public function ModuleHandlerInterface::enable

Enables or installs a given list of modules.

Definitions:

• "Enabling" is the process of activating a module for use by Drupal.
• "Disabling" is the process of deactivating a module.
• "Installing" is the process of enabling it for the first time or after it has been uninstalled.
• "Uninstalling" is the process of removing all traces of a module.

Order of events:

• Gather and add module dependencies to $module_list (if applicable).
• For each module that is being enabled:
  • Install module schema and update system registries and caches.
  • If the module is being enabled for the first time or had been uninstalled, invoke hook_install() and add it to the list of installed modules.
  • Invoke hook_enable().
• Invoke hook_modules_installed().
• Invoke hook_modules_enabled().

Parameters

$module_list: An array of module names.

$enable_dependencies: If TRUE, dependencies will automatically be added and enabled in the correct order. This incurs a significant performance cost, so use FALSE if you know $module_list is already complete and in the correct order.

Return value

FALSE if one or more dependencies are missing, TRUE otherwise.
