Question

我遇到的问题是当我去http://domain/admin/editpage/"id"时，我找不到404，我无法理解为什么id没有被传递到表单中：

控制器

if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Editsale extends CI_Controller {

function __construct() {
parent::__construct();

}

function index() {
    if(!$this->session->userdata('logged_in')) {
        redirect('admin/home');
    }

        $data['title'] = "Edit Sale Name";
        $data['sales_pages'] = $this->sales_model->getSalesPages();
        $data['cms_pages'] = $this->navigation_model->getCMSPages();
        $id = $this->uri->segment(3); 
                    $data['id'] = $id;
        $this->load->library('form_validation');
        $this->form_validation->set_rules('name', 'Name', 'trim|required');
        $this->form_validation->set_rules('location', 'Location', 'trim|required');
        $this->form_validation->set_rules('bedrooms', 'Bedrooms', 'trim|is_natural');
        $this->form_validation->set_rules('bathrooms', 'Bathrooms', 'trim');
        $this->form_validation->set_rules('condition', 'Condition', 'trim');
        $this->form_validation->set_rules('description', 'Description', 'trim');
        $this->form_validation->set_rules('price', 'Price', 'trim');

        if($this->form_validation->run() === TRUE) {
            $data = array(
            'name' => $this->input->post('name', TRUE),
            'location' => $this->input->post('location', TRUE),
            'bedrooms' => $this->input->post('bedrooms', TRUE),
            'bathrooms' => $this->input->post('bathrooms', TRUE),
            'condition' => $this->input->post('condition', TRUE),
            'description' => $this->input->post('description', TRUE),
            'price' => $this->input->post('price', TRUE)
            );

            $this->sales_model->updateSale($data);

            $data['sales'] = $this->sales_model->getSalesPages();   

            redirect('admin/addsale' , $data);

            $this->session->set_flashdata('success', 'Page Saved'); 
        }else{
            $data['content'] = $this->load->view('admin/editsale', NULL, TRUE);
            $this->load->view('template', $data);
        }


}

}

模型

class Sales_model extends CI_Model
{

function __construct() {
        parent::__construct();
}

function getSalesPages() {

        $query = $this->db->get('sales');
        if($query->num_rows() > 0) return $query->result();

    }

function addSale($data) {

$this->db->insert('sales', $data);
return;
}   

function updateSale($id, $data) {

    $this ->db->where('id', $id);
    $this->db->update('sales', $data);
}
 }

Answer 1

由于您使用的是默认的index方法，因此您需要将其包含在您的uri中：

http://domain/admin/editsale/index/$id

或设定路线：

$route['admin/editsale/(:num)'] = 'admin/editsale/index/$1';

或使用其他方法：

http://domain/admin/editsale/edit/$id

如果你没有通过uri传递任何参数，index段只是默认是可选的。

http://domain/admin/editsale

祝你好运。

Answer 2

您需要添加

$data['id']=$id;

在你的控制器中让它在视图中工作。

未从uri细分中收集$ id
