Introduction

Just like WordPress, some Geo Mashup data can be altered using filters. This is in the experimental phase in Geo Mashup 1.3, but hopefully will stabilize and grow.

Filters

geo_mashup_locations_json_object

Allows you to change the object data that gets sent to a map. Called once for each object.

Arguments:

• $json_properties - an associative array of properties to include in the object, including object_id, lat, lng, title, author, categories
• $queried_object - the query result row returned for the object

Example

Use the saved name instead of the default object title (post_title for posts).

function my_geo_mashup_locations_json_filter( $json_properties, $queried_object ) {
	$json_properties['title'] = $queried_object->saved_name;
	return $json_properties;
}
add_filter( 'geo_mashup_locations_json_object', 'my_geo_mashup_locations_json_filter', 10, 2 );

Now you can access the data in custom javascript:

GeoMashup.addAction( 'objectIcon', function( properties, object ) {
	// Use a special icon for the saved location 'Swimming Pool'
	if ( 'Swimming Pool' == object.title ) {
		object.icon.image = properties.template_url_path + 'images/pool_icon.png';
	}
} );

geo_mashup_locations_fields

Modify the fields included in a map query.

geo_mashup_locations_join

Modify the tables joined in a map query.

geo_mashup_locations_where

Modify the where clause of a map query.

geo_mashup_locations_orderby

Modify the orderby clause of a map query.

geo_mashup_locations_limits

Modify the limit clause of a map query.
