Simple WordPress Plugin Development - Start to Finish

In this specific tutorial, we will be focusing on building a contact form plugin, it will allow you save submissions into the database using a Custom Post Type, as well as send the submission via email. You'll also have a plugin options page to add any special options you'd like to customise how your plugin works. I've tried to address security issues like Sanitisation, Nonces and ways to protect your plugin and WordPress installation in general.
There's obviously a lot more stuff we can do with it, but to keep this tutorial simple as possible, I've addressed the most common needs for a plugin. In future, I will add to this specific plugin extra features. So stay tuned!
