WordPress返回所有文章元数据函数
WordPress函数get_post_custom用于获取指定文章的所有元数据,相当于使用get_post_meta()函数只指定文章ID而不带另两个参数的结果。
get_post_custom($post_id)
函数参数
$post_id
整数,默认值:当前文章ID
文章的ID
函数返回值
文章的自定义字段不同,返回的结果也有所不同:
Array
(
[_edit_last] => Array
(
[0] => 1
)
[_thumbnail_id] => Array
(
[0] => 242
)
[_edit_lock] => Array
(
[0] => 1618797471:1
)
[views] => Array
(
[0] => 123
)
[_wp_page_template] => Array
(
[0] => default
)
[_encloseme] => Array
(
[0] => 1
)
)
函数使用示例
$custom_fields = get_post_custom(72);
$my_custom_field = $custom_fields['my_custom_field'];
foreach ( $my_custom_field as $key => $value ) {
echo $key . " => " . $value . "<br />";
}
