数据库配置文件
shop/common/conf/config.php
控制器创建模型
new \Model\UseModel();
如果表明跟带后缀的名称不一样,只要在声明模型的时候加上
$protected trueTableName=' '
D 跟 new
D智能操作数据表,如果需要有其他功能,比如增加判断就只能用new
数据的基本操作
查询 select
$goods->select();select * from 'sw_goods'
$goods->select(12); select * from 'sw_goods' where 'goods_id' =12;
$goods->select (12,13,34,35);selext * from 'sw_goods' where 'goods_id' in ('12','13','3'4,'35');
{$v@iteration} 从一开始
具体的数据操作方法使用
select goods_brand_id ,conut(*) from sw_goods group by goods_brand_id;
select goods_brand_id ,avg(goods_price) from sw_goods group by goods_brand_id;
where gen having de qubioe
where 条件字段必须是数据表中存在的
having 条件字段必须在结果集中存在
数据添加
array方式
ar方式
$array=aray(
"goods_name"=>'nihao',
'goods_id'=>12,
)
$goods->add($array);
$goods->goods_name='nihao';
$goods->add();
删除
¥model->where()->delete
$model->goods_id=12;
$model->delete();
$model->delete(12);
原生sql语句
$model->query($sql); 查询,返回一个二维数组
$model->execute($sql);增删改 返回受影响的数据
$_POST['user_hobby']=implode(',',$_POST['user_hobby']);
protected $patchValidate=true;
protected $_validate=array(
)
array(验证字段,验证规则,错误提示【验证条件,附加规则,验证时间】)
