我正在寻找一种只显示包含所请求的所有自定义字段的POST结果的方法。不是一个或另一个。我一次只能使用一个数组获得结果。任何帮助都将不胜感激。

        $documents = array(
        \'post_type\' => \'documents\',
        \'meta_query\' => array(
            array(
                \'key\' => \'document-type\',
                \'value\' => \'manual\',
            ),
            array(
                \'key\' => \'document-status\',
                \'value\' => \'current\',
            )
        )
     );
        query_posts( $documents );
        get_template_part( \'loop\', \'documents\' );
        wp_reset_query();

         $documents = "
            SELECT wposts.*
            FROM $wpdb->posts wposts
            JOIN $wpdb->postmeta document-status ON
              ( wposts.ID = document-status.post_id AND
                document-status.meta_key = \'document-status\' )
            JOIN $wpdb->postmeta document-type ON 
              ( wposts.ID = document-type.post_id AND
                document-type.meta_key = \'document-type\' )
            WHERE document-status.meta_value = \'current\'
            AND document-type.meta_value = \'manual\'
            AND wposts.post_status = \'publish\'
            AND wposts.post_type = \'documents\'
            AND wposts.post_date < NOW()
            ORDER BY wposts.post_date DESC
            LIMIT 0 , 4
         "; 
         $documents = $wpdb->get_results($documents, OBJECT);
        query_posts( $documents );
        get_template_part( \'loop\', \'documents\' );
        wp_reset_query();
