Question

Answer 1

It simply like…

Controller :

function foo()
{
    if( ! empty($_POST))
    {
       $hello = serialize($_POST['hello']);
       // You can do your database abstraction here, but is better to have these in your model
       // Btw, by using CI AR, all values are escaped automatically producing safer queries.
       $this->db->insert('some_table', array('hello' => $hello)); 
    }
    else
    {
       // do something
    }
}
