Generate safer WP-Cron scheduling code
WordPress scheduled tasks are driven by hooks and intervals rather than a traditional system cron clock. This generator creates a practical PHP starting point for recurring or one-time WP-Cron events, including a duplicate-scheduling guard and optional custom recurrence.
What this generator creates
- A namespaced-style prefixed hook and callback.
- A
wp_next_scheduled()guard before recurring scheduling. wp_schedule_event()for recurring jobs orwp_schedule_single_event()for one-time jobs.- An optional
cron_schedulesfilter when you need an interval WordPress does not provide by default. - A deactivation cleanup example for recurring plugin jobs.
Default WordPress schedules
WordPress includes hourly, twice-daily, daily and weekly recurring schedules. Plugins can register additional intervals with the cron_schedules filter. A custom interval is measured in seconds.
Why the duplicate guard matters
Calling wp_schedule_event() repeatedly can create duplicate events. Before scheduling a recurring hook, check whether the same hook and arguments already have a next scheduled occurrence.
WP-Cron is not a precise system scheduler
A due WP-Cron event normally runs when WordPress receives traffic after its scheduled time. That makes WP-Cron useful for ordinary background maintenance, but it should not be treated as a guarantee that a callback executes at an exact second. For timing-sensitive or low-traffic sites, a real server scheduler can invoke WordPress cron instead.
How to use the generated code
- Choose recurring or one-time mode.
- Give the hook a unique, prefixed name.
- Select a built-in recurrence or create a custom interval.
- Generate the snippet and review every line.
- Place it in the plugin or controlled codebase that owns the task.
- Replace the placeholder callback body with the actual work.
- Verify the event exists and then verify the callback result, not just the schedule entry.
Important limitations
The generator cannot know whether your callback is safe, idempotent or efficient. Avoid long blocking work, uncontrolled remote requests and callbacks that can process the same record twice. Scheduling code is only one part of a reliable background-task design.
Frequently asked questions
Can WP-Cron run every five minutes?
Yes, but five minutes is not a built-in recurrence. Register a custom 300-second schedule first, then schedule the event using that recurrence key.
Should I schedule the event on every page load?
No. If scheduling logic can execute repeatedly, guard it with wp_next_scheduled() using the same hook and arguments.
What happens when a plugin is deactivated?
A plugin should clean up recurring events it owns. The generated recurring example includes a deactivation cleanup pattern.
Does a scheduled time mean WordPress runs it at exactly that time?
No. WP-Cron checks due events as WordPress runs, so execution can be later than the nominal due time.
