我在將數據插入數據庫并拋出錯誤時遇到了麻煩“count()：參數必須是數組或實現 Countable 的對象”我想在數據庫中添加所有注冊員工的出勤詳細信息控制器 public function Attendence() { $data=employee_data::all(); return view('attendence',compact('data')); } public function mark_attendence(Request $request) { $request->validate([ 'date' => 'required', 'is_present' => 'required' ]); $data=$request->all(); $last_id=employee_data::create($data)->id; if (count($request->is_present) >0 ) { # code... foreach ($return->is_present as $item => $v) { $data2=array( 'is_present' =>$request->is_present[$item], 'date'=> $request->date[$item], 'user_id'=>$last_id ); } //$data2->save(); //$employee->save(); //$employee->employee_data()->create([]); return redirect('/index')->with('succ','Attendence Added Successfully'); }刀片輸出：提交 ID 名字 姓氏 DateOfJoining post Remark @foreach( $data as $row ) {{ $row->id }} {{ $row->first_name }} {{ $row->last_name }} {{ $row- >date_joining }} {{ $row->post }} Present Absent @endforeach Id First Name Last Name DateOfJoining post 備注模型類 employee_attendence 擴展模型 { //protected $fillable = array('is_present' ,'date', 'user_id' );//protected $fillable=[];public $timemstamps= false ;public function employee_data(){ //return $this->hasOne(employee_data::class,'App/employee_data'); return $this->hasOne('App\employee_data');}}

據我所理解。您可能is_present會像name="is_present[]". 如果這是您的情況，那么下面的代碼可以正常工作。如果不是，則不能使用count()if input is not an object or array
public function mark_attendence(Request $request)
{
for($i = 0; $i < sizeof($request->is_present); $i++)
{
$emp = new employee_attendence();
if($request->is_present[$i] == "Present")
$emp->is_present = "Present";
if($request->is_present[$i] == "Absent")
$emp->is_present = "Absent";
$emp->date = now();
$emp->user_id = $request->user_id[$i];
$emp->save();
}
return redirect('/index')->with('succ','Attendence Added Successfully');
}

在你的 Add Attendance 方法中嘗試這個對我有用
for($i = 0; $i < sizeof($request->is_present); $i++)
{
$emp = new employee_attendence();
if($request->is_present[$i] == "Present")
$emp->is_present = "Present";
if($request->is_present[$i] == "Absent")
$emp->is_present = "Absent";
$emp->date = $request->date;
$emp->user_id = $request->user_id[$i];
$emp->save();
}
