    Hi there,

    Please allow me to ask this question. First of all my goal that im trying to achieve is deleting thousands of post after the import but the process should have to be in the background. meaning even if they close the website the deletion will continue until its finished.

    So my question is:
    If i manage to trigger the wp_cron which is i already did. will it end if all of the post needed to be deleted is already done? or will it repeat? because the wp_cron is being called at the end of the import to delete the posts.

    And does wp_cron the best way to run process in the background? or is there another wp method or function that can do process in the background even if the browser is already closed.

    This page may assist you with details:

    But to answer briefly, wp_cron runs on a page load on the site, so if you set everything up and then the site is closed and never visited again – the process will not complete. If you try to do too much the site will become slow and likely as not hit a server level timeout if you are trying to delete thousands of posts so ideally they should be done in batches.

    Deleting in manageable batches through wp_cron is a good way to accomplish the task. For the sake of throwing out alternative ideas, you could instead manually trigger a batch delete by sending a specific request through /wp-admin/admin-post.php. The time out limit can be increased to allow more posts to be deleted at once. You could manually trigger the process at a time when your server load is low. Repeat as needed until all unwanted posts are removed.

    Of course a wp_cron task can be scheduled in the same manner. I think admin-post.php tasks are easier to set up than wp_cron. It’s similar to WP Ajax except no JavaScript is used. It’s less likely to adversely affect other users. Wp_cron can affect other users by its very nature.
