[OpenLayers-Users] writing to my own wfs server

[Burgholzer,Robert]

Arnd,
Thanks much for your response.  I am endeavoring to do what you suggest, although using PHP's native PostgreSQL connectors instead of ODBC.  

Currently, I am using the wfs-t.html scripts as my basis, and passing in the result of "OpenLayers.Ajax.serializeXMLToString(data);" to get the edited features into a form I can work with.  Having done that, I realize I now have to contend with parsing this GML, and am wading through that.
I would be interested in any code that you have put together that can handle the conversion from GML to WKT (if that is in fact what you are doing).  

Regards,
r.b.

Hello Robert,

I would think, you can talk to your postgis-db via odbc. 

I use the editing functions of openlayers to draw a feature, select that
feature and use a serverside asp-script to insert the selected feature as
WKT string via odbc into an access-db. With mapserver and ogr I can request
the geometry and attributes from the access-db and show it in the map.

It is also possible with a WMS GetFeatureRequest to select features from the
db and delete the features in the db with odbc.

When the great editing tools from openlayers get the possibility to update
features (changing the geometry after drawing it), one can use an internet
explorer and openlayers for drawing, updating and deleting geometry data.

Mit freundlichen Grüssen

I am thinking perhaps to post the data from the openlayers, and intercept it
with some php, that can then enter it into postgis via WKT (assuming that
the openlayers wfs-t object produces point cords for the shapes, which I
haven't verified, but assume that it must).

I will look at the packages to see further.

If you mean something that allows you to talk to PostGIS directly from a web
browser... I can't imagine how that would work. You're going to need some
kind of layer inbetween that speaks a non-binary language. 

FeatureServer is a Python CGI that is designed to speak a variety of
languages on the input side and output side, and is designed to be as little
work as possible to install. However, it requires some level of
configuration, and it is likely, or even possible, that you would be better
off with GeoServer.
