Since I have started developing my ‘GD Pages Navigator’ widget plugin, I wanted to upgrade it so it can support more then one instance on a page. Unfortunatly there are limited resources available for that task, and almost no info about it in the official documentation. There are plugins that use different methods of achiving this, but best method is the one used by plugins build into Wordpress.

So, my starting point was ‘widget.php’ file where this default widgets are located. They also provided a short example of multi instance widget at the end of this file. This example in is good, but it has few errors (copy-paste errors mostly). This function is in the sample code class

I have decided to walk you throught the process of creating a widget that will support more then one instance. This example will show you how to work with different types of settings and it will provide you with some practicle code snippets you can use in your own plugins. Tutorial will be based on my ‘GD Pages Navigator’ plugin. This widget supports multiple instances from the version 3.0.0.
