Sf wfs spat
The sf_wfs_spat is the subform for displaying spatial data. It calls on layers as defined from a wfs server (active) and overlays them on a map already setup using the map_admin page.
The sf_wfs_spat requires the following additional fields:
- query_layers - this is an array of the layers to be queried. It contains a set of arrays (one for each layer) named with the name of layer as set on the WFS server configuration. Each layer array takes the following values:
- mod - the module that the layer is linked to
- geom - the geometry of the wfs layer. This should be set to either pt, pl or pgn.
- url - the URL of the wfs server.
- style_array - OPTIONAL - this is for manually setting the style of the wfs information. It is a named array constructed from the style options explained on this page - the key should be the property name and the value the desired value.
- wms_layers - layers from the mapserver/mapfiles/ark_wms.map to use in this subform
- op_buffer - the buffer in selected units around main item shape in subform
- op_placetypes - an array of numeric placetype_ids. This can be used instead of sf_place - to provide an asynchronous query of the places (which may improve page loading times if you have many places in your database). OPTIONAL
The wms_layers acts as the background data while the wfs_layers contains the layers to be zoomed to.
