I have a function that hooks into save_post that changes the value of a custom taxonomy term based on today's date. That's working fine. When I update a post, the taxonomy term is updated correctly.

But I want this update to happen automatically, once a day, without having to manually update the posts myself. I read up on wp_cron and created the below code which is basically an attempt to, once a day, query for a certain set of posts and then simply run them through wp_update_post() which should trigger the function mentioned above that changes the term value of the taxonomy.

But it doesn't seem to be working. Also, I don't really know how to test wp_cron without just waiting for a day and seeing what happens. I have a console installed so I can see upcoming scheduled events, and the below event is definetely scheduled, it just doesn't seem to be having any effect.

Can anyone offer some advice on where I might have gone wrong?

    //Schedule active events to update_post every day
    if( !wp_next_scheduled( 'event_status_refresh' ) ) {  
       wp_schedule_event( time(), 'daily', 'event_status_refresh' );  
//When the event fires, we call the function to update the posts
    add_action( 'event_status_refresh', 'update_event_status' ); 

//The function to update the posts
function update_event_status() {
    global $post;

    $active = array( 
$query   = new WP_Query($active);
if ($query->have_posts()) {
    while ($query->have_posts()) {

            $update = array(
            'ID' => get_the_ID(),

            // Update the post into the database
            wp_update_post( $update );

This is a typical example of an X-Y problem. Your cron is fine. Your logic not so.

You have a function that hooks into save_posts and you think that passing the array $update = array( 'ID' => get_the_ID() ) will trigger the action and so your post will update the taxonomy. That's incorrect, unfortunately.

Passing this type of array (only the ID field) to wp_update_post will only identify the post, it has no data to save elsewhere in the array. So it won't update anything and won't trigger any save_post actions.

So your cron is running every day, but doing nothing.


The function that hooks into save_post probably accept a post_id as param and update post if needed, right. So, instead of running wp_update_post and letting it update the post, call your function by itself.

while ($query->have_posts()) {
  $toupdate = get_the_ID();

  your_function_that_hook_into_save_post( $toupdate );
