Simply check if the event is scheduled, and if not, schedule it: add_action( ‘init’, function () { if ( ! wp_next_scheduled( ‘my_scheduled_event’ ) ) { wp_schedule_event( time(), ‘hourly’, ‘my_scheduled_event’ ); } } );
So yeah, it does give errors for trying to unschedule something that isn’t scheduled, but the answer is pretty easy and simple: $timestamp = wp_next_scheduled( ‘scheduled_hook’ ); if ($timestamp) wp_unschedule_event( $timestamp, ‘scheduled_hook’ ); Since wp_next_scheduled will return false for unscheduled hooks, a simple if in front of the call to wp_unschedule_event will prevent it from … Read more
No, not quite. When you say this: wp_schedule_single_event( $sent_on, ‘my_custom_cron’, [ $notif_id, $notif_name, $membership_id, $lesson_id ] ); You are essentially saying is when the current time passes $sent_on, do: do_action( ‘my_custom_cron’, [ $notif_id, $notif_name, $membership_id, $lesson_id ] ); Cron jobs are just a TODO note to fire an action with some arguments in the future. … Read more
page load is not affected […] and the //METADATA is echoed/displayed immediately? With your current setup, that is not possible. In order to display immediately, you need the data. To get the data, you need to wait. Possible solutions are: Fetch the data before (e.g. via Cron) and populate the DB with the info. -> … Read more
I assumed that the post function is simply not found so when the time comes for that function to run, nothing happens The second parameter for wp_schedule_single_event() is actually an event name, which is really a hook. So the event/hook could be named my_event, my_plugin_retry_post, etc., and if you want the post() method to be … Read more
strtotime( ‘midnight’ ) will give you midnight for today, which has already happened! You want midnight for tomorrow. e.g. date( ‘F jS H:i:s’, strtotime( ‘midnight’ ) ) on July 19th is July 19th 00:00:00 However, date( ‘F jS H:i:s’, strtotime( ‘tomorrow midnight’ ) ) would be July 20th 00:00:00 …which is what you want! So … Read more
You can pass arguments to the wp_schedule_single_event function: wp_schedule_single_event($newdate, “one_day_before_event”, array($post->ID)); Then if you do an add_action you can say how many arguments it will receive (in this case 1). add_action( ‘one_day_before_event’, ‘some_function’, 10, 1 ); Then in your function you can access the variable: function some_function($post_id) { // Do something with $post_id }
A simple and dynamic way to use WordPress cron would be to set up an action hook for your schedule then only add scheduled events as and when you need them. The events would call a generic function and pass in your specific custom post type details through $args – add_action(‘my_schedule_event’, ‘generic_function’); function set_schedule($post_id) { … Read more
I believe by default these folders are created by user interaction, however, it’s possible that a plugin may be calling a function to create these monthly upload folders. Note that using this function will create a subfolder in your Uploads folder corresponding to the queried month (or current month, if no $time argument is provided), … Read more
For what it’s worth, I found wp-cron processes running under the Processes section in WHM. I killed them and now all wp-cron behavior is back to normal and the emails have stopped.
