This article will explain in detail the example analysis of the MVC of the CI framework. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

The details are as follows:

The simplest CI model:

Note: the model requires a database

Configuration file in appcation/config.php

We need to use the database here, so we need to fill in the relevant parameters in databases.php. I won't repeat them any more.

Go straight to the topic:

MVC:

1. First talk about the "M" model.

The models in CI are stored in the application/models folder

The naming rule is: class name _ model.php

There is only one class in the file:

Such as:

Class Nb_model extends CI_Model {public function _ construct () {/ / Connect database $this- > load- > database ();} public function get () {/ / query database $query=$this- > db- > get ('users'); / / return query results return $query- > result_array () as an array;}}

2. Secondly, talk about "C"

With the database model and its method, it is time for us to extract the data

The controller in CI is stored in the application/controllers folder

Naming convention: class name .php

Such as:

/ / prevent illegal access to if (! Defined ('BASEPATH') exit (' No direct script access allowed'); class Nb extends CI_Controller {public function _ construct () {parent::__construct (); / load the data model $this- > load- > model ('nb_model');} public function index () {/ / get data according to the data model $data [' nb'] = $this- > nb_model- > get () / / load the view file $this- > load- > view ('nb',$data);}} / / comments at the end of the file / * End of file nb.php * / / * Location:. / application/controllers/nb.php * /

3. Finally, talk about "V"

With the database model and its method, it is time for us to extract the data

The controller in CI is stored in the application/controllers folder

Naming rules: class name .php (of course, it may not be a class name, as long as it matches the name of the parameter passed by view in the controller)

Such as:
