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
public function ....()
{
return back();
return back();
}but it doesn't seem to work.
No, but you could use session system to save URLs of 2-3-4 pages back. Use Session:: facade or session() helper for shorter syntax:
$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 sessionAnd to use it:
return redirect(session('links')[2]); // Will redirect 2 links backHi,
i'm not sure how to solve this:
I list all customers (with sorting options via URL query ?sort=...&city...)
I click on "Create new customer"
I save the new customer
I want to redirect to step 1 with a) the same sorting settings AND with the new user (of course only displayed if he fits into the search request).
Inside MyController():
public function saveCustomer()
{
// save data into db
return Redirect::action('MyController@listCustomers');
}
Okay this just redirects to "List all customers" without any sorting :(
Instead of this i tried
return Redirect::back();
but this redirects only to the last page (the new-customer-form).
So i need something like javascript history go back(-2) but with a refresh of that url.
Maybe put the referer into a hidden field inside the form and send it to the saveCustomers controller?
return Redirect::to(Input::get('referer'));
Any other ideas?
Thanks, Sharping
just type this
echo '<script type="text/javascript">'
, 'history.go(-2);'
, '</script>';
I would not rely on JavaScript code as JS may be disabled in a browser. Instead, at step 2 I would put:
Session::flash('url',Request::server('HTTP_REFERER'));
and then at step 4 I would redirect to the URL which is saved in the session variable:
return Redirect::to(Session::get('url'));

Your solution will redirect to second last page but can not load new customer.

This solution is mean When you in step one, you flash session url now and you can get session url after submit new customer
Flash url in YourController@index
Session::flash('backUrl', Request::fullUrl());
Keep the sub session key in YourController@create and YourController@store
if (Session::has('backUrl')) {
Session::keep('backUrl');
}
Consume the session value in YourController@store or any subsequent views
// YourController@store
return ($url = Session::get('backUrl'))
? Redirect::to($url)
: Redirect::route('any.named.route');
// or any views
@if ($url = Session::get('backUrl'))
<a href="$url">Back to List</a>
@endif
Step 1 uses get tokens. Simply save the full URL in a session variable and use it to redirect in step 4. No need to over think it.
