- 2. About Jeff Fox (@jfox015) • Senior Level Web Developer • Veteran of two browser wars and the dot- com bubble • Fully self taught • Studied Art and Music Production • Baseball enthusiast (ney fanatic)
- 3. Meetup Overview • MVC, CodeIgniter and HMVC in 5 mins. • Intro to Bonfire (more than 5 minutes) • Anatomy of a Bonfire Module • Practical Example • Q&A
- 4. Modular Development Taking HUGE monolithic applications and breaking them into manageable pieces
- 5. Modular Development "How the heck do we do that?"
- 6. Model, View, Controller Controllers handle requests Models Views present information represent data to the user
- 7. CodeIgniter CodeIgniter • Popular Open Source PHP Framework • Simple MVC Based Architecture • Tons of tools and libraries to utilize in site development workflow • Flexible View system • Known for performance and documentation
- 8. CodeIgniter CodeIgniter • Originally built and released by Ellis Labs, the Expression Engine people • "Reactor" is the community driven build and release initiative • Core team of developers oversee active development and releases • One of the "big three" PHP Frameworks
- 10. Hierarchical Model, View, Controller HMVC Triads call on and use other MVC triads to accomplish goals of the application
- 12. Bonfire Basics CodeIgniter • Open Source library built on top of CodeIgniter • HMVC design using Modular Extensions • Pre-built Administrative Dashboard • Rich user authentication workflow • Variety of site admin tools and utilities
- 13. Bonfire Basics CodeIgniter • Dashboard utilizes "contexts" for building admin tools • Database migrations manage upgrades and fallbacks • Custom Model class with built in SQL helper functionality • Several classes of abstract controllers
- 14. Bonfire Basics CodeIgniter • Includes a system of roles to assign to users • Robust permissions allows for precise control over site privileges and user access • Standard system for storing and accessing site settings • Includes a Module Builder wizard to generate fully compatible new modules
- 15. Functional Highlights CodeIgniter • Contexts provide a loosely coupled way to build Admin tools • Naming conventions prevent hard coding menus • Each module can have its own admin tools and still stay loosely coupled
- 16. Functional Highlights CodeIgniter Themes and Templates • UI Based on the Twitter Bootstrap libraryBonfire uses a theme and template system for views • Numerous helper functions are available to send data to view classes, select themes, manually set views, set messaging and render the content

- 18. Functional Highlights CodeIgniter Migrations • Implements the CodeIgninter Migrations class • Adds ability for modules to use migrations • Auto loading of new migrations on app startup (configuable via settings) • Can use DBforge or Codeigniter Database Class and SQL
- 19. Functional Highlights CodeIgniter public function up() { $this->dbforge- >add_column('comments_threads', array('module' => array('type'=> 'VARCHAR','constraint' => 255,'default' => '')); } public function down() { $this->dbforge- >drop_column("comments_threads","module"); }
- 20. Functional Highlights CodeIgniter Assets Lib • Allows you to add JavaScript, images and CSS automatically in the head and/or footer of the site Assets::add_js($this->load- >view('thread_view_js',array('th read_id'=>$thread_id), true),'in line');
- 21. Functional Highlights CodeIgniter Modular Everything •All core Dashboard features are modules • Users • Translate Tool • Activities • Module Builder • Migrations • Logos • Permissions • Emailer • Roles • UI • Settings • Updater • Sysinfo • Database
- 22. Functional Highlights CodeIgniter Easy Install Two step install Like Wordpress
- 23. Bonfire Team CodeIgniter Lonnie Ezell Nuno Costa Project Founder Ben Evans Icehawg Sean Downey and many more on Github.com Shawn Crigger
- 24. Anatomy of a Bonfire Module
- 25. General Structure CodeIgniter • All third party and custom modules are stored in the "modules" folder in the bonfire directory. • Core modules live in the "core_modules" folder in the application directory.
- 26. General Structure CodeIgniter • Bonfire Modules are like little stand-alone CodeIgniter apps • Modules follow the context naming convention system to allow access to their controllers throughout the site • Can be 100% standalone or work with other modules • Optimally can be dropped into other apps
- 27. Naming Conventions CodeIgniter Controllers • Public accessible, add controller with a name that matches the modules folder name • Admin Dashboard (Also called the Springboard) Controllers, add a controller that matches the context name
- 28. Naming Conventions CodeIgniter Auto-Resolving Views • For public views, and index.php to the modules "Views" folder • Admin views, add a folder for the matching context in the "Views" folder with an index.php file in it.
- 29. Naming Conventions CodeIgniter Manually Resolving Views • In the controller, before calling Template::render(), add a line to set the view using Template::set_view('view'); • Any view from any loaded module can be used simply by specifying the module path and view name
- 30. Config CodeIgniter • config.php contains a simple array that identifies the module to the application and contain it's meta information • Config folder may contain other files used to store information about the app • Custom routes.php files can be used to add additional levels of URL->controller routing
- 31. Controllers CodeIgniter • Contains all controllers used by the modules • Should extend one of the four main Bonfire controller types: o Base_Controller o Front_Controller o Authenticated_Controller o Admin_Controller
- 32. Views CodeIgniter • Adding an index.php file to the views folder makes it publically accessible • Adding folders named for supported admin contexts with index.php files makes them accessible from admin menus • No limit to number of view files there can be, how they're organized outside context rules or how they're called
- 33. Misc CodeIgniter • Models follow general CI model rules. Should extend BF_Model to gain Bonfire helper functionality. • Migrations are used to install DB support and handle changes • Language files support translations • Can add helpers, libraries and assets as well
