[SOLVED] Sessions

[marklarah]

Code:

<?
include 'db.php';
if (isset($_POST['user'])){
$name = htmlentities($_POST['user']);
$pass = md5($_POST['pass']);
$result = mysql_query("SELECT * FROM `Players` WHERE `name` = '$name' AND `password` = '$pass'");
$num = mysql_num_rows($result);
if ($num == 1){
$row = mysql_fetch_array($result);
$key = $row['s_key'];
setcookie("login", $key, time()+(60*60*24*365));
$s = 1;
}else{
$fail = "<br><b><i><font color=\"red\">FISSION MAILED: Try Again</font></i></b>";
}
}else{
$nl = 1;
}
?>

 

Problem

I try to set the cookie, and I know it sets, as it lets me onto my page which has a "if(isset(....."

 

Trouble is, Im echoing $key and $_COOKIE["login"] and printing all my cookies. I see $key (which is good).

I DONT see $_COOKIE["login"] which should be the same as $key and i dont see the cookie appear in the printing of all my cookies.

 

???

Try using print_r($_COOKIE) to see if it's being set properly.

I am (I said i am) and its not.

Hmm, I'm not positive but try this:

 

$result = mysql_query( "SELECT * FROM Players WHERE name = {$name} AND password = {$pass}");

I can't at all get this to work. HELP!!!!

use sessions?

 

$_SESSION['login'] = $key

[marklarah]

Sessions only work for...one session.

Not if you put session_start() on the top of every file and change the session timeout value in php.ini.  Cookies are horrid for login systems, no offense.

Back to your first post, since you did not show where you were trying to display the cookie and expected $_COOKIE["login"] to be set, I will guess it was on the page where you were setting the cookie. If so, from the manual -

 

Cookies will not become visible until the next loading of a page that the cookie should be visible for

 

The $_COOKIE array is set when a page is requested and the browser sends the cookies to the server. Until you refresh a page or goto a different page $_COOKIE["login"] won't exist in the $_COOKIE array.

 

If you are still not receiving the cookie, it is probably due to the path or host part of the domain changing or you are not actually setting the cookie due to a header problem.

I'd bet money that it's the former.  He probably is trying to view the cookies on that page. >_>

You are 100% correct...how n00bish of me. :( Perhaps pin this topic for when others make this mistake. Oh and I don't have access to php.ini.
