Luzid Content Scheduler

Luzid Content Scheduler controls when a specific frontend block is visible — and can also output the next scheduled date(s) via shortcode.

This gives you two complementary ways to use a scheduler:

1. Show / hide a block (banner, alert, section, popup wrapper, …) Add the generated CSS class luzid-cs-<slug> to the element. The plugin adds body classes and a tiny frontend helper so the block is only displayed while the schedule is active.

2. Display dates in the frontend Use the shortcode to print the next event (or a list of upcoming events) anywhere in your content.

Typical Use Cases

• Maintenance banners: Show a “We’re updating our systems” notice only during scheduled maintenance windows.
• Seasonal content: Display holiday greetings, special offers, or seasonal menus during specific date ranges.
• Event announcements: Print “Next event: Saturday, March 15th at 7 PM” dynamically on any page.
• Recurring schedules: Show “Happy Hour specials” every Friday from 5 PM to 8 PM.
• Multi-stage visibility: Use Event Classes to show a popup 4 days before an event, the full content 2 weeks before, and a menu item 11 days before — all independently controlled.
• Event calendars: Generate a table of all upcoming events across multiple schedulers.

Core Concepts

• A scheduler becomes active when at least one rule matches (single dates/ranges or recurring rules).
• Exceptions override everything: if “now” is inside an exception range, the block is hidden even if other rules match.
• Event Classes (new in 1.4) allow multiple independent visibility windows with different offsets — each generating its own CSS class.
• The shortcode reads the same event logic and outputs formatted dates with full control over separators and formatting.

Features

Scheduling

• Single dates & date ranges: Define specific days or periods when content should be visible.
• Recurring rules: Weekly (every Monday), Monthly (every 15th), Weekday in month (2nd Thursday), Yearly (February 14th).
• Exceptions: Override all rules — content stays hidden during exception periods.
• Event Classes: Create multiple CSS classes per scheduler, each with independent visibility offsets.

Shortcode Output

• Flexible date/time formatting: Choose from short, medium, long, or full date formats.
• Separators: Control exactly what appears between date, time, and text parts.
• Lists: Output multiple upcoming events with customizable separators.
• Event Table: Generate a sortable table of all upcoming events from multiple schedulers.
• Time offset: Shift the displayed time (e.g., “doors open 30 minutes before”).

Administration

• Card-based UI: Clean, modern interface for managing rules.
• Live preview: See upcoming events and visibility windows instantly.
• Bilingual: Full German and English support with one-click language switching.

Event Classes (New in 1.4)

Event Classes allow you to create multiple independent visibility windows for a single scheduler. Each class has its own CSS class and offset settings.

Example setup:

Class CSS Class Days Before Use Case

Standard .luzid-cs-dinner 14 Main content

popup .luzid-cs-dinner-popup 4 Announcement popup

menu .luzid-cs-dinner-menu 11 Navigation menu item

This allows you to control when different elements appear, all based on the same event schedule.

CSS Hooks

Shortcode output: * .luzid-cs — Wrapper (plus .luzid-cs--single / .luzid-cs--list) * .luzid-cs-item — Single event in list * .luzid-cs-date — Date part * .luzid-cs-time — Time part * .luzid-cs-text — Event text * .luzid-cs-sep / .luzid-cs-sep1 / .luzid-cs-sep2 — Separators

Event table: * .luzid-cs-eventtable — Table wrapper * .luzid-cs-eventtable__head / __body / __row / __cell

Body classes (for conditional CSS): * .luzid-cs-active-<slug> — Added when scheduler is active * .luzid-cs-active-<slug>-<classname> — Added when specific event class is active
