function flag_enable in Flag 6.2

Same name and namespace in other branches

1. 5 flag.install \flag_enable()
2. 7.2 flag.install \flag_enable()

Implements hook_enable().

We create the demonstration flag on enable, so hook implementations in flag module will fire correctly, as the APIs are not available on install.

File

./flag.install, line 46

Flag module install/schema/update hooks.

Code

function flag_enable() {

  // Load the flag API in case we want to use it when enabling.
  include_once drupal_get_path('module', 'flag') . '/flag.module';
  if (!flag_get_flags()) {

    // Install a demonstration flag only if no flag exists. This is to prevent
    // a case where a disables and enables the module, and the demonstration
    // flag is overwritten or re-created.
    $flag = flag_flag::factory_by_content_type('node');
