Map on a taxonomy archive

Show a map on category / tag / custom taxonomy archives that automatically filters to the current term.

Steps

  1. Create a map whose main post type matches the archive.
  2. Embed it in the taxonomy template:
echo do_shortcode( '[cspm_main_map id="65"]' );
  1. Add this to your child theme functions.php:
/**
 * Filter Progress Map by the current taxonomy term on archives.
 */
function cspm_update_taxonomy_map_settings( $map_settings, $map_id ) {

	if ( ! class_exists( 'CspmMainMap' ) ) {
		return $map_settings;
	}

	$CspmMainMap  = CspmMainMap::this();
	$fields_prefix = $CspmMainMap->metafield_prefix;

	if ( is_tax() || is_category() || is_tag() || is_archive() ) {

		$queried_object = get_queried_object();

		if ( empty( $queried_object->taxonomy ) || empty( $queried_object->term_id ) ) {
			return $map_settings;
		}

		$taxonomy = $queried_object->taxonomy;
		$term_id  = (int) $queried_object->term_id;

		$map_settings[ $fields_prefix . '_taxonomie_' . $taxonomy ] = serialize( array( $term_id ) );
	}

	return $map_settings;
}
add_filter( 'cspm_map_settings', 'cspm_update_taxonomy_map_settings', 10, 2 );

Tips

  • Restrict the filter to one map: if ( (string) $map_id !== '65' ) return $map_settings;
  • Ensure posts on that archive actually have coordinates.
  • For more complex overrides (meta, include/exclude), see Override map query.
