Почему некоторые cron события не выполняются в соответствии с расписанием?

You can read all about cron events that miss their schedule on the WP Crontrol website.

Why do some cron events reappear shortly after I delete them?

If the event is added by a plugin then the plugin most likely rescheduled the event as soon as it saw that the event was missing. To get around this you can instead use the «Pause this hook» action which means it’ll remain in place but won’t perform any action when it runs.

Безопасно ли удалять cron события?

This depends entirely on the event. You can use your favourite search engine to search for the event name in order to find out which plugin it belongs to, and then decide whether or not to delete it.

If the event shows «None» as its action then it’s usually safe to delete. Please see the other FAQs for more information about events with no action.

Почему я не могу удалить некоторые cron события?

The WordPress core software uses cron events for some of its functionality and removing these events is not possible because WordPress would immediately reschedule them if you did delete them. For this reason, WP Crontrol doesn’t let you delete these persistent events from WordPress core in the first place.

If you don’t want these events to run, you can use the «Pause this hook» action instead.

Что происходит, когда я приостанавливаю событие?

Pausing an event will disable all actions attached to the event’s hook. The event itself will remain in place and will run according to its schedule, but all actions attached to its hook will be disabled. This renders the event inoperative but keeps it scheduled so as to remain fully compatible with events which would otherwise get automatically rescheduled when they’re missing.

As pausing an event actually pauses its hook, all events that use the same hook will be paused or resumed when pausing and resuming an event. This is much more useful and reliable than pausing individual events separately.

Что происходит, когда я возобновляю событие?

Resuming an event re-enables all actions attached to the event’s hook. All events that use the same hook will be resumed.

What does it mean when «None» is shown for the Action of a cron event?

This means the cron event is scheduled to run at the specified time but there is no corresponding functionality that will be triggered when the event runs, therefore the event is useless.

Зачем добавлять новые cron расписания?

Cron schedules are used by WordPress and plugins for scheduling events to be executed at regular intervals. Intervals must be provided by the WordPress core or a plugin in order to be used. As an example, many backup plugins provide support for periodic backups. In order to do a weekly backup, a weekly cron schedule must be entered into WP Crontrol first and then a backup plugin can take advantage of it as an interval.

Как создать новое cron событие?

There are two steps to getting a functioning cron event that executes regularly. The first step is telling WordPress about the hook. This is the part that WP Crontrol was created to provide. The second step is calling a function when your hook is executed.

Шаг первый: Добавление события

From the Tools → Cron Events menu, click on Add Cron Event. Fill out the details of the event. You’re best off using a hook name that conforms to normal PHP variable naming conventions. The schedule is how often the event will be executed. If you don’t see a good interval, then add one in the Settings → Cron Schedules menu.

Шаг второй: Написание функции

This part takes place in PHP code (for example, in the functions.php file from your theme). To execute your hook, WordPress runs an action. For this reason, we need to tell WordPress which function to execute when this action is run. The following line accomplishes that:

add_action( 'my_hookname', 'my_function' );

The next step is to write your function. Here’s a simple example:

function my_function() {
    wp_mail( 'hello@example.com', 'WP Crontrol', 'WP Crontrol rocks!' );
}

Как создать cron событие, которое запрашивает URL?

From the Tools → Cron Events menu, click on Add Cron Event. Select the «URL cron event» option, fill out the details, and press the «Add Event» button.

You can read all about the features and security of URL cron events on the WP Crontrol website.

Как создать новое PHP cron событие?

From the Tools → Cron Events menu, click on Add Cron Event. Select the «PHP cron event» option and enter the schedule and next run time. The event schedule is how often your event will be executed. If you don’t see a good interval, then add one in the Settings → Cron Schedules menu. In the «PHP Code» area, enter the PHP code that should be run when your cron event is executed. You don’t need to provide the PHP opening tag (<?php).

Creating, editing, and running PHP cron events is subject to restrictive security permissions. You can read all about the features and security of PHP cron events on the WP Crontrol website.

Какие пользователи могут управлять событиями и расписаниями cron?

Only users with the manage_options capability can manage cron events and schedules. By default, only Administrators have this capability.

Какие пользователи могут управлять PHP cron событиями? Является ли это потенциально опасным?

Only users with the edit_files capability can manage PHP cron events. This means if a user cannot edit files via the WordPress admin area (i.e. through the Plugin Editor or Theme Editor) then they also cannot add, edit, or delete a PHP cron event in WP Crontrol. By default only Administrators have this capability, and with Multisite enabled only Super Admins have this capability.

If file editing has been disabled via the DISALLOW_FILE_MODS or DISALLOW_FILE_EDIT configuration constants then no user will have the edit_files capability, which means adding, editing, or deleting a PHP cron event will not be permitted.

Therefore, the user access level required to execute arbitrary PHP code does not change with WP Crontrol activated.

Если константа CRONTROL_DISALLOW_PHP_EVENTS определена и установлена в значение true, то PHP cron события будут полностью отключены. Все существующие PHP cron события сохранятся (и могут быть удалены, если это разрешено правами пользователя), но их PHP код не будет выполняться при запуске события, и никакие PHP cron события не смогут быть добавлены, отредактированы или запущены.
