How to return back twice in Laravel?
提问by Arthur Tarasov
In Laravel, there is a function return back();, which returns the user to the previous page. Is it possible to return back();more than once within one function to return the user back twice or several times? I tried
在 Laravel 中，有一个函数return back();，可以将用户返回到上一页。是否可以return back();在一个函数中多次返回用户两次或多次？我试过
public function ....()
{
return back();
return back();
}
but it doesn't seem to work.
但它似乎不起作用。

No, but you could use sessionsystem to save URLs of 2-3-4 pages back. Use Session::facade or session()helper for shorter syntax:
不，但您可以使用会话系统将 2-3-4 页的 URL 保存回来。使用Session::Facade 或session()helper 来缩短语法：
$links = session()->has('links') ? session('links') : [];
$currentLink = request()->path(); // Getting current URI like 'category/books/'
array_unshift($links, $currentLink); // Putting it in the beginning of links array
session(['links' => $links]); // Saving links array to the session
And to use it:
并使用它：
return redirect(session('links')[2]); // Will redirect 2 links back

it works for me Redirect::to($request->request->get('http_referrer'))
这个对我有用 Redirect::to($request->request->get('http_referrer'))
