File Upload Not working on Mac - php

Question

I have a csv upload script that works perfectly on my PC and other PC's have been tested as well. I have a client who is trying this script on their Mac and it returns an error: Error no file selected.
The permissions on the upload folder are 755.
Really need to find out the cause of this. You can see my script and form below.
define("UPLOAD_DIR", "/home/path/public_html/uploads/".$company."/");
$message = null;
$allowed_extensions = array('csv');
if(!empty($_FILES['file'])){
if($_FILES['file']['error'] === 0){
$file = explode(".", $_FILES['file']['name']);
$extension = array_pop($file);
// ensure a safe filename
$name = preg_replace("/[^A-Z0-9._-]/i", "_", $_FILES['file']["name"]);
// don't overwrite an existing file
$i = 0;
$parts = pathinfo($name);
while (file_exists(UPLOAD_DIR . $name)) {
$i++;
$name = $parts["filename"] . "-" . $i . "." . $parts["extension"];
}
if(in_array($extension, $allowed_extensions)){
if(move_uploaded_file($_FILES['file']['tmp_name'],
UPLOAD_DIR . $name)){
if(($handle = fopen(UPLOAD_DIR . $name, "r")) !== false){
$keys = array();
$out = array();
$line =1;
while(($row = fgetcsv($handle, 0, ',', '"')) !== false){
foreach($row as $key => $value){
if($line === 1){
$keys[$key] = $value;
}else{
$out[$line][$key] = $value;
}
}
$line++;
}
fclose($handle);
if(!empty($keys) && !empty($out)){
foreach($out as $key => $value){
$sql = "INSERT INTO ".$company."(id,prefix,fullname,last_name,business,address1,address2,address3,town,county,postcode,email,website,telephone1,telephone2,telephone3,landing_page,assigned_to,question1,question2,question3,question4,question5,question6,date,status,leadtype,file,gclid,leadid,tostep,ip,client_xp)VALUES(?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)";

Answer 1

Ok so this ended up being a really simple solution by changing the first line of code to this
define("UPLOAD_DIR", "/home/path/public_html/uploads/$company/");
The inverted commas were closing the string before the company variable could be used, making the upload path invalid.
