为什么我的产品无法再首页了显示，是不是调用错了？

调用哪里错了吗？
$sjtoday_wh['add_time'] = array(array('egt',$today_str),array('elt',$tomorr_str)) ;
  $sjtoday_wh['pass'] = '1';
  $sjtoday_item = $this->_mod->where($sjtoday_wh)->count();
  $this->assign('sjtoday_item', $sjtoday_item);

  $jtoday_wh['add_time'] = array(array('egt',$today_str),array('elt',$tomorr_str)) ;
  $jtoday_wh['pass'] = '1';
  $jtoday_wh['coupon_price'] = array('elt','9.9');
  $jtoday_item = $this->_mod->where($jtoday_wh)->count();
  $this->assign('jtoday_item', $jtoday_item);
