function comment_modules_enabled in Drupal 7

Implements hook_modules_enabled().

Creates comment body fields for node types existing before the comment module is enabled. We use hook_modules_enabled() rather than hook_enable() so we can react to node types of existing modules, and those of modules being enabled both before and after comment module in the loop of module_enable().

There is a separate comment bundle for each node type to allow for per-node-type customization of comment fields. Each one of these bundles needs a comment body field instance. A comment bundle is needed even for node types whose comments are disabled by default, because individual nodes may override that default.

Install, update and uninstall functions for the comment module.

Code

function comment_modules_enabled($modules) {

  // Only react if comment module is one of the modules being enabled.
  // hook_node_type_insert() is used to create body fields while the comment
  // module is enabled.
  if (in_array('comment', $modules)) {

    // Ensure that the list of node types reflects newly enabled modules.
    node_types_rebuild();

    // Create comment body fields for each node type, if needed.
    foreach (node_type_get_types() as $type => $info) {
      _comment_body_field_create($info);
    }
  }
