Multiple file uploads to a specific folder - php

Question

I'm attempting to create a plugin on wordpress and I need to upload multiple images to a specific folder on the server...
I currently have
<form method="post" enctype="multipart/form-data">
<input type="file" name="my_file[]" multiple="multiple">
<input type="submit" value="Upload">
</form>
And this is the code that reads and should upload the files...
if (isset($_FILES['my_file'])) {
$myFile = $_FILES['my_file'];
$fileCount = count($myFile["name"]);
for ($i = 0; $i < $fileCount; $i++) {
$name = $myFile["name"][$i];
$error_msg = $myFile["error"][$i];
$success = move_uploaded_file($myFile["tmp_name"][$i], $photo_dir."/".$name);
if ($success) {
echo $name ." uploaded<br>";
} else {
echo $error_msg;
}
}
}
Is there a way to get it to report an error - at the moment if the file name already exists then it jsut overwrites the old version...

When you do a upload of files PHP store the files in a temporary folder.
You have to move the file from temporary folder to the folder that you want to store the files.
Here is an example using your code:
if (isset($_FILES['my_file'])) {
$myFile = $_FILES['my_file'];
$fileCount = count($myFile["name"]);
// The folder that you want to store the file
$folderName = 'tmp/';
for ($i = 0; $i < $fileCount; $i++) {
$fileName = $myFile["name"][$i];
$success = move_uploaded_file($myFile["tmp_name"][$i], $folderName . $fileName);
if ($success) {
echo 'File ' . $fileName . ' uploaded!<br>';
}
}
}
