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)
$post_id
整数,默认值:当前文章ID
文章的ID
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 ) )
$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 />"; }
get_post_custom()函数位于:wp-includes/post.php
相关函数:
get_the_ID()
get_post_meta()
get_post_custom_values()
get_post_custom_keys()
