Current code
<?php
function theme_more_help_link($variables) {
return '<div class="more-help-link">'. l(t('More help'), $variables['url']) . '</div>';
}
?>
Render array to replace that:
<?php
$more_help_link = array(
'#type'=> 'link',
'#href'=> 'admin/help/forum',
'#title'=> t('More help'),
);
$container = array(
'#theme'=> 'container',
'#children'=> drupal_render($more_help_link),
'#attributes'=> array(
'class'=> array('more-help-link'),
),
);
$output = drupal_render($container);
?>
