I am displaying "Save-As dialogue box" using "header()" function.

 

How to know user has clicked "Save" or "Cancel" button in "Save-As dialogue box"?

This is a client side action, You php code has already processed the request at this point and sent to client browser. So now you cannot determine what button user pressed.

Thanx for ur reply....

 

Actually I am sending a download notification mail to the user who is downloading a file.

 

So, I should not send any mail if the user have not received the file completely. (like incomplete download, hitting "cancel" button...)

 

Is there any other way to achieve this download delivery confirmation?
