Recurring scheduled task help

You have to schedule your event in a hook, for example in after_setup_theme or wp actions: add_filter(‘cron_schedules’,’my_cron_definer’); function my_cron_definer($schedules){ $schedules[‘twomin’] = array( ‘interval’=> 120, ‘display’=> __(‘Once Every 2 Minutes’) ); return $schedules; } add_action(‘my_periodic_action’,’my_periodic_function’); function my_periodic_function(){ mail(’[email protected]’,’Test!’, ‘Test Message’); } add_action( ‘wp’, ‘wpse8170_setup_events’ ); // or add_action( ‘after_setup_theme’, ‘wpse8170_setup_events’ ); function wpse8170_setup_events() { if ( … Read more

crontab wp-cron.php on multisite path-based network: one for each path? Or just one for the root?

For Q1 – One for each path / site. Each site has its own cron (jobs) internally. So, it is possible to fine-tune the frequency. For example, a low-traffic site may not have lots of cron jobs. So, the cron could be executed less frequently than a site that requires frequent updates. For Q2 – … Read more

run a cron task without obstructing page load?

Cron tasks don’t directly affect page load besides the 0.01s timeout (of course, they do affect server load, so they can impact page load indirectly). My hunch is that your PHP config is the issue. The cron tasks run like any other web request, and they’re subject to PHP’s max_execution_time INI setting. If this is … Read more

Refresh external feeds only in cron?

My recommendation would be to set up a wrapper for fetch_feed(). Call the wrapper function through WordPress’ cron and you shouldn’t have an issue. So something like: function schedule_fetch_feeds() { if ( ! wp_next_scheduled( ‘cron_fetch’ ) ) { wp_schedule_event( time(), ‘hourly’, ‘cron_fetch’, ‘http://blog1.url/feed’ ); wp_schedule_event( time(), ‘hourly’, ‘cron_fetch’, ‘http://blog2.url/feed’ ); } } function fetch_feed_on_cron( $url … Read more

Need to execute a cron job

Your option using WP internals would be to use the HTTP API along with wp schedule event Create a scheduled event, something like: register_activation_hook(__FILE__, ‘my_schedule’); add_action(‘execute_my_url’, ‘do_this_daily’); function my_schedule() { $timestamp = //some time you want it to run wp_schedule_event($timestamp, ‘daily’, ‘execute_my_url’); } function do_this_daily() { wp_remote_get( ‘../ =myvideoblog/mvb_main.php&action=processfeed&updatefeed=67’, $args); } This is a simple … Read more

wp_schedule_event not working?

Turns out I had to set the ALTERNATE_WP_CRON flag in wp-config.php to make this work: define(‘ALTERNATE_WP_CRON’, true);

Running WP Cron on specific local time

Not sure what is the question, but the use of time() is wrong as it will give you at best the local time of the server and not the local time of the site which takes into consideration the time zone configuration of WordPress. The function that you should use is current_time.

Get frequency of scheduled event

This is an old question, but hopefully this helps someone facing the same issue. We can use wp_get_schedule( $hook ) to retrieve the cron schedule for the hook. Then we can use wp_get_schedules() to retrieve the supported cron recurrences. Find the correct array value and return it. /** * Retrieve Cron interval for hook. * … Read more

When does next Cron Job run (time from now)?

Edit: wp_next_scheduled() returns the timestamp of the next scheduled job of a specified wp-cron job-arguments pair. Please note that this differs slightly in functionality to the answer below, in that you have to provide the arguments passed to cron job’s callback (if it has any). The original answer would provide the time of the next … Read more

Better handling of WP-CRON server load abuse

This is the intended use of the WP_CRON_LOCK_TIMEOUT constant. When WordPress is loaded, it checks to see if a cron job is running (if cron is locked). If cron is not locked, it will try to create a lock – if the lock timeout has not been reached, no lock can be acquired and cron … Read more
