The WordPress Way

A tongue-in-cheek look at coding standards in the WordPress core and the average WordPress plugin.

1. # Declare variables global - in case they're going to be used again
2. All function/method parameters should be strings (e.g. 'yes'/'no') - for clarity
3. Functions and methods should return mixed types
4. No need to separate PHP logic from HTML, JS or CSS
5. Don't worry about PHP Notices - they're not important

 * Problem: WordPress MultiSite sends user signup mails from the main site. This is a problem when using domain mapping functionality as the sender is not the same domain as expected when creating a new user from a blog with another domain.
 * Solution: Change the default user notification mail from using the main network admin_email and site_name to the blog admin_email & blogname
