PHP - Some Cookie Questions

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,
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;

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

I've been coding PHP for some time and would consider myself to be at an intermediate level. I can write code to do what I need but it's probably not the best way to do it. I rarely see any code that I am not able to read, understand, or follow. I've created modifications for everything from vBulletin, WordPress, Kayako Support Suit, Magento, and more.

However, I've never really built a strong understanding around OOP. For example, let say you have the following classes:
_main
  -  db
  -  admin
  -  -  modules
  -  -  -  dashboard

How would you share the db connection with the dashboard class? I've been trying to read up on Dependency Injections and Singletons but I haven't found an article that has explained it on a level that I can understand. I get a feeling that most people who use OOP in PHP have a background in Java or C++ and are much more familiar with everything.

Could someone please explain this to me in simple terms or link me to an extremely well explained article that I'd be able to understand without a background in computer science?
Thanks

Hello everyone, I have been doing web developing for a little while and just recently decided to make the leap to developing standalone applications.  I started learning C++ and JAVA for this purpose, but quickly learned that PHP can also be used to this end, and since I am quite familiar with PHP, I thought it would make sense to start with PHP GTK.  But before I jump right in, I have a few questions that I would greatly appreciate some answers for:

Does PHP have any significant advantages/disadvantages over lower level languages such as C++ ?  I would imagine that PHP being originally designed for web programming would be less suited for stand alones.

I'm a little confused as to whether the GTK is a graphical user interphase software, the likes of QT and Netbeans,  or is it a markup language like HTML, where the widgets are generated with text commands?  Please I need a little clarification on that.  Also are there any other tools that need to be downloaded to get started besides the GTK?

Finally, am I supposed to learn OOP PHP to get going or is traditional procedural PHP sufficient?


Answers to any or all of the above questions and any other advice would be highly appreciated.

Thanks.

Howdy,

I am new to SEO. Could you please help me? 

1. I like to post programming tutorials to both my website & various programming forums. Is that going to screw up my website's ranking in Google?

2. My editor of my history website who sometimes posts essays there also posts them in some history forums. Is that bad for SEO?

3. I made a Facebook page for my history website. It says there "Promote your page" basically you pay $5 for around 100 likes. Has anyone tried that? Does it work? Because $5 seems like little money for additional 100 likes which will increase the traffic considerably.

Thank you so much for the help!

Hi. I'll like to ask few questions about PHP, as I think they are related to it.   I've came across some webpages, what I've spotted is that a webpage displays content but each "page" has different argument and there is no filename. For example: "http://www.website.com/?home" is home-like webpage, by changing "/?home" to "/?anotherpage" land me on some other webpage on their website and so on. My question is how is it done? Is it done from PHP? Another question I wanted to ask is.. I went on InvisionPower.Board forum (such as this PHP Freaks  ). How to force "folders" to be displayed as "files"? For example: "http://forums.phpfre...ks-on-facebook/" which links to a thread.   Thanks in advance 

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"
 

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.

When a cookie expires what happens to it?

Is it physically removed from your hard-drive?

Hello All

    I wrote a tiny piece of cookie code (to set and record cookies and hits) that works pretty well but seems to have a bug in it that I cannot figure out. First, here is the code:

Code: [Select]
<?php
$my_cookie = (isset($_COOKIE['my_cookie'])) ? true : false;

$countFile = "./data/count.txt";
$cookieFile = "./data/cookie.txt";

$dateTime = date('Y-m-d\,H:i:s\,U\,T\,O\G\M\T');
$remoteIPAddress .= $_SERVER['REMOTE_ADDR'];
$remoteUserAgent .= $_SERVER['HTTP_USER_AGENT'];

$cookieVal = $dateTime;
$cookieVal .= ",";
$cookieVal .= $remoteIPAddress;
$cookieVal .= ",";
$cookieVal .= $remoteUserAgent;
$cookieVal .= "\r\n";

    if(!$my_cookie){
     // read the visit counter
     $countHandle = fopen($countFile, 'r');
     $visitCount = intval(trim(@fread($countHandle, filesize($countFile))));
     fclose($countHandle);

     // incremenet the visit counter
     $visitCount++;

// write the new visit count and cookie value to their respective files
     $countHandle = fopen($countFile, 'w');
     $cookieHandle = fopen($cookieFile, "a+b");

if(!preg_match('/bot/',$remoteUserAgent)){
     fwrite($countHandle, $visitCount);
     fwrite($cookieHandle, $cookieVal);
     }

     fclose($countHandle);
     fclose($cookieHandle);

     setcookie("my_cookie", $cookieVal, time()+31556926);
    }
    else{
     // read the visit counter
     $countHandle = fopen($countFile, 'r');
     $visitCount = fread($countHandle, filesize($countFile));
     fclose($countHandle);
    }
?>

What is happening is that sometimes, not every time, but, sometimes my cookie.txt count gets a 0 (zero) written back to it and I can't figure out why. Can anybody see anything in there that would have this effect? Like I said, it only gets zeroed out from time to time.

Thanks to all for taking the time to read.   

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?

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!
