[OpenLayers-Users] Save/Commit features using Protocol.WFS & php cURL Proxy

[Ryan Williams]

Hi all,
I did some more research on why save features using the OpenLayers WFS 
protocol was not working when I used a proxy file.
I worked with one of our web programmers here and we discovered the 
problem was in the proxy file that uses php-cURL to pass the REQUEST 
variables onto a Geoserver box.

The proxy file passed the contents of the REQUEST that OpenLayers sends 
out - BUT, the 'Request Payload' is not in those REQUEST variables. So 
we were only passing the url to Geoserver.
To pass the Request Payload onto our GeoServer using this proxy he 
changed the php-cURL code so that it sends the $GLOBALS['HTTP_RAW_DATA'] 
as the POST fields.
like this:
......
$raw_data = $GLOBALS['HTTP_RAW_POST_DATA'];
  curl_setopt($request, CURLOPT_POSTFIELDS, $raw_data);
......

Works great now!
