YOURLS-IQRCodes

YOURLS Integrated QRCodes plugin with exposed options and full integration

This is an updated fork of Inline QRCode which is more compact, configurable, and just as efficient with more features.

Updating to v2.0.0 + from the 1.x.x branch may cause some unexpected behavior. Deleting the cache and re-generating qr codes may be necessary. Note, attempting to install this before the required U-SRV will result in failure.

Requires:

YOURLS 1.7.3 ready. Works with YOURLS 1.7.2 U-SRV v2.0.0 +

Features

Old

• QRCodes are generated and cached for every new short url
• A new QRCode is generated when a short url is edited
• Cached QRCodes are deleted when its corresponding short url is deleted
• QRCodes are displayed within the sharebox whenever the sharebox is displayed
• QRCodes are generated for pre-existing shorturls when sharebox is displayed
• Codes are generated from a standalone php based QRCode library
  • No calls to google!

New

• All options are available in the admin interface
  • Code size
  • Border width
  • ECC level
  • Image file type
  • Optional logo watermark (image preview, scale, location on QR Code)
  • Image cache location
  • Auto-delete or preserve cache on plugin deactivation
• Scan the entire database at once and generate QR Codes for any short url that is found to be missing one
• Plenty of well documented, practical examples in the options page to help get started with integration
• Code links are served using U-SRV, a secure system allowing greater integration
• Updated and minimized md5.js
• Streamlined version of the QR Code generation library
• Almost 1/2 the size of its predecessor
  • This can halfed again by disabling and deleting the PHP QR Code cache, which was left in for enhanced performance. This setting can be found on lnie 100 of assets/phpqrcode.php
• Append .qr to any short url to display qr code

Installation

1. Download and install YOURLS and U-SRV. U-SRV will have created it's cache, within which will sit the IQRCodes's cache.
2. Download the latest release of this repo and extract the iqrcodes folder to YOURLS/user/plugins/
   • the following commands are run from YOURLS root folder. Eg, /absolute/path/to/YOURLS
3. Symlink or copy qrchk.php into the pages folder. Automation of this task is planned for a future release.
   • Symlink:
     ln -s user/plugins/iqrcodes/assets/qrchk.php pages/qrchk.php
   • Copy:
     cp user/plugins/iqrcodes/assets/qrchk.php pages/qrchk.php
4. Set permissions and cache
   • There needs to be two cache folders (relative to YOURLS root)
     • user/plugins/iqrcodes/cache
       is included with the plugin download
     • /path/to/U-SRV/cache/qr
       iqrcodes will attempt to create this
   • In case of failure just do somethign like the following (as root):
     • mkdir /PATH/TO/U-SRV/CACHE/qr
     • chmod -R 777 /PATH/TO/U-SRV/CACHE
     • chown -R www-data:www-data /PATH/TO/U-SRV/CACHE
     • chown -R www-data:www-data /PATH/TO/YOURLS/user/plugins/iqrcodes
5. Enable module, default config works fine, or visit IQRCodes page to fine tune.
6. Have fun!

Note:

If you are using YOURLS with Nginx and using this directive, you may end up with 404's instead of images. You may want to have a look at this comment and thread.

If this becomes an issue, try changing

(try_files $uri $uri/ /yourls-loader.php;)

to

if (!-e $request_filename){ rewrite ^(.+)$ /yourls-loader.php?q=$1 last; }
