Plugin base URL
In a question that is related to, but not the same as, How to link to images in my plugin regardless of the plugin folder's name
plugin-folder/images/containing all images
plugin-folder/classes/containing class definitions
plugin-folder/classes/class1-filescontaining additional files for class 1
plugin-folder/classes/class2-filescontaining additional files for class 2
To access images, I can use relative addressing, such as
plugins_url( '../images/image.png', dirname( __FILE__ ) ) but this requires a knowledge of the file structure, and a level of hard-coding that leads to potential maintenance issues.
Alternatively, I can define a global constant (eg)
define('PLUGIN_ROOT', basename(dirname(__FILE__)) . '/' . basename(__FILE__)); in my main-file.
Ideally, there is a WordPress function that would give me the plugin base name, from anywhere in my plugin (ie always return
/plugin-folder/)… but I haven’t found one. Is there such a beastie?
— EDIT TO ADD —
I am also aware of
plugins_url() with no parameters… but this returns
http://mydomain.ext/wp-content/plugins – ie without my plugin name!
