Previous route name in Laravel 5.1-5.6

Question

I try to find name of previous route in Laravel 5.1. With:

{!! URL::previous() !!}

I get the route url, but I try to get route name like I get for current page:

{!! Route::current()->getName() !!}

My client wont a different text for Thank you page, depends on from page (Register page or Contact page) user go to Thank you page. I try with:

{!! Route::previous()->getName() !!}

But that didn't work. I try to get something like:

@if(previous-route == 'contact')
  some text
@else
  other text
@endif

Here what work for me. I find this answer and this question and modify it to work in my case: https://stackoverflow.com/a/36476224/2807381

@if(app('router')->getRoutes()->match(app('request')->create(URL::previous()))->getName() == 'public.contact')
    Some text
@endif

Answer 2

I've created a helper function like this.

/**
 * Return whether previous route name is equal to a given route name.
 *
 * @param string $routeName
 * @return boolean
 */
function is_previous_route(string $routeName) : bool
{
    $previousRequest = app('request')->create(URL::previous());

    try {
        $previousRouteName = app('router')->getRoutes()->match($previousRequest)->getName();
    } catch (\Symfony\Component\HttpKernel\Exception\NotFoundHttpException $exception) {
        // Exception is thrown if no mathing route found.
        // This will happen for example when comming from outside of this app.
        return false;
    }

    return $previousRouteName === $routeName;
}

You can't get route name of previous page, so your options are:

1. Check previous URL instead of a route name.

2. Use sessions. First, save route name:

   session()->flash('previous-route', Route::current()->getName());
   

Then check if session has previous-route:

@if (session()->has(`previous-route`) && session(`previous-route`) == 'contacts')
    Display something
@endif

3. Use GET parameters to pass route name.

If I were you, I'd use sessions or would check previous URL.
