Have you tried echoing out your query with:
Code:
echo $this->db->last_query();
to ensure that the code is proper mysql?
Another way you can do it is using:
Code:
$this->db->query('UPDATE the_table SET the_field = the_field + 1 WHERE [your WHERE clause]');
In my opinion this looks a little cleaner, but thats just my opinion.
