Keep getting two errors with my PHP file upload system - php

Question

I am setting up a file upload service on my website. Here is what I got so far,
upload.php
<form action="uploader.php" method="post" enctype="multipart/form-data">
<input type="file" name="myFile">
<br>
<input type="submit" value="Upload">
</form>
uploader.php
<?php
define("UPLOAD_DIR", "/uploads");
if (!empty($_FILES["myFile"])) {
$myFile = $_FILES["myFile"];
if ($myFile["error"] !== UPLOAD_ERR_OK) {
echo "<p>An error occurred.</p>";
exit;
}
// ensure a safe filename
$name = preg_replace("/[^A-Z0-9._-]/i", "_", $myFile["name"]);
// verify the file is a GIF, JPEG, or PNG
$fileType = exif_imagetype($_FILES["myFile"]["tmp_name"]);
$allowed = array(IMAGETYPE_GIF, IMAGETYPE_JPEG, IMAGETYPE_PNG);
if (!in_array($fileType, $allowed)) {
// file type is not permitted
echo "<p>Unable to save file.</p>";
exit;
}
// don't overwrite an existing file
$i = 0;
$parts = pathinfo($name);
while (file_exists(UPLOAD_DIR . $name)) {
$i++;
$name = $parts["filename"] . "-" . $i . "." . $parts["extension"];
}
// preserve file from temporary directory
$success = move_uploaded_file($myFile["tmp_name"],
UPLOAD_DIR . $name);
if (!$success) {
echo "<p>Unable to save file.</p>";
exit;
}
// set proper permissions on the new file
chmod(UPLOAD_DIR . $name, 0644);
}
There is a folder in my directory called uploads, I want my files to upload to there.
However when running it using XAMMP, I try and upload a image called example.png and it comes up with the following errors.
Warning: move_uploaded_file(/uploadsexample.png): failed to open stream: Permission denied in C:\xampp\htdocs\assembly\uploader.php on line 37
Warning: move_uploaded_file(): Unable to move 'C:\xampp\tmp\phpBAE5.tmp' to '/uploadsexample.png' in C:\xampp\htdocs\assembly\uploader.php on line 37
Unable to save file.
If you could help me solve my issue I would be very grateful! thanks.

Answer 1

Add a trailing slash / for
define("UPLOAD_DIR", "/uploads");
^ missing slash
change it to:
define("UPLOAD_DIR", "/uploads/");
Notice the error you got => to '/uploadsexample.png'
and in
Warning: move_uploaded_file(/uploadsexample.png):
^
it's missing a slash after uploads, between uploads and the filename.
Plus, just to be on the safe side, if that still throws you an error that it won't let you upload with another "permission denied" message, make sure that the folder is indeed writeable with proper write permissions set for it.
N.B.:
You may need to modify /uploads/ to uploads/ or ../uploads/ depending on the script's execution location.
