Answer 1

CodeIgniter returns result rows as objects, not arrays. So you need to access it using -> . Like instead of $post['ctgparent_name']; use $post->ctgparent_name.

Answer 2

This happens if you're trying to access properties of an object with $object['property'] notation instead you have to use $object->property.In your case you're doing $post['ctgparent_name'] and echo $post['ctgparent_description'] and you can change those to $post->ctgparent_name and $post->ctgparent_description respectively.

There is another solution if you're using codeigniter active records to fetch data from the database (as I suspect you do). If you're using $query->result() method, this will give you an object. You can use $query->result_array() instead so you now have an array of results you can play with $array['whatever'] notation.

Further, if you're using PDO or mysqli there are methods to get database result sets as an array. Refer the official documentation PDO result array, Mysql result array or Mysql associative array.
