Question

我正在设置页面上，用户在输入字段中看到其预填的用户名和电子邮件。我喜欢检测（没有jQuery）用户是否更改了输入中的预填充值。

对于密码重置字段（未预填写），我使用以下逻辑：

if($request['password'] != ""){
    if(!(Hash::check($request['password'], Auth::user()->password))){
      return redirect()->back()->with('error', 'Your password does not match with the password you provided.');
    }

    if(strcmp($request['password'], $request['new_password']) == 0){
      return redirect()->back()->with('error', 'New password cannot be same as your old one.');
    }

    $validation = $request->validate([
      'password' => 'required',
      'new_password' => 'required|string|min:6|confirmed',
    ]);

    $user->password = bcrypt($request['new_password']);
    $user->save();

    return redirect()->back()->with('alert-success', 'Password changed 
     successfully');
}

我如何检查用户是否更改了预填充代码以使用以下过程：

if($request[''] ????? ""){
    $user = Auth::user();
    $user->name = $request['name'];
    $user->email = $request['email'];
    $user->save();
}

谢谢

我认为，您不需要所有这些。只需使用以下内容。如果值更改，它只会真正更新模型。如果值没有更改（即，提交的数据与数据库中已存储的数据相同），则不会进行数据库查询。

$user = Auth::user();
$user->fill($request->only(['name', 'email']));
$user->save();

经过长时间搜索，我发现isDirty()检查数据库信息是否已更改，但是在发送之前我需要检查预填充的输入是否已更改，因此我添加了第二个操作按钮，现在使用switch语句获取更多信息。控制行为，例如：

public function profilePost(UserUpdate $request)
{

  switch($request->input('action')){
    case 'save_user':
      $user = Auth::user();
      $user->name = $request['name'];
      $user->email = $request['email'];
      $user->save();

      return redirect()->back()->with('alert-success', 'Your profile information changed successfully');

      break;

    case 'save_password':
      if($request['password'] != ""){
        if(!(Hash::check($request['password'], Auth::user()->password))){
          return redirect()->back()->with('error', 'Your current password does not match with the password you provided.');
        }

        if(strcmp($request['password'], $request['new_password']) == 0){
          return redirect()->back()->with('error', 'New password cannot be same as your current one.');
        }

        $validation = $request->validate([
            'password' => 'required',
            'new_password' => 'required|string|min:6|confirmed'
        ]);

        $user = Auth::user();
        $user->password = bcrypt($request['new_password']);
        $user->save();

        return redirect()->back()->with('alert-success', 'Password changed 
         successfully');
      } else {
        return redirect()->back()->with('error', 'No Password was changed');
      }
      break;
  }
}
