Upload File

restak

Hello
When trying to upload a file using a form, is it possible to get the tmp_name and the size although the file isn't completely uploaded yet?

Thanks for your answers.

You mean while the file is being uploaded? (I'm assuming for some kind of status indicator).

I would imagine that this would require two separate scripts, since the one you're using for the file upload will be busy until the file is complete.

Yes, I attempt to build a status indicator for various files being uploaded via HTTP-POST. Two Script are necessary, I think so, too. But how can I get the temporary name of the file being uploaded?

See this link:

Yes, I know how to handle Uploads concerning the $_FILES-Array. But this methods only works when the file is uploaded and not during the transfer, you see? So I need a way to get the tmp_name as soon as I klick on the "Upload"-Button of the form, even if the file has a size 100MB.

Doing a search here for 'upload status' turned up numerous similar threads. All of them basically say you can give the appearance of a status bar, but you cannot do an accurate one. The best resource or idea I have seen so far out of all this is

a post to the PHP discussion list. See if that fits your needs.

I'm not sure there is a way to do what you're asking. PHP will not start processing the file until it has been uploaded and it has a "handle" on the file itself.

In theory, if it were a very low traffic site (perhaps one upload at a time), you could change the default temp directory (upload_tmp_dir) in your php.ini to something that will not be used for anything else, then measure the size of it by firing off a second script. You wouldn't know the total size of the incoming file, but you could provide a status like "5MB complete...10MB Complete..." Cheezy, but it's something.

It's not really that what I'm looking for, becaus it's just showing "work in progress", nothing else.

Probably you are right, I have considered the way with the upload-dir, too. I'll do this like this now.

Thanks a lot.

Hi restak,

I too have been looking into this problem

I think the only really satisfactory way to do it would be to have a Java applet (or similar) on the client side. I have found several but they were all pay-for and not good enough for me to want to hand over my cash.

Let me know how you get on with this solution. It is a problem that has been bugging me for ages.

This Flash/Javascript solution is interesting, but not perfect:

Yes, it works quite well. But the status displayed is no longer correct in case there are more people uploading large files at the same time.

But if that is not the case this is a nice solution.

It's unfortunate that the "upload_tmp_dir" directive cannot be changed by the script itself, because you could then create a dynamic directory for each upload, which could separate multiple files being uploaded simultaneously...
