Question

I currently have this :
require_once(‘auth.php’);

auth.php:

    session_start();

    if(!isset($_SESSION['SESS_MERCHANT_ID']) || (trim($_SESSION['SESS_MERCHANT_ID']) == '')) {
        header("location: login-form.php");
        exit();
    }

mybadges.php:
        $mybadges = mysql_query("SELECT badge_id
        FROM badges WHERE merchant_id = $current_userid ORDER BY badge_id DESC"); 

    while ($result = mysql_fetch_array($mybadges)){

    $badge_id = $result['badge_id'];

    }

I wanted to know how I can store $result['badge_id']; in a $_SESSION array (like $_SESSION['badges']?)

Answer 1

a more sensible version of ‘auth.php’

session_start();
if(empty($_SESSION['SESS_MERCHANT_ID'])) {
    header("location: login-form.php");
    exit();
}

a more sensible version of mybadges.php:

$sql = "SELECT badge_id FROM badges WHERE merchant_id = $current_userid ORDER BY badge_id DESC"
$res = mysql_query($sql) or trigger_error(mysql_error()." ".$sql); 

in case there is only one bagde_id to store:

$row = mysql_fetch_array($res);
$_SESSION['badge'] = $row['badge_id'];

in case there are many id’s (as one cannot say for sure from your code, what you need):

$badges = array();
while ($row = mysql_fetch_array($res)) {
    $badge_ids[] = $row['badge_id'];
}
$_SESSION['badges'] = $badge_ids;

in general, to store anything an a session, just assign that anything to a session variable:

$_SESSION['badges'] = $badge_ids;

not a big deal.

a SESSION array become exectly what you wrote. $_SESSION['badges'] is a regular variable to use.

Note that you can save only scalars, arrays and objects. Not resources.
