Saving voucher

The 500 Internal Server Error is a very general HTTP status code that means something has gone wrong on the web site's server but the server could not be more specific on what the exact problem is.

So as suggested to you in the past, use your browser developer tools and look at what's going on.

Try now to remember to always do that as a first step. That's how most of us figure this stuff out.

VoucherController.php

public function store(Request $request, Voucher $voucher)
    {
    $validate = $this->voucher_repo->validateType($request);

    if ($validate) {
        $this->voucher_repo->addAction($request, $voucher);
        Session::flash('flash', 'Successfully add voucher');
        
    } else {
        return redirect()
            ->back()
            ->withError('Persentase Voucher tidak boleh lebih dari sama dengan 100%')->withInput();
    }
    return redirect('voucher');
    }

Voucher Repository.php

public function addAction($request, $voucher)
   {
    $user = json_encode($request['user']);
    $startDate = date('Y-m-d', strtotime($request['start_date']));
    $endDate = date('Y-m-d', strtotime($request['end_date']));

    $attr = [
        "voucher_code" => $request['voucher_code'],
        "discount_type" => $request['discount_type'],
        "discount_value" => $request['discount_value'],
        'minimum_payment' => $request['minimum_payment'],
        'quota' => $request['quota'],
        "start_date" => $startDate,
        "end_date" => $endDate,
        "user" => $user
    ];

    $locales = config('locales');

    foreach ($locales as $key => $value) {
        $voucher->translateOrNew($key)->description = $request->description[$key];
    }

    $voucher->fill($attr);
    $voucher->save();
}

laravel.log

This is strange since I do not feel like calling voucher_translations model.

I don't know if there is something to do with the package:

https://packagist.org/packages/dimsav/laravel-translatable

I search the vendor and still do not find the voucher_translation

But your browser tools will show you exactly the request and responses.

What is browser tools? Inspect Element in Firefox? I currectly use laravel.log to spot the error message.

Google: "Firefox browser tools" or "Firefox devtools".
