how to retain when update files in php?
My Script is here:
<?php
if($_POST['updatesitesettings'])
{
$target = "uploads/2015/";
$target = $target . basename($_FILES['profile']['name']);
$ok=1;
move_uploaded_file($_FILES['profile']['tmp_name'], $target);
if($target == "stored/")
{
$target = "Attachment is Empty";
}
$site_name = $_POST['site_name'];
$site_description = $_POST['site_description'];
$site_tag_line = $_POST['site_tag_line'];
$contact_email_address = $_POST['contact_email_address'];
$contact_phone_number = $_POST['contact_phone_number'];
$notification_time = $_POST['notification_time'];
$meta_keywords = $_POST['meta_keywords'];
$meta_description = $_POST['meta_description'];
$currency_code = $_POST['currency_code'];
$currency_symbol = $_POST['currency_symbol'];
$show_map = $_POST['show_map'];
$copyrights_info = $_POST['copyrights_info'];
$updated_date = date('m/d/Y h:i:s a', time());
$person = $_GET['admin_id'];
$updatesett = $conn->prepare("UPDATE sitesettings SET
