Question

I’m having an extremely weird problem with a PHP script of mine.

I’m uploading a couple of files and having PHP put them all in one folder. I’ve have trouble with random files being sent and random ones not being sent. So I debugged it and I got a very weird result from the $_FILES[] array.

I tried it with 3 files.

$_FILES['addFile']['name'] Holds the names of the 3 files.

You’d expect $_FILES['addFile']['tmp_name'] to hold the 3 temporary names that PHP uses to copy the files, but it doesn’t. It holds just one name. The other 2 are empty strings, which generate an error whilst uploading(which I supress from being displayed)

This is very odd. I’ve tried mulitple situations and it just keeps on happening. This must be something in my settings or perhaps even my code.

Here’s my code:

$i = 0;   if (!empty($_FILES['addFile'])) {     foreach($_FILES['addFile'] as $addFile) {       $fileToCopy = $_FILES['addFile']['tmp_name'][$i];       $fileName   = $_FILES['addFile']['name'][$i];       $i++;       if(!empty($fileToCopy)){        $copyTo = $baseDir.'/'.$fileName;        @copy($fileToCopy, $copyTo) or die('cannot copy '.$fileToCopy.' to '.$copyTo);       }      }           exit(0);    } 

Since the tmp_name is empty, the if-value will be false so it’s gonna skip the die() function.

Does anybody know what might be causing this?

further info: I’m using Windows XP, running WAMP server. Never had this problem before and I can acces all maps from which I’ve tried to upload. Security settings of windows can’t be the issue I think.

Relevent, but probably not going to help: but move_uploaded_file is a (slightly) better way to handle uploaded files than copy.

Are any of the files large? PHP has limits on the filesize and the time it can take to upload them …

Better to send you here than attempt to write up what it says:
