OK,
I am well along here, able to connect, getting output from my test.php
script, however, my post data seems inaccessible to me. I am passing
the coordinates of a user entered line-string to my script via post,
(excerpted from WFS.js and wfs-t.html), and while the alert prior to
sending shows the correct value of "data", I was assuming that I would
be able to see that data in my $_POST variable in the php script.
However, a print_r($_POST) yields an empty array.
Anyone have an idea of what I am missing?
Thanks,
r.b.
code:
data = OpenLayers.Ajax.serializeXMLToString(data);
alert(data);
var responseObj = new OpenLayers.Ajax.Request(url,
{ method: 'post',
postBody: data,
onSuccess: function(transport) {
alert('Successful Connection');
},
onComplete: function(transport) {
alert(transport.responseText);
}
}
);

Ahh, I came across the following (after claiming it could not be done):
http://www.prototypejs.org/api/ajax/request
This has helped me. I was failing to specify an "onComplete" method, so
I was rushing to evaluate the response before it happened.

Subject: [OpenLayers-Users] returning text from simple ajax request
I am trying to do a simple request of data (just a dummy page as the
target for now), but I am missing some crucial understanding, as this is
not working for me. Any small guidance anyone could provide would be
helpful, I am very new to working with Ajax.
My goal at the time being is to simply initiate a request from a page,
and then alert the data returned by that page. I assumed that an Ajax
request would be the right way to go. I am initiating the request as
follows:
Var url = 'test.php'
var responseObj = new OpenLayers.Ajax.Request(url,
{ method: 'post',
postBody: data,
onComplete: success,
onFailure: failure
}
);
var responseData = responseObj.transport.responseText;
alert(responseData);
And the request IS being made, as verified by my httpd access log:
172.16.210.66 - - [30/Jul/2007:10:31:14 -0400] "POST /wms_maps/test.php
HTTP/1.1" 200 154
However, I can't seem to find the text that is generated by test.php in
my responseObj. I am attempting to access this text with the
"responseText" property of my responseObj, but am getting only a blank
(whereas the script itself returns several lines of text).
Sorry if this is a dumb question, I have not been able to nabble any
successful tutorials on this.
TIA,
r.b.
