About

Calendar link provides two Twig functions for generating links for various calendaring services.

Requirements

This module does not require any additional modules outside of Drupal core.

This module uses the spatie/calendar-links library as its foundation. Use composer to install the module (see INSTALLATION) or run composer require spatie/calendar-links separately.

Installation

Install with composer to ensure dependencies are also installed: composer require 'drupal/calendar_link'
Install as you would normally install a contributed Drupal module. See: https://drupal.org/documentation/install/modules-themes/modules-8 for further information.

Configuration

There is no configuration available for this module.

Use

This module provides two new Twig functions for generating calendar link URLs:

calendar_link: Returns a string link for a specific calendar type. Available types are:
- Apple iCal/Microsoft Outlook (ics)
- Google calendar (google)
- Office 365 (webOffice) (version 3.x only)
- Outlook.com (webOutlook)
- Yahoo! calendar (yahoo)
calendar_links: Returns an array of links for all available calendar types. Each array element has the following keys/data:
- type_key: The calendar type key (ics, google, etc.)
- type_name: The calendar type name ("iCal", "Google", etc.)
- url: The URL for the calendar item

Examples

Assume an example "Event" node with the extras fields:

Title (string title)
Start date/time (datetime field_start)
End date/time (datetime field_end)
All day event (boolean field_all_day)
Description (string field_description)
Location (string field_location)

In a twig template, the following code with generate a link to the event to a Google calendar:

{% set link = calendar_link('google', node.title, node.field_start, node.field_end, node.field_all_day, node.field_description, node.field_location) %}
<a href="{{ link }}">Add to Google</a>

Or, to create a list of links for each service:

{% set links = calendar_links(node.title, node.field_start, node.field_end, node.field_all_day, node.field_description, node.field_location) %}
<ul>
{% for link in links %}
  <li>
    <a href="{{ link.url }}" class="calendar-link-{{ link.type_key }}">{{ link.type_name }}</a>
  </li>
{% endfor %}
</ul>

Using with Views

When using values from Views results only the default formatter for date fields is supported. Most other date field formatters do not provide necessary timezone data in rendered results to ensure correctness of the generated calendar links. See #3249457: Views support for further details and discussion.
