The plugin_dir_url function is used to retrieve the URL of the directory that contains a plugin. This function is useful in cases where you want to use a plugin’s URL in your code. The plugin_dir_url function takes the plugin file path as a parameter, and returns the URL of the plugin directory. The plugin file path can be either absolute or relative.
Here is an example of how to use the plugin_dir_url function:
Suppose you have a plugin named “my-plugin” with the file “my-plugin.php”. The plugin is installed in the “wp-content/plugins/” directory. To get the URL of the plugin directory, you can use the following code:
$plugin_url = plugin_dir_url( __FILE__ );This code will return the URL of the “my-plugin” directory, which will be something like “http://www.example.com/wp-content/plugins/my-plugin/”. You can use this URL in your plugin code to load CSS or JavaScript files, or to link to other pages or resources within your plugin directory.
