Trying to update database with textarea...

for the update stuff you need a third parameter : the id or matching key of the dataset:

PHP Code:

$this->db->update('mytable', $data, "id = 4");
or as array
$this->db->update('mytable', $data, array('id' => $id)); 


Look here at the documentation: http://www.codeigniter.com/userguide3/da...-db-update
