here select box not fill fn_add_setting_info() data. how can . please me.

in func.php  function fn_settings_variants_addons_sharesoft_fancycolor_order_status()     {          $all_datas=get_feature_description();            foreach($all_datas $val){                $arr_sett[$val['feature_id']]=$val['description'];            }              return $arr_sett;     }    addon.xml    <item id="order_status">                         <type>selectbox</type>                         <default_value>fn_add_setting_info</default_value>                     </item>
