所以我一直在试图找到一种方法来获取/获取字段中两个日期之间的数字"从"；以及"；至"；(leavetable(然后取这个数字(例如，它是7(，并用用户表中的另一个数字减去一个名为leaveBalance的字段a，它的默认数字是20，所以我希望(20-7(和结果保存在请求休假的特定用户中，在更改后的leaveBalancefield中，还可以添加一个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，以返回错误消息吗
这是左表
- id
- user_id
- 来自
- 至
- 类型
- 说明
- 状态
- 消息
用户表有leaveBalance字段，并且这两个表没有外键关系-休假上的user_id只存储创建休假时已验证用户的id，然后它只显示用户视图上创建的id的叶子
这是请假管理员
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');
}
这是休假模式：
{
use Notifiable;
protected $guarded=[];
public function user(){
return $this->belongsTo(User::class,'user_id','id');
}
}
这是Leave 的观点

我对在这方面使用碳持开放态度，我对碳的了解不多，但我知道它是用于日期之类的，但既然我使用了日期选择器，这可能吗？
您可以使用它来检查是否要了解他休假了多少天，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
然后把它传递给结果，美洲虎可以帮助你完成

这是一个可以开发的想法，这样就可以完成关于选择休假类型的ajax，并返回假期的可用天数，然后您可以通过datetimepicker函数添加这个数字，我希望我已经成功地实现了我的想法。非常感谢。
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);
}
}
}
}
例如
public function up()
{
Schema::create('types', function (Blueprint $table) {
$table->id();
$table->string('name')->unique();
$table->string('days')->unsigned();
$table->timestamps();
});
}
在表格左侧添加新列名type_id
$table->foreignId('type_id')->nullable()->constrained()->onDelete('cascade');
