You should make all of your classes independent of their actual location, so you can move them around easily and maybe reuse them in other projects.
I would create a class that tells the other classes what path or URL to use, let it implement an interface so you can reuse the other classes maybe even in a theme or completely outside of WordPress.
Example for the interface:
interface DirectoryAddress { /** * @return string Dir URL with trailing slash */ public function url(); /** * @return string Dir path with trailing slash */ public function path(); }
The concrete implementation in your plugin could look like this:
class PluginDirectoryAddress implements DirectoryAddress { private $path; private $url; public function __construct( $dirpath ) { $this->url = plugins_url( '/', $dirpath ); $this->path = plugin_dir_path( $dirpath ); } /** * @return string Dir URL with trailing slash */ public function url() { return $this->url; } /** * @return string Dir path without trailing slash */ public function path() { return $this->path; } }
Now you create an instance of that class in your main plugin file:
$address = new PluginDirectoryAddress( __DIR__ );
And all the other classes have just a dependency on the interface in their constructor, like this:
public function __construct( DirectoryAddress $directory ) {}
They are accessing the URL and the path only from the passed instance now.
