The document provides tips and best practices for developing Joomla sites as part of a team. It discusses using version control like SVN or Git, following coding standards for naming conventions and formatting, and leveraging tools for code review and team development. Additional suggestions are given for debugging, moving sites, testing for injections, and speeding up sites through techniques like removing Mootools and using content delivery networks. The presenter encourages sharing ideas to improve Joomla development.

2. Intro

3. Quick Questions firstHow many here work as a team developing projects?

4. How many have used SVN or GIT?

5. How many of you are developers?

6. How many of you are experts?

7. How many of you would like to make more money by working faster?Coding StandardsWhat is a coding standards?

8. Have higher quality / improved standards of released products / web sites

9. Easier to maintain from developer to developerNaming ConventionsClasses:

10. Classes should be given descriptive names. Avoid using abbreviations where possible.

11. Separate each word with underscore.

12. We use underscores instead of Camel Case (like Joomla!)

13. Private Class members are preceded with _

14. Example: _init_tree()Function Definitions This example is based on the K&R styleDescriptionsDescriptions are important as it helps other developers determine what is going on in the code itselfCoding Standards Example

15. Coding Standards TricksMake sure all coding is done with Maximum Error Reporting or E_STRICT

16. Make sure all your developers use the same patterns and have there IDE or favorite text editor setup properly to interpret the code.

17. Some example references:

20. http://docs.joomla.org/Coding_style_and_standardsSVN vs GITSpeed

21. Handling of the repository

22. Size of repositories

23. Maturity of the repository

24. Ability to move to different versionsWhy use SVN or GIT?Ability to work with code with a team of developers

25. Copy of revision code

26. Apply immediate backups to a last known working revision

27. See who performed the update

28. Version control allows you to bring your new member up to speed with branches for testing instead of using actual live code to test.Which is betters?GIT of course!

29. You can use GIT off the grid – instead of being connected to the network

30. GIT is fast and leaner then other systems

31. Easy to useReferenceshttp://svnbook.red-bean.com/

33. Software based code review

34. Blame

39. AssemblaDevelopment TricksThe following are tips and tricks of developing that will enhance and make Joomla! development more focused.Don’t use die for debug$mainframe->close();

40. Because of how PHP5 handles code database connection errors can occur similar to the following if using a die();

41. Warning: mysqli_query() [<a href='function.mysqli-query'>function.mysqli-query</a>]: Couldn't fetch mysqli in /home/corephptest/public_html/libraries/joomla/database/database/mysqli.php on line 147Use the Joomla! framework elsewhereWith Joomla! you can extract the framework and use inside of applications out side of the CMS

42. Example would be http://www.corephp.com/members

43. This is a complete system that pulls in Joomla! modules / data into a 3rd party system WHMCS natively.How do you?/* Initialize Joomla framework */ define( '_JEXEC', 1 ); define( 'JPATH_BASE', dirname( __FILE__ ) ); define( 'DS', DIRECTORY_SEPARATOR ); /* Required Files */ require_once ( JPATH_BASE .DS.'includes'.DS.'defines.php' ); require_once ( JPATH_BASE .DS.'includes'.DS.'framework.php' ); /* To use Joomla's Database Class */ require_once ( JPATH_BASE .DS.'libraries'.DS.'joomla'.DS.'factory.php' ); /* Create the Application */ $mainframe = JFactory::getApplication( 'site’ );// Your code starts here...

44. Move a site with easeAkeeba Backup

45. Configure to use FTP for backup

46. Will backup to the new server that all the data was backed up to

47. Execute installation on new server.Quick DebuggingHere is a nifty example of doing quick debug – lets assume we have a lot of logic in our debug output:/* */print_r($var);// Other logic printing// Other debug code here// Blah blah blah/* */

48. Note how /* */ starts at the top and bottom

49. Add a space to the first one /* * / and the code is now commented out. Uncomment to have execute.Quick DebuggingAre you having an issue with trying to find where the code is located that is causing the issue?

50. Load the following code at the bottom of your index.php (last line)

51. debug_print_backtrace();Single or Double QuoteIn PHP there is a difference when using either single or double quotes, either ‘ or “. If you use double quotes ” then you are telling the code to check for a variable. If you are using single quotes ‘ then you are telling it to print whatever is between them. This might seem a bit trivial, but if you use the double quotes instead of the single quotes, it will still output correctly, but you will be wasting processer time.Test for SQL InjectionsTest your code. SQL injections are common in many applications and you can prevent it by testing. Here is a great cheat sheet:

52. http://ferruh.mavituna.com/sql-injection-cheatsheet-oku/#AboutMySQLandPHPRemove MooToolsRemove mootools and any unnecessary scripts loading to the page.

53. $user =& JFactory::getUser();if ( $user->get( 'guest' ) == 1 ) { $document =& JFactory::getDocument(); $headerstuff = $document->getHeadData();reset($headerstuff['scripts']);foreach ($headerstuff['scripts'] as $key=>$value){ if (substr_count($key, 'mootools') > 0)unset($headerstuff['scripts'][$key]); } $document->setHeadData( $headerstuff );}Speeding up your sitesUsing CDN support on your site will increase the speed of the site.

54. Using products like jomCDN or other CDN solutions will help decrease the speed of your site and increase your score.

55. Why?

56. Assets are loaded from servers that are close to you and not directly from the server the data is being served from.Share and work togetherShare development concepts that workGot a great idea for Joomla! – lets us know and help improve the platform and CMS
