Draft standard post by ACF Data picker

This code works perfectly!

function delete_expired_posts() {
$args = array(
    'post_type' => 'post',
    'meta_query' => array(
        array(
            'key' => 'fecha_borrado', 
            'compare' => 'EXISTS',
        ),
    ),
    'posts_per_page' => -1, 
);

$query = new WP_Query($args);

if ($query->have_posts()) {
    while ($query->have_posts()) {
        $query->the_post();
        $post_id = get_the_ID();

        $acf_date = get_field('fecha_borrado', $post_id); 
        $acf_timestamp = strtotime($acf_date);
        $current_timestamp = time();

        if ($acf_timestamp && $acf_timestamp < $current_timestamp) {
            wp_delete_post($post_id, true); // Permanently delete post
        }
    }
}

wp_reset_postdata();
}

if (!wp_next_scheduled('delete_expired_posts_daily')) {
wp_schedule_event(time(), 'hourly', 'delete_expired_posts_daily');
}
add_action('delete_expired_posts_daily', 'delete_expired_posts');
