How to generate barcode images by just typing their values into a wiki page.

Description

In order to let your wiki pages generate and display barcodes, just follow these simple steps:

1. Download and install any barcode-generating script (here you'll find two opensource examples, please google for more)
   • http://www.ashberg.de/php-barcode/
   • http://www.geocities.com/wcattebeke/files.html link broken 2009-12
2. Test your install by typing the proper url into your browser, something like
   • http://www.example.com/barcode/barcode.php?code=1234456694147&mode=png&scale=3
     a barcode image should show. If it does, paste the same url into your wiki page. As you save, the url will show on your page.
3. Add "&.png" to the url in order to fool your wiki and let it print the image, and not the url itself
   • http://www.example.com/barcode/barcode.php?code=1234456694147&mode=png&scale=3&.png
     a barcode should show now, and not the url any more.
4. If you like to have your barcode fetch its value from some other page, please
   • define some variable in Group.SomePage (example "Name: John")
   • reference your variable this way http://www.example.com/barcode/barcode.php?code={Group.SomePage$:Name}&mode=png&scale=3&.png
