HOW TO: Submit a form to PHP with no return?
I need to submit a form for file upload to a PHP script but do not want
anything returned.
That is the TARGET for the form should be like a null device.
I am using a JavaScript function to submit the form.
Is there a way to do this?

<form method="post" action="null.php">
<!-- ... -->
and
<?php // null.php
// deal with file upload
// *with no* output to the browser
// and then ...
// ...
// ...
exit(0);
?>
What is this for?

Pedro Graca,
Thanks for a quick reply.
However, it does not seem to work.
The target defaults to self and the browser window simply goes blank.
Here is what I get back:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML><HEAD>
<META http-equiv=Content-Type content="text/html;
charset=windows-1252"></HEAD>
<BODY></BODY></HTML>
It is for a simple upload page without feedback.
....but I can not make it quiet.

I see.
Try this:
<?php
// deal with upload
header('Content-Type: text/plain; charset=us-ascii');
echo '';
?>

Why?
Why no feedback?
Not even a simple
Thank you for uploading the file whatever.zip
Now close your browser and go read a book :-)

Pedro Graca,
That will send me back a blank page.
Why?
I have a one page site that should not be reloaded due to possible user
rearrangement.
I do not want a popup nor internal iFrame.
So I would like the server to simply not respond or redirect any 'required'
output to a null device or non-existing window.
The file checks and user feed back come from elsewhere.

gsb, when someone uses a form such as for the purposes of obloading,
that form sends a request to the web server containing the uploaded data.
Because HTTP is a request/response protocol, your browser will "allways"
wait for and act on a response that the server will inevitably
provide (if nothing breaks).
Hence, you always have to put whatever you want to come next in a page
pointed to by the form action attribute.
If you don't want the screen to change, then point the action attribute
to the same file containing the form we are talking about.
A nice trick would be to use the onSubmit javascript event attribute in
the form element to pop up a new window which is also then specified in
the target element of the form attribute. The action attribute in the
form element can then point to a handling script which doesn't output
anything other than
<html><head/><body onload="document.close();" /></html>

Yes, that is what I thought you wanted.

Ah! Maybe your real problem is the "Back/Refresh" one :)
If that is it, I do like something like this:
1. Server sends the form to the browser (GET form.php)
2. User fills the form and submits (POST dealform.php)
3. Server deals with data and redirectes (header('Location: tak.php');)
4. User sees the "Thank you" page (GET tak.php)
If the user now presses Refresh he will be refreshing the GET, not the
POST; and if he presses Back he will be taken to 1. (again the GET and
not the POST)

Well, thank you both.
I now know more than before.
I had hoped for some PHP environment setting that would defeat the "HTTP
request/response protocol" and not send anything back.
So, I will use an internal, dynamically created iFrame and return the very
same page (I only have one page) with an onLoad check like:
<BODY onLoad="if(parent!=self)document.close();">
That will insure that the browser's refresh and back methods will redirect
to itself. Page components are already cached so I expect minimal impact on
performance.
Again, thanks for your time and help.
If you think of anything else, please post: I'll be glad to look.

website, would show a "request timed out"?
Adriaan.
In a Javascript newsgroup, Matt Kruse led me to this:
If you haven't used, HTTP Response 204 can be very convenient. 204 tells the
server to immediately termiante this request. This is helpful if you want a
javascript (or similar) client-side function to execute a server-side
function without refreshing or changing the current webpage. Great for
updating database, setting global variables, etc.
header("status: 204"); (or the other call)
header("HTTP/1.0 204 No Response");
Thought that y'all might like to know.

FWIW, in a similar discussions Chung Leong was suggested to post the
form to a invisible IFRAME.

Ok :-)

Adriaan,
By that point, the file contents are already on the server and stowed away.
Send me an email if interested and I'll send you a link of the example.

R. Rajesh Jeba Anbiah,
Returning the results to an invisible iFrame causes the Refresh and back
buttons of the browser (most) to screw up if pressed.
I did not like this option when I tried.

I just thaught of a way somehow like:
- submit the form as usual to $_SERVER['PHP_SELF']
- process form data
- send header("Location: ".$_SERVER['PHP_SELF']."?submitted=yes");
- Include that to the body tag: <?php if(isset($_GET['submitted'])) echo '
onLoad="history.back()"'; ?>
So you get back to where you want.

Knowing whether to change the Subject line is sometimes tricky, but,
if done, it ought to be done sensibly. I've changed this article's

Indeed.

That's sound advice as well. But the fact remains that

You forgot to read <news:news.newusers.questions>, didn't you? I urge
