How to 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() called from the plugin, it returns [wordpress_install_dir], the root of installation)

thanks for help

Answer 1

To get the plugin directory you can use the Wordpress function plugin_basename($file). So you would use is as follows to extract the folder and filename of the plugin:

$plugin_directory = plugin_basename(__FILE__); 

You can combine this with the URL or the server path of the plugin directory. Therefor you can use the constants WP_PLUGIN_URL to get the plugin directory url or WP_PLUGIN_DIR to get the server path.

Read more about it in the Wordpress codex.

Answer 2

Looking at your own answer @Bog, I think you want;

$plugin_dir_path = dirname(__FILE__);

Answer 3

Try this:

function PluginUrl() {

        //Try to use WP API if possible, introduced in WP 2.6
        if (function_exists('plugins_url')) return trailingslashit(plugins_url(basename(dirname(__FILE__))));

        //Try to find manually... can't work if wp-content was renamed or is redirected
        $path = dirname(__FILE__);
        $path = str_replace("\\","/",$path);
        $path = trailingslashit(get_bloginfo('wpurl')) . trailingslashit(substr($path,strpos($path,"wp-content/")));
        return $path;
    }

echo PluginUrl(); will return the current plugin url.
