Large file uploads from web pages

I code primarily in PHP and Perl. I have a client who is insisting on seeking video submissions (any encoding) from the public via one of their pages rather than letting YouTube do its job.

Server in question is a virtual machine and I can adjust ini setting开发者_Go百科s for max post, max upload size etc as needed.

My initial thought is to use a Flash based uploader with PHP on the back end but I wondered if someone might have useful advice and experience on the subject?

Doing large file transfers of HTTP is not usually fun -- but sometimes it's necessary.

For large files, you'll definitely want to provide some kind of progress gauge for end-users.

There are flash-based tools that do this (swfUpload comes to mind).

If you want to avoid flash and do it with pretty html/javascript/css, you can leverage PHP's APC extension, which for some reason provides support for getting upload status from the server, as explained here

You can adjust the post size and use a normal html form. The big problem is not Apache, its http. If anything goes wrong in the transmission you will have no way to detect the error. Further more there is no way to resume the transfer. This is exactly why BitTorrent is so popular.

I don't know how against youtube your client is, but you can use their api to do the uploads from a page on your site. http://code.google.com/apis/youtube/2.0/developers_guide_protocol.html#Uploading_Videos

See: browser based uploading.

For web-based uploads, there's not many options. Regardless of web platform, web server, etc. you're still transferring over HTTP. The transfer is all or nothing.

Your best option might be to find a Flash, Java, or other client side option that can chunk files and upload them piecemeal, then do a checksum to verify. That will allow for resuming uploads. Unfortunately, I don't know of any such open source component that does this.

Try to convince your client to change point of view.

Using http (and the browser, hell, the browser!) for this kind of issue is rarely a good deal; Will his users wait 40 minutes with the computer and the browser running until the upload is complete?

I dont think so.

Maybe, you could set up a public ftp account, where users can upload but not download and see the others user's files.. then, who want to use FTP software can, who like to do it via browser can too.

The big problem dealing using a browser is that, if something go wrong, you cant resume but have to restart from zero again.

the past year i had the same issue, i gave a look to ZUpload , but i didnt use it so i can suggest (we wrote a small python script that we send to our customer; the python script create a torrent of the folder our costumer need to send to us, and we download it via utorrent ;)

p.s: again, sorry for my bad english ;)

I used jupload. Yes it looks horrible, but it just works.

With that said, it's still a better idea to convince the client that doing so is stupid.

I would agree with others stating that using HTML is a poor option. I believe there is a size limitation using Flash as well. I know of a script that uses a JavaScript Applet to perform an actual FTP transfer. It is called Simple2FTP and can be found at http://www.simple2ftp.com

Not sure but perhaps worth a try?
