Hi,
What about using WFS describeFeatureType ?
http://localhost:8080/geoserver/wfs?request=DescribeFeatureType&typeName=topp:states
This
does not yield any output at all. At least not for my layers(I
deleted the demos).
As of now I get the layer as CSV and process it with PHP:
$url =
"localhost:8080/geoserver/wfs?request=getfeature&version=1.0.0&outputformat=csv&service=wfs&typename=workspace:Tan_regions";
//Send post request.
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_URL, $url);
$passwordStr = "user:pass";
curl_setopt($ch, CURLOPT_USERPWD, $passwordStr);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//Collect result.
$result = curl_exec($ch);
curl_close ($ch);
$parts = explode("\"",$result);
//break the string up at the "-character to get rid of the_geom
//grab the first part (one row of values remains at $parts['2'])
$prop_names = explode (",",$parts['0']);
This gives me a list of the given attributes but it seems to be a
major PITA to get the respective values for setting up presets, users
could choose whithout typing...
ahhhrrrmmmm... and I do not think, that this is the most neat of all
thinkable methods

Hello,
in order to allow users of my Gmaps-frontend to filter
Layers by
submitting CQL-statements I would like to get a list of
attributes
like this:
&cql_filter=(POPULATION > 1200000)
in
this case the given Layer contains the attribute POPULATION that
is
assigned to districts of a country. The filter allows, to select
shapes of such districts to be rendered if the POPULATION assigned
to
the district is greater than a number, the user may type in an
input-field.
That is straight forward, anyway I need to find out
the attribute
names (in this case POPULATION) to set up input boxes
that fit the
given layer. The attributes will become quite diverse
since we will
map water/sanitation installations that can be dozens of
different
things from a lake to a handpump. The handpump has a
throughput the
lake has a depth etc.
So I would need to query the
layer for its attributes. As of now I
copy the names from the wms-atom
preview in geoserver but of course,
that is no option in the long
run...
Is there any CQL-Magic or something similar to do that?
something like:
"request=ListAttributes&layers=workspacename:layername"
?
best regards
