Together with clou kreativ (www.cloukreativ.ch) we create www.biginlucerne.com, a photo contest in Lucerne, Switzerland. We used Drupal as a tool to allow users upload, rate, comment, share images. In this presentation Slava Rys explains some core functions, problems that occured during development as well as some insight about how the site was built. Also find additional comments on www.netnode.ch/blog

• How biginlucerne.com is built using Drupal
• Challanges and solutions

3. What is biginlucerne.com?
• Photo contest
• Social media campaign for Lucerne tourism
Client
www.lucerne.com
Design & concept by
www.cloukreativ.ch

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

14. Get next image
Performance trick
• The views module was skipped
• Get next image using db_select()

15. Code example

16. Biggest problem
• Voting process
• Facebook Open Graph
• Facebook integrations
