我想在fuelphp这样的sql中使用“()”。
select * from shop where (item1=$item1 or item2=$item1) and flag=on;
我试着像这样表达;
$shop_query = DB::select()->from('shop');
$shop_query->where(function($shop_query){
$shop_query->where('item1','=',$item1)
->or_where('item2','=',$item1);
$shop_query ->and_where('flag','=','on');
但是,这显示错误:undefined index item1.$item1
,当然它有值。
我怎么解决这个问题?

您可以使用查询构建器的分组->where_open/close
方法:
public static function whatever($item1, ... the rest of your args)
{
$shop_query = DB::select()
->from('shop')
->where('flag', 'on')
->and_where_open()
->where('item1', $item1)
->or_where('item2', $item1)
->and_where_close()
->execute()->as_array(); // just change this to whatever you need
return $shop_query;
}
这变成了:
SELECT * FROM `shop` WHERE `flag` = 'on' AND (`item1` = '$item1' OR `item2` = '$item1')
