4. Lets talk about key functions
• Facebook integration
• Voting mechanism
• Get next image for voting process

5. Facebook integrations
Problems & solutions
• Fbconnect — does not work well yet
• Fb — the best module for FB integrations

6. FB module functions?
• Connect FB account to user
• Development tools
• Views integrations
• Rules integrations
• Example module
• And lot of other functions...

7. Why is this cool?
• No problem with instalations and setup (all works
from the box)
• Easy UI
• Good documantation

8. The FB module hook
hook_fb_user ($op, $data, &$return) {}
$op:
• FB_USER_OP_PRE_USER- Before account creation, fb_user.module
• FB_USER_OP_POST_USER - After account creation, fb_user.module
• FB_USER_OP_POST_EXTERNAL_LOGIN - user map has changed global user.
• FB_USER_OP_POST_USER_CONNECT - Connected local account to FB account,
fb_user.module
• FB_USER_OP_POST_USER_DISCONNECT - Disconnected local account from FB
account, fb_user.module

9. Lets talk about the voting process
Problems & solutions
• The flag module was skipped
• Voting API & rate modules — the best solution for
voiting process

10. Drupal Voting API module is cool!
The Voting API does four key jobs for module developers:
• CRUD: Create/Retrieve/Update/Delete operations for voting data.
• Calculation: Every time a user creates a vote, VotingAPI calculates the results
and caches them for you.
• Workflow: By integrating with Actions.module, VotingAPI can trigger workflow
steps (like promoting a node to the front page, hiding a comment that's been
flagged as spam, or emailing an administrator) when votes are cast and results
are tallied.
• Display: VotingAPI integrates with Views.module, allowing you to slice and dice
your site's content based on user consensus.

11. Drupal rate module is cool!
• This module provides flexible voting widgets for
nodes and comments.
• Administrators can add multiple widgets. By default,
there are 8 widget types
• By using "custom" you can customize the rating
buttons and Voting API mode. Widget types can be
extended by other modules.
• Flexible API

12. The Rate module hooks
• hook_rate_templates() {}
• hook_rate_widget_alter(&$widget, $context) {}
• hook_rate_widget_insert(&$widget, $values) {}
• hook_rate_widget_update(&$widget, $values) {}
• hook_rate_widget_delete(&$widget) {
• hook_rate_vote_alter($vote, $context) {}

13. Code example
