Question

我试图在laravel中添加忘记密码的功能，当我单击“重置密码”链接时，它显示错误“未定义的变量：标题（视图：）。我已经在控制器中定义了标题，但仍然显示此错误。似乎是传递的数据在视图中不可用，但在忘记的视图中可用。

我的ResetPasswordController.php是

class ResetPasswordController extends Controller
{

    public function __construct()
    {

    }

    public function reset(Request $request) {
        $data['title'] = "Reset";

        return view('auth.passwords.reset',$data);
    }  

}

忘记密码可以正常工作，该密码具有相同的@ layout.app且具有此“ title”变量，但“重置”无效。以下是路线代码

Route::get('/password/forgot', [ 'as' => 'forgot', 'uses' => 'ForgotPasswordController@reset']);
Route::get('/password/reset', [ 'as' => 'reset', 'uses' => 'ResetPasswordController@reset']);

视图为

<html lang="{{ app()->getLocale() }}">
<head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1">

        <main class="py-4">
            <div class="container">
            @yield('content')
            </div>
        </main>
    </div>
</body>
</html>

此功能在“忘记密码”视图中有效，但在“重置密码”视图中出现错误

我也尝试过

$title = "Reset";
    return view('auth.passwords.reset')->with('title', $title);

Answer 1

您必须像这样使用

return view('auth.passwords.reset',compact('data'));

Answer 2

您可以像A.A.Noman的答案一样将变量传递到视图中，否则您可以这样做。

return view('auth.passwords.reset',['data' => $data] );

数据未传递到视图中
