PHP - Sql Errors As I Attempt Split Data From A Session Into Two Tables

How can I split this data and then remove it? I need to split data by ; then split each one of those.
$data = "page=1&data=1:21;2:34;5:57&a=yes";

So I will get:

$category[0] = 1;
$sub_category[0] = 21;
$category[1] = 2;
$sub_category[1] = 34;
$category[2] = 5;
$sub_category[2] = 57;

No matter what I try, I keep getting a session error.

Can somebody look at this code and see what the problem?

Code: [Select]
<?php
ob_start();
session_start();
ini_set("display_errors",'ON');
require_once('../lib/config.db.php');
require_once('../inc/auth_func.php');
$message = '';
//echo DECRYPT('w9Ti2cqStdDU2w==');
if (!empty($_POST)) {
$post = array();
foreach ($_POST as $key => $value) {
$post[$key] = mysql_real_escape_string(strip_tags(html_entity_decode($value)));
}

$username = $post['username'];
$password = ENCRYPT($post['password']);

$sql = sprintf("SELECT id, name,transactionid FROM app_logins WHERE username = '%s' AND password = '%s' AND active = 1", $username, $password);
$result = mysql_query($sql) or trigger_error(mysql_error());

if ($result && mysql_num_rows($result) > 0) {
$row = mysql_fetch_object($result);
$sqlapp = "SELECT * FROM app_queue WHERE transactionid={$row->transactionid} ORDER BY appid ASC LIMIT 1";
$rsapp = mysql_query($sqlapp);
if($rsapp && mysql_num_rows($rsapp) > 0){
$rowapp = mysql_fetch_object($rsapp);
$_SESSION['default_appid'] = $rowapp->appid;
}
$_SESSION['app_login_id'] = $row->id;
$_SESSION['login_name'] = $row->name;
$_SESSION['tid'] = $row->transactionid;
$location = !empty($post['from']) ? urldecode($post['from']) : 'index.php';
//ob_clean();
header("location:{$location}");

} else {
$message =  '<p style="color:red;">That username and password<br />combination match none of our logins</p>';
}
}
?>

Thank you in advance

Hey,

I'm having a bit of trouble with some coding it's coming up with the following error message;

I cannot see any previously defined sessions on this coding, can anybody help me please. I am hosting this section as a sub domain on a host that has anopther site, but the files are in a seperate folder so I don't think thats affect it. Any ideas??

I apologize to keep posting this in different topics, but since I can't edit my last topic to fit this one; I must.

Code: (function.php) [Select]
<?php
error_reporting(-1);
ini_set('display_errors', 1);

function check() {

$admin="test";
$pass="test";

if (isset($_POST["user"]) && $_POST["user"] == $admin && isset($_POST["pwd"]) && $_POST["pwd"] == $pass) {
  sesshin(); }
}
function sesshin() {

session_start(); 
$_SESSION['user'] = "test";

if ($_SESSION['user'] = "test") {
header('Location: output.php'); }
else {
header('Location: index.html'); }
}
?>

I get the following errors when I try to login.

Code: [Select]

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /srv/www/deadnode.com/public_html/function.php:25) in /srv/www/deadnode.com/public_html/function.php on line 15

Warning: Cannot modify header information - headers already sent by (output started at /srv/www/deadnode.com/public_html/function.php:25) in /srv/www/deadnode.com/public_html/function.php on line 1

I've just confused myself into doing this. Maybe I can do all of this in one function? Check(), should look to see if the form information is correct. If so, then it should start the session and proceed to the output.php page. The other thing I'm trying to figure out is how to block public view of output.php if you havent logged in.

Hello All,

I am trying to get some info from my membership script (Amember_Pro) into an iframe within a product page.
Inside iframe I have the following code

Code: [Select]
<?php
session_start();
?>Some HTML Code here...
Code: [Select]
<?php
$user = $_SESSION['_amember_user'];
print "$user[member_id]";
?>
Above code is able to print the "_amember_user" ID successfully to the page but on top pf the iframe I get a session error.
Code: [Select]
"Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/tb/public_html/product1/link1.php:1) in /home/tb/public_html/product1/link1.php on line 2"
Does anyone know why this is happening?
I have made sure that there is no space or code before <?php session_start(); ?>
There is a help guide at http://manual.amember.com/AMember_Session_Variables that I used to create code above.
