CodePudding user response：

You need to inspect your $latest object. If $latest doesn't exist OR its year doesn't match this year, then the invoice number is 1. Otherwise, it's $latest->noinvoice 1.

You never mentioned where you store your invoice creation date, so I'll assume you use the default created_at Laravel approach. For this task you should add one more condition to your if statement:

if (!$latest or date('Y', strtotime($latest->created_at)) != $year) {
