Redundant or Safer?

If you use

Code:

$this->validation->whatever_input_name_from_my_form_here;

The values will also be affected by validation rules you specify, such as trim|htmlspecialchars|xss_clean
This gives you more control over sanitizing input.

However, if you're going to use input, it's

Code:

$this->input->post('whatever_input_name_from_my_form_here');

instead of

Code:

$this->input->('whatever_input_name_from_my_form_here');

Finally, even if CI sanitizes a lot of your input, you should still always sanitize input. For instance, if you execute

Code:

$this->db->where('id', $id);
$this->db->delete('mytable');

and $id is empty by mistake, you will delete all records from your table.
