<?php
    include "include/connection.php";
    if (isset($_POST['verifikasi'])){
        $appid = $_POST['appid'];
        $sql = "UPDATE tb_paru SET status='1' WHERE id_paru = '$appid'";
        $run = mysqli_query($conn, $sql);
        if($run == true){

            echo "<script>
                    alert('Application Approved');
                    window.open('index.php','_self');
                  </script>";
        }else{
            echo "<script>
            alert('Failed To Approved');
            </script>";
