【问题描述】：

我有一个date，格式为Y-m-d。如何按月过滤？我用 January = 1, February = 2 等数字指定月份。

public function scopegetmonthleavereport($query,$payroll_employee_id,$month)
{

         $query->join('tbl_payroll_leave_employee_v2','tbl_payroll_leave_schedulev2.payroll_leave_employee_id','=','tbl_payroll_leave_employee_v2.payroll_leave_employee_id')
         ->join("tbl_payroll_employee_basic","tbl_payroll_leave_employee_v2.payroll_employee_id","=","tbl_payroll_employee_basic.payroll_employee_id")
         ->join("tbl_payroll_leave_tempv2","tbl_payroll_leave_employee_v2.payroll_leave_temp_id","=","tbl_payroll_leave_tempv2.payroll_leave_temp_id")
         ->select(DB::raw('tbl_payroll_employee_basic.payroll_employee_id , tbl_payroll_leave_schedulev2.payroll_schedule_leave, tbl_payroll_employee_basic.payroll_employee_display_name, tbl_payroll_leave_schedulev2.payroll_leave_temp_with_pay, tbl_payroll_leave_tempv2.payroll_leave_type_id, tbl_payroll_leave_employee_v2.payroll_leave_employee_id, tbl_payroll_leave_schedulev2.consume, tbl_payroll_leave_employee_v2.payroll_leave_temp_hours, sum(tbl_payroll_leave_schedulev2.consume) as total_leave_consume, (tbl_payroll_leave_employee_v2.payroll_leave_temp_hours - sum(tbl_payroll_leave_schedulev2.consume)) as remaining_leave'))
         ->groupBy('tbl_payroll_leave_employee_v2.payroll_leave_temp_id')
         ->where('tbl_payroll_leave_schedulev2.payroll_leave_schedule_archived',0)
         ->where('tbl_payroll_leave_employee_v2.payroll_employee_id', $payroll_employee_id)
         ->whereBetween('tbl_payroll_leave_schedulev2.payroll_schedule_leave', $date);  //where i want to put the date


    return $query;
}

【问题讨论】：

上帝查询构建器是如此 ugly 但在 SQL 中你会这样做 WHERE MONTH(date_field) = :month 提醒我我必须使用 SQL lexer/parser 构建我的 ORM...
@ArtisticPhoenix 我如何在 laravel bro 中用 eloquent 做到这一点？哈哈
我不知道我不使用 Laravel，但该查询构建器在我看来就像 crap（从可读性的角度来看）。我写 SQL 已经 7 年了，
whereMonth 我是用这条线做的哈哈。谢谢你的线索兄弟
当然，我希望我能直接告诉你。但我使用基础知识，这样看起来总是更干净。我的意思是我得到了 ORM，我已经 regretfully 使用过它们（ Doctrine ），我发现它们对我来说就像一副手铐。

【解决方案1】：

试试like和regex里面的where，使用这样的东西：

->Where('date', 'like', '%-' .$month. '-%')->get();

我没试过。

use Carbon\Carbon;

public function index(){
        date_default_timezone_set('Asia/Kolkata');

        //Total Students
         $total_students = User::where('role_id','2')->count();         

        $today = Carbon::today()->toDateTimeString();
         //dd($today);
          $first_day = date('Y, n, j', strtotime('-1 day', strtotime($today)));
            $second_day = date('Y, n, j', strtotime('-2 day', strtotime($today)));
            $third_day = date('Y, n, j', strtotime('-3 day', strtotime($today)));
            $fourth_day = date('Y, n, j', strtotime('-4 day', strtotime($today)));
            $fifth_day = date('Y, n, j', strtotime('-5 day', strtotime($today)));
            $sixth_day = date('Y, n, j', strtotime('-6 day', strtotime($today)));
            $seventh_day = date('Y, n, j', strtotime('-7 day', strtotime($today)));     

        return view('home',compact('total_students','total_doner','current_day_student','first_day','second_day','third_day','fourth_day','fifth_day'
                ,'sixth_day','seventh_day'));
    }
