我原以为这是术语meta，但这似乎不正确。

为了便于说明，我创建了一个名为“Test”的类别，其中有一个“Test”的slug。

我正在用以下内容更新其term\\u meta：

update_term_meta( 64, \'test_meta\', \'asdfasdf\' );

这与其他元键/值一起出现在termmeta表中：

get\\u term（64）返回以下内容：

WP_Term Object
(
    [term_id] => 64
    [name] => Test
    [slug] => test
    [term_group] => 0
    [term_taxonomy_id] => 64
    [taxonomy] => category
    [description] => 
    [parent] => 0
    [count] => 0
    [filter] => raw
    [meta] => Array
        (
        )

)

为什么是[meta] 空的

get_term_meta(64) 按预期返回：

Array
(
[headline] => Array
    (
        [0] => 
    )

[intro_text] => Array
    (
        [0] => 
    )

[display_title] => Array
    (
        [0] => 0
    )

[display_description] => Array
    (
        [0] => 0
    )

[doctitle] => Array
    (
        [0] => 
    )

[description] => Array
    (
        [0] => Meta desc
    )

[keywords] => Array
    (
        [0] => someMetaKeyword
    )

[layout] => Array
    (
        [0] => 
    )

[noindex] => Array
    (
        [0] => 0
    )

[nofollow] => Array
    (
        [0] => 0
    )

[noarchive] => Array
    (
        [0] => 0
    )

[test_meta] => Array
    (
        [0] => asdfasdf
    )

)

add_filter( \'get_term\', function( $term ){
    $term->meta = get_term_meta( $term->term_id ); // all metadata
    return $term;
} );
