I need an file uploading system that is similar to what you see on [url removed, login to view], [url removed, login to view], and [url removed, login to view] This system works with AJAX technology to give the progress of the uploading file(s). In my system, the backend should be in PHP/PERL. Also, it should allow for multiple file uploads similar to what is on [url removed, login to view] offers.
Another component must be added to this file uploading system as well. Before the files get uploaded, a check should be done to see whether the total number of bytes for the files selected does not exceed a predefined max upload size.
Lastly, this system must be extremely effecient and fast. The script must be Object Oriented and well documented. It must be optimized for fast loading and performance. It must be compatible with all browsers (IE 5+, Mozilla/Netscape/FireFox, Safari, Opera). It should not crash the browser and mostly importantly, it must give accurate data on the file upload progress.
Just to clarify, before the files get uploaded, a check should be done to see whether the total number of bytes for the files selected does not exceed a predefined max upload size. If it does that an error message is returned. If not, the files are uploaded.
When a file gets uploaded successfully, the server must make a record in a mysql 5 database of that file's name, location, type, size, and assign it a unique id. Once that's done the uploaded file is renamed to the unique id assigned in the database.
Another component must be created as well in addition to the AJAX file upload system, a Flash version must be created. Flash 8 supports multiple file uploading and showing the progress of the upload. This component is not difficult to create at all. In fact there is a great tutorial here: http://blog.oinam.com/archives/2005/08/flash-8-file-upload-download/.
