Get plugin option in another PHP file

Question

I making a plugin, and I registered several options in the plugin PHP file. So let's consider :

my-plugin/
   - my-plugin.php (options are registered here)
   - admin.php (the admin page of the plugin)
   - parts/
     conf.php (here I try to get options I registered and used in my plugin)

I tried to perform a get_option() in the conf.php file, but it doesn't seem to work : it returns empty. The option is registered and set in the DB (I checked).

I guess I can't access to WP registered options from that file ? How can I achieve that ?

EDIT : I can have a log of the error :

<b>Fatal error</b>:  Call to undefined function get_option() in <b>conf.php</b> on line <b>6</b>

How do you access conf.php? Direct request? Is the file required or included? — tfrommen

I use require_once on a file on the same level. Then this file is loaded in an Ajax way. — enguerranws

But you are in WordPress context, right? Otherwise you'd need to boostrap WordPress. Do you have Debugging turned on? What does var_dump( get_option( 'option_name' ) ) tell you? — tfrommen

I finally included the external PHP file in a Wordpress function in my plugin PHP file.

function get_conf_function(){

  require_once(dirname(__FILE__) ."/parts/conf.php"); 

}

Now, I can access to wp functions when I call that function (with Ajax or not).
