Change Wordpress Admin URL

Question

I changed my Wordpress directory structure quite a bit. Here's what I have:

define('WP_SITEURL', 'http://' . $_SERVER['SERVER_NAME'] . '/wordpress');
define('WP_HOME',    'http://' . $_SERVER['SERVER_NAME']);
define('WP_CONTENT_DIR', dirname(__FILE__) . '/content');
define('WP_CONTENT_URL', 'http://' . $_SERVER['SERVER_NAME'] . '/content');

So I have a content directory which contains my Plugins and Themes. And then I have a wordpress directory which contains the core WP files, minus the wp-content folder.

With this new structure, I have to access the WP backend with this URL: http://site.dev/wordpress/wp-admin

Is there a way I can change it so I can just access it like so: http://site.dev/wp-admin

I don't want wordpress to be in the URL. Would this be an htaccess update I need to make, or is there a setting I can use in my wp-config.php file?

Here's an article from wordpress's site.

http://wordpress.org/support/topic/how-to-change-the-admin-url-or-wp-admin-to-secure-login

1. Add constant to wp-config.php

   define('WP_ADMIN_DIR', 'secret-folder');  
   define( 'ADMIN_COOKIE_PATH', SITECOOKIEPATH . WP_ADMIN_DIR);  
   

2. Add below filter to functions.php

   add_filter('site_url',  'wpadmin_filter', 10, 3);  
   
   function wpadmin_filter( $url, $path, $orig_scheme ) {  
       $old  = array( "/(wp-admin)/");  
       $admin_dir = WP_ADMIN_DIR;  
       $new  = array($admin_dir);  
       return preg_replace( $old, $new, $url, 1);  
   }
   

3. Add below line to .htaccess file

   RewriteRule ^secret-folder/(.*) wp-admin/$1?%{QUERY_STRING} [L]

I played around with this and there is a much simpler way to do this all in this one simple function below without having to muck around with anything else (create unnecessary folders, redirects, pages, etc.).

// Simple Query String Login page protection
function example_simple_query_string_protection_for_login_page() {

$QS = '?mySecretString=foobar';
$theRequest = 'http://' . $_SERVER['SERVER_NAME'] . '/' . 'wp-login.php' . '?'. $_SERVER['QUERY_STRING'];

// these are for testing
// echo $theRequest . '<br>';
// echo site_url('/wp-login.php').$QS.'<br>';   

    if ( site_url('/wp-login.php').$QS == $theRequest ) {
        echo 'Query string matches';
    } else {
        header( 'Location: http://' . $_SERVER['SERVER_NAME'] . '/' );
    }
}
add_action('login_head', 'example_simple_query_string_protection_for_login_page');
