass) { mysql_connect("$dhost","$dname","$dpass"); //Connection to mysql server @mysql_select_db("$dbase") or die ("Unable To Select Database!"); //Connection to stated database $query = "SELECT firstname, lastname, username FROM userdata WHERE password=SHA('$pass')"; //Retrieves firstname and lastname for username and password combination $result = @mysql_query ($query); $row = mysql_fetch_array ($result,MYSQL_NUM); //Return a record, if applicable if ($row) { setcookie('firstname', $row[0], time()+3600); setcookie('lastname', $row[1], time()+3600); setcookie('username', $row[2], time()+3600); //Set the cookies echo "<p class='Body-error-P'><span class='Body-text-T'>Login successful. If you are not redirected in 15 seconds click <A HREF='./index.php'>here</A></span></p>"; print "<meta HTTP-EQUIV='REFRESH' content='5 url=./index.php'>"; } else { //no record matched the query echo "<p class='Body-error-P'><span class='Body-text-T'>The username and password you entered are not valid.</span></p>"; } mysql_close(); //close database connection } } Index.php Code: [Select] <?php include_once ("config.php"); if(isset($_COOKIE['firstname'])) //if not cookie present, redirect the user { echo "<p class='Body-text-P'><span class='Body-text2-T'>You are now logged in, <b>".$_COOKIE['firstname'].' '.$_COOKIE['firstname']."</b></span</p>"; } else { echo '<p class="Body-text-P"><span class="Body-text-T">You are not logged in at this current time.

Hello A few days back I searched for a (very) easy php login script, basicly just to show hidden content that's not for everyone. This is the script I found (and it works): <?php $username = "Username"; $password = "Password"; $randomword = "one"; if (isset($_COOKIE['MyLoginPage'])) { if ($_COOKIE['MyLoginPage'] == md5($password.$randomword)) { ?> <?php include 'projecten_.php'; $name = "0"; ?> <?php exit; } else { echo "<p>Bad cookie. Clear please clear them out and try to login again.</p>"; exit; } } if (isset($_GET['p']) && $_GET['p'] == "login") { if ($_POST['name'] != $username) { echo "<p>Sorry, that username does not match. Use your browser back button to go back and try again.</p>"; exit; } else if ($_POST['pass'] != $password) { echo "<p>Sorry, that password does not match. Use your browser back button to go back and try again.</p>"; exit; } else if ($_POST['name'] == $username && $_POST['pass'] == $password) { setcookie('MyLoginPage', md5($_POST['pass'].$randomword)); header("Location: $_SERVER[PHP_SELF]"); } else { echo "<p>Sorry, you could not be logged in at this time. Refresh the page and try again.</p>"; } } ?> <body style="background:url(images/repeat.gif) repeat-x #0a0a09; height:106px; margin:0px; padding:0px; text-align: center;"> <div style="margin-left: auto; margin-right: auto; position: relative; top: 120px; width: 250px; text-align: left; line-height: 28px;"> <img src="images/zenze.png" alt="Zenze" style="position: absolute; top: -100px; left: -375px;" /> <h5 style=" font-weight: none; font-size: 18px; font-family: verdana; margin: 0px; margin-bottom: 20px; color: #96ff00">Login</h5> <form action="<?php echo $_SERVER['PHP_SELF']; ?>?p=login" method="post"> <label><input type="text" name="name" id="name" /><span style="color: #999999; font-size: 12px; font-family:verdana"> Name</span></label><br /> <label><input type="password" name="pass" id="pass" /><span style="color: #999999; font-size: 12px; font-family:verdana"> Password</span></label><br /> <input type="submit" id="submit" value="Login" style="margin-top: 10px;" /></form> </div> </body> The only problem is, there is no log out fuction. I see this script works with cookies and I gave it a try, and I ended up with nothing but errors. Does anyone one has an idea to how a logout script would look like for this script? Thanks in advance, Crow 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 Hello community, I am trying to create a login script, but in the HTTP Header it only sends the last cookie set. I first tried this code: $expire=time()+60*60*24; setcookie("gcg_user",$userid,$expire); setcookie("gcg_name",$username,$expire); setcookie("gcg_pass",$password,$expire); But it only set the gcg_pass cookie. Someone else suggested me to use header(): $expire=date(DATE_RFC822,time()+60*60*24); header('Set-Cookie: gcg_user="'.$userid.'"; expires='.$expire.';'); header('Set-Cookie: gcg_name="'.$username.'"; expires='.$expire.';',false); header('Set-Cookie: gcg_pass="'.$password.'"; expires='.$expire.';',false); But again it only sets the last cookie. The first code has been working fine on another server. Do I have to adjust anything in php.ini? Running XAMPP Lite: Quote ###### Apache Friends XAMPP Lite (Basis Package) version 1.7.3 ###### + Apache 2.2.14 (IPV6 enabled) ... + PHP 5.3.1 (PEAR) ... Any help on that? Thanks in Advance! Hey guys, I have developed an script which opens or fetches a page using curl, now the problem is the url i am trying to fetch follows lot of redirects(say 302) and in between it stores several cookies also which i don't know or guess. So i was just thinking, is there any way so that i can automatically store the cookies in a particular file which server wants to store, and let it sent in request as per the asking of a request in request header? I hope you would have got what i mean to say here, for example suppose i want to open http://www.example.com and now that above url faces lot of redirects probably 5-6 and then ends up on http://www.test.com now in between it stores some cookies in clients computer and then it fetches them also. Since i don't know which cookie it gonna store, I must put this responsibility to PHP itself to store and send the requested cookies in request headers. Also i want to send the referrer also in request header, and it must be the last page that or request sent to the server, no matter whether it's in betwen redirects or to the final page. In short i mean to create the complete emulation of browser for this URL. Hi,
I'd stumbled upon a problem around doing curl on an asp website which use cookie.
I use username n session id to determine the cookie file, on a case when a second browser open up it should have different session id, hence it may create new cookies instead of using the active previously-made cookie file, please do correct me if I'm wrong.
So question is....how to detect a user is logged or not in such situation ?
Or perhaps how is the proper way to determine a cookie file in such situation ?
Thanks in advance,
Alright so I have coded a login system, and logging in works. But I just noticed that logging out did not work. I tried making a test cookie at the very top of my document, and it worked. I couldn't find out why, because there's really nothing in between than can be causing it. I tried moving the code down line by line until it stopped working, it happened after a block of html code. Makes no sense to me at all. Here's the working code, it sets the cookie and returns "Set": Here's the same code a few lines down, cookie is not being set and returns "Not set": Why? XD I tried removing that entire div-block but then the code would just stop working a bit further down in my document. It's a challenge to you, phpfreaks I have a very odd cookie problem that's hard to explain so please bare with me... The first piece of code found below is the login process, where the login is checked and the cookie is created or not, the second piece of code below is a library which is called to display the login menu and get the connection to the database. The problem I'm having is I cant put these 2 files in the same folder. The cookie gets created if i put the process login into a directory and the library into a sub directory called inc ... then i "include("inc/library.php");" in the login process. I then point the form for the login to http://www.alcaeos.com/blog/loginProcess.php... If I do these 2 things then the cookie is created but if I place both files in the inc folder (The code below is the example of when both files are IN the inc folder) then the cookie does not get created. the login system still works and tells the user if they successfully logged in or not, it just wont create the cookie... It's an odd problem I think. Has anybody got any ideas... Thanks Code: [Select] <?php include("library.php"); connectToDatabase(); $username = $_GET['username']; $password = $_GET['password']; $sql = "SELECT * FROM theUsers WHERE user = '$username' AND pass = '$password';"; $result = mysql_query($sql) or die(mysql_error()); if ($obj = mysql_fetch_object($result)) { $expire=time()+60*60*24*30; setcookie("shopusername",$username,$expire); echo "<A HREF='http://www.alcaeos.com/blog/test.php'>You are logged in</A>"; } else { loginScreen(); echo "You are NOT Logged In"; } $db->close(); ?> Code: [Select] <?php function loginScreen() { $output = <<<LOGIN <FORM method ="GET" action="http://www.alcaeos.com/blog/loginProcess.php"> <table> <tr> <td>Username: </td> <td><INPUT TYPE = "text" NAME = "username"></td> </tr> <tr> <td>Password: </td> <td><INPUT TYPE = "password" NAME = "password"></td> </tr> </table> <INPUT TYPE="submit"> </FORM> LOGIN; echo $output; } function connectToDatabase() { $dbhost = 'mysql*******'; $dbuser = 'kem*******'; $dbpass = 'ya****'; $conn = mysql_connect($dbhost, $dbuser, $dbpass) or die('Error connecting to mysql'); $dbname = 'ke********'; mysql_select_db($dbname); } hello all, I have a client that wants to protect their web page with a password protected landing page. Once the password is entered the user is directed to a "disclaimer" page that they have to agree to first before going into the site. I have put both the landing page and the disclaimer page in my root directory and then the site I put in a sub directory /cms/ in the main site index.php I check for the post password and then set a $_COOKIE for the user that will expire in 1 month <?php // this goes on the very top of the index.php file in the template you are using //check if user has entered password and needs cookie set if(isset($_POST['fpass']) && !isset($_COOKIE['fpass'])) setcookielive('fpass', $_POST['fpass'], strtotime( '+1 month' )); function setcookielive($name, $value='', $expire=0, $path='', $domain='', $secure=false, $httponly=false) { //set a cookie as usual, but ALSO add it to $_COOKIE so the current page load has access $_COOKIE[$name] = $value; return setcookie($name,$value,$expire,$path,$domain,$secure,$httponly); } The next thing I do is check if a user is trying to access the main site with having the COOKIE - if so I redirect the user to the landing page //check if user has not entered password if (!isset($_COOKIE['fpass']) || $_COOKIE['fpass'] == "") header('location: http://www.mypage.com'); This works fine up to this point. Now my problem is that I also need to check if a user has the month long cookie set but is trying to access the main page without viewing the disclaimer page first. I thought this would work: //check if the user has a cookie set but is on a new session if (isset($_COOKIE['fpass']) && !isset($_SESSION['fpass'])) header('location: http://www.mypage.com/disclaimer.php'); But this only throws the user into a loop of "disclaimer" -> "landing page" -> "disclaimer" etc. They can never get into the main site. How do I check for the cookie and whether the user has visited the disclaimer page - but then allow the user to continue once they go to the disclaimer page? NB: the $_SESSION is not set until the main site. I'm writing a cookie using VB in an ASPX file: Code: [Select] username = "myname" If Request.Cookies("username") Is Nothing Then Response.Cookies.Set(New HttpCookie("username", username)) Response.Write("newcookie <br />") Else Response.Cookies.Set(Request.Cookies("username")) Response.Write("not nothing <br />") End If Response.Cookies("username").Expires = DateTime.Now.AddYears(1) and I can read it in PHP: Code: [Select] if (isset($_COOKIE['username'])) { $username = $_COOKIE['username']; } But when I kill it with PHP ... Code: [Select] if (isset($_COOKIE['username'])) { setcookie ("username", NULL, time()-3600*24*300 ); //300 days unset($_COOKIE["username"]); } ... the VB in the ASPX file still sees it and thinks it's an empty string, since it returns: "not nothing" It would seem that the cookie is still alive somewhere, no? And how do I kill it completely, so that the VB writes a new cookie with the same name? Hello, I am having trouble setting a cookie with a future expiration. I am using PHP Version 5.1.6. Here is my code: $expire = time() + 60*60*24*30; // 30 days setcookie("TestCookie",$value, $expire); The cookie gets set, however, the cookie is not persistent and expires when I close my browser. This should not be the case but should expire in 30 days. The time() is correct on the server. Here is the raw http headers: Status: HTTP/1.1 200 OK Date: Sat, 26 Mar 2011 15:12:27 GMT Server: Apache/2.2.3 (CentOS) X-Powered-By: PHP/5.1.6 Set-Cookie: TestCookie=my+cookie+value; expires=Mon, 25-Apr-2011 15:12:27 GMT Content-Length: 126 Connection: close Content-Type: text/html; charset=UTF-8 However, when I open Firefox or Chrome they both say that the cookie will expire when I close the browser. I know that my browser is accepting cookies properly because I see other cookies from other websites in the cookie list that expire with future dates. I've tried setting a cookie in the future with javascript and it works fine, like the following: $jsExpire = date("D, j M Y H:i:s e", $expire); echo " <script> <!--// document.cookie = 'jscookie=testcookie; expires=$jsExpire; path=/' //--></script> "; However, when still trying to set the cookie (before headers are sent which is how php operates), php fails to set the cookie properly. Is there any kind of setting in php ini that could effect cookie expiration dates? Obviously it's not a browser problem since I can set cookies correctly with javascript but not php. I even tried sending cookie with header() like this and it doesn't set in the futu header("Set-Cookie: TestCookie=my+cookie+value; expires=Mon, 25-Apr-2011 17:26:45 GMT; path=/; domain=.mydomain.com"); Any help appreciated. This works fine on localhost, but the same code just won't update my live website cookie. Here's the code: index.php Code: [Select] $lg->updateCookies($username, $hashSalt[0]); updateCookies function: Code: [Select] $site = '.ciadacapa.com.br'; // --------------------------------------------------- // Updates the cookies // --------------------------------------------------- function updateCookies($username, $hash){ setcookie('ciadacapaUser', '', time()-3600, '/', $this->site); setcookie('ciadacapaHash', '', time()-3600, '/', $this->site); setcookie('ciadacapaUser', $username, time()+3600*24*7, '/', $this->site); setcookie('ciadacapaHash', $hash, time()+3600*24*7, '/', $this->site); return true; } Although the class is receiving the correct values, the cookie just retains the old value it had and never updates. Any ideas on this? Thanks in advance! Ok I have my login form and previously I was using $_SESSION untill I learned this removes data when browser is closed. Someone said to me to use cookies but I have no clue where to begin on setting a cookie or reading information from it. Can anyone point me to a tutorial on cookies? Hi all, I'm struggling with a program I'm trying to write with cookies, so any help would be very much appreciated!! What I'm wanting to do is when someone visits my site, I want to display content until the end of the day, and once the days up it disappears forever/until the cookies are deleted. Could someone help me with this? Thanks lots in advance, Jake Hey PHPFreaks! I have a problem with my login script, because when i login it sets a cookie and it all works. But when i got redirected and refresh the page, my script turns an error which says i'm not logged in? how come? This is what finds the cookie and redirects me Code: [Select] if(!isset($_SESSION['auth']) && !isset($_COOKIE['authcookie'])) { $_SESSION['ERROR'] = 7; header('location: index.php?login'); } 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 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"); 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; |
