How redirect()->route('home') work?

posted 9 years ago

Hello everyone, can you explain me how redirect()->route('home') works while redirect() return an instance of RedirectResponse and there is no route() function in RedirectResponse class.

I found that redirect is a function in helpers.php

 function redirect($to = null, $status = 302, $headers = [], $secure = null)
    {
        if (is_null($to)) {
            return app('redirect');
        }

        return app('redirect')->to($to, $status, $headers, $secure);
    }
}

and there are two route functions, one in helpers.php

if (!function_exists('route')) {
    /**
     * Generate a URL to a named route.
     *
     * @param  string  $name
     * @param  array   $parameters
     * @param  bool    $absolute
     * @param  \Illuminate\Routing\Route  $route
     * @return string
     */
    function route($name, $parameters = [], $absolute = true, $route = null)
    {
        return app('url')->route($name, $parameters, $absolute, $route);
    }
}

and there is one in Redirector class

    /**
     * Create a new redirect response to a named route.
     *
     * @param  string  $route
     * @param  array   $parameters
     * @param  int     $status
     * @param  array   $headers
     * @return \Illuminate\Http\RedirectResponse
     */
    public function route($route, $parameters = [], $status = 302, $headers = [])
    {
        $path = $this->generator->route($route, $parameters);

        return $this->to($path, $status, $headers);
    }

The helper function returns the URL that belongs to the route with that name. So you can pass the result of that function into the redirect function, which expects a URL.

return redirect(route('home'));

As second parameter of the route() function you can fill route parameters if needed.

Solution

The redirect() function actually don't return a RedirectResponse, it is returning a Illuminate\Routing\Redirector. This class do have the route() method.
