Accessing models from helpers

[eluser]Zack Kitzmiller[/eluser]
It's more of a best practice thing vs. a performance thing.

I usually call helpers in a few to format things I get from a database. So.

Example:

Controller

Code:

function all_users() {
    ...
    $data['users'] = $this->model->get_all_users();
    ...
}

View

Code:

<? if (!empty($users) : ?>
<ul>
    &lt;? foreach($users as $user): ?&gt;
        <li>&lt;?= full_name($user); ?&gt;</li>
    &lt;? endforeach; ?&gt;
</ul>
&lt;? endif; ?&gt;

Helper

Code:

function full_name($user) {
  return $user['firstname'] . ' ' . $user['lastname'];
}
