I wrote a browser based application (yes it is an application!) (but I can't
let you see it cause it's propriatary technology) but the client side was
javascript and I had PHP save the data and read data...
I won't go into detail, but basically I had PHP print JavaScript, and then
have a variable in the main window that the child window would save the new
data to...
for example, have the javascript (which PHP generates) be something like
<script>
var DATAARY = new Array();
DATAARY[0] = 'Some data';
DATAARY[1] = 'Some data';
DATAARY[2] = 'Some data';
DATAARY[3] = 'Some data';
window.parent.document.MAINDATAARY = DATAARY;
</script>
It was something to that extent, it works quite nicely, and it definetly
pushes the limits of the technology used.

Subject: Re: [PHP] Invoke PHP script from onLoad handler?
OK, I've gone back through the archives and now understand the situation
with client- and server-side. I just wasn't thinking it through.
Spawning a window to let PHP query the db and somehow passing returned
values back to the parent window is something I could do, I suppose, but
it seems that what I and the other zillion people who keep asking the
same question need is a way to get to our databases using a client-side
technology like Javascript.
I recognize the shortcomings of client-side stuff like compatility
issues and on/off preferences and in this case am willing to let the
user take some reponsibility for his browsing experience.
Now I'm completely off-topic, but does anyone have any ideas regarding
database access with Javascript, perhaps by having JS run a shell or
perl script? How would JS get the values back? Something like
function getdb () {
var mylist = execute.some.remote.program(./getmysqldata.pl);
}
With all the traffic on this type of request, I'm surprised the FAQ
doesn't take
up the subject.
Thanks,
Chuck

You *can* have a JavaScript handler invoke PHP -- but it requires
accessing
a URL and waiting for the web-server to respond, so your response time
will
not be so hot.
I'm afraid I don't recall how, but it has been posted here before...
