README

Core Drupal module for the RSVP System — a theme and recipe cookbook for building calendar-based CMS sites with Drupal.

Purpose

This module implements Drupal hooks that must live in a module, not a theme. Drupal's ModuleHandler::invokeAll() does not invoke theme implementations of hooks like hook_views_query_alter and hook_views_pre_render.

Current hooks

hook_views_query_alter — Calendar event filtering

Injects two SQL filters into the rsvp_event_calendar Views block:

1. Month-range filter — restricts events to those starting within the calendar month. The view receives a YYYY-MM-DD date string as args[0] (passed from the calendar_month node template via drupal_view()).

2. Community filter — restricts events to those belonging to the same community as the calendar month page. The community taxonomy term ID is passed as args[1].

The smart_date Date argument plugin cannot produce month-range queries, so null contextual filters are used in the view and all real filtering is done here.

hook_views_pre_render — FullCalendar initialDate / validRange

Sets initialDate and validRange on the FullCalendar JS options so the calendar widget renders at the correct month rather than defaulting to today.

Installation

composer require rsvp-system/rsvp-system-module
