Cookie Problem

[Berk]

<?
include ("header.php");
if(isset($HTTP_POST_VARS['go']))
{
if(isset($HTTP_POST_VARS['user']) && isset($HTTP_POST_VARS['password']) && isset($HTTP_POST_VARS['email']))
{
$user= $HTTP_POST_VARS['user'];
$pass = $HTTP_POST_VARS['password'];
$email= $HTTP_POST_VARS['email'];
$password = md5($pass);
mysql_query("SELECT FROM user WHERE user= '$user'");
if (mysql_affected_rows() > 0)
{
echo "User Exists";
exit;
}
mysql_query("SELECT FROM user WHERE email= '$email'");
if (mysql_affected_rows() > 0)
{
echo "Email is already in user";
exit;
}
mysql_query("INSERT INTO user (user,password,email) VALUES ('$user','$password','$email')");
print "Kayýt Tamam Patron";
$cookie = mysql_query("SELECT * FROM user WHERE user= '$user'");
$data = mysql_fetch_array($cookie);
setcookie("cookie_username", $data[user], mktime(0,0,0,1,1,2030));
setcookie("cookie_password", $data[password], mktime(0,0,0,1,1,2030));
}
else {
print "Perhaps something is wrong with this?";
}
}
?>

Now It inserts the info to mysql tahts ok but then what is this?

Notice: Use of undefined constant user - assumed 'user' in C:\Dev\chronicler.php on line 27

cookies must be set BEFORE any output is displayed. That means you have to set the cookies before you start displaying any text or images or anything.

To accomplish what I think you are trying to do, just set a variable in place of the echos, and then display it at the bottom.

the notice is because your php.ini file has notices turned on. turn them off.

Try it this way:

<?
if(isset($HTTP_POST_VARS['go']))
{
if(isset($HTTP_POST_VARS['user']) && isset($HTTP_POST_VARS['password']) && isset($HTTP_POST_VARS['email']))
{
$user= $HTTP_POST_VARS['user'];
$pass = $HTTP_POST_VARS['password'];
$email= $HTTP_POST_VARS['email'];
$password = md5($pass);
mysql_query("SELECT FROM user WHERE user= '$user'");
if (mysql_affected_rows() > 0)
{
echo "User Exists";
exit;
}
mysql_query("SELECT FROM user WHERE email= '$email'");
if (mysql_affected_rows() > 0)
{
echo "Email is already in user";
exit;
}
mysql_query("INSERT INTO user (user,password,email) VALUES ('$user','$password','$email')");
print "Kayýt Tamam Patron";
$cookie = mysql_query("SELECT * FROM user WHERE user= '$user'");
$data = mysql_fetch_array($cookie);
setcookie("cookie_username", $data[user], mktime(0,0,0,1,1,2030));
setcookie("cookie_password", $data[password], mktime(0,0,0,1,1,2030));
}
else {
print "Perhaps something is wrong with this?";
}
}
?>
<?
include ("header.php");
?>

I'm not sure what is in the header.php file...but

If you read on cookies, you will notice that no HTML can be passed with the page that is setting the cookie, because the cookie "sets" the page.

It is often necessary to "set" the cookie in the very beginning before doing any queries or anything like that. Sometimes it is tricky getting them to work just write. I have had to rewrite and rethink my script just to get cookies to work.

Read up on sessions too. It might work for you better

OK I got the idea;
by the way; header.php is just a file to connect to sql and select db.
I just didn2t want to write them into this script so I created a header.php
Blessed Be!

so include the header after you set the cookies.
