Submitting a form to URL opens new window

If the PHP script doesn't return anything then how would Acrobat know the submit was successful? All HTTP operations have two sides, a Request and a Response. The Request is sent by the client, in this case Acrobat. The request is recieved by the server script, which process the request data and then sends a response. By default, PHP always sends an HTML response. Even if your PHP script does nothing, the PHP engine sends some token HTML code back. That's just the way it works.

When Acrobat recieves HTML back from a submit it thinks the server is sending an info page, possibly something useful about the submit, so it opens a browser window.

But the proper way for sever script to handle a request from Acrobat is to return Acrobat data. What I usually do is to return a simple FDF block containing a script which displays a popup message letting the user know the status of the submit. It Acrobat does not recieve anything back it assumes there was an error. So you must return somthing from the server.

Used FDF in example 1.3

Make sure you send the FDF content type first
http://us3.php.net/manual/en/function.fdf-set-on-import-javascript.php

header('Content-type: application/vnd.fdf');


Also if you send the FDF content type w/ no FDF attached it won't popup a new window..
