Thinkphp列表搜索排序-----查

一、控制器

// 列表
    public function lst()
    {
        $model = D(‘Goods‘);
        // 获取带翻页的数据
        $data = $model->search();
        $this->assign(array(
            ‘data‘ => $data[‘data‘],
            ‘page‘ => $data[‘page‘],
        ));

        $this->display();
    }

二、模型中数据的查询

public function search()
    {
        /************ 搜索 ****************/
        $where = array();
        // 商品名称的搜索
        $goodsName = I(‘get.goods_name‘);
        if($goodsName)
            $where[‘goods_name‘] = array(‘like‘, "%$goodsName%");
        // 价格的搜索
        $startPrice = I(‘get.start_price‘);
        $endPrice = I(‘get.end_price‘);
        if($startPrice && $endPrice)
            $where[‘price‘] = array(‘between‘, array($startPrice, $endPrice));
        elseif ($startPrice)
            $where[‘price‘] = array(‘egt‘, $startPrice);
        elseif ($endPrice)
            $where[‘price‘] = array(‘elt‘, $endPrice);
        // 上架的搜索
        $isOnSale = I(‘get.is_on_sale‘, -1);
        if($isOnSale != -1)
            $where[‘is_on_sale‘] = array(‘eq‘, $isOnSale);
        // 是否删除的搜索
        $isDelete = I(‘get.is_delete‘, -1);
        if($isDelete != -1)
            $where[‘is_delete‘] = array(‘eq‘, $isDelete);
        /***************** 排序 ******************/
        $orderby = ‘id‘;  // 默认排序字段
        $orderway = ‘asc‘; // 默认排序方式
        $odby = I(‘get.odby‘);
        if($odby && in_array($odby, array(‘id_asc‘,‘id_desc‘,‘price_asc‘,‘price_desc‘)))
        {
            if($odby == ‘id_desc‘)
                $orderway = ‘desc‘;
            elseif ($odby == ‘price_asc‘)
                $orderby = ‘price‘;
            elseif ($odby == ‘price_desc‘)
            {
                $orderby = ‘price‘;
                $orderway = ‘desc‘;
            }
        }
        /************ 翻页 *************/
        // 总的记录数
        $count = $this->where($where)->count();
        // 生成翻页对象
        $page = new \Think\Page($count, 2);
        // 获取翻页字符串
        $pageString = $page->show();
        // 取出当前页的数据
        $data = $this->where($where)->limit($page->firstRow.‘,‘.$page->listRows)->order("$orderby $orderway")->select();

        //echo $this->getLastSql();

        return array(
            ‘page‘ => $pageString,
            ‘data‘ => $data,
        );
    }
