I would like to suggest this code using get_post_meta(). $my_custom_field = get_post_meta(get_the_ID(), ‘app_collection-postcode’, true); $my_custom_field2 = get_post_meta(get_the_ID(), ‘app_delivery-postcode’, true); $url = “http://maps.googleapis.com/maps/api/distancematrix/json?origins=$my_custom_field&destinations=$my_custom_field2&mode=driving&language=en-EN&sensor=false”; $data = @file_get_contents($url); $result = json_decode($data, true); foreach($result[‘rows’] … Read more
