将get参数添加到laravel的重定向方法中

Question

I use laravel 5.6

I have GET parameter which I want to pass to redirect function.

Route::get('/about', function () {
   //I want to add param to this redirect function
   return redirect('/en/about');
});

if the route looks like /about?param=123 after redirect the param will be lost. is there way to add parameter to redirect method? as I see this function doesn't include input parameters. the parameter is optional, so it may not be provided. maybe there's way to override this function? or some other solution? all suggestions will be appreciated

UPDATE

is it possible to override the redirect() method ? I think in my case it will be the best solution

Answer 1

You have to get the parameter in the URL and pass it to redirect method in an array

Route::get('/about/{param}', function () {
   return \Redirect::route('/en/about', ['param'=>$param])
});

without having to use named route

Route::get('/about/{param}', function () {
   return redirect('/en/about', ['param'=>$param])
});

For optional parameter

Route::get('/about/{param?}', function ($param = 'my param') {
   return redirect('/en/about', ['param'=>$param])
});
