Saving server side file to local machine with JS

Sorry, I should have been clearer.

When PHP finishes creating the file I need one of the JS alert
type windows to appear that says..

"Your file has completed, would you like to save it to your
machine?"

Like you get when you download a file.

If I knew the JS code to do this I perhaps could embed it in
the PHP at the end of the function that creates the file???

Is that clearer?

Thanks,
Skip

Not sure if you can save it directly.... From javascript!

What you could do is.

1. Make an asynchrome call to a php script on the server with javascript.

2. Once PHP is finished you can make it return a URL to the asynchrome
javascript call. This URl will point to the generated download file.

3. Then with javascript create a nice div with two buttons. One to
initiate the download and the other to cancel...
