This is how I implemented the required label using an advanced theme (note, labels are in German, yellow button):
function voting_inner_html($post)
{
$this->vote_buttons($post);
// $this->vote_count($post);
$this->vote_clear();
}
function vote_buttons($post)
{
$this->output('<div class="qa-vote-buttons '.(($post['vote_view']=='updown') ? 'qa-vote-buttons-updown' : 'qa-vote-buttons-net').'">');
$likes = $post['raw']['upvotes'];
$peoplePlural = ($likes!=1) ? 'Personen' : 'Person';
$buttonlabel = 'Gefällt '.$likes.' '.$peoplePlural.' • Dir auch?';
$buttonlabel2 = 'Gefällt '.$likes.' '.$peoplePlural;
if($likes==0) {
$buttonlabel = 'Gefällt dir der Beitrag?';
$buttonlabel2 = 'Gefällt dir der Beitrag?';
}
switch (@$post['vote_state'])
{
case 'voted_up':
$this->post_hover_button($post, 'vote_up_tags', $buttonlabel2, 'qa-vote-one-button qa-voted-up');
break;
case 'voted_up_disabled':
$this->post_disabled_button($post, 'vote_up_tags', $buttonlabel2, 'qa-vote-one-button qa-vote-up');
break;
case 'voted_down':
$this->post_hover_button($post, 'vote_down_tags', '–', 'qa-vote-one-button qa-voted-down');
break;
case 'voted_down_disabled':
$this->post_disabled_button($post, 'vote_down_tags', '–', 'qa-vote-one-button qa-vote-down');
break;
case 'up_only':
$this->post_hover_button($post, 'vote_up_tags', $buttonlabel, 'qa-vote-first-button qa-vote-up');
$this->post_disabled_button($post, 'vote_down_tags', '', 'qa-vote-second-button qa-vote-down');
break;
case 'enabled':
$this->post_hover_button($post, 'vote_up_tags', $buttonlabel, 'qa-vote-first-button qa-vote-up');
$this->post_hover_button($post, 'vote_down_tags', '–', 'qa-vote-second-button qa-vote-down');
break;
default:
$this->post_disabled_button($post, 'vote_up_tags', '', 'qa-vote-first-button qa-vote-up');
$this->post_disabled_button($post, 'vote_down_tags', '', 'qa-vote-second-button qa-vote-down');
break;
}
$this->output('</div>');
}
