block_qr - QR Code block for Moodle

The block_qr plugin adds a configurable block that generates QR codes directly in Moodle contexts (course pages, activities, dashboard, and more).

It is designed for quick sharing of links and structured content to mobile devices without copying URLs manually.

Features

• Generate QR codes directly from a block instance.
• Multiple QR content modes (links, internal Moodle targets, event, geolocation, WiFi).
• Configurable QR size per block instance.
• Optional integration with a URL shortener service.
• Multiple block instances are supported.

Available QR target modes

When editing a block instance, you can choose one of the following modes via Content (config_options):

1. currenturl - Link to the current page
   Encodes the exact URL of the page where the block is shown.

2. courseurl - Link to this course
   Encodes the course URL and optionally allows a description text.

3. internalcontent - Link to a section or activity
   Lets you select either:

   • a course section (section=<sectionid>), or
   • a course module/activity (cmid=<cmid>).

4. owncontent - Text/URL
   Encodes custom text or a custom URL (for links, use https://...).

5. event - Event
   Encodes iCalendar-style event data including title, location, start, end, and all-day option.

6. geolocation - Geolocation (lat/lon)
   Encodes coordinates and can optionally include a map link target.

7. wifi - WiFi
   Encodes WiFi setup information (SSID, hidden SSID flag, authentication type, optional password).

Configuration

Block instance settings

Each block instance can configure:

• Content mode (see list above)
• Mode-specific fields (e.g., section/activity target, event data, geolocation, WiFi settings)
• QR size (small, medium, large)

Global plugin setting

The plugin supports a configurable short-link service URL (configshortlink). If configured, a short-link action can be shown in block editing mode.
