wp_get_schedules(): array[]
Retrieve supported event recurrence schedules.
Contents
Description
The default supported recurrences are ‘hourly’, ‘twicedaily’, ‘daily’, and ‘weekly’.
A plugin may add more by hooking into the ‘cron_schedules’ filter.
The filter accepts an array of arrays. The outer array has a key that is the name of the schedule, for example ‘monthly’. The value is an array with two keys, one is ‘interval’ and the other is ‘display’.
The ‘interval’ is a number in seconds of when the cron job should run.
So for ‘hourly’ the time is HOUR_IN_SECONDS
(60 60 or 3600). For ‘monthly’, the value would be MONTH_IN_SECONDS
(30 24 60 60 or 2592000).
The ‘display’ is the description. For the ‘monthly’ key, the ‘display’ would be __( 'Once Monthly' )
.
For your plugin, you will be passed an array. You can easily add your schedule by doing the following.
// Filter parameter variable name is 'array'.
$array['monthly'] = array(
'interval' => MONTH_IN_SECONDS,
'display' => __( 'Once Monthly' )
);
Return
array[]
