categories display problem show all categories

My code was a pseudo code .. i dont know what table fields you have. You have to ajust this with you needs for e.g. with a proper catogry id like

PHP Code:

public function get_categories($category_id = false, $order_by = null, $sort = 'DESC', $limit = null, $offset = 0) {
...
 if ($category_name)
 {
 $this->db->where('categories.id', $category_id);
 }
... 


This means, that your categories table as a column name id or in the example before a column named name.
