File output

[bill]

I am a relative AJAX neophyte and a complete newbe to prototype.

I have an application that successively loads a series of php pages into the same div without problem using Ajax.updater.
The last php script, instead of generating html, writes a file to the output in OpenOffice Writer format (with the appropriate headers) so instead of displaying the result I want it to do a file download.  (http://www.phpclasses.org/browse/package/5797.html)

Now we get to the place I am lost.

I presume that instead of Ajax.updater I want to do something else  (Ajax Request ?) but I am not sure how to do this.

I'm not sure if it's the right way to do, but I just do an http call
(just link to the url), and make sure that my PHP script returns the
appropiate headers for the browser to download the file rather than
open it inline...

I don't think you need ajax for this...

[Alex McAuley]

Ajax cannot process a file download in the same way it cannot process a file
upload...

You have to output the link and make the user click it

you would be exactly right.

and to protect from hot linking then check the http referrer or a session variable and if that fails then redirect to a landing page.

you want to investigate the following header info

//cache controlling

header("Cache-Control: public");

//force download

header("Content-Description: File Transfer");

//set filename

header("Content-Disposition: attachment; filename=export.csv");

there are others of course

I feel much better about not being able to do what I couldn't do.
I guess I will open the last script in a new window and go from there.
Thanks all.

Alex is always right, as far as I know.

Not always m8 but thanks for the confidence!!!!!!!!!

Hi,

No need to open a new window - if it starts downloading you'll be left
with an empty window ;)
Just do an HTTP call to the server and your original page will remain
in the window if you have the correct headers going out from your
PHP...

Would you be so kind as to expand your suggestion, perhaps with a line of code ?

Interestingly enough, when I do a window.open() and the script just does a download, the window does not actually open, just the download dialog.  No orphan window after that (in FireFox).
