get() + sum() in one line laravel

Question

My data

invoice|amount|
0001   | 10000|
0001   | 10000|

Now my code on Controller;

$invoices = Invoice::where('user_id', 1)
    ->where('status', 'Paid')
    ->orderBy('datePaid', 'desc')
    ->groupBy('no_invoice')
    ->get()
    ->sum('amount');  return view('invoice', ['invoices' => $invoices]);

I want show all data with get() and sum only field amount like this on my foreach.

invoice|total amount|
0001   | 20000|

Answer 1

You can use selectRaw in your select in query and then use sum(amount) like this

$invoices = Invoice::selectRaw('*, sum(amount) as total')
    ->where('user_id', 1)
    ->where('status', 'Paid')
    ->orderBy('datePaid', 'desc')
    ->groupBy('no_invoice')
    ->get();

Now you can print

foreach($invoices as $invoice){
     echo $invoice->total
}
