It's not return false, If update failed

[eluser]Mareshal[/eluser]
UPDATE returns 0 when query has an error or something, can't connect to database

I would try this

Code:

$this->db->update(table, $data);
$update = $this->db->affected_rows();

if($update == 1)
{
    return TRUE;
}
else
{
    return FALSE;
}

and after you should try

Code:

$this->db->last_query();

good luck
