How to update page status from publish to draft and draft to publish

Question

I am trying to figure out how to write the code that will allow me to do the following with pages of a WordPress blog.

I need to have something where I specify which page ID's I want to list (about 15 total) and then give the user the ability to select which ones will be published or which ones will be a draft. This will remove them from the menu and will also remove page from the site as well.

I found this statement

To change a post status, you get the post, change its status field, then call wp_update_post with the new post object

The closest existing plugin is http://wordpress.org/extend/plugins/wp-hide-pages/ except that this plugin uses wp-list-pages. And, it only hides them and does not actually move them from Publish to Draft.

Answer 1

A faster solution is:

$post = array( 'ID' => $post_id, 'post_status' => $status );
wp_update_post($post);

This way you don't have to get the post.

Answer 2

Here is a function that changes post status

/*
$post_id - The ID of the post you'd like to change.
$status -  The post status publish|pending|draft|private|static|object|attachment|inherit|future|trash.
*/
function change_post_status($post_id,$status){
    $current_post = get_post( $post_id, 'ARRAY_A' );
    $current_post['post_status'] = $status;
    wp_update_post($current_post);
}

simple call the function and pass the post id and the new status you want it to have for example:

change_post_status(12,'private');
