Embedding calendars

Web authors can use PHP functions provided with TUCAL to easily include interactive calendar views in web pages. This requires JavaScript on the client side.

This functionality is specifically intended for publishing group calendars (configurable in the IdM portal) with the possible content gradations of Availability Only, Restricted Details, and Read Permissions.

To use it, the php/calendar.inc file must be included in the page header:

# Include calendar functions
require_once('php/calendar.inc');
  1. Functions
    1. calendar_init(string|array $url [, string $id, array $options])
    2. calendar_show([string $id])
  2. Examples

Functions

calendar_init(string|array $url [, string $id, array $options])

Initializes a calendar view. Must be called before seite(…) is called.

  • Field with multiple calendar addresses and associated options:
    array(array('source' => 'CAL1HASH', …), array('source' => 'CAL2HASH', …))
    (The possible options are marked with # in the explanation of $options.)
