我编写了一个PHP脚本，以编程方式从Google日历事件创建自定义帖子，并编写了一个操作挂钩，用于清除所有现有事件并用当前事件重新填充。当我单击已添加到视图中的按钮时，效果很好。然而，当我尝试将钩子作为cron作业来执行时（使用WP控制插件），它会清除现有的帖子，但不会创建新的帖子。我从调试中得到的唯一输出是一个关于上下文帮助被弃用的警告，我认为这与此无关，但我当然可能是错的。

以下是代码（相关部分）：

function create_event_posts() {
  //calendar-ids and parameters are stored in variables outside of the function for reference in other functions
  global $calendarIds;
  global $optParams;

  //delete existing posts <-- This works fine! :)
  $allEvents = get_posts(array(\'post_type\' => \'event\', \'numberposts\' => -1));
  foreach ($allEvents as $eachEvent) {
    wp_delete_post($eachEvent -> ID, true);
  }

  //call to google calendar script
  require_once ABSPATH . \'path/to/vendor/autoload.php\';
  $client = new Google_Client();
  $client -> setApplicationName(\'customCalendar\');
  $client -> setAuthConfig(ABSPATH . \'path/to/credentials.json\');
  $client = getClient();
  $service = new Google_Service_Calendar($client);

  //collecting all the events
  foreach ($calendarIds as $calendarId) {
    $results = $service -> events -> listEvents($calendarId, $optParams);
    $events[] = $results -> getItems();
  }
  $events = flatten($events);

  foreach ($events as $event) {
    $eventContent = $eventTitle = $eventColor = $calendarTitle = \'\';
    $calendarTitle = $event -> organizer -> displayName;
    $eventContent = apply_filters(\'the_content\', $event -> getDescription());
    $start = $event -> start -> dateTime;
    $end = $event -> end -> dateTime;
    $fmt = new \\IntlDateFormatter(\'nb-NO\', NULL, NULL);
    $fmt -> setPattern(\'EEEE d. MMMM\');
    $outputDate = $fmt -> format(strtotime($start));
    $outputStart = date(\'H:i\', strtotime($start));
    $outputEnd = date(\'H:i\', strtotime($end));

    if (empty($start)) {
      $start = $event -> start -> date;
    }

    $eventPost = array(
      \'post_author\'   => 1,
      \'post_date\'     => date(\'Y-m-d H:i:s\'),
      \'post_content\'  => $eventContent,
      \'post_title\'    => $eventTitle,
      \'post_excerpt\'  => $outputDate . \', kl. \' . $outputStart . \' – \' . $outputEnd,
      \'post_status\'   => \'publish\',
      \'post_type\'     => \'event\',
      \'post_category\' => array($eventCategory), //I cut out the part where this variable is defined, to save space
      \'meta_input\'    => array(
        \'_EventStartDate\'  => $start,
        \'_Room\'            => $calendarTitle,
      ),
    );
    if (!post_exists($eventTitle, $eventContent, \'\', \'event\')) {
      $post_ID = wp_insert_post($eventPost);
    }
  }
}

add_action(\'admin_post_create_event_posts\', \'create_event_posts\');
