Get distance value for each post

[ciarlystreet]

Hi, this plugin is amazing! It's possible know the distance value for each post obtained from geo query?

Hi @ciarlystreet! If you sort by distance, elasticsearch returns the actual distance value as the sort value on each result. Then you can use an elasticpress hook to pull that into your post object, something like:

add_filter( 'ep_retrieve_the_post', function ( $post, $hit ) {
	$post['geo_distance'] = $hit['sort'][0];
	return $post;
}, 10, 2 );

Wanted to leave a quick follow-up here... you actually need to implement the hook mentioned above, PLUS an additional hook to allow elasticpress to set this value on your post object:

add_filter( 'ep_search_post_return_args', function ( $post_return_args ) {
	$post_return_args[] = 'geo_distance';

	return $post_return_args;
} );

Then you will be able to access this property on your post object in the loop:

global $post;

echo $post->geo_distance;
