i found nothing about it in the WP reference and Google, so i ask you: I want to update a post by a form - and with it its children.
$post = array(
'ID' => $mainid,
'post_status' => 'wartend'
);
$lead = wp_update_post($post);
$children = get_children( $mainid );
foreach ($children as $child){
wp_update_post(
array(
'ID' => $child,
'post_status' => 'wartend',
'post_parent' => $mainid
)
);
}
The post is getting updated, but not the children.

Reset to default 0get_children returns an array of post objects by default:
https://developer.wordpress/reference/functions/get_children/
So you would have to use 'ID' => $child->ID, in this case... also my want to wrap the foreach with if (count($children) > 0) {} to prevent possible errors where there are no children. ie:
$children = get_children( $mainid );
if (count($children) > 0) {
foreach ($children as $child){
wp_update_post(
array(
'ID' => $child->ID,
'post_status' => 'wartend',
'post_parent' => $mainid
)
);
}
}
}
