在mongodb PHP中同时获取嵌套数组和更新字段

Question

我在mongodb的collection中具有以下值。现在，我想获取数组single为status和1为transferred的数组内的0字段。但是我也想在同一查询中将set transferred到1，这样我就不必编写多个查询。

以下是我的收藏

{
        "_id" : ObjectId("5b5c268af93afb77f9d904db"),
        "vendor_id" : ObjectId("5b17b991c440782b5a218cd1"),
        "single" : [
                {
                        "product_id" : ObjectId("5af5619d977f8723188a8f81"),
                        "product_type_id" : ObjectId("5ae834807ae0d9538e45ab45"),
                        "condition_id" : ObjectId("5ae978587ff1706f3b7dc47e"),
                        "selling_price" : 100,
                        "quantity" : "27",
                        "shipping" : "44",
                        "date_added" : "2018-07-28-08-17-14",
                        "date_live" : 0,
                        "status" : 1,
                        "flag" : 0,
                        "transferred" : 0
                },
                {
                        "product_id" : ObjectId("5af2bd44a003533a8abf4e56"),
                        "product_type_id" : ObjectId("5ae834807ae0d9538e45ab45"),
                        "condition_id" : ObjectId("5ae978187ff1706f3b7dc47c"),
                        "selling_price" : 200,
                        "quantity" : 403,
                        "shipping" : 702,
                        "date_added" : "2018-08-21-10-39-47",
                        "date_live" : 1,
                        "status" : 1,
                        "flag" : 0,
                        "transferred" : 0
                },
                {
                        "product_id" : ObjectId("5af2bd44a003533a8abf4e56"),
                        "product_type_id" : ObjectId("5ae834807ae0d9538e45ab45"),
                        "condition_id" : ObjectId("5ae977da7ff1706f3b7dc47a"),
                        "selling_price" : 100,
                        "quantity" : 809,
                        "shipping" : 11,
                        "date_added" : "2018-09-04-13-44-10",
                        "date_live" : 0,
                        "status" : 0,
                        "flag" : 0,
                        "transferred" : 0
                }
        ]
}

到目前为止，我已经写了这篇文章

$pipeline=[
				[
					'$match'=>
						[
							  'vendor_id'=>$vendor_id,
							  'single.status'=>1,
							  'single.transferred'=>0
						]
				],
				[
				   '$project'=> 
				  		[
				  			  'single'=>1
				  		]
				]
			];

但是我无法set将转移的值设为1
