setting cookie

[SUNIL16]

Hi Friends,

 

I set cookie like below after the user login.

<?php
require "config.php";  

$username=$_REQUEST["uname"];
$password=md5($_REQUEST["password"]);



$sql="SELECT usersid,username,password FROM users WHERE username='$username' and password='$password'";
$result=mysql_query($sql);

$rows=mysql_fetch_array($result);
$memberid=$rows['usersid'];
$count=mysql_num_rows($result);

if($count == 1) {
setcookie("myusername", "$username",time()+3600);
include("welcome.php");
exit();
} 
else {
include("re_login.html");
exit();
}

 

But now the problem is the user can login but the cookie is set only after 2logins means he has to login again to post any thing. what is the problem with cookie...

cookies cannot be used on the same execution that created them. use either a Header("location: ./url.php"); redirection, or log them in as you create the cookie, (rather than relying on the cookie to be there).
