How is this value failing my laravel date validation?

Question

So I am posting to an api controller action, as we can see I have some basic validation:

public function store(Request $request) {
        $fields = $request->except(['_token']);
        $user   = $request->user();

        $request->validate([
            'log_date' => 'required|date_format:"Y-m-d"',
            'bill_time' => 'required|numeric',
        ]);
}

I constantly get: The log date does not match the format Y-m-d.

The date coming in is formatted by moment js and shows:

"2018-11-6"

So I am confused how is that not formatted properly?

Answer 1

When using Y-m-d, the d on that format mask applies the following:

Day of the month, 2 digits with leading zeros

So, the value being passed 2018-11-6 fails due to 6 not matching 06. Either use Y-m-j, where j is

Day of the month without leading zeros

Or adjust how moment is sending your value.
