PHP - Setting A Cookie

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...

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 

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"); 

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...

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.

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...

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

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 to get the cookie value,when we login for a website,also how to access the site by using the cookie values?

Hi again all,

I wondered if anyone could help again (sorry).  I have one single page which I would like to record a cookie when the user hits submit. The next time the user visits the site, I want it to recall the cookie and put the value in the textbox on the page. I think I have it storing the cookie (not sure though), but I am having trouble getting it to recall in the text box.  I wondered if someone could look at this code and see where I am going wrong or help with what I need to add.  New to PHP so having trouble getting my head around things.  Thanks in advance.

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?
