Wordpress get plugin directory

Question

Is there any function that would return the full path of my plugin in WordPress?

Example is

path/wp-contents/plugins/myplugin

I have tried plugin_dir_path(__FILE__) but returns the current dir.

Answer 1

Code For Plugin Root Path

$dir = plugin_dir_path( __FILE__ );

// Example: /home/user/var/www/wordpress/wp-content/plugins/my-plugin/

Code for plugin path

echo  WP_PLUGIN_DIR.'/plugin-name';

Answer 2

I will suggest following code. if you are accessing this function from any subfolder.

plugins_url( 'images/logo.png' , dirname(__FILE__ ));
