我相信这不是最好的答案，不过你可以这样尝试
add_action(\'save_post\', \'add_my_taxonomy\');
function add_my_taxonomy($post_ID) {
$area = array(
\'ny\' => \'New York\',
\'la\' => \'Los Angeles\'
);
$zip = array(
\'ny\' => \'10001, 10002, 10003, 10004, 10005, 10006, 10007, 10008, 10009, 10010, 10011, 10012, 10013, 10014, 10015, 10016, 10017, 10018, 10019, 10020, 10021, 10022, 10023, 10024, 10025, 10026, 10027, 10028, 10029, 10030, 10031, 10032, 10033, 10034, 10035, 10036, 10037, 10038, 10039, 10040, 10041, 10043, 10044, 10045, 10046, 10047, 10048, 10055, 10060, 10069, 10072, 10079, 10080, 10081, 10082, 10087, 10090, 10094, 10095, 10096, 10098, 10099, 10101, 10102, 10103, 10104, 10105, 10106, 10107, 10108, 10109, 10110, 10111, 10112, 10113, 10114, 10115, 10116, 10117, 10118, 10119, 10120, 10121, 10122, 10123, 10124, 10125, 10126, 10128, 10129, 10130, 10131, 10132, 10133, 10138, 10149, 10150, 10151, 10152, 10153, 10154, 10155, 10156, 10157, 10158, 10159, 10160, 10161, 10162, 10163, 10164, 10165, 10166, 10167, 10168, 10169, 10170, 10171, 10172, 10173, 10174, 10175, 10176, 10177, 10178, 10179, 10184, 10185, 10196, 10197, 10199, 10203, 10211, 10212, 10213, 10242, 10249, 10256, 10257, 10258, 10259, 10260, 10261, 10265, 10268, 10269, 10270, 10271, 10272, 10273, 10274, 10275, 10276, 10277, 10278, 10279, 10280, 10281, 10282, 10285, 10286, 10292\',

foreach ($zip as $code => $zipcodes){

我从这里得到了Zipcode列表
