form validation question

[eluser]dj_voc[/eluser]
I'm just wonder why u leave empty the $post_data array value?

if u want insert some data to db, u should insert the post data to the array value

Code:

$post_data = array(
                'title' => $this->input->post('title'),
                'content' => $this->input->post('content'),
                'user_id' => $some_user_id,
                'posted' => $some_posted,
                'category' => $some_category
            );
