带有进度条的jquery.form.js文件上传，服务器端php脚本中有什么内容？

Question

I am trying to set up file upload function as in http://jquery.malsup.com/form . But the example for file upload with progress bar do not have the server side script example.

All that i know is to process the $_FILES, $_POST, sanitise, and save; but not able to figure how to send progress bar data from server to browser. I am not sure how uploadProgress get data from file_echo2.php in the example http://www.malsup.com/jquery/form/progress2.html

Can some one hint me in how to capture the file upload progress while it is uploading? Thanks in advance.

Well there is nothing that needs to be done on the server side script ! On the client side javascript, hook a function to handle uploadProgress event. uploadProgress returns the values event, position, total, percent. make use of percent value to show a progress bar or any other way you want it behave.

I had particularly zeroed on this (among a wide variety of choices like plupload , uploadify etc) because it do not use any flash files. Now that i learnt that this needs no special server side script to handle is a huge plus point.

Many thanks to malsup and more details at jquery plugin
