     }
    $employee->update([

    ]);
}

public function startRow(): int
{
    return 2;
}

    return [

                return $query->where('company_id', Auth::user()->company_id);
            })
        ],
        '*.4' => [

        ],
    ];
}

public function chunkSize(): int
{
    return 1000;
}

public function transformDate($value, $format = 'Y-m-d')
{
    try {
        return \Carbon\Carbon::instance(\PhpOffice\PhpSpreadsheet\Shared\Date::excelToDateTimeObject($value));
    } catch (\ErrorException $e) {
        return \Carbon\Carbon::createFromFormat($format, $value);
    }
}
}

控制器：

public function importEmployee(Request $request)
{
        $validator = Validator::make($request->all(), [
            'document' => 'file|mimes:xls,xlsx|max:5000',
        ]);

        if ($request->hasFile('document'))
        {
            if($validator->passes()) {

                $import = new EmployeeImport;
                $file = $request->file('document');

                $file->move(public_path('storage/employee_imports'), $file->getClientOriginalName());
                Excel::import($import, public_path('storage/employee_imports/' . $file->getClientOriginalName() ));

                return $this->success('Employees Imported.', [
                    'file'         => $file
                ]);
            }else{
                return $this->error($validator->errors(), 422);
            }
        }
}

当我提交时，我得到了这个错误：

[2021-08-19 09:33:40] local.ERROR: Error: Call to undefined function 
App\Imports\create() in 
C:\xampp\htdocs\myapp\app\Imports\EmployeeImport.php:98
Stack trace:

#2

C:\xampp\htdocs\myapp\vendor\laravel\framework\src\Illuminate\Database\Concerns\ManagesTransactions.php(29): Maatwebsite\Excel\Reader->Maatwebsite\Excel{闭包}(对象(Illuminate\Database\MySqlConnection))

这是第 98 行：

$employee = create(Employee::class, $employee_data);

我该如何解决这个问题？

谢谢

Answer 1

更改此行

$employee = create(Employee::class, $employee_data);

到

$employee = Employee::create($employee_data);

create 不是一个单独的函数。检查这个 link https://laravel.com/docs/8.x/eloquent#inserting-and-updating-models
