## Description

Displays a calendar (Google Calendar, Apple Calendar/iCloud, Microsoft 365 /
 Outlook
Calendar, or Konzertmeister – via iCal/ICS link) as an agenda list, in the style
of “date box on the left, title/date/time/location/description on the right”. No
click behavior (no modal, no redirect) – text remains normally selectable/copyable.

Provided free of charge by [KlangAgenda.de](https://klangagenda.de) – on
 Klangagenda.
de you can promote your concerts free of charge across your region, book rehearsal
and concert venues, and offer your own space to others to make better use of it.

All settings (including a detailed step-by-step guide for each calendar
 provider)
are available in the WordPress backend under the dedicated top-level menu “Klangagenda
Kalender” (with its own calendar icon).

#### Shortcodes

**[klangagenda]**
 Shows all upcoming events (including recurring ones, e.g. weekly
rehearsals).

**[klangagenda_no_recurring]**
 Shows upcoming events WITHOUT recurring events (
e.g. only concerts/special events, no weekly rehearsals).

**[klangagenda_konzerte]**
 Shows only events whose title contains the word “Konzert”(
German for “concert”, case-insensitive), e.g. “Winterkonzert”, “Sommerkonzert”, “
Adventskonzert”. By default shows neither a date badge nor a description per event–
instead, the description of the first (next) event is shown once at the top of the
whole list.

By default, this shortcode shows no “Buy tickets” button per event.
 The attribute`
ticket_button="ja"` turns this on. `beschreibung="nein"` hides the intro description
at the top, and `badge="ja"` shows the date badge per event:

    ```
    [klangagenda_konzerte ticket_button="ja" badge="ja" beschreibung="nein"]
    ```

“(+)”/”(-)” markers (e.g. from Konzertmeister sync) are automatically
 stripped 
from event titles in all shortcodes.

All shortcodes accept an optional `count` attribute, e.g.
 [klangagenda count=”5″].
If omitted, the default count from the plugin settings is used.

#### Fixed date window per post (ab / bis)

Normally the shortcodes automatically show the next upcoming events
 from now on.
For the typical workflow (one post per concert tour/period; once it’s over the post
moves into the archive and a new post with the next dates is created), there are
optional attributes ab (from) and `bis` (until) (format YYYY-MM-DD):

    ```
    [klangagenda_konzerte ab="2026-09-01" bis="2026-09-14"]
    ```

This makes this specific post permanently show exactly the events in
 this time 
window – even once they’re in the past. `ab` and `bis` can also be used individually.

#### “Load more” button

[klangagenda] and [klangagenda_no_recurring] automatically show a
 “Mehr Termine”(
load more) button below the list whenever more events are available beyond the currently
shown count. Clicking it loads more events via AJAX (no page reload). The button
does not appear on the [klangagenda_konzerte] shortcode and can additionally be 
hidden explicitly via `[klangagenda button="nein"]`.

#### “orchestriert von klangagenda.de”

Below each event list (or below the “load more” button, if present),
 a subtle, 
light-gray, centered note “orchestriert von klangagenda.de” appears by default, 
linking to https://klangagenda.de. This note can be fully switched on or off in 
the backend under “Klangagenda Kalender”.

#### Recurring events (RRULE)

RRULE processing covers the common patterns (daily/weekly/monthly/
 yearly, interval,
count, end date, weekdays). Recurring events without an end date are pre-calculated
up to the configured time horizon (default 12 months), and continued automatically
on the next sync.

#### Ticket button

The button appears when the title contains “konzert” and the
 description contains
an http(s) link. Only the first link found is used.

## Changelog

#### 2.5.1

 * Fix: increased spacing below the month heading (introduced in 2.5.0) so it
    no
   longer sits too close to the following event.

#### 2.5.0

 * The corner radius of the “Tickets kaufen” and “Mehr Termine” buttons is now
    
   configurable.
 * Font size and color for the event title, date, location and description
    are 
   now individually configurable in the backend.
 * Optional month headings (e.g. “Oktober 2026”) can now be shown between
    events
   whenever the month changes.

#### 2.4.0

 * The per-event description can now be shown or hidden, and its text color
    is 
   configurable in the backend.
 * When the description is hidden, each event becomes clickable and opens a
    popup
   with the full event details (title, date, location, description) instead – text
   selection/copying on the rest of the list is unaffected.
 * The “Kalenderansicht” preview cards now also show the description color
    and 
   the popup behavior live.

#### 2.3.2

 * Fix: after automatically (re-)creating the events table (see 2.3.1), the
    calendar
   is now also synchronized immediately, instead of waiting for the next scheduled
   sync (up to 30 minutes) or a manual click on “Jetzt synchronisieren”.

#### 2.3.1

 * Fix: the events database table is now also created/repaired on every
    page load
   if missing, not only on plugin activation. This prevents “table doesn’t exist”
   errors when the plugin is updated by overwriting its files (e.g. via FTP or a
   hosting file manager) instead of being deactivated/reactivated through the WordPress
   admin.

#### 2.3.0

 * Added three additional card-style calendar views (date on the right with
    an 
   accent-colored left border, date on the left, and a full-height accent-colored
   date block) as alternatives to the standard date badge.
 * New backend section “Kalenderansicht” under Settings to preview all
    available
   views live (using the currently configured colors, even before saving) and select
   the active one.
 * New configurable card background color for the card-style views.

#### 2.2.0

 * Removed the legacy `[google_agenda]` / `[google_agenda_no_recurring]`
    / `[google_agenda_konzerte]`
   shortcode aliases introduced in 2.0.0; please switch any existing pages to `[
   klangagenda]` / [klangagenda_no_recurring] / `[klangagenda_konzerte]`.

#### 2.1.0

 * Prepared for release in the WordPress plugin directory (full plugin
    header, 
   GPLv2 license, readme.txt in WordPress.org format, English readme, dropped “Plugin”
   from the plugin name).
 * All internal identifiers (classes, functions, options, database
    table, asset
   handles, hooks) renamed to a distinctive `klanca_` / KLANCA_ prefix; settings
   from the predecessor plugin are migrated automatically on activation.
 * webcal:// links are stored/displayed unchanged and automatically
    switched to
   https:// internally when fetched.
 * Sync interval changed to 30 minutes (custom WP-Cron interval).
 * Frontend hint renamed to “orchestriert von klangagenda.de” and now
    hidden by
   default; site administrators must actively opt in via a checkbox in the settings
   before it is shown.
 * All CSS and JavaScript are now loaded via `wp_enqueue_style()` /
    wp_enqueue_script()
   instead of inline `<style>`/`<script>` tags.
 * Hardened output escaping and database queries per WordPress coding
    standards.

#### 2.0.0

 * Renamed to “Klangagenda Calendar Plugin” with its own top-level menu
    item in
   the WordPress backend.
 * Shortcodes renamed to [klangagenda], [klangagenda_no_recurring],
    [klangagenda_konzerte](
   previous [google_agenda] shortcodes remain functional for backward compatibility).
 * New “Anleitung” tab with step-by-step instructions per calendar
    provider.
 * Optional “powered by” hint on the frontend, toggleable in the
    backend.

#### 1.3.1

 * Fix: moved asset registration from `plugins_loaded` to
    wp_enqueue_scripts to
   avoid a WordPress notice (“headers already sent”) when saving other forms.

#### 1.3.0

 * Konzerte shortcode: toggles for ticket button, description, and date
    badge; 
   automatic removal of “(+)”/”(-)” markers from event titles.

#### 1.2.0

 * “Load more” button with AJAX loading and loading animation.
 * Configurable accent/hover colors.

#### 1.1.0

 * Separate concerts shortcode with automatic “buy tickets” button.
 * Fixed date windows (`ab`/`bis`) per post.

#### 1.0.0

 * Initial release: Google Calendar agenda view with RRULE support.
