[RESOLVED] Recalling Session Variables throughout site

[oddball25]

The problem was that i was telling php that the session variable was the result of the posted data, so when i went back to info.php without posted anything, they became 0, got it with this code from the help off another forum:

<?php
session_start();

if(isset($_POST['number']) && !empty($_POST['number'])) {
    $_SESSION['num'] = $_POST['number'];
}

echo $_SESSION['num'];
?>
