Update Batch

The general usage of update_batch is like this:

PHP Code:

$data = array(
   array(
      'title' => 'My title' ,
      'name' => 'My Name 2' ,
      'date' => 'My date 2'
   ),
   array(
      'title' => 'Another title' ,
      'name' => 'Another Name 2' ,
      'date' => 'Another date 2'
   )
);

$this->db->update_batch('mytable', $data, 'title'); 


So you need an array in which each element is an array also. The second level contains the condition (produces "WHERE title='My title'") and the field names that must be updated, with the new values for each field.
