在whereBetween查询中将laravel中的created_at列转换为ymd格式

Question

this is my controller

public function index(){
    $products = Order::whereHas('user', function ($query) {
    if(request()->has('d') && request()->get('d')){
        $arr = [
           'start' => Carbon::parse(substr(request()->get('d'), 4, 11))->format('Y-m-d'),
           'end' =>  Carbon::parse(substr(request()->get('d'), 64, -44))->format('Y-m-d')
                ];
            $builder = $query->whereBetween('created_at', [$arr['start'],$arr['end']]);
           }
        });
   return OrdersResource::collection($orders->latest()->paginate(5));
    }

my array $arr looks like this

array:2 [
  "start" => "2018-08-07"
  "end" => "2018-08-09"
]

How can i change the created_at (which is a datetime) column in laravel to only Year month day format

I need to convert the created_at to that format in order to perform the whereBetween query of laravel because it didn't give me the exact result

Answer 1

Instead of change the format of the created_at column, I suggest that you should update the start and end to beginning of the first date and the ending of the last date. The Carbon objects should be passed to the whereBetween method instead of their string representation.

$arr = [
   'start' => Carbon::parse(substr(request()->get('d'), 4, 11))->startOfDay(),
   'end' =>  Carbon::parse(substr(request()->get('d'), 64, -44))->endOfDay()
];

// Both `start` and `end` are Carbon objects
$builder = $query->whereBetween('created_at', [$arr['start'],$arr['end']]);

Answer 2

You can used mysql DATE() function

$builder = $query->whereBetween(DB::raw('DATE(created_at)'), [$arr['start'],$arr['end']]);

if you want to change the date format, DATE_FORMAT(created_at, '%Y-%m-%d')

Dont forget to import DB

use DB;
