Question

我的laravel应用程序中有一条带有参数的路由。

Route::get('news/update/{id?}', 'Admin\NewsController@update')->name('news.update');

如何使用参数从刀片视图重定向到路线？

{{ route('news.update', ['id' => $_news['id']]) }}

此代码仅重定向到news/update?id=1

有人有主意吗？

编辑：网站仅基于id参数从数据库返回数据。因此GET方法是可以的。该参数是可选的。

            transactions = transactionList,
            redirect_urls = redirUrls

        // Create a payment using a APIContext  
        return this.payment.Create(apiContext);
    }

尝试一下。另外，更新路由可能应该为{{ route('news.update', $_news['id']) }}

Answer 2

确定要使用get更新吗？

在更新时使用{id}而不是{id?}

Laravel使用参数从刀片重定向
