php - How to use count method with my_model -

i'm trying work jamie rumbelow's my_model , i'm running issue figuring out how can use count method array.

i want count total number of personal unread messages logged user has received.

so going try following call:

$unread_messages = $this->personal_messsages->count_by(); 

however, need pass in user_id of user , integer know if message unread or read.

any ideas on how perform this?

unfortunately, count_by() works off single field & value, not array (unless he's updated). you'll have write own this

have @ link see examples of my_model functions: http://codebyjeff.com/blog/2012/01/using-jamie-rumbelows-my_model

edit: may stand corrected on one: try passing in array('user_id'=>$user_id, 'status'=>1); (adjusted own values), may work
