session problems

[TobesC]

im trying to run sessions, but when i log in and go to the search page, it doesnt recognize the existing session, but when i do a search where i post variables back to that page, it recognizes the session data the second time. anyone know the problem?

You will need to post your code

here is the authentication i use.

 

login script:

-user submits email and password

 

<?php

session_start();

if (!isset($_SESSION['tries'])) {

session_register($_SESSION['tries']);

$_SESSION['tries']=0;

}

mysql_connect;

mysql_select_db;

$email=trim(strip_tags($_POST['email']));

$password=trim(strip_tags($_POST['password']));

if ($email!="") {

$result=mysql_query("SELECT * FROM `users` WHERE `email`='$email'");

$row=mysql_fetch_array($result);

if ($password==$row['password']) {

session_register($_SESSION['uid']);

$_SESSION['uid']=$row['uid'];

session_register($_SESSION['email']);

$_SESSION['email']=$email;

session_register($_SESSION['session']);

$_SESSION['session']=session_id();

header ("location: ../index.php");

}

else {

$_SESSION['tries']=$_SESSION['tries']+1;

if ($_SESSION['tries']>2) {

header ("location: ../reset.php");

}

else {

header ("Location: ../index.php");

}

}

}

else {

header ("Location: ../index.php");

}

?>

 

authentication check (at beginning of each page of site):

 

session_start();

$now=session_id();

$session=$_SESSION['session'];

if ($now==$session) {

$logged="y";

}

if $logged equals y, other options are present.

 

any help would be greatly appreciated. this is driving me crazy.
