How to send notification to users when approached expiration time (yearly)

Question

I have an invoice model. I trying if approached expiration time send notification to users but I don't know how does it.

My table:

| service_name | start_date(date) | notification_at(date) |
|:-------------|-----------------:|:---------------------:|
| example      | 2018-08-01       |         NULL          |

I want to 30 days before every year send notification to user if specified start_date is set a date. So send notification when now is 2019-07-1 .How I can checking every day with schedule in Laravel ?

I tried case:

Invoice::whereNotNull('start_date')->whereDate('start_date','....');

SOLVED

Actually, the scenarios I wanted to do were these. For examples,

• It should be first send notification date is 2019-07-01 (30 days before every year)

• It should be second send notification date is 2019-07-15 (15 days before every year)

• It should be third send notification date is 2019-07-26 (5 days before every year)

• And always should be repeat these steps as next year

I found the solution like this. Firstly, I did modified My Table like this.

| service_name | start_date(date) | next_notification_date(date) | next_add_day(int) |
|:-------------|-----------------:|:----------------------------:|:-----------------:|
| example      | 2018-08-01       |             NULL             |        NULL       |

And I create a command class to the process.

ExpirationCommand.php

public function handle()
{
        $now = Carbon::now();

        Invoice::whereNotNull('start_date')->whereDate('next_notification_date', $now->format('Y-m-d'))->each(function ($invoice) use ($now) {
            // defines
            $addDay = $invoice->next_add_day;
            $addYear = 365 - 30 - 15 - 5;

            // send notification
            event(new ExpirationInvoiceEvent($invoice->project,$invoice->next_notification_date->diffInDays($now)));

            // setup db
            if ( ! $addDay || $addDay === $addYear) {
                $addDay = 30;
            } elseif ($addDay !== 15 && $addDay !== 5) {
                $addDay = 15;
            } elseif ($addDay !== 5) {
                $addDay = 5;
            } else {
                $addDay = $addYear;
            }

            $invoice->update([
                'next_notification_date' => $now->addDay($addDay)->format('Y-m-d'),
                'next_add_day'           => $addDay,
            ]);
        });
}

And finally I add command in the Console\\Kernel.php for control twice in day

$schedule->command('expiration-control')->twiceDaily();
