Thank you George.
I am looking forward to your feedback 🙂

Thank you for the update.

You can do that by using the following code

$associated_gallery_id = get_post_meta( $post_id, '_mppc_associated_photo_gallery_id', true );

You should use the actual post id for fetching gallery id.

Thank you.

In order to update the gallery details, you can use the following function(s)

Updating gallery status(If you only need to update status)

mpp_update_gallery_status( $gallery, $status ); // $status can be any valid status e.g 'public', 'private' etc.

Or you can use

mpp_update_gallery( $args );

where $args can be

$args = array(
	'id'           => $gallery_id, // *Required
	'title'        => 'gallery title', // optional, if not given, keeps the current gallery title.
	'description'  => 'gallery description', //optional.
	'slug'         => 'gallery-unique-slug',
	'creator_id'   => $user_id,//who created this gallery.
	'order'        => 0, // menu order.
	'component_id' => $user_id,//optional. will keep current component if not given.
	'component'    => 'sitewide', // optional
	'status'       => 'public', //new status
	'type'         => 'photo', //new type?
);

Everything except the id is optional.

For example, Here is how we are updating the gallery description.

Hope that helps.
