Set page to draft on plugin deactivation

Question

Im working on a little plugin that when activated creates a theme page and then a function sets this page to published this is the code i have for published:

// function that creates the new ads page on plugin install // 
function mjj_create_page ()
{
// Create new page object
$ads_page = get_option('mjj_smart_ads_page');

$ads_new_page = array(
    'post_title' => 'Smart Ads',
    'post_content' => '',
    'post_status' => 'publish',
    'post_type' => 'page'  
 );   
// Insert the page into the database
$ads_page = wp_insert_post( $ads_new_page );
update_option('mjj_smart_ads_page', $ads_page);

// now lets give this new page a groovy template
$ads_page_data = get_page_by_title('Smart Ads');
$ads_page_id = $ads_page_data->ID;
update_post_meta($ads_page_id, '_wp_page_template','tpl-smart-ads.php');

}

dont know if its semanticaly wp perfect but it seems to work ok and does what i need, however now im trying to set a function that will on plugin deactivate set this created page to draft status so it doesnt show in the menu, but it just doesbt seem to want to play, heres what im working with:

// function that drafts smart ads page on plugin deactivate // 
function mjj_unpublish_page ()
{
$old_ads_page = get_option('mjj_old_smart_ads_page'); 

$ads_old_page = array(
    'post_title' => 'Smart Ads',
    'post_content' => '',
    'post_status' => 'draft',
    'post_type' => 'page'  
  );
     // Insert the page into the database
$old_ads_page = wp_update_post( $ads_old_page );
update_option('mjj_old_smart_ads_page', $old_ads_page); 
}

and below are my hooks

    // create the page to get the info for selling ads and posting ads
    register_activation_hook($file, array(&$this, 'mjj_create_page'));
    //while in this block i will also add the deactivate function to unpublish the created page
register_deactivation_hook($file, array(&$this, 'mjj_unpublish_page'));

as you can see im thinking that setting to draft will include the use of wp_update_post, but it dont seem to be working right when deactivating, im ending up with one Smart Ads page published and one in draft

Answer 1

I'm posting this as another solution for you and its based on the page id

/*
$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'] = $status;
    return wp_update_post($current_post);
}

So once you have this function you can use it with the page id of the page you created:

$ads_page = get_option('mjj_smart_ads_page');
$old_ads_page = change_post_status($ads_page,'draft');
update_option('mjj_old_smart_ads_page', $old_ads_page);
