خطا در includ

سلام ببخشید من هر چه فکر کردم نفهمیدم مشکل این چیه ؟

<?php 
session_start();
include "../database/pdo_connection.php";
include "../database/jdf.php";
if (isset($_POST['sub'])) {
  $title=$_POST['title'];
  $caption=$_POST['caption'];
  $writer=$_POST['writer'];
  $date=jdate("Y/m/d");
  $image=$_POST['image'];
  $result=$conn->prepare("INSERT INTO posts SET title=?, caption=?, writer=?, date=?, image=?");
  $result->bindValue(1,$title);
  $result->bindValue(2,$caption);
  $result->bindValue(3,$writer);
  $result->bindValue(4,$date);
  $result->bindValue(5,$image);
  $result->execute();
}

if (!isset($_SESSION['user'])) {
  header("location:../login.php");
}

?>
