如何扩展此函数来检查当前自定义帖子类型是否属于后代类别
我使用以下函数来检查查看的帖子是否属于给定 ID 的后代类别。
我如何扩展该函数以检查当前查看的“自定义帖子类型”是否属于给定 ID 的后代类别?
我使用此函数将菜单项设置为“活动”。
功能是:
/**
* Tests if any of a post's assigned categories are descendants of target categories
*
* @param int|array $cats The target categories. Integer ID or array of integer IDs
* @param int|object $_post The post. Omit to test the current post in the Loop or main query
* @return bool True if at least 1 of the post's categories is a descendant of any of the target categories
* @see get_term_by() You can get a category by name or slug, then pass ID to this function
* @uses get_term_children() Passes $cats
* @uses in_category() Passes $_post (can be empty)
* @version 2.7
* @link http://codex.wordpress.org/Function_Reference/in_category#Testing_if_a_post_is_in_a_descendant_category
*/
function post_is_in_descendant_category( $cats, $_post = null )
{
foreach ( (array) $cats as $cat ) {
// get_term_children() accepts integer ID only
$descendants = get_term_children( (int) $cat, 'category');
if ( $descendants && in_category( $descendants, $_post ) )
return true;
}
return false;
}
提前致谢!
I use the following function to check whether the viewed post is in a descendant category of the given ID.
How can i extend the function to also check if the current viewed "custom post type" is in a descendant category of the given ID?
I use this function to set a menu item to "active".
The function is:
/**
* Tests if any of a post's assigned categories are descendants of target categories
*
* @param int|array $cats The target categories. Integer ID or array of integer IDs
* @param int|object $_post The post. Omit to test the current post in the Loop or main query
* @return bool True if at least 1 of the post's categories is a descendant of any of the target categories
* @see get_term_by() You can get a category by name or slug, then pass ID to this function
* @uses get_term_children() Passes $cats
* @uses in_category() Passes $_post (can be empty)
* @version 2.7
* @link http://codex.wordpress.org/Function_Reference/in_category#Testing_if_a_post_is_in_a_descendant_category
*/
function post_is_in_descendant_category( $cats, $_post = null )
{
foreach ( (array) $cats as $cat ) {
// get_term_children() accepts integer ID only
$descendants = get_term_children( (int) $cat, 'category');
if ( $descendants && in_category( $descendants, $_post ) )
return true;
}
return false;
}
Thanks in advance!

这不适用于自定义帖子类型吗?你尝试过吗?
Doesn't this work with Custom Post Types? Have you tried?
