有没有办法在 Laravel 中取两个日期之间的数字并与之相减

Question

所以我一直在尝试找到一种方法来 get/take 字段“from”和“to”中两个日期之间的数字（离开 table）然后取那个数字（ex . 它是 7) 并用用户的另一个数字减去它 table a 来自一个名为 leaveBalance 的字段它有一个默认数字 20 所以我想要那个 ( 20 -7) 并且结果被保存在那个特定的用户谁请求休假，在更改后的那个 leaveBalance 字段中，是否也可以添加一个 if 语句来检查日期之间的数字是否大于我们在 leaveBalance 上允许的数字 return一条错误消息

这是请假table

user_id

用户 table 有 leaveBalance 字段，两个 table 没有外键关系 leave 上的 user_id 只存储经过身份验证的用户的 id创建休假时，它仅显示在用户视图中创建的该 ID 的叶子

这是请假控制器

public function create()
     {
        $leaves = Leave::latest()->where('user_id',auth()->user()->id)->paginate(5);
        return view('leave.create',compact('leaves'));
    }
public function store(Request $request)
    {
        $this->validate($request,[
            'from'=>'required',
            'to'=>'required',
            'description'=>'required', 
            'type'=>'required'
            ]);
            $data=$request->all();
            $data['user_id']=auth()->user()->id;
            $data['message']='';
            $data['status']=0;
            $leave =Leave::create($data);
            
            $admins = Admin::all();
            $users = User::where('role_id', 2)->get();

            foreach ($admins as $admins) {
                foreach($users as $users){
                $admins->notify(new LeaveSent($leave));
                $users->notify((new LeaveSent($leave)));
            }
        }
        return redirect()->back()->with('message','Leave Created');

    }

这是请假模型：

{
    use Notifiable;

    protected $guarded=[];
    
    public function user(){
        return $this->belongsTo(User::class,'user_id','id');   
     }
}

这是离开的景色

<div class="card-body">
                    <form method="POST" action="{{route('leaves.store')}}">
                        @csrf

                        <div class="form-group">
                            <label>From Date</label>
                            <div class="col-md-6">
                                <input class="datepicker" type="text" class="form-control @error('from') is-invalid @enderror" name="from" required="">

                                @error('from')
                                    <span class="invalid-feedback" role="alert">
                                        <strong>{{ $message }}</strong>
                                    </span>
                                @enderror
                            </div>
                        </div>

                        <div class="form-group">
                            <label>To Date</label>
                            <div class="col-md-6">
                                <input class="datepicker1" type="text" class="form-control @error('to') is-invalid @enderror" name="to" required="">

我愿意在这方面使用 carbon 我对 carbon 了解不多，但我知道它用于日期等，但因为我使用日期选择器，这可能吗？

Answer 1

您可以使用它来检查是否要了解他休了多少天假，您可以构建函数来执行此操作并返回结果

$from = new DateTime("2020-08-20");
$to = new DateTime("2020-08-28");

$diff = $to->diff($from)->format("%a"); // 8

然后传递给结果，捷豹可以帮你做这件事

Answer 2

这是一个可以开发的想法，这样 ajax 关于选择休假类型的事情就完成了，它 returns 可以休假的天数，然后你可以通过添加这个数字datetimepicker 函数，我希望我已经成功地使我的想法更接近。谢谢。

    public function getUserLeave(Request $request)
{
    if ($request->ajax()) {
        $type = $request->type;
        $user_id = $request->user_id;

        $leaves = Leave::where('user_id', $user_id)->where('type', $type)->where(function ($q) {
            $date = Carbon::now();
            $q->where('from', '<=', date('Y-01-01', strtotime($date))); // 2020-01-01
            $q->where('to', '>=', date('Y-m-d', strtotime($date))); // 2020-08-27
        })->get();

        if (count($leaves) > 0) {
            $dateLeave = array();
            foreach ($leaves as $leave) {
                $leave_from = $leave->from;
                $leave_to = $leave->to;

                $diff = $leave_to->diff($leave_from)->format("%a");
                $dateLeave[] = $diff;

            }

            $dateLeaveSum = array_sum($dateLeave);

            // add type of leave
            $annual_leave = 30;
            $sick_leave  = 5;

            if ($type === 'annual_leave'){
                $value =   ($annual_leave - $dateLeaveSum);
                return response()->json($value);

            }

            if ($type === 'sick_leave'){
                $value =   ($sick_leave - $dateLeaveSum);
                return response()->json($value);

            }

        }
    }
}

Answer 3

例如

public function up()
    {
        Schema::create('types', function (Blueprint $table) {
            $table->id();
            $table->string('name')->unique();
            $table->string('days')->unsigned();
            $table->timestamps();
        });
    }

在 table 叶子添加新列名称 type_id

$table->foreignId('type_id')->nullable()->constrained()->onDelete('cascade');
