Вывод текста с бд для всех пользователей кроме одного SimplaCMS

В SimplaCMS я добавил в раздел группы пользователей, описание и обозвал его text_group. Есть две группы пользователей id=2 и id=15, ну и конечно id=1(админский)

Вывожу в tpl так

{$group->text_group}

для group_id==2

А как для всех пользователей, даже если не реганный или админ, видели текст с group_id==15

???

UPD

В api пытался добавить group_text

function get_groups(/*group_discount*/$filter = array()/*/group_discount*/ )
  {
    /*group_discount*/
        $order = 'g.discount';
        $discount_filter = '';
        if (isset($filter['is_discount'])) {
            $discount_filter = $this->db->placehold('AND g.is_discount=?', intval($filter['is_discount']));
        }
        /*/group_discount*/
    
    /*group_visible*/
    $filter_for_visible = '';
    if (isset($filter['for_visible'])) {
        $filter_for_visible = $this->db->placehold('AND g.for_visible=?', intval($filter['for_visible']));
        }
    /*/group_visible*/          
    
    // Выбираем группы
    $query = $this->db->placehold("
    SELECT g.id, g.name, g.text_group, g.discount, g.is_discount, g.short_name, g.for_visible
        FROM __groups AS g
    WHERE 
    1 
    $discount_filter 
    $filter_for_visible         
        ORDER BY g.discount
    ");
    $this->db->query($query);
    return $this->db->results();
  } 
  
  function get_group($id)
  {
    // Выбираем группу
    $query = $this->db->placehold("SELECT * FROM __groups WHERE id=? LIMIT 1", $id);
    $this->db->query($query);
    $group = $this->db->result();

    return $group;
  }
  
    function get_group_text($id)
  {
    // Выбираем группу
    $query = $this->db->placehold("SELECT * FROM __groups WHERE id=15 LIMIT 1", $id);
    $this->db->query($query);
    $group = $this->db->result();

    return $group_text;
  }

Сама groupadmin.php
