    include('validation.php');
    include('header.php');

    $PID = $_GET['PID'];
    $q_getpackage = "SELECT * FROM packages WHERE PID=$PID";
    $r_getpackage = mysql_query($q_getpackage,$connection);

SQL 语句未正确执行。运行echo mysql_error()后mysql_query()看看为什么不，检查输出，并修复它告诉你的任何内容。

（另外，将有关输入验证/准备好的语句/mysqli 的标准警告作为给定的）
