Drupal 7 Module Development

Drupal Permissions and Security
If the current user passes this access check, we must then fetch the information we
want. This information is not about the $user but about the $account being viewed.
So we add the logic:
/**
* Implement hook_user_view().
*/
function example_user_view($account, $build_mode) {
if (!user_access('view user roles')) {
return;
}
// Get the user's roles.
$list = $account->roles;
if (!empty($list)) {
// Prepare the information for theming.
$variables = array(
'items' => $list,
);
$content = theme('item_list', $variables);
// Attach the content to the user page according to the API.
$account->content['summary']['output'] = array(
'#type' => 'user_profile_item',
'#title' => t('User roles'),
'#markup' => $content,
'#attributes' => array('class' => array('content-creation')),
);
}
}
When implemented, our code produces the following result on a user page:
