PHP - Cookie Question
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? Similar TutorialsI have a quick Question guys about a code i am using! Basicly i have a from which call the login.php which should create a cookie and display Welcome $_cookie['username'] but it doesnt seem to work? If anyone here spots my error please call me on in. Code: [Select] <form name="login" method="post" action="scripts/login.php"> Username: <input type="text" name="username"> <br> Password: <input type="password" name="password"> <br> Remember Me: <input type="checkbox" name="rememberme" value="1"> <br> <input type="submit" name="submit" value="Login!"> </form> Login.php Code: [Select] <?php /* These are our valid username and passwords */ $user = 'guest'; $pass = 'guest'; if (isset($_POST['username']) && isset($_POST['password'])) { if (($_POST['username'] == $user) && ($_POST['password'] == $pass)) { if (isset($_POST['rememberme'])) { /* Set cookie to last 1 year */ setcookie('username', $_POST['username'], time()+60*60*24*365, '/account', 'c:/wamp/www/notemapper'); setcookie('password', md5($_POST['password']), time()+60*60*24*365, '/account', 'c:/wamp/www/notemapper'); } else { /* Cookie expires when browser closes */ setcookie('username', $_POST['username'], false, '/account', 'c:/wamp/www/notemapper'); setcookie('password', md5($_POST['password']), false, '/account', 'c:/wamp/www/notemapper'); } header('Location: ../index.php'); } else { echo 'Username/Password Invalid'; } } else { echo 'You must supply a username and password.'; } ?> here is how i am testing to see if my cookies are being set which they arnt! Code: [Select] <?php if (isset($_COOKIE['username'])) { echo $_COOKIE['username']; } else { include("widgets/login.html"); } //This is just to see if the cookie is set? echo $_COOKIE['username']; ?> 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, 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... 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 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', $info['ID'], time()+3); //then redirect them to the members area Header("Location: dashboard.php"); if a user clicks ?hide=1 or ?hide=2 it does Code: [Select] if (isset($_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. 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 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 $_COOKIE['kayip']; // etc. just one char being like random a Hey PHPFreaks! I have a problem with my login script, because when i login it sets a cookie and it all works. But when i got redirected and refresh the page, my script turns an error which says i'm not logged in? how come? This is what finds the cookie and redirects me Code: [Select] if(!isset($_SESSION['auth']) && !isset($_COOKIE['authcookie'])) { $_SESSION['ERROR'] = 7; header('location: index.php?login'); } How to get the cookie value,when we login for a website,also how to access the site by using the cookie values? 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 Hi All,
I seem to be getting in a right mess with this, so hope someone can help.
I'm simply trying to set a cookie called 'defaultLanguage'.
It will initially be set to English and when someone completes a form, the form value is then passed and used in the cookie.
here's my code:
$cookie_name = 'defaultLanguage';
$cookie_value = $_GET["language"];
if ($cookie_value == ''){
$cookie_value = 'English';
}else{
$cookie_value = $_GET["language"];
}
setcookie($cookie_name, $cookie_value, time() + (86400 * 30), '/'); // 86400 = 1 day
I then use this to test/check:
$cookie_name = 'defaultLanguage';
if(!isset($_COOKIE[$cookie_name])) {
print 'Cookie with name "' . $cookie_name . '" does not exist...';
} else {
print 'Cookie with name "' . $cookie_name . '" value is: ' . $_COOKIE[$cookie_name];
}
If I clear my browser cookies, this is what happens:
On initial page load it says: Cookie with name "defaultLanguage" does not exist...
If I reload the page or move to another, it says: Cookie with name "defaultLanguage" value is: English
If I then complete my form, ?language=French is added to the URL, however, it still says: Cookie with name "defaultLanguage" value is: English
I think I' missing something obvious but can't see for looking!!
Any help is much appreciated
Hi All,
I hope someone can help!
I've got some code that passes an array of values via an ajax call. This works fine and I can see my values in the specified div:
$("#container").html(data);
What I'd like to do, is get that info and pass it to a cookie. However, I'm struggling a tad. I currently have this:
var set_me = html(data);
$.cookie('choice',set_me, {expires: 7, path: '/'});
alert( $.cookie("choice") );
But sadly it's not working. I think it's something simple but this is new to me some need some help please
Thanks
<? $name = $_GET['name']; $game2 = "2": setcookie('game_".$name."',$game2, time()+3600); ?> would this work? if not how can it be done? cheers matt I am working on a website that depends on a complex cookie being set. In an effort to fix problems before they become big problems, I want to monitor that the cookie is getting set correctly with a cron job. I can setup the cron job just fine, but I can't figure out how to get the value of the cookie. By visiting the main site the cookie is set automatically, and I've also made a special script on that server that only gets me that cookie value and spits it out. I am trying to use cURL to call the main page, and then right after that, call the get-cookie.php page which should then have cookie data to display. Here is how I am trying to do it now: <?php $c = curl_init(); // making the initial call to the real website curl_setopt($c, CURLOPT_URL, 'http://domain.com'); curl_setopt($c, CURLOPT_HEADER, false); curl_exec($c); curl_close($c); $c = curl_init(); // now making a call to the script that spits out the cookie curl_setopt($c, CURLOPT_RETURNTRANSFER, true); curl_setopt($c, CURLOPT_URL, 'http://domain.com/get-cookie.php'); curl_setopt($c, CURLOPT_HEADER, false); $output = curl_exec($c); curl_close($c); echo 'output: ' . $output . "\n\n"; ?> I've tried a few different things here, but so far no luck. Anyone have any ideas on how I can make this work? Thanks so much! I'm not really sure if this is a cookie problem but that's all I could think of. I have a web site that users have to log into. I have seen that when I log out of my account and log into my test account my main user name will still show on the welcome page unless I let the computer sit for a bit or if I clear recent history. This happens in all the main browsers. I have also started having a problem where if I update something in my database it shows up in MySQL right away but can take a while to show up on the web page unless i clear the history. Not sure what code to post to give you an idea so if you want to see something let me know and I will put it up. Thank you I see all over the web that I should tie a session cookie to an ip to help stop some XSS session stealing, but I can't find HOW to do this anywhere. Can someone post some example code? Thanks! test.php Code: [Select] <?php setcookie("test", 'tester', time()+3600*24*30 , "/", ".mystagingsite1.com"); header('Location: test2.php'); ?> test2.php Code: [Select] <?php echo '<pre>'; print_r($_COOKIE); echo '</pre>'; ?> This does not work. It's not setting the cookie at all. Is there something I am doing wrong here? 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... |
