There are a two different ways you can insert code into your WordPress site to add functionality.

1. Add the code into the php file

2. Use widgets for your sidebar

In this tutorial we are mainly going to look at doing it in your php file and later we will look at using widgets. As we did with the CSS Style Sheets if you make a mistake just upload that specific php file and it will all go back to the default.

You can use this method to add opt in forms, add products and services and just about anything you would like to improve your site.

For scripts and code in your pages and posts you would do better to add a plugin for things like videos, audios etc.

For Audio and Video I use Podpress.
