In a nutshell, my question is "How do I convert the absolute path of the executing script, e.g.,




to the absolute URL?"




I don't even need the actual script name, just the path up to directory it's in.


I've created a class that greatly simplifies creating an option page for a plugin. It doesn't (yet) do the heavy-lifting of registering/adding options via the Settings API, it's more a helper class that

  • creates the menu item (add_menu_page or add_submenu_page)
  • creates a plugin action link in the plugins listing page (plugin.php)
  • displays a custom icon in the menu (if a top-level menu item)
  • injects stylesheets and/or javascript files in the head - the WP way (register/enqueue)
  • a few other misc. things related to creating an option page

It does these things with a minimal number of options passed in the instantiation of the class.


I created this class with only plugins in mind, but realized it works out of the box for themes, too...except in regards to generating URLs from relative references. Right now, I use

$my_url = plugins_url('/', __FILE__)

to generate URLs for stylesheets, script files (.js), and the menu icon file that are associated with the option page only if the user enters a relative URL. If they enter an absolute URL, I don't touch it. Example: if you include 'icon_url' => 'images/my-icon.png' as an option, the class would convert that to


But since I've decided to make this class work for themes as well, I've realized I can't use plugins_url. I'm trying to stay away (if possible) from forcing the user to specify whether this class is going to be used for a plugin or a theme.

Is there a WordPress way similar to plugins_url() that I could use?

Call get_stylesheet_directory_uri() for the current theme, or get_template_directory_uri() for the parent theme of a child theme, and append your file paths to that.

$url = get_stylesheet_directory_uri() . '/images/my-icon.png';
$url = get_template_directory_uri() . '/images/my-icon.png';

Edit: To determine whether you're in a plugin, a parent theme or a child theme, compare the folder you're in (via dirname(__FILE__)) to plugin_dir_path(), get_template_directory() and get_stylesheet_directory() respectively.

Thanks, webaware, but that would require me to have the user specify that this was a theme instead of a plugin, something I'm trying to figure out programmatically. I'm trying to find a WordPress-centric way to get the URL from the absolute path if it's possible. – akTed Jan 12 '13 at 6:16
I can't see how you'd handle that, other than perhaps comparing dirname(__FILE__) to WP_PLUGIN_DIR (for plugins). – webaware Jan 12 '13 at 6:20
After more research, it's looking more and more like I'll have to take that route (comparing __FILE__ to the plugin & theme directories). I plan on leaving this question open for 24 hours unless a slam-dunk answer comes along (doubtful). You should put your suggestion as an answer and I'll choose it, if no better answers come along. – akTed Jan 12 '13 at 9:01

In your wp-config.php file, at the very end it should define ABSPATH to be the wp root folder. You can then replace that from your filepath with site_url (or, if you've instead checked the path for theme/plugin/upload directory, then the appropriate url-function listed at https://codex.wordpress.org/Function_Reference/plugin_dir_url#Related)
