PHP - Cookie Not Working
I am trying to pass a variable as a cookie from one page to another, but can't seem to get it working.
The first page has a form with a submit button. The forms action goes to a second page called updated.php. In the updated.php page I have the following code (with the cookie right at the top before anything else): <?php setcookie("get_orderID", $get_orderID, time()+5); ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> etc... Later in this page I have the code to send the original form data to an sql database and then retireve an auto increment value back from the database as follows: <?php if($edit_orderID == 0) { $submit_order_sql = "insert into my_orders (date, name, clientID) values ( \"$date\", \"$name\", \"$clientID\" )"; $submit_order_rs = mysql_query( $submit_order_sql, $conn ); $get_order_sql="select orderID from my_orders where job_no = $job_no"; $get_order_rs = mysql_query( $get_order_sql,$conn ); $get_order_row = mysql_fetch_array( $get_order_rs ); $get_orderID = $get_order_row["orderID"]; ?> Finally I need to send the variable I have found back to the form page (using a cookie). But it seems that as the variable is being created at the bottom of the page, the cookie at the top is not seeing the variable. Can anyone help please?? Thanks. Similar TutorialsHello, I'm having an issue with using a php variable (of the current page url) as a cookies name. Here's an example of what I'm trying to do: Code: [Select] $directory = "/main/index.php?id=7"; $cName = "path_".$directory; if(isset($_COOKIE[$cName])){ echo "Do something NOW!!!"; setcookie($cName, '1', mktime(23,59,59)); } echoing the isset check doesn't return anything, no 0, no 1. I can print_r $_COOKIE; and it shows the cookie exists, I just can't check if it exists with what I'm doing here. From what I've learned is that the cookie name is something like: "testing" it works just fine, but if it's that $cName variable it doesn't work. Any ideas? Hello,
I have a song streaming website, and i want to set a cookie inside a player popup to avoid that users increment the number of times that an album was played every time they access it.
I want the cookie to last at least 6h, but every time i test the code with 1,2 or 5 minutes it never ends in the time that i specify. For example i want it to last 3min and it may take 5 or 2min to end. Cant figure out why, because i used the same cookie code in a none popup window and it worked.
// player.php (POPUP)
<?php
session_start();
include("include/player-functions.php");
uniqueAlbumListens($db,$_GET['id']);
(...)
?>
//player_functions.php
<?php
(...)
function uniqueAlbumListens($db,$id){
if(!isset($_COOKIE["ml".$id])){
updateListens($db,$id);
}
setcookie("ml".$id, "listens", time()+60*2); // 2minutes -> 60*2 ? || 6h -> 60*60*6 ?
}
(...)
?>
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 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. 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 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; 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... 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"); Ok I have my login form and previously I was using $_SESSION untill I learned this removes data when browser is closed. Someone said to me to use cookies but I have no clue where to begin on setting a cookie or reading information from it. Can anyone point me to a tutorial on cookies? Hey PHPFreaks! I have a problem with my login script, because when i login it sets a cookie and it all works. But when i got redirected and refresh the page, my script turns an error which says i'm not logged in? how come? This is what finds the cookie and redirects me Code: [Select] if(!isset($_SESSION['auth']) && !isset($_COOKIE['authcookie'])) { $_SESSION['ERROR'] = 7; header('location: index.php?login'); } 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... 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 Can you send a cookie through ajax? Will it still be read by the browser? How can I use a cookie to pull data from my db. Right now I have it set up to pull data from a session variable, but I need it to be able to display data from both since I am implementing a remember me checkbox on my login. Current Code: $q = mysql_query("SELECT `firstname`, `lastname`, `firstname`, `lastname`, `email`, `entrepreneur`, `investor`, `companyname`, `companywebsite`, `founder`, `phone`, `address`, `city`, `state`, `zipcode`, `country`, `development`, `capitalamount`, `companydo`, `founderbuilt`, `understand`, `competition`, `money`, `demo`, `incorporation`, `companynameinv`, `phoneinv`, `addressinv`, `cityinv`, `stateinv`, `zipcodeinv`, `countryinv`, `angel`, `vc`, `capital` FROM `users` WHERE username= '" . $_SESSION['username'] . "'"); $r = mysql_fetch_assoc($q); if (!isset ($_GET['u'])&&($_SESSION['username'])||($_COOKIE['username'])) { echo "blahblah" Hello, I am new to this forum and joined in hope I could get some help in relation to some PHP problems I have stumbled across within my work. I am currently working on an online store I am building from scratch. I have already built the basic system behind it and am now starting to implement a more user friendly design to it with JS validation, stylesheets and imaging layout. I have however come across a COOKIE problem with my login script. The purpose behind it is to only allow users into an area if they have logged in and declared cookies. I declare the cookies with 'setcookie()' then try and retrieve them with '$_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. Please login or register.</span</p>'; } ?> Let me know if you need anymore coding... Hi All, I have a secure website which always checks the cookies is not expired and the session id is set. When someone doesn't browse for the period of the cookie it will expire however the session id stays valid until he logout. A lot of people don't logout so the pages will still be accessable for them or others who use their pc. Is there a way to destroy the session id when the cookies expires? Marco This topic has been moved to Miscellaneous. http://www.phpfreaks.com/forums/index.php?topic=346675.0 Hey guys I'm pretty new to both PHP and Javascript. I think my problem is a PHP one, not a Javascript one. But it involves both. I'm trying to delete a cookie by clicking a link. I call the javascript function like so: if (isset($_COOKIE["active"])) { echo "<a href='addpost.php'>Add Post</a> <a href onClick='eraseCookie()'>Log Out</a>"; } And the function looks like this: Code: [Select] function eraseCookie() { <?php setcookie(active, 0, time()-3600); echo "It works"; ?> } The function doesn't delete the cookie and doesn't echo "It works". Like I said this could be a Javascript error, not a PHP one, but I have to start somewhere. Can someone tell me what I'm doing wrong? I was told that my login page could easily be manipulated to set themselves as my username (Mod Justin), giving them powers. How can I further secure my website's use of cookies? Quote I just visited your site as you - Mod Justin, simply by setting a 'user' cookie for your domain with your username in it. Your login code is NOT effective at stopping anyone or any bot script from impersonating any of the users, even impersonating you. My login code: http://pastebin.com/cBLybGKq Any possible solution to this? <? $name = $_GET['name']; $game2 = "2": setcookie('game_".$name."',$game2, time()+3600); ?> would this work? if not how can it be done? cheers matt |
