Laravel 5：通过数据透视同步额外的字段

您实际上非常接近。所需格式为：

[    98 => ['company_id' => 129],    99 => ['company_id' => 130],    100 => ['company_id' => 131]]

这应该生成正确的数组：

$extra = array_map(function($companyId){    return ['company_id' => $companyId];}, $allCompanyIds);$data = array_combine($allPositionIds, $extra);$user->positions()->sync($data);
