Access URL param from Input::get() with laravel - php

Question

I have a route like this:
Route::get('demo/{system?}', 'MonitorController#demo');
I am using it like so because I would like my url to look like so:
mysite.com/demo/spain-system
Where spain-system will be the variable I need to get.
Right now, I'm getting it like this:
public function demo($systemName = null){
}
But I would like to be able to access to it as if it were a URL parameter with Input::get('system') so I can access to it from other methods or even from other controllers such as BaseController.php.
Is there any way to achieve this?
I've played around with Route::input('system') but then it doesn't work when I pass it as a get parameter (in other Ajax calls and so on)
Update
In PHP we can get URL params by using the $_GET function and laravel provides the function Input::get() to do so as well.
If there were no routes in laravel, I would make use of .htaccess rewrite rules to change this:
mysite.com/demo/?system=spain-system
To this:
mysite.com/demo/spain-system
And I could still retrieve the variable system as a GET parameter by using $_GET["system"].
That's kind of what I would expect of laravel, but it seems it is just treating it as the parameter of the demo method and not really as a URL variable.
Is there any way to keep treating it as a URL variable and at the same time use it in a pretty URL without the ?system= ?

Answer 1

So you actually just want to get an url like this? mysite.com/demo/spain-system instead of mysite.com/demo/?system=spain-system? Laravel provides that by default?
Look, When you want to get the router variable {system?} to be accesible you'll need to do this:
In your router:
Route::get('demo/{system}', 'MonitorController#demo');
Then you have an controller where this noods to stand in:
public function demo($system)
{
//your further system
//You are be able to access the $system variable
echo $system; //just to show the idea of it.
}
When you now go to to localhost/demo/a-system-name/, You'll see a blank page with a-system-name.
Hope this helps, because your question is abit unclear.
