WordPress:Function Reference/wp schedule event

描述

Schedules a hook which will be executed by the WordPress actions core on a specific interval, specified by you. The action will trigger when someone visits your WordPress site, if the scheduled time has passed. See the WordPress:Plugin API for a list of hooks.

确定WordPress actions core 在你规定的特别的时间间隔内执行hook的时间。如果预定的时间已经过去，有人访问你的站点的时候，action就会引发。请看看插件API上的hooks列表。

用法

%%% <?php wp_schedule_event(time(), 'hourly', 'my_schedule_hook'); ?> %%%

%%% <?php wp_schedule_event(time(), 'hourly', 'my_schedule_hook'); ?> %%%

例子

规定每隔一小时的操作

To schedule an hourly event in a plugin, call wp_schedule_event on activation (otherwise you will end up with a lot of scheduled events!): 在插件中规定每隔一小时的操作，调用激活的wp_schedule_event（否则，你需要结束许多预定的操作！）

register_activation_hook(__FILE__, 'my_activation');
add_action('my_hourly_event', 'do_this_hourly');

function my_activation() {
	wp_schedule_event(time(), 'hourly', 'my_hourly_event');
}

function do_this_hourly() {
	// do something every hour
}

register_activation_hook(__FILE__, 'my_activation');
add_action('my_hourly_event', 'do_this_hourly');
function my_activation() {
	wp_schedule_event(time(), 'hourly', 'my_hourly_event');
}
function do_this_hourly() {
	// do something every hour
}
