For those who stumble upon this later, use either option 1 or 2 found here: https://core.trac.wordpress.org/ticket/19373. “For other developers who run into this and need to work around it, either of these 2 options work: call wp_set_post_terms() to add your taxonomies after calling wp_insert_post() set up a “current user” in your script before calling wp_insert_post()”
According to the docs for this function, you can’t set up a weekly event by default. wp_schedule_event(int $timestamp, string $recurrence, string $hook, $args = array() ); The $recurrence value needs to be one of: “hourly” “twicedaily” “daily” You’ll need to test today’s date inside your callback function, my_event. Something like: function my_event() { # date(‘l’) … Read more
You can use real cron to trigger WP cron – by fetching wp-cron.php file from root (snippet from quick google search). That will take care of environment and everything.
As you’ve noted, cron jobs are only fired when someone visits your website. WordPress checks if they are any events that have been scheduled before ‘now’ that have not yet occurred – and runs them. Importantly with events that are recur according to a regularly pattern (say hourly) – their occurrence is relative not absolute. … Read more
This is only a partial answer. You can use Cron View to see what crons are still active on your blog. If you find some crons that shouldn’t be there then maybe my answer here will help you remove that cron: Cron jobs for deactivated plugins
No, the WP-Cron tasks run asynchronously from the viewing user. They should not see any delay. Although if your task takes more than a minute, it may never finish since most hosts are setup to kill PHP processes after 30 seconds.
Whenever you do get_posts or WP_Query or anything like that, it’s important to remember that the code is actually getting all of the Posts at once, and loading them from the database into memory. If you run out of memory, then your process will simply die with an error. Attempting to get very large numbers … Read more
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 … Read more
It looks for me that you are adding this event only when there is no such event ‘send_email_alerts_hook’ scheduled yet. Try something like this and let me know if it workded. function shedule_email_alerts() { if ( !wp_next_scheduled( ‘send_email_alerts_hook’ ) ) { wp_schedule_event(time(), ‘daily’, ‘send_email_alerts_hook’); } else { wp_reschedule_event(time(), ‘daily’, ‘send_email_alerts_hook’); } } The thing is … Read more
Check out wp_cron and the cron_schedules filter. There are lots of good tutorials out there like this one from WPTuts or this one from Viper007Bond.
