很抱歉重新发布这篇文章，但它出现在头版，我注意到它太旧了，太晚了。。。以下是我对这个问题的看法：

// This will filter the shortcode attributes and will insert custom 
// value for the "cat" parameter
function filter_gmaps_shortcode_atts( $atts ) {
    // We add a custom value in the $cat parameter
    if ( is_tax( \'cities\' ) ) {
        $atts[\'cat\'] = \'filter_taxonomy_cities\';
    } elseif ( is_tax( \'regions\' ) ) {
        $atts[\'cat\'] = \'filter_taxonomy_regions\';
    }

    return $atts;
}
add_filter( \'gmshc_shortcode_atts\', \'filter_gmaps_shortcode_atts\', 10 );

// This filters the WordPress query and checks for our custom values from above
// We then modify the query to look for the proper post type and taxonomy
function filter_gmaps_get_post( &$wp_query ) {
    if ( isset( $wp_query->query_vars[\'category__in\'] ) ) {
        $queried_obj = get_queried_object();
        if ( in_array( \'filter_taxonomy_cities\', $wp_query->query_vars[\'category__in\'] ) || in_array( \'filter_taxonomy_regions\', $wp_query->query_vars[\'category__in\'] ) ) {
            unset( $wp_query->query_vars[\'category__in\'] );

            $wp_query->query_vars[\'tax_query\'] = array(
                array(
                    \'taxonomy\' => $queried_obj->taxonomy,
                    \'terms\' => array( intval( $queried_obj->term_id ) ),
                    \'field\' => \'id\'
                )
            );
            $wp_query->query_vars[\'post_type\'] = \'hotels\';
        }
    }
}
add_action( \'pre_get_posts\', \'filter_gmaps_get_post\', 10 );

只需遵循此链接，它将引导您完成向自定义分类添加自定义字段的过程。从这一点上，您可以在创建的新元框中添加html代码，并在其中插入您的google地图代码。然后获取两个点x，y并将其插入两个文本输入中，并存储它们以用于自定义分类。http://pippinsplugins.com/adding-custom-meta-fields-to-taxonomies/

另一个将谷歌地图添加到自定义帖子类型的链接。http://www.billerickson.net/integrate-google-maps-wordpress/谢谢
