    functions should return its local value:

    function h()
{
    $randomchar = str_shuffle('abcdefghjklmnopqrstuvwxyzABCDEFGHJKLMNOPQRSTUVWXYZ234567890!$%^&!$%^&');
    return substr($randomchar, 0, 12);
}

    then you should call function:

    <input type="text" id="lname" name="pass" value="<?php echo h();?>"><br><br>

    I think you need to call the function instead.
    <input type="text" id="lname" name="pass" value="<?php echo h(); ?>"><br><br>

    Also make sure that the helper.php file is loaded.
