這是我的路線：// Edit User InfosRoute::put('/edit/subscriber', 'Admin\UserController@editSubscriber')->name('/edit/subscriber');公小號呼叫：axios.put('/admin/edit/subscriber', { userId: this.userDetails._id, newFirstName: this.tempValueFirstName, newLastName: this.tempValueLastName, newPhone: this.tempValuePhone, newEmail: this.tempValueEmail }).then(({res}) => { console.log(res) }).catch(({err}) => { console.log(err) });控制器中的更新功能：public function editSubscriber() { $validated = request()->validate([ 'userId' => 'required', 'newFirstName' => 'required|string|max:255', 'newLastName' => 'required|string|max:255', 'newEmail' => 'required|string|email|max:255', 'newPhone' => 'nullable' ]); $user = User::find($validated['userId']); $user->first_name = $validated['newFirstName']; $user->last_name = $validated['newLastName']; $user->email = $validated['newEmail']; $user->phones = $validated['newPhone']; $user->name = $validated['newLastName'] . ' ' . $validated['newFirstName']; $user->save();}當我嘗試使用我的更新功能時，更改像我想要的那樣更新，但我得到這個500錯誤：“從空值創(chuàng)建默認對象”。有人有想法嗎？謝謝。

由于您的$user未正確初始化。確保您獲得要更新的記錄。
并在值初始化后始終寫下您在代碼中使用的變量并正確條件。
還要始終使用 try catch 語句來快速調(diào)試您的問題。可能下面的代碼將對您有所幫助。
try {
$validated = request()->validate([
'userId' => 'required',
'newFirstName' => 'required|string|max:255',
'newLastName' => 'required|string|max:255',
'newEmail' => 'required|string|email|max:255',
'newPhone' => 'nullable'
]);
if ($validated->fails()) {
return response($validated);
}else{
if (!blank($user)) {
$user = User::find($validated['userId']);
$user->first_name = $validated['newFirstName'];
$user->last_name = $validated['newLastName'];
$user->email = $validated['newEmail'];
$user->phones = $validated['newPhone'];
$user->name = $validated['newLastName'] . ' ' . $validated['newFirstName'];
$user->save();
}else{
//throw error response.
}
}
} catch (\Exception $ex) {
return response(ExceptionMessage($ex));
}
