The user's account information is being displayed.
The module should format its custom additions for display and add them to the $account->content array.
$account: The user object on which the operation is being performed.
$view_mode: View mode, e.g. 'full'.
$langcode: The language code used for rendering.
Note: this list is generated by pattern matching, so it may include some functions that are not actually implementations of this hook.
function hook_user_view($account, $view_mode, $langcode) {
if (!isset($account->content['summary'])) {
$account->content['summary'] = array();
}
$account->content['summary'] += array(
'#type' => 'user_profile_category',
'#title' => t('History'),
'#attributes' => array(
'class' => array(
'user-member',
),
),
'#weight' => 5,
);
$account->content['summary']['member_for'] = array(
'#type' => 'user_profile_item',
'#title' => t('Member for'),
'#markup' => format_interval(REQUEST_TIME - $account->created),
);
}
