PHP file not uploading to localhost - php

Question

I've set up an XAMPP server and trying to upload image files using a custom admin page. The page works fine when I set it up on a online server running ubuntu.
But when trying the same script in localhost gives me the following error.
Warning : move_upload_file(../img/products/fw000001.jpg) : failed to open stream. No such file or directory in C:\xampp\htdocs\OBS\store\kish\bin\functions.php on line 64
Here is the file upload part of functions.php
function upload_image($image,$code)
{
define("UPLOAD_DIR", "../img/products/");
if (!empty($image)) {
$myFile = $image;
if ($myFile["error"] !== UPLOAD_ERR_OK) {
return null;
}
//check if the file is an image
$fileType = exif_imagetype($_FILES["image"]["tmp_name"]);
$allowed = array(IMAGETYPE_GIF, IMAGETYPE_JPEG, IMAGETYPE_PNG);
if (!in_array($fileType, $allowed)) {
exit();
}
// ensure a safe filename
$name = $myFile["name"];
$parts = pathinfo($name);
$extension = $parts["extension"];
$savename = $code . "." . $extension;
// don't overwrite an existing file
$i = 0;
if(file_exists(UPLOAD_DIR . $savename)) {
unlink(UPLOAD_DIR . $savename);
}
// preserve file from temporary directory
$success = move_uploaded_file($myFile["tmp_name"],
UPLOAD_DIR . $savename);
if (!$success) {
exit();
}
else
{
return $savename;
}
// set proper permissions on the new file
chmod(UPLOAD_DIR . $name, 0644);
}
}

Answer 1

I'm not pretty sure about directory separator. Directory separator is represent with (/) on Linux based OS. Widows is using ( \ ) for directory separator. So, please change this line and tested it.
define("UPLOAD_DIR", "../img/products/");
to
define("UPLOAD_DIR", "..".DIRECTORY_SEPARATOR."img".DIRECTORY_SEPARATOR."products".DIRECTORY_SEPARATOR.");

Change this line
// preserve file from temporary directory
$success = move_uploaded_file($_FILES["image"]["tmp_name"],UPLOAD_DIR . $savename);
