You are sending the form to its own page. This is not usually a good idea as page refresh ends up resubmitting the form
You should send to a form handler. Anyway when the page loads for the first time you are telling it to check the files variable, which obviously does not have an image element yet as nothing has been sent. If you insist on this approach you need to use a conditional structure to ascertain whether it exists or not in the first place.

Figured it ou! Turns out out i didn't include enctype="multipart/form-data" int the form tag. The problem now is that i can't access/display image from the database. Here is the updated code.

<?php
//for image upload

session_start();
$_SESSION['message']="";

$mysqli = new mysqli('localhost', 'root', '','auction');
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$item_name = $mysqli->real_escape_string($_POST['item_name']);
$item_description = $mysqli->real_escape_string($_POST['item_description']);
$item_image_path = $mysqli->real_escape_string('Images/item_img/'.$_FILES['item_image']['name']);

//make sure file is of image type
if (preg_match("!image!", $_FILES['item_image']['type'])) {
    if (copy($_FILES['item_image']['tmp_name'], $item_image_path)) {
        $_SESSION['item_name'] = $item_name;
        $_SESSION['item_description'] = $item_description;  
        $_SESSION['item_image'] = $item_image_path;
        $sql = "INSERT INTO items (item_name, item_image_path, item_description)
                VALUES('$item_name', '$item_image_path','$item_description')";
        if ($mysqli->query($sql) == true) {
            $_SESSION['message'] = "Item Upload Successful!";
        } else {
            $_SESSION['message'] = "file upload failed";
        }

    }
    else{
        $_SESSION['message'] = "file copying failed";
}
    }
     else {
    $_SESSION['message'] = "please upload gif, jpg, png";
}

}
