我想從使用array_column wp_get_post_terms提取term_ids數組,但它不會返回任何東西。WordPress的array_column不工作wp_get_post_terms
下面是代碼:
$atype = wp_get_post_terms($property_ID, 'property_category', true);
$types = array_column($atype, 'term_id'); // Not working so using array map
$types2 = array_map(function($te) {
return $te->term_id;
}, $atype);
echo '$atype: ';
echo '<pre>'; print_r($atype); echo '</pre>';
echo '$types: ';
echo '<pre>'; print_r($types); echo '</pre>';
echo '$types2: ';
echo '<pre>'; print_r($types2); echo '</pre>';
下面是結果:
$atype: Array
(
[0] => WP_Term Object
(
[term_id] => 51
[name] => Office
[slug] => office
[term_group] => 0
[term_taxonomy_id] => 51
[taxonomy] => property_category
[description] =>
[parent] => 0
[count] => 1
[filter] => raw
)
)
$types: Array
(
)
$types2: Array
(
[0] => 51
)
爲什麼不array_column工作?根據文檔,它應該。我正在使用> php 5.5。 http://php.net/manual/en/function.array-column.php
