Map Facet

This add-on generates a map to display geocoded results. It can also filter results by showing only results within the map bounds.


This add-on generates a Map facet type, which works just like any other facet type.

The Data Source should be a custom field containing a comma-separated latitude, longitude.

Common data sources:

    • If your posts are not geocoded, try the Address Geocoder plugin. If you go this route, then choose martygeocoderlatlng for the data source.
    • WP Job Manager plugin (integrated in Listify and Listable themes) – set the facet’s Data Source to geolocation_lat.
    • Advanced Custom Fields Pro has a Google Maps field type that provides geolocation. Be sure to choose your field name in the “Advanced Custom Fields” section of the data source dropdown in the facet settings.

Marker Content

Enter display code for the content that displays when a marker is selected. The following example outputs the title, link, and excerpt.

  <a href="<?php the_permalink(); ?>" title="<?php the_title_attribute(); ?>">
    <?php the_title(); ?>
<?php the_excerpt(); ?>

IMPORTANT: Unlike the template display code, the marker content should not contain if ( have_posts() ), while ( have_posts() ), or the_post()

Available Options

Name Description
Other data source Choose a longitude field if stored separately from the latitude
Map Design Choose a design/color scheme for the map
Marker clustering This option will group markers into clusters
Marker limit “Show all results” will show all markers that match the results, “Show current page results” will only display markers matching the results on the current page of paginated results
Map Size Width and height of map. Use unitless for px, ex. 300, or with %, ex. 100%
Zoom Set the zoom bounds between 1 (minimum zoom) and 20 (maximum zoom)
Default Coordinates Centers map to this latitude and longitude when there are no results on the map

Using a Google Maps API Key

The map facet requires a valid Google Maps API key. After generating an API key, add it to Settings > Facet > Settings. Both the proximity facet and map facet will use this key.

Customizing the marker pins

add_filter( 'facetwp_map_marker_args', function( $args, $post_id ) {
    $args['icon'] = 'https://URL/TO/marker.png';
    return $args;
}, 10, 2 );

For more flexibility, you could alternatively use arrays to mimic Google’s JS objects:

add_filter( 'facetwp_map_marker_args', function( $args, $post_id ) {
    $args['icon'] = array(
        'url' => 'https://URL/TO/YOUR/marker.png',
        'scaledSize' => array(
            'width' => 16,
            'height' => 16
    return $args;
}, 10, 2 );
