ecmall 数据库操作

$model为实例化模型对象;

1.查询一条数据

//$id 主键值

$model->get_info($id);

 

2.查询多条数据  并分页

$page = $this->_get_page();
$datas = $model->find(array(
'conditions' => '1=1' . $conditions,
'limit' => $page['limit'],
'count' => true,
'order' => 'sort_order',
));

$this->_format_page($page);
$this->assign('page_info', $page);

 

3.统计数据条数

$count = $model->getCount();

 

//自定义数据操作
 $sql = "UPDATE {$mod_goods->table} " .
                            "SET cate_id_1 = '{$cate_id_n[0]}', cate_id_2 = '{$cate_id_n[1]}', cate_id_3 = '{$cate_id_n[2]}', cate_id_4 = '{$cate_id_n[3]}' " .
                            "WHERE cate_id = '$cate_id'";
  $mod_goods->db->query($sql);

$row = $store_mod->get(array(
'conditions' => $param['store_id'],
'fields' => 'store_name'
));

　　

 添加信息成功失败跳转

        if ($this->_authaccount_mod->get_error())
        {
            $this->show_warning('添加失败');
            //$this->show_warning($this->_authaccount_mod->get_error());
            return;
        }
        $this->show_message('添加成功',
            '','index.php?app=my_authaccount'
        );
