qr_generator

Overview

The QR Generator module lets you create, manage, and host QR codes directly in Drupal with built-in redirection management, branding options, and advanced export controls.

Modes

Online QR codes — Hosted in Drupal with automatic redirects, usage tracking, and optional expiration.
Offline (self-contained) QR codes — Embeds the full target data (URL or text) directly into the code so it works without an internet connection or a Drupal server.

Requirements

- PHP ^8.3 (Fully tested on PHP 8.4)
- Drupal Core ^10 or ^11

Dependencies

- Core: rest and serialization modules
- Third-party: endroid/qr-code (^5.0 or ^6.0) — QR code generation
- Third-party: setasign/fpdf (^1.8) — PDF export support

New Features (1.0.3)

- Branding with Logos: Upload an image or provide a URL to embed your company logo directly into the center of the QR code.
- Custom Labels: Add descriptive text labels (e.g., "Scan Me") below the QR code.
- Color Customization: Full support for custom foreground and background colors using Hex codes.
- Advanced Export Settings: Precision control over pixel size, margins, and Error Correction Levels (Low, Medium, Quartile, High).
