Android Question Need server side code when "PostString" is used in B4a

    Request = $"id=${someid}&variable1=${somevariable1}"$
    j.PostString("yoururl/mypage.php", Request)

<?php

    $_id = isset( $_POST["id"] ) ? $_POST["id"] : null; // Check if id POST is set
    $_var1 = isset( $_POST["variable1"] ) ? $_POST["variable1"] : null; // Check if variable1 POST is set

    If (isset($_id))
    {
        //$id is set! 
        //Do something here
        echo $_var1;
        
    }else{
        
        header("HTTP/1.0 400 Bad Request");
        //exit('Not found');
    }   
?>
