The QRLite extension allows to generate QR codes as .png and .svg images. It generates and embeds them "on the fly" and does not store them as MediaWiki images.

Installation edit

  • Ensure that the GD PHP extension is installed (e.g. on Debian issue: apt install php-gd and then restart apache, if not already installed).
  • Download, extract and place the file(s) in a directory called QRLite in your extensions/ folder.
  • Only when installing from Git, run Composer to install PHP dependencies, by issuing composer install --no-dev in the extension directory. (See task T173141 for potential complications.)
  • Add the following code at the bottom of your LocalSettings.php file:
    wfLoadExtension( 'QRLite' );
  •   Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Instead of downloading the zip archive you may also check this extension out via Git:

git clone https://github.com/gesinn-it/QRLite.git

Usage edit

Use the #qrlite parser function.

Available Parameters
  • format - svg or png. Default is png
  • size - A number that defines the overall QR code image size. Default is 6.
  • margin - A number, default is 0
  • ecc - A number ranging from 0 to 4 that defines the error correction level. Default is 2.
