12. Running Drupal
Visit – www.cubettech.com

like a different location
 Index.php does bootstrapping:
checks database for enabled modules
loads modules that are appropriate
checks permissions
queries database for content
applies theme
renders the page

13. How to install Drupal
Visit – www.cubettech.com
 You need a database and a web server with PHP already running
 Create a database for the Drupal site
 Download the Drupal code from Drupal.org
 Point web browser to Drupal root and the rest is automated

Module
Theme
Block
Node
Content Type
Taxonomy
Menu
User Roles and Permissions
Views

15. Modules - functionality
Visit – www.cubettech.com
 Modular piece of code that extends Drupal
 Uses the Drupal API
 Just a set of functions defined in the Drupal core (or
other modules)
 Can be enabled/disabled (in the database)
 Provide additional functionality without altering the
Drupal core

16. Themes - Look and Feel
Visit – www.cubettech.com
 Many components of Drupal are defined in the “theme”
 Themes are mainly comprised of HTML, CSS, PHP and images
 Themes utilize the same hierarchy as modules
 Theme files are called “templates”

17. Blocks
Visit – www.cubettech.com
 Blocks are pieces of content placed in regions of Drupal pages
 Blocks are arbitrary pieces of content
 Usually the stuff that appears in sidebar, header and footer content
 Blocks can be content, forms, special lists, polls, or arbitrary HTML
 Themes define regions for blocks

18. Nodes
Visit – www.cubettech.com
Drupal organizes most content around the concept of a “node”
Nodes are just pieces of content
Only a few things aren't nodes – users, groups, modules, and themes being
the main ones
Other stuff, from calendar events, to RSS feed items, to page content is a
node

19. How Nodes Work
Visit – www.cubettech.com
 Nodes support versioning
 As a result node content is stored in the node_revisions table
 The Drupal “node” table stores basic data about nodes
 Nodes can have various modules applied to them to adjust input and
output handling

20. Content Types
Visit – www.cubettech.com
 “Basic Page” and “Article” are two default content types
 Content types define input fields and how the content is displayed
 New content types can easily be created
 Content type creation should follow careful consideration of site
architecture and purpose

21. Taxonomy
Visit – www.cubettech.com
Taxonomy is another way to organize content
 Taxonomy are “tags” that are applied to content
 “Vocabularies” set up as taxonomies
 Vocabularies then contain terms
 Taxonomies can be extended and used for various rules in the Drupal back
end
 Taxonomy can also be used for display purposes

22. Menus
Visit – www.cubettech.com
Drupal menu system is also fairly arbitrary
 Display and positioning is controlled by themes
 Three default menus:
Navigation
Primary links
Secondary links

23. Users and Roles
Visit – www.cubettech.com
 Users are assigned to roles
 By default two roles are defined in Drupal
Authenticated User
Anonymous User

24. Permissions
Visit – www.cubettech.com
Drupal utilizes a Role Based Access Control (RBAC) system
 Users are assigned to roles, roles receive permissions
 Permissions are set through the Drupal administrative interface
 Userid 1 user (created during install) has all permissions

25. Views
Visit – www.cubettech.com
 The views module allows administrators and site designers to create, manage, and
display lists of content.
 Each list managed by the views module is known as a "view", and the output of a
view is known as a "display".
 Displays are provided in either block or page form, and a single view may have
multiple displays.
 For more technical users, views can be understood as a user interface to compose
SQL-queries, pulling information (Content, Users, etc.) from the database and showing
it on screen in the desired format.
 The "building block" design of the views system provides power and flexibility,
allowing parameters to be specified only when needed.

26. Viewsis a query builder
Visit – www.cubettech.com
The first fundamental thing you need to know about Views is that it is a tool
to build queries. You can even inspect the query as you build it.

27. Custom Module Development
Visit – www.cubettech.com
A Drupal site can have three kinds of modules (the 3 Cs):
Core modules that ship with Drupal and are approved by the core
developers and the community.
Contributed modules written by the Drupal community and shared under
the same GNU Public License (GPL) as Drupal.
Custom modules created by the developer – often for a particular use case
specific to the site they're working on.

28. Hook system for Drupal modules
Visit – www.cubettech.com
 Hooks are how modules can interact with the core code of Drupal.
 They make it possible for a module to define new urls and pages within
the site (hook_menu), to add content to pages (hook_block, hook_footer,
etc.), to set up custom database tables (hook_schema), and more.
