PHP - Cookie Code

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

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;

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...

Ok I have NEVER had problem like this before.

First of all, I am not that great with cookies or headers. But I know how to set cookies & sessions & how to use them.

Any way, this is the most important feature & page on my app. Its for the register page, it sets a cookie that is needed to prevent fraud.

I did the development of this script on my local server & this is my first time testing it on a real server.

My issue is, I keep getting the damn headers already sent error;

Code: [Select]
Warning: Cannot modify header information - headers already sent by (output started at /../../..//mysite.com/admin/includes/linkmysql.php:2) in /../../../mysite.com/reg.php on line 36
I literally tried everything. I completely rewrote the page to work around this. I cannot stress enough how important this cookie is.

I dont udnerstand. The php is b4 all the html, etc etc. There should be no other "headers being sent".

Heres the code;

<?php


require_once 'is_email.php';

$result = is_email(@$email, true, true);
if (isset($_POST['register_clicked']) && $_POST['register_clicked']==1)
{
$uname = $_POST['uname'];
$upasswd = $_POST['passwd'];
$email = $_POST['email'];




if (!(strlen($uname) > 0 && strlen($uname) < 31))
echo '<td colspan="3" align="center" class="FormError"> USERNAME length must be between 1 and 30! </td>';
else if (!(strlen($upasswd) > 0 && strlen($upasswd) < 41))
echo '<td colspan="3" align="center" class="FormError"> PASSWORD length must be between 1 and 30! </td>';
else if ($upasswd != $_POST['passwdconf'])
echo '<td colspan="3" align="center" class="FormError"> PASSWORD doesn\'t match! </td>';


else if (!is_email($email)) echo "<td colspan='3' align='center' class='FormError'>{$email} is not a valid email address! (result code $result)</td>";
else
{
include_once('admin/includes/linkmysql.php');
include('admin/includes/func.php');
if (!newuser($uname, $upasswd, $email))
echo "<td colspan='3' align='center' class='FormError'>Username already in use!</td>";

else
{
echo '<strong><font color="black">Registration Completed!</font></strong>';
$value = "no-delete";
setcookie("Muffins", $value, mktime (0, 0, 0, 12, 31, 2015));

#if (isset($_POST['autologin']))
#{

add_login($uname);
$_SESSION['login_name'] = $uname; 
?>
<!--<script language="javascript" type="text/javascript">
window.location.href = "index.php?a=home";
</script> -->
<?php
}
}
}

?>
                    <?php
if (isset($_COOKIE['Muffins']))
{
Header ('Location: http://mysite.com/index.php?a=noreg');
}

?>

line 36 is obviously the line with the setcookie. I have no idea why it is referencing the include file, it has two lines of code that defines the mysql connections.

This code is at the top of the page, before all the HTML etc. NO reason why it should be giving me header errors rigght!?? Im having the same issue with another page. I ban users thru setting a value in a mysql table, when the "system" notices the ban value is set, it redirects them to an account banned page using a header. BUT ITS THE SAME ******** THING!!!!!

NEVER in my YEARS of coding have I ran into such AN ANNOYING & SENSELESS ISSUE!

Sorry I am just SO frustrated, due to this I have not worked on this in days I pretty much gave up. I cannot launch this site that I have been working on for years without this working.

THANK YOU FOR ALL YOUR HELP!!! Much appreciated.

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 trying to setup a simple password protected site with a cookie so that users that have entered the password wont have to enter it again for 1 month. so I have a simple index.php page with the passowrd field on it in the root directory. then my site is in a sub directory /cms/ and the index.php page there checks for the $_POST value to set the cookie and let the user continue on.

Like this:
<?php 
//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);
}



defined( '_VALID_MOS' ) or die( 'Restricted access' );

//check if user has not entered password
if (!isset($_COOKIE['fpass']) || $_COOKIE['fpass'] == "") header('location: http://www.example.com');
//check if the user has a cookie set but is on a new session
if (isset($_COOKIE['fpass']) && !isset($_POST['fpass'])) header('location: http://www.example.com/disclaimer.php');

...
The disclaimer.php page is actually the default landing page that users need to start on (after entering a password that is).

Couple of problems:
This just loops back to the disclaimer page how do I send the user to the disclaimer page at the beginning of each session even if the Cookie is set
thanks for any help

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>

</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

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

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?

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

<?

$name = $_GET['name'];
$game2 = "2":

setcookie('game_".$name."',$game2, time()+3600); 

?>

would this work?
if not how can it be done?

cheers matt
