hi, I am trying to use this go get all the subcategories of a certain category jimport('joomla.application.categories'); $categories = new JCategories('com_content'); print_r($categories); $subCategories = $categories->get(78); print_r($subCategories);
but this gives: JCategories Object ( [_nodes:protected] => [_checkedCategories:protected] => [_extension:protected] => c [_table:protected] => c [_field:protected] => c [_key:protected] => c [_statefield:protected] => c [_options:protected] => com_jumi ) subs:
So my guess is I can't acces the nessacary data because it is protected... any help?
