codeigniter

问题 I'm currently working with a CodeIgniter3 application, and have built the basis for a standard blog-like system. The structure is standard CI - User requests a page, page loads controller method, controller method calls any relevant DB functions from its model, and then a view is loaded. However, I'm looking to also make this view accessible via an API. So, instead of the $data array being filled with information to populate into HTML, I would instead pass it to a different view which would

问题 I have this query on my controller: $this->db->select('t1.act_id, t2.login, t1.cust_name, t1.act_type, t1.act_detail, t1.date_added, t1.date_modified, t1.act_notes, ' . 't3.category, t1.total_time, sum(t1.total_time) as total') ->from('activity as t1') ->join('user as t2', 't1.user_id = t2.user_id', 'LEFT') ->join('customer as t3', 't1.cust_name = t3.cust_name', 'LEFT') ->where('t2.login', $user) ->where('MONTH(t1.date_added)', $month) ->order_by('t1.date_added', "desc"); $query = $this->db-

问题 Can somebody explain to me when it's a good practice to use models in CI? An article in wikipedia was referring to CI models as "entirely optional and are rarely needed" is that true in any way? 回答1: Say you needed to call a function called get_user_info that retrieves the users info from a database. You could have a function like this: class Home extends Controller { function __construct() { parent::__construct(); } function index() { $user = $this->get_user_info($_SESSION['user_id']); echo

问题 I'm using codeigniter and the pagination class. This is such a basic question, but I need to make sure I'm not missing something. In order to get the config items necessary to paginate results getting them from a MySQL database it's basically necessary to run the query twice is that right? In other words, you have to run the query to determine the total number of records before you can paginate. So I'm doing it like: Do this query to get number of results $this->db->where('something',
