Nested SQL Query in Laravel Controller - php

Question

I have two queries running in my controller. I need a value from the first query to be passed into the second. I want the result of both these queries sent to my view.
public function jobs()
{
$query = DB::table("dbQuotes")
->leftJoin("dbACT", "dbQuotes.act_id", "=", "dbACT.ID")
->leftJoin("dbOpps", "dbQuotes.act_id", "=", "dbOpps.contactID")
->leftjoin('dbBids', 'dbQuotes.act_id','=',
DB::raw('dbBids.quote_id AND dbBids.user_id = '. Auth::user()->id))
->where("dbQuotes.active", "=", "1")
->select("dbQuotes.*", "dbACT.*", "dbBids.*",
(DB::raw('date_format(dbQuotes.posted_date, "%d/%m/%Y %H:%i") as posted_date')),
(DB::raw('date_format(dbOpps.expected_date, "%d/%m/%Y") as expected_date')))
->groupBy("dbQuotes.id")
->orderBy("posted_date", "desc")
->get();
$passinvaluehere = $query->dbQuotes.act_id
$bids = DB::table("dbBids")
->where("quote_id", "=", $passinvaluehere)
->get();
return view('jobs', ['query' => $query,'bids' => $bids]);
}
My query works and the view is established in the correct way if I replace the passed value with a number, i.e "8763". My question is how, within this function, can I pass the value/s of dbQuotes.act_id into this second query?
***UPDATED Code from answer: [error Call to a member function lists() on a non-object]
public function jobs()
{
$query = DB::table("dbQuotes")
->leftJoin("dbACT", "dbQuotes.act_id", "=", "dbACT.ID")
->leftJoin("dbOpps", "dbQuotes.act_id", "=", "dbOpps.contactID")
->leftJoin('dbBids', 'dbQuotes.act_id','=',
DB::raw('dbBids.quote_id AND dbBids.user_id = '. Auth::user()->id))
->where("dbQuotes.active", "=", "1")
->select("dbQuotes.*", "dbACT.*", "dbBids.*",
(DB::raw('date_format(dbQuotes.posted_date, "%d/%m/%Y %H:%i") as posted_date')),
(DB::raw('date_format(dbOpps.expected_date, "%d/%m/%Y") as expected_date')))
->groupBy("dbQuotes.id")
->orderBy("posted_date", "desc")
->get();
$act_id = $query->lists('act_id');
$bids = DB::table("dbBids")
->whereIn("quote_id", $act_id)
->get();
return view('jobs', ['query' => $query,'bids' => $bids]);
}

If you have multiple records (as per the ->get() method) you have two ways: either you loop over the Collection and make a query each iteration (bad) or you create an array of ids and use a whereIn in the second query (better):
$passinvaluehere = $query->lists('act_id');
// https://laravel.com/docs/5.2/queries#retrieving-results
// this creates and array of `act_id` s
$bids = DB::table("dbBids")
->whereIn("quote_id", $passinvaluehere)
->get();
// you now have a Collection of multiple $bids
If you expect only a single records from your first query, you need to change the fetcher method, using first() instead, or else take only the first element of your actual collection, something like first($query) or $query[0]
$query = DB::table("dbQuotes")
....
->first();
$passedvaluehere = $query->act_id;
