How to clear the cache for a selected number of pages regularly

Question

Rather than dumping the entire site’s cache regularly, how can I schedule for the cache to clear the cache for only specific pages?

Answer

You can do this using the built-in Staq Cron Manager for clearing cache by page ID.

• Go to your site in the Staq Panel and click Cron Manager and click Add:

Select how often you want the job to run using the Job interval.

In the command field, enter:

wp wpstaq clear-cache --post_id=PAGE_ID

Replace PAGE_ID with the ID of the page you want to clear the cache for.

If you are not sure what the page ID is:

• Open the page in WordPress.
• Click Edit.
• Look at the URL in your browser and copy the numeric ID from the address bar:

This is how a completed cron job looks once the command and interval are set:

Click Save to activate the job.

You can create multiple cron jobs if you need to regularly clear the cache for more than one page.
