Laravel: How to get the current url as a view helper with parameters
提问by Fabian
I want to build a link in my view that refers to the same page like that one where its placed on. And I want to be able to give a parameter with.
我想在我的视图中建立一个链接，该链接指向与放置它的页面相同的页面。我希望能够给出一个参数。
For example I want to change languages. I have a route like
例如，我想更改语言。我有一条路线
domain.com/{lang}/xyz
And in my view I want to do something like
在我看来，我想做类似的事情
<a href="{{ URL::action(this, ['lang' => 'en']) }}">EN</a>
So I can easily reload the page but just change the "lang" parameter.
所以我可以轻松地重新加载页面，但只需更改“lang”参数。
Hopefully its understandable. Please try to help me.
希望它是可以理解的。请试着帮助我。
(Another side question: Are there no ressources eg a list of all view helpers in Laravel? where do i know which viewhelpers are available?)
（另一个问题：是否没有资源，例如 Laravel 中所有视图助手的列表？我在哪里知道哪些视图助手可用？）

Use laravel's helper method to use in a view:
使用 laravel 的 helper 方法在视图中使用：
url()->current()
This will get the current URL. If you need to get the current route name,
这将获得当前的URL. 如果您需要获取当前路线名称，
Route::current()->getName()
Now you can use this route name to create your own new URL.
现在您可以使用此路由名称来创建您自己的新 URL。
eg:
例如：
<a href="{{ URL::action(Route::currentRouteName(), ['lang' => 'en']) }}">EN</a>
Your route definition may be something like:
您的路线定义可能类似于：
Route::get('/{lang}/about/', ['as'=>'about_us', 'uses'=>'PagesController@about'])
This will provide you the current URL.
这将为您提供当前的 URL。
But in your case, it's better to use the this package for multi language: https://github.com/mcamara/laravel-localization
但在您的情况下，最好将此包用于多语言：https: //github.com/mcamara/laravel-localization
It's pretty simple and easy to use.
它非常简单且易于使用。
