Post message php, error, please suggest a change

question :


This is my code of my status.php file but on posting status it is showing only one thing i.e. type_unknown but I am not sure why it is not functioning properly. and type_unknown is also a command in this coding please go through this command and after that suggest any change you want to.

 <?php
    include_once("../php_includes/check_login_status.php");

Answer

If the problem is appearing in this line:

 if($_POST['type'] != "a" || $_POST['type'] != "c"){

Then, it means that the you do not have an input form with the name type inside it, or the post data may not be transferred at all. So, check your HTML form if it has input called type
