thinkPHP的数据添加、修改、删除

数据添加

1、通过关联数组的方法添加

$data = array(
    'goods_name' => '手机',
    'goods_price' => 2121
);
//返回值，如果第一列为自动增长列，则返回编号，不是自动增长，成功了返回1，错误返回0
echo M('goods')->add($data);

2、通过AR(active record)方式来添加

$goods = M('goods');
$goods->goods_name = '电视';
$goods->goods_price = 12312;
//返回值，如果第一列为自动增长列，则返回编号，不是自动增长，成功了返回1，错误返回0
echo $goods->add();

1、通过关联数组的方式

$data = array(
    'goods_name' => '手机2222',
    'goods_price' => 123,
    'goods_id' => 139
);
echo M('goods')->save($data);

2、通过AR的方式

$goods = M('goods');
$goods->goods_name = '电视2131231';
$goods->goods_price = 12312;
$goods->goods_id = 140;
echo $goods->save();

1、参数为主键

M('goods')->delete(140);

2、批量删除

M('goods')->delete('138, 139');

3、条件删除

（1）M('goods')->where('goods_name = "手机"')->delete();

（2）$model = M('goods');
$model->goods_name = '手机';
$model->delete();

查询：

$list = M()->query('select * from goods');

增删改：

M()->execute('delete from goods where goods_id = 1');
