Say we have this function
public function addAdditionalEditorFiles(string $param)
{
// do something
}
Now in order to enqueue files to the Wordpress Admin area, we need to utilise an add_action call, however these normally only allow for usage without parameters. e.g.
add_action('enqueue_block_editor_assets', [$this, 'loadAdditionalEditorFiles']);
So how do we pass a custom parameter to this function call? Using Closures.
$param = 'something';
add_action('enqueue_block_editor_assets', function() use ($param) {
$this->loadAdditionalEditorFiles($param);
});
