PHP Heaven is running a tutorial on building WordPress plugins. The tutorial is aimed at developers with a solid understanding of PHP and some familiarity with WordPress. I watched a similar tutorial live at WordCamp Portland in 2009, and it's true: if you know PHP and the correct WordPress commands, you can build a a marginally useful plugin in less than ten minutes.
The steps, as outlined in the tutorial:
- First: Decide on the name of your plugin and create a plugin folder.
- Second: Make an index.php file within your folder and add the plugin description code.
- Third: Create an Admin Page.
Check out the tutorial for the details.
