Just to complete this topic: If you set up your table with primary key and auto increment you can omit the process of manually incrementing the id.

Check out this example

if (!$CI->db->table_exists(db_prefix() . 'my_table_name')) {
    $CI->db->query('CREATE TABLE `' . db_prefix() . "my_table_name` (
  `serviceid` int(11) NOT NULL PRIMARY KEY AUTO_INCREMENT,
  `name` varchar(64) NOT NULL,
  `hash` varchar(32) NOT NULL,
  `url` varchar(120) NOT NULL,
  `datecreated` datetime NOT NULL,
  `active` tinyint(1) NOT NULL DEFAULT '1'
) ENGINE=InnoDB DEFAULT CHARSET=" . $CI->db->char_set . ';');

Now you can insert rows

$this->db->insert(db_prefix(). 'my_table_name', [
            'name'         => $data['name'],
            'hash'            => app_generate_hash(),
            'url'     => $data['url'],
            'datecreated'     => date('Y-m-d H:i:s'),
            'active'          => $data['active']
        ]);
