CroNiX Posted August 24, 2010 Share Posted August 24, 2010 You asked how to get the size before the upload, and you can't because it isn't on the server yet and afaik, there is no javascript that will give you accurate results. You allow the upload, and then validate it once its on the server, including its size, and either accept the upload or reject it. There might be some flash upload script that can verify the size before upload, but you can't with php.

Alex Posted August 25, 2010 Share Posted August 25, 2010 I was assuming he meant before it's uploaded to a more permanent place on the server. Most of the time when talking about this kind of thing people don't consider a file in a temporary folder to be uploaded, although technically it is.
