根据Polylang's documentation orderby 参数仅接受 slug name id 有效值。在上面的代码中,您传递代码

尝试更改:

$languages = icl_get_languages('skip_missing=0&orderby=code');

为:

$languages = icl_get_languages('skip_missing=0&orderby=slug');

if($l['code'] != 'zh-hant') { echo substr($l['native_name'], 0, 2); } else { echo $l['native_name']; }

为:

if($l['slug'] != 'zh-hant') { echo substr($l['native_name'], 0, 2); } else { echo $l['native_name']; }
