Description

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.

Additional Fields

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.

Example Configuration

// Spatial viewer (subform)
$conf_mcd_spat = 
    array(
        'view_state' => 'max',
        'edit_state' => 'edit',
        'sf_title' => 'spat_data', 
        'sf_html_id' => 'spat_display',
        'sf_nav_type' => 'name',
        'script' => 'php/subforms/sf_wfs_spat.php',
        'query_layers' =>
            array(
                'sites' =>
                    array(
                        'mod' => 'fst',
                        'geom' => 'pt',
                        'url' => 'http://ark.lparchaeology.com/ark/php/map/ark_wxs_server.php?',
                    	'style_array' => 
                            array(
                            'strokeColor' => '"black"',
                            'fillColor' => '"grey"',
                    	)
                ),
        ),
        'background_map' => 'Basic',
        'op_buffer' => 100,
);
