How to give user access to specific route when certain conditions are met?

For example let user access

Route::get(view('posts/{id}'),'PostsController@show');

when user has over 100 points in his user->points column.

You can use Middleware for this,In Laravel it is very easy to secure your routes by creating your own middlewares.

The following steps are required to do this:

run command php artisan make:middleware Middlewarename and you'll find your middleware inside app/Http/Middleware/yourcustomemiddleware.php
Register your middleware in app/Http/kernel.php file which you just created
Now implement logic in middleware you just created:

YourMiddlewareClassCode:

/**
 * Handle an incoming request.
 *
 * @param  \Illuminate\Http\Request  $request
 * @param  \Closure  $next
 * @return mixed
 */
public function handle($request, Closure $next)
{
    if (Auth::user()->points >= 100)
    {

        return $next($request);

    }

    return redirect()->back()->with('flash_message','you are not allowed to access this');
}

Attach middleware to your route:

routes/web.php:

Route::get(view('posts/{id}'),'PostsController@show')->middleware('yourcustommiddleware');

All done now your route is secured.

Summary: this statement return $next($request); in middleware will return the route when condition is matched else it will redirect to the previous route.

Note: I don't know your db structure and also this is just an example to show you that what is middleware and how it works and how you can use it.
