Learn how to use the Cron API, which enables you to perform time-based tasks at recurring intervals. Using WP-Cron in plugins enables you to emulate UNIX cron functionality, so you can do things like check schedules, update content, and modify existing data at regular intervals.
- [Instructor] In this video,…we learned how to use the cron API,…also referred to as WP-Cron.…WP-Cron enables us to perform time-based tasks…at recurring intervals.…This is useful for things like working…with temporary data, checking for updated content,…publishing scheduled posts, and so forth.…WP-Cron is a pseudo cron service.…Instead of running constantly like Unix cron,…WP-Cron runs only on page load.…So, when a page is loaded, WP-Cron checks the queue…of scheduled tasks and runs anything…that is past the scheduled time.…
In most cases, this pseudo approach works well,…but for sites with little activity,…the queue of scheduled events can build up.…The other big difference between Unix cron…and WordPress cron is how events are scheduled.…With real system cron, events are run…at specific times like 3:16 every morning.…With WP-Cron, events are run at specified intervals…like every day, hour, or minute.…WordPress provides three default intervals…for WP-Cron: hourly, every 12 hours, and every 24 hours.…
It's also possible to define our own custom intervals.…
