Code has no errors but it's not showing any data

I was working on a wallpost script, the page has no errors, i've check with the database (the query worked there) and i've tried everything i think i can, but it just will not work. I don't know what else to do, if you have any ideas to why it won't work, show me. PS: the database has some dummy data in it.

<?php
    include 'inc/dbc.php';
    include 'inc/functions.php';

    if(isset($_GET['user']) && !empty($_GET['user'])) {
        $username = $_GET['user'];
    } else {
        $username = $_SESSION['username'];
    }

    $my_name = $_SESSION['username'];
    $firstname = getuser($username, 'firstname');
    $middlename = getuser($username, 'middlename');
    $lastname = getuser($username, 'lastname');
    $aboutme = getuser($username, 'aboutme');
    $email = getuser($username, 'email');
    $dob = getuser($username, 'dob');
    $address = getuser($username, 'address');
    $website = getuser($username, 'website');
    $country = getuser($username, 'country');
    $city = getuser($username, 'city');
    $state = getuser($username, 'state');
    $phone = getuser($username, 'phone');
    $gender = getuser($username, 'gender');
    $rank = getuser($username, 'rank');
    $avatar = getuser($username, 'avatar');
    $reg_date = getuser($username, 'reg_date');
?>
<?php
    if (loggedIn() == true) {
        $chech_posts = mysqli_query($mysqli, "SELECT * FROM wallposts WHERE posted_to = '$username' AND deleted = 0 ");
        $check = mysqli_num_rows($chech_posts);

        if ($check == false) {
            echo '<li>Error Getting posts</li>';
        } else {
            while ($run = mysqli_fetch_array($check)) {
                $post_id = $run['post_id'];
                $postby = $run['posted_by'];
                $postto = $run['posted_to'];
                $post = $run['post'];
                $post_date = $run['post_date'];
                $post_time = $run['post_time'];

                $p_avatar = getuser($postby, 'avatar');
                $p_first = getuser($postby, 'firstname');
                $p_last = getuser($postby, 'lastname');
