在Fuelphp查询构建器中使用"()"

Question

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.

我该怎么解决这个问题？

您可以使用->where_open/close查询构建器的分组方法:

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')
