php - How can I get the current plugin directory in WordPress?

Question

I need to get the current plugin directory like:

[wordpress_install_dir]/wp-content/plugins/plugin_name

(If getcwd() is called from the plugin, it returns [wordpress_install_dir], the root of installation.)

Answer 1

Use the WordPress core function that's designed specifically for that purpose:

<?php plugin_dir_path( __FILE__ ); ?>

See the Codex documentation here.

You also have

<?php plugin_dir_url( __FILE__ ); ?>

if what you're looking for is a URI as opposed to a server path.

See the Codex documentation here.

IMO, it's always best to use the highest-level method that's available in core, and this is it. It makes your code more future-proof.
