Okay.

What is not programming?

I apologize, I left that first var xhr there in error because I was
trying to figure out how to get var $response back to
the display page from the print_test.php page. How do I go about
that or does that have to be another XMLHTTPrequest ? Maybe that is a
question for the php usenet group?
So I get a respose from the FTP printer, which says FTP connected or
FTP failed, that is a var fromthe printer_test.php page. It would be
great if I could get that response and display it to the user in the
<div> id="printer_response" <div>.

Here is the function
function printFromHere(){

var response ;

if ( window.XMLHttpRequest ) {// code for IE7+,
Firefox, Chrome, Opera, Safari
xhr=new XMLHttpRequest();
}else{ // code for IE6, IE5
xhr=new ActiveXObject("Microsoft.XMLHTTP");
}
xhr.onreadystatechange = function()
{
if(xhr.readyState == 4)
{
if(xhr.status == 200)

document.getElementById('printer_response').innerHTML="Received:" +
xhr.responseText;
else
document.getElementById('printer_response').innerHTML
="Error code " + xhr.status;
}
}
xhr.open(GET, "print_test.php", true);
xhr.send(null);
}


This is the submit button in the form,

<input type="submit" name="print" value="Print labels on this page"
onsubmit="printFromHere();"/></form></body>
</html>
Rgds,
Janis

P.S. I don't need to exchange any GET or POST data in this case with
the print_test.php page. I only need to print the labels on this page.
The data is written to a template text file. That file is FTP'd to a
zebra printer when the print_test.php page is called. I would like
some information on the handshake.
The AJAX just allows the user to click the button for all the pages
from the display page and not have to keep clicking the back button
from the print_test.php page.
There are pages and pages of labels. So what I really want to do is
to call the print_test.php that FTPs the template text file from
the display page. If I get a status 200 that should let me know the
page got called but I really need the $response var from that page to
be passed back to the display page. Right now what is happening when
I click the button is it eliminates the current data displayed and
only gives me the empty form?

Is "onsubmit" a valid event for an object of type submit? I thought it
was a form event.

I'm not sure whether you want to submit data from this form to the php
page that triggers the print operation or not. Clarification of that
might help. If you do, then to use an ajax request, you will have to use
javascript to assemble a full post or get request from the form data
when the button is clicked. It may be better to use a traditional form
submit and generate a new page with the printer response message on the
server.

If the data is already on the server, you don't need to use a form for
this, although how does the server know which data to use? Session
cookies? Job id from the form (which you might need to append to the get
request using ?field=value)? In either case, you probably shouldn't be
triggering ajax requests from a form's submit button using an onsubmit
handler.

You could use the form's onsubmit handler to specify javascript to
execute when the submit button is pressed. Perhaps that's what you want
to do? If you do that, and don't want to execute the form's action, make
sure your javascript returns false.

Your submit button is probably trying to call it's parent form's action,
unless your "onsubmit='blah'" is confusing it completely.

Perhaps you should use a normal button (rather than a submit) and give
it a value of, for example, "Send to Printer" and, perhaps, use an
appropriate event handler to call the javascript code.

If I had a better understanding of what you were attempting, I might be
able to give better and / or less confusing pointers to possible solutions.

The following javascript and html, if you understand what it shows,
might be useful to you, or it might not. If you don't understand it, but
instead just blindly copy parts, or all, of it, and things still don't
work, well you obviously didn't take the time to try and understand it
first!

<script type="text/javascript">
function clanger() {
// visit the soupdragon
var soupdragon;
if (window.XMLHttpRequest) { // ie7+ etc
soupdragon=new XMLHttpRequest();
}else{ // IE6, IE5
soupdragon=new ActiveXObject("Microsoft.XMLHTTP");
}
soupdragon.onreadystatechange = function()
{
if(soupdragon.readyState == 4)
{
if(soupdragon.status == 200)
document.getElementById('printer_response').innerHTML=
"Received: " + soupdragon.responseText;
else
document.getElementById('printer_response').innerHTML=
"Error code: " + soupdragon.status;
}
}
soupdragon.open(GET, "print_test.php", true);
soupdragon.send();
return false;
}
</script>

<form action="blah" method="whatever" onsubmit="clanger()">
...... fields .....
<input type="submit">
</form>

Filemaker is not a programming language. I feel like the statements
he is making about me are false.
