Install profiles in Drupal allow users to easily enable modules, set default themes and content, and create roles during site installation. They consist of PHP files that provide instructions to Drupal's install process. Install profiles make common setup tasks easier by automating repetitive configuration work. Users can start with basic profiles and expand their functionality over time.

Drupal Install Profiles
The coolest thing you're not customizing on Drupal... yet.

2. @chillin411
What is an install profile?
• Set of instructions that Drupal runs during the install
process
• Easy way to ENABLE (compare to DOWNLOAD using
Drush Make) modules at install.
• Can do practically anything using PHP

3. @chillin411
Why should I use them?
• Extremely easy to write
• Can start small and add to it as time goes by
• There's no reason to do the same setup tasks over and
over.
• Does the 2nd half of the work that you do with Drush
Make.

4. @chillin411
Cool things you can do:
• Enable modules at install
• Set an administration theme
• Add a new input format and configure it to use CKEditor
• Add users, nodes, or roles
• Create default content
• Anything you can do with PHP

Drupal 6 Install Profiles
• Composed of one file.profile
• Several PHP hooks
o hook_profile_modules()
o hook_profile_details()
o hook_profile_task_list()
o hook_profile_tasks()
o hook_form_alter()

Drupal 7 Install Profiles
• Consists of 3 files
o profile.info
 Similar to a module .info file (install modules here)
o profile.install
 Similar to a module's .install file (most of your
editing will go here)
o profile.profile
 Similar to a module's .module file (form_alters, etc)

7. @chillin411
Cool thing #1 - Enabling Modules
• D6 - hook_profile_modules()
o return array('views', 'views_ui', 'token');
• D7 - profile.info
o dependencies[] = views
dependencies[] = views_ui
dependencies[] = token

8. @chillin411
Cool thing #2 - Default Themes
• variable_set('admin_theme', 'Rubik');
o D6 - Put in hook_profile_tasks
o D7 - Put in hook_install
• variable_set('theme_default', 'Bartik');

9. @chillin411
Cool thing #3 - Create Admin Role
• D6 - hook_profile_tasks()
o $form_state = array();
$form_state['values']['name'] = 'Administrator';
$form_state['values']['op'] = t('Create admin role');
drupal_execute('user_admin_new_role', $form_state);
• Alternatively, you can use a db_query, but be careful about this -
notice lack of INTO, and lack of rid key.
o db_query("INSERT {role} (name) VALUES ( 'Administrator')");

How to get started?
• In Drupal 6, copy the /profiles/default folder, rename the
folder, .profile and function hook names to match your
profile.
• In Drupal 7, use the /profiles/standard instead of
profiles/minimal (more stuff there to work with)
• If you're enabling modules, make sure to have them
already downloaded. Drush make is awesome for this.
• Start editing, and looking at variables table.

11. @chillin411
One trick on the variables table
• Variables in the variable table are serialized.
o a:3:{i:0;s:4:"node";i:1;s:8:"taxonomy";i:2;s:4:"user";}
o array(0 => "node", 1 => "taxonomy", 2 => "user")
• So, if you want to add this to the variables table
(pathauto does this automatically, just an example)
o $array_pathauto_modulelist = array(0 => "node", 1 =>
"taxonomy", 2 => "user");
o variable_set('pathauto_modulelist',
$array_pathauto_modulelist);

12. Thanks!
