Pro adds capabilities that aren’t included here. **Technical Note: Database Architecture** This plugin integrates `webcalendar-core`, a framework-agnostic Composer library that provides all calendar business logic (events, recurrence, iCal, permissions) through 17 repository classes. These repositories require PDO and use exclusively parameterized prepared statements — no raw SQL concatenation. WordPress-specific data (users, options, capabilities) is accessed via `$wpdb` through the plugin’s Bridge layer (`WpUserRepository`, `WpConfigRepository`, etc.). See `src/Bridge/PdoFactory. php` for the connection factory. ### External Services This plugin connects to the following third-party services: #### Nager.Date API Used for importing public holidays via WebCalendar > Holidays. * Endpoint: https:// date.nager.at/api/v3/ * [Terms of Use](https://date.nager.at/LegalNotice) * [Privacy Policy](https://date.nager.at/Privacy) #### Google Calendar Public Feeds Alternative holiday source. Fetches public .ics files from Google. * Endpoint: https://calendar.google.com/calendar/ical/ * [Google Privacy Policy](https://policies.google.com/privacy)* [Google Terms of Service](https://policies.google.com/terms) #### Thunderbird Holiday Calendars Alternative holiday source via community-maintained .ics files. * Endpoint: https:// www.thunderbird.net/media/caldata/ * [Mozilla Terms of Use](https://www.mozilla.org/about/legal/terms/mozilla/)* [Mozilla Privacy Policy](https://www.mozilla.org/privacy/) #### Remote Calendar Sync (User-Configured) When remote iCal subscriptions are configured, the plugin fetches .ics data from those URLs via HTTP GET. No user data is transmitted to these services. #### OpenStreetMap / Nominatim When a single event page has a location and the map provider is set to OpenStreetMap ( the default), the plugin geocodes the address via the Nominatim API and displays a map using OpenStreetMap tile servers. The event location string is sent as a search query. No user personal data is transmitted. * Geocoding endpoint: https://nominatim. openstreetmap.org/search * Tile server: https://tile.openstreetmap.org/ * [OpenStreetMap Terms of Use](https://wiki.osmfoundation.org/wiki/Terms_of_Use)* [Nominatim Usage Policy](https://operations.osmfoundation.org/policies/nominatim/)* [OpenStreetMap Privacy Policy](https://wiki.osmfoundation.org/wiki/Privacy_Policy) #### Google Maps Embed API When the map provider is set to Google Maps in settings, single event pages display an embedded Google Map for the event location. The event location string and your Google Maps API key are sent to Google. No other user data is transmitted. * Endpoint: https://www.google.com/maps/embed/v1/place * [Google Maps Platform Terms of Service](https://cloud.google.com/maps-platform/terms)* [Google Privacy Policy](https://policies.google.com/privacy) #### Add to Calendar Links Single event pages include “Add to Calendar” buttons that generate links to Google Calendar, Outlook.com, and Yahoo Calendar. When a visitor clicks a button, the event title, date, time, location, and description are passed as URL parameters to the chosen service. No data is sent until the visitor clicks. * Google Calendar: https:// www.google.com/calendar/render — [Terms](https://policies.google.com/terms) | [Privacy](https://policies.google.com/privacy)* Outlook.com: https://outlook.live.com/calendar/0/action/compose — [Terms](https://www.microsoft.com/servicesagreement) | [Privacy](https://privacy.microsoft.com/privacystatement) * Yahoo Calendar: https:// calendar.yahoo.com/ — [Terms](https://legal.yahoo.com/us/en/yahoo/terms/otos/index.html) | [Privacy](https://legal.yahoo.com/us/en/yahoo/privacy/index.html) #### Social Sharing Links Single event pages include social sharing buttons for Facebook, X (Twitter), and LinkedIn.

Use the `[webcalendar]` shortcode or add the **WebCalendar Calendar** block in the block editor. Both support AJAX navigation between months without page reloads. ### Can I import events from Google Calendar? Yes. Export your Google Calendar as an `.ics` file and use **WebCalendar > Import** to import it. You can also use **WebCalendar > Remote Calendars** to subscribe to a public Google Calendar iCal URL for automatic syncing. ### How do I migrate from another calendar plugin? Export your existing calendar as an `.ics` file (most calendar plugins support this), then import it via **WebCalendar > Import**. This works with any plugin or service that exports standard iCalendar files. ### Does the plugin support recurring events? Yes. When creating or editing an event, use the recurrence builder to set daily, weekly, monthly, or yearly patterns. You can edit individual instances or the entire series. ### What happens to my data if I uninstall the plugin? By default, all calendar data is preserved when you uninstall. To delete all data on uninstall, enable the “Delete Data on Uninstall” option in **WebCalendar > Settings**. ### Can different users have different permissions? Yes. The plugin registers 36 capabilities mapped to WordPress roles. Administrators can manage all settings and events, Editors can manage events and categories, and Authors can create and manage their own events. ### Does it work with page builders like Elementor or Divi? Yes. Use the `[webcalendar]` shortcode inside any page builder. The calendar renders responsively inside any container. ### Does the calendar work with my theme? The calendar uses standard WordPress styles and adapts to your theme’s container width. It is designed to be responsive and works on desktop, tablet, and mobile. ### What is your versioning and compatibility policy? WebCalendar follows [Semantic Versioning](https://semver.org/).

Resolves PDOException[ HY000] [2002] “Can’t assign requested address” reported on plugin activation. * Fix: Activation no longer aborts on database connection errors — data seeding( categories, holiday calendar, layer subscriptions) is wrapped in try/catch and queued for lazy retry on the next admin request. * Fix: REST API validators for optional positive-int fields (category_id, featured_image_id, originalEventId) now accept `null`/`0`/`""` as “not provided” instead of returning HTTP 400. Resolves admin form save failures when no category was selected. * Fix: REST `owner` validator accepts the empty-string “global owner” sentinel used by categories and nonuser calendars. * Test: New WP_DEBUG E2E lane scans wp-content/debug.log around every test and fails on plugin-originated PHP notices/warnings/deprecations/fatals/PDOException/ _doing_it_wrong. 39 critical-flow specs covering activation lifecycle, REST write paths, and rendering surfaces. * Test: New socket-only MySQL activation lane reproduces the WP.org reviewer environment( MariaDB –skip-networking + DB_HOST=localhost) end-to-end as a regression guard. * Bumped craigk5n/webcalendar-core to ^4.3.2 (includes PdoEventRepository::search() fix for reused :keyword named placeholder under native prepares). #### 1.0.2 * Security: remote-calendar sync and webhook delivery now use wp_safe_remote_* to block private-IP / cloud-metadata destinations (SSRF hardening) * Security: admin file uploads (CSV and iCal import) now route through wp_handle_upload() with an explicit MIME allowlist; temp uploads are cleaned up via wp_delete_file() * Security: added direct-file-access guards (defined(‘ABSPATH’) || exit) to all directory index stubs * Security: REST export-route _wpnonce inputs are sanitized via sanitize_text_field( wp_unslash()) before wp_verify_nonce() * Security: REST write routes now declare explicit args schemas with per-field sanitize_callback and validate_callback on all 23 POST/PUT/DELETE endpoints across 8 controllers * WP-CLI import/export commands now use WP_Filesystem instead of raw file I/O * Added “Development & Source Code” readme section with build instructions for plugin reviewers * Fixed: popup “View Event Details” link works with emoji event titles * 1,038 automated tests (+23 new regression guards), PHPStan Level 9, 0 PHPCS errors on changed code * WP.org Review Sprint #2 — all 11 findings from the third-pass review are resolved #### 1.0.1 * Single event pages now display participant list * Calendar frontend fetches all pages of events (fixes missing events on busy days) * Recurring event detail pages show correct occurrence date * Plugin slug changed to `agenticdaisy-calendar` per WordPress.org review * Added external service disclosures (OpenStreetMap, Google Maps, social sharing, add-to-calendar) * Converted inline scripts to wp_add_inline_script() per WordPress coding standards * Renamed wpApiSettings JS global to webcalApiSettings to avoid reserved wp_ prefix * Bundled Leaflet locally instead of loading from CDN * WordPress Plugin Check: 0 errors (all resolved) * WordPress coding standards compliance fixes * Added PDO usage documentation for plugin reviewers * 1,126 automated tests, PHPStan Level 9, 86%+ coverage #### 1.0.0 * Initial release * Full calendar admin UI with month/week/day views (Toast UI Calendar) * Event CRUD via REST API with recurring events (RRULE support) * Categories with color coding and layer-based calendar filtering * iCal import/export and remote calendar subscription with automatic sync * `[webcalendar]` shortcode and Gutenberg blocks (Calendar, Upcoming Events) * Single event pages with SEO-friendly permalinks and Schema.org JSON-LD * Open Graph and Twitter Card meta tags for social sharing * Social share buttons and “Add to Google/Outlook/Yahoo” one-click buttons * Global holiday management with standard US holiday import * Conflict detection with “Save Anyway” option for overlapping events * Email notification system with invitation templates and reminders * Role-based access control (36 capabilities) * All features fully unlocked — no license gating * REST API rate limiting and event pagination with safety caps * 1,126 automated tests, PHPStan Level 9 ## Meta * Version **1.0.3** * Last updated **1 day ago** * Active installations **Fewer than 10** * WordPress version ** 6.6 or higher ** * Tested up to **6.9.4** * PHP version ** 8.2 or higher ** * Language * [English (US)](https://wordpress.org/plugins/agenticdaisy-calendar/) * Tags * [calendar](https://ory.wordpress.org/plugins/tags/calendar/)[event calendar](https://ory.wordpress.org/plugins/tags/event-calendar/) [events](https://ory.wordpress.org/plugins/tags/events/)[ical](https://ory.wordpress.org/plugins/tags/ical/) [scheduling](https://ory.wordpress.org/plugins/tags/scheduling/) * [Advanced View](https://ory.wordpress.org/plugins/agenticdaisy-calendar/advanced/) ## Ratings No reviews have been submitted yet.
