Introduction As a web developer I often deal with wordpress clients wanting to build, change or migrating their websites to a different platform. There are times, you deal with different environment on setting up your configurations. The following are my must have on my configurations: 1. DB_NAME, DB_USER, DB_PASSWORD, DB_HOST The database information. This enable us to connect to our database. 2. WP_SITEURL, WP_HOME The URL of your site. Defining this constants would make your life easier especially when you are trying to debug your changes in your development environment.
