Get $post Object from another page

Question

This is a rather simple question, so I'll keep it short.

Update1: In this context {page-structure} means just that: page1/page1-1/page1-1-1/{...}.

Update2: For further clarification, I want to do about the same the ACF Post Object field is doing, except I want to do it dynamically based on the URL structure as explained below.

I'm making a custom multilingual site, with a dual page structure (with and without /en). Any page at mysite.com/en/{page-structure} are getting its locale changed to en_US and the content (ACF) is fetched from the corresponding page at mysite.com/{page-structure}. Based on the locale different content is displayed.

How can I on mysite.com/en/{page-structure} automatically get the $post Object from mysite.com/{page-structure} (i.e. without en/)?

(Currently I'm using ACF to fetch fields from the corresponding page by rewriting the field requests, but it I could change the $post Object on the fly, it would make everything a little simpler.)

Answer 1

This is how you can get the post object of a page with a matching path, minus the /en part:

$page_path = get_page_uri( get_queried_object_id() ); // en/page/child-page
$target_page_path = str_replace( 'en/', '', $page_path ); // page/child-page
$target_page = get_page_by_path( $target_page_path ); // WP_Post of target page.

Answer 2

If I understand correctly the question, the right answer would be to use url_to_postid function.

Then you can setup post id this way:

global $post; 
$post = get_post($post_id, OBJECT);
setup_postdata($post);

// your code

wp_reset_postdata();

Answer 3

Use the $global in before your $post

For example:

global $post;
echo $post->ID;
