Function Reference/plugin basename

Description

Gets the path to a plugin file or directory, relative to the plugins directory, without the leading and trailing slashes.

<?php plugin_basename( $file ); ?>

$file

(string) (required) Absolute path to a plugin file or directory within the plugins directory.

Default: None

(string): Path to a plugin file or directory, relative to the plugins directory (without the leading and trailing slashes).

If your plugin file is located at /home/www/wp-content/plugins/my-plugin/my-plugin.php, and you call:

$x = plugin_basename( __FILE__ );

The $x variable will equal to "my-plugin/my-plugin.php".

Uses both the WP_PLUGIN_DIR and WPMU_PLUGIN_DIR constants internally, to test for and strip the plugins directory path from the $file path. Note that the direct usage of WordPress internal constants is not recommended.

plugin_basename() is located in wp-includes/plugin.php.
