How to filter the FacetWP Google Maps options

This morning I was helping to work out some issues with a site using FacetWP and came across a useful filter contained within the Facet WP Google Maps addon.

Documentation for the Google Maps addon is a little sparse at the moment, so I thought it would be helpful to highlight the facetwp_map_init_args filter, which allows you to update the default Google Map options.

In this case we wanted to disable the scrollwheel zoom, so added the following code to functions.php.

	<?php

	add_filter( 'facetwp_map_init_args', 'prefix_prevent_scroll_zoom_on_facet_map' );
	/**
	* Filter the Google Map options to prevent scrollwheel zoom.
	* @link https://craigsimpson.scot/filter-facetwp-google-map-options
	*
	* @param array $args Array of init settings for Google map.
	*
	* @return array $args Modified array.
	*/
	function prefix_prevent_scroll_zoom_on_facet_map( $args ) {
	$args['init']['scrollwheel'] = false;
	return $args;
	}

Other Google Maps options can be set using the filter, such as preventing the map being draggable or removing the default map controls.
