How to pass a variable in join query in Laravel - sql

Question

I have a variable that I would like to pass in a joined RAW query. How can I do that ?
$current_user_id = Auth::user()->id;
$query = DB::table('users as u')
->selectRaw('
ROW_NUMBER() OVER (ORDER BY u.id) AS No,
u.id,
u.username,
l.level AS Rank
')
->leftjoin(DB::raw('(
SELECT
u.id as ts_user_id,
u.username as ts_username,
u.email as ts_email,
l.downline_user_id AS ts_downline_user_id ,
outer_u.username AS ts_downline_username,
sum(o.pay_amount) AS ts_team_sales
FROM
users as u
INNER JOIN user_levels AS l
ON l.upline_user_id = u.id
INNER JOIN users as outer_u
ON outer_u.id = l.downline_user_id
LEFT JOIN user_levels as downline_level
ON l.downline_user_id = downline_level.upline_user_id
INNER JOIN users as outerdownline__u
ON outerdownline__u.id = downline_level.downline_user_id
LEFT JOIN orders as o
ON o.user_id = downline_level.downline_user_id
WHERE o.status = 1 AND downline_level.level > 1 AND u.id=1 **//HOW to pass the $current_user_id variable here**
GROUP BY l.downline_user_id
)RESULT_TEAM_SALES') , 'RESULT_TEAM_SALES.ts_downline_user_id' , 'l.downline_user_id')
->where('u.id' , $current_user_id)
->groupBy('l.downline_user_id')
->get()
I would like to replace Where u.id = $current_user_id . Is passing the variable possible ?
Please advise.
Thank you.

Do something like
DB::table('users')
->join('contacts', function ($join) {
$join->on('users.column', '=', $yourVariable);
})
->get();

So, this is how I solved it. I made a sub query
$current_user_id = Auth::user()->id;
$teamSales= DB::table('users as u')
->selectRaw('
u.id,
u.username as ts_username,
l.downline_user_id AS ts_downline_user_id ,
outer_u.username AS ts_downline_username,
sum(o.pay_amount) AS ts_team_sales
')
->join('user_levels as l' , 'u.id' , '=' , 'l.upline_user_id')
->join('users as outer_u' , 'outer_u.id' , '=' , 'l.downline_user_id')
->leftJoin('user_levels as downline_level' , 'l.downline_user_id' , '=' , 'downline_level.upline_user_id')
->leftJoin('orders as o' , 'o.user_id' , '=' , 'downline_level.downline_user_id')
->where('o.status' , '=' , 1)
->where('downline_level.level' , '>' , 1)
->where('u.id' , '=' , $current_user_id)
->groupBy('l.downline_user_id')
;
Then used leftJoinSub method to left join the sub query
$query = DB::table('users as u')
->selectRaw('
ROW_NUMBER() OVER (ORDER BY u.id) AS No,
u.id,
u.username,
team_sales.ts_team_sales
')
->join('user_levels as l' , 'l.upline_user_id' , '=' , 'u.id')
->leftJoinSub($teamSales , 'team_sales' , function($join) {
$join->on('l.downline_user_id', '=', 'team_sales.ts_downline_user_id');
})
->where('u.id' , $current_user_id)
->groupBy('l.downline_user_id')
->get();
