Get parent page/menu id of current post

Question

Basically, after setting up the initial "page for post" on the Reading Options, and then add that page to the menu I get the posts when I click on that menu item as expected.

On there I know the post ID (which is the actual page created before setting it as the page for posts) and all the information regarding that same page.

Trouble is, when I click on a specific post, not only the menu item looses its active status, but I can't get hold of that parent page ID.

Is there a way to get that parent page ID, when on a post !?

Edit: For reference, I managed to get it with get_option('page_for_posts'); but that's very ugly. Is not possible that the post associates with it's parent page index ?

Answer 1

I believe you want get_queried_object. If you have set your static front page and blog page from wp-admin->Settings->Reading then get_queried_object will give you information about the page you chose rather than about the posts in the Loop.

Be aware that get_queried_object will return very different types of information depending on the kind of page you are on. From the Codex:

• if you're on a single post, it will return the post object
• if you're on a page, it will return the page object
• if you're on a category archive, it will return the category object

• etc.

On your posts page it should be a WP_Post object

$thispage = get_queried_object();
var_dump($thispage); // WP_Post object

Answer 2

How about global $post before the loop?
