laravel 5.2 - 检查字段是否为空

Question

我想检查某些字段是否为空。如果为空，则用户可以在不更改当前密码的情况下更新配置文件。如果不为空，则存储密码的新值。我的控制器是：

public function storeUpdatedUser(Request $request)
{
    $this->validate($request, ['email' => 'required', 'name' => 'required', 'surname' => 'required', ]);

    $user = User::findOrFail(Auth::user()->id);
    $user->update($request->all());
    $new_password = false;

    if($new_password != ""){
        $new_password = bcrypt($request->new_password);
        $user->password = $new_password;
    }

    $user->save();
    Session::flash('flash_message', 'User updated!');

    return redirect('/');           
}

但不起作用，如果我输入一些值，密码不会更改图片解释更好

Answer 1

试试这个：

public function storeUpdatedUser(Request $request)
{
    $this->validate($request, ['email' => 'required', 'name' => 'required', 'surname' => 'required', ]);

    $user = User::findOrFail(Auth::user()->id);
    $user->update($request->all());

    if(!empty($request->input('new_password'))) {
        $new_password = bcrypt($request->input('new_password'));
        $user->password = $new_password;
        $user->save();
    }

    Session::flash('flash_message', 'User updated!');

    return redirect('/');           
}

这在 Laravel 5.7 中对我有用：

$user = Auth::user();    
$user->update($request->filled('password') ? $request->all() : $request->except(['password']));

Laravel 检查请求输入是否存在

if($request->has('new_password ')) {
    dd('new_password is exists.');
} else {
    dd('new_password is not exists.');
}

if($request->filled('new_password ')) {
