Google Calendar API - PHP - 设置事件的颜色

Question

我们如何在使用 Google Calendar API (PHP) 插入事件时设置颜色？

Answer 1

这是我编写的一个 PHP 函数和我提取的 PHP 客户端库的一部分，以允许我在日历中创建事件、删除事件等，但代码只是为了向您展示 colorId 需要设置的位置以及使它工作的语法。

Google 将为您可以设置 colorId 的前 11 个整数中的每一个显示颜色。

1 蓝色

2个绿色

3 紫色

4 红色

5 黄色

6 橙色

7 绿松石

8 灰色

9 粗体蓝色

10 粗体绿色

11 粗体红色

    $client = get_google_client($calendar_name); // ID of your Google calendar
    $capi = new GoogleCalendarApi($client);

    $event['event_time']['start_time'] = $start_time; // Start time of event
    $event['event_time']['end_time'] = $end_time;     // End time of the event
    $event['summary'] = $heading;                     // The title of the event
    $event['location'] = $address;                    // Address field of event
    $event['description'] = $details;                 // Body of the event
    $event['colorId'] = 3;                            // colorId of event (see above)
    $event['attendees'] = $calendar_name;

Answer 2

creating an event 时可以设置可选的colorId 属性。您可以从colors endpoint 检索颜色列表。

Answer 3

在这里，您可以找到要为事件插入的颜色的每个 idColor Google Calendar id Color for events
