在收集過濾器方法中使用 where 條件 - Laravel

Question

如果它的屬性值低於當前月份，我有一個要過濾的集合。 為此，我在集合過濾器方法中使用 whereBetween 方法，但它不過濾任何項目並按原樣返回整個集合。

我正在使用 Laravel 5.8

這是我的代碼

碳日期

public $c_som, $c_eom

$this->c_som = Carbon::now('Asia/Kolkata')->startOfMonth();
$this->c_eom = Carbon::now('Asia/Kolkata')->endOfMonth();

        {

            "doj": "2019-11-16",

            "claw_back_date": "2019-10-25"
        }
]

過濾方法

$cm_revenue_data = $revenue_data->filter(function ($item) {

            return $item
                ->whereBetween('doj', [$this->c_som, $this->c_eom]);
                ->orWhereBetween('claw_back_date', [$this->c_som, $this->c_eom]);
        });

Answer 1

我認為使用whereBetween()不太正確，因為這些屬性是string ，而som和eom是Carbon的實例。

如果您想從集合中獲取doj或claw_back_date為當前月份的項目，則只需通過首先將string轉換為Carbon實例來比較該屬性。

        $array = [
            [
                'doj' => '2019-11-16',
                'claw_back_date' => '2019-10-25',
            ],
            [
                'doj' => '2019-10-10',
                'claw_back_date' => '2019-11-13',
            ],
            [
                'doj' => '2019-06-18',
                'claw_back_date' => '2019-10-25',
            ],
        ];


        $now = Carbon::now();

        $collection = collect($array)->filter(function ($item) use ($now) {
            if (Carbon::createFromFormat('Y-m-d', $item['doj'])->month === $now->month) {
                return true;
            }

            if (Carbon::createFromFormat('Y-m-d', $item['claw_back_date'])->month === $now->month) {
                return true;
            }

            return false;

        });
