Who the hell are you? •Contract designer-developer •Mostly a front-end
guy •Hates smelly code •Likes clean & simple

What EE is •$300 + add-ons •Flexible •Client friendly •Mature

ass for you or your clients

documentation •Built on CodeIgniter

of content (products, news, etc) 2. Create custom ﬁelds for each channel 3. Enter Content 4. Build templates for each channel

Creating Channels 1. Custom Fields 2. Publish Form 3. Templates

Creating a Channel 1. Custom Fields

Add-Ons •Plugins •Modules •Extensions •Field Types

Add-Ons Plugins •Simplest of all •Just a single class •Used
on the front end

Add-Ons Anatomy of a Plugin Front end: {exp:plugin_name variable="value"} In
pi.plugin_name.php: Class plugin_name { function plugin_name() { ... } }

Add-Ons Modules •Most advanced type of add-on •Has views, admin
class, front- end class, language ﬁle •Uses CodeIgniter classes

Add-Ons Module Admin Class Example Class module_name { function index()
{ $total = $this->EE->db->count_all($this->table); $query = $this->EE->db->get('table_name'); return $this->EE->load->view('index', $vars, TRUE); } ... more functions for each action }

Add-Ons Extensions • Like plugins, but for control panel •
Uses hooks to alter functionality • Multiple extensions can use the same hook

Add-Ons Field Types • Most common add-on type • Add
functionality to entry administration
