我是一个使用CodeIgniter的初学者。我正在使用以下URL“http://localhost/ci/index.php/shopcart”访问控制器，但是我得到了404页面未找到的错误。
控制器代码
<?php
class Cart extends CI_Controller { // Our Cart class extends the Controller class
function Cart()
{
parent::CI_Controller(); // We define the the Controller class is the parent.
}
}
function index()
{
$this->load->model('cart_model'); // Load our cart model for our entire class
$data['products'] = $this->cart_model->retrieve_products(); // Retrieve an array with all products
$data['content'] = 'cart/products'; // Select our view file that will display our products
$this->load->view('index', $data); // Display the page with the above defined content
}
?>
模型代码
<?php
class Cart_model extends Model { // Our Cart_model class extends the Model class
// Function to retrieve an array with all product information
function retrieve_products(){
$query = $this->db->get('products'); // Select the table products
return $query->result_array(); // Return the results in a array.
}
}
路由
$route['default_controller'] = "shopcart";
autoload
$autoload['libraries'] = array('cart' , 'database');
$autoload['helper'] = array('form');
