$this->db->update_batch();

Generates an update string based on the data you supply, and runs the query. You can either pass an +array or an object to the function. Here is an example using an array:

The first parameter will contain the table name, the second is an associative array of values, the third parameter is the where key.

Note: All values are escaped automatically producing safer queries.
