You can only select the id
column because that is all you have in the query.
Try something like this
if (isset($_SESSION['id'])) {
$presh = $_SESSION['id'];
$stmt = $pdo->prepare("SELECT id, karmacurrent FROM users WHERE id = :id");
$id = $presh;
$stmt->execute(
array(
':id'=>$id
)
);
$accountinfo = $stmt->fetch(PDO::FETCH_ASSOC);
}
Basically you were only retrieving the ID
from the table instead of the other columns.
