我最近试用了 opencart，所以我是新手。我设法获取数据并将它们显示在 html 表中，但是当我单击列时，我陷入了表的排序。地址栏中的url确实正确显示了路由，指示了数据的ASC和DESC顺序，但是数据中的记录根本没有排序。我哪里做错了？是我的模型还是 Controller ？谢谢

Controller :

<?php

    class ControllerPingPing extends Controller {
        private $error = array();

        public function index() {

            $this->load->language('ping/ping');
            $this->document->setTitle($this->language->get('heading_title'));
            $this->load->model('ping/ping');

            if (isset($this->request->get['sort'])) {
                $sort = $this->request->get['sort'];
            } else {
                $sort = 'e.event_id';
            }
            if (isset($this->request->get['order'])) {
                $order = $this->request->get['order'];
            } else {
                $order = 'ASC';
            }

            $url = '';
            if (isset($this->request->get['sort'])) {
                $url .= '&sort=' . $this->request->get['sort'];
            }
            if (isset($this->request->get['order'])) {
                $url .= '&order=' . $this->request->get['order'];
            }

            //getting all event records
            $filter_data = array();
            $results = $this->model_ping_ping->getEvents($filter_data);
            $url = '';
            foreach ($results as $result) {
                //display event details

                    'event_id'      => $result['event_id'],
                    'code'          => $result['code'],
                    'status'        => $result['status']
                );
            }
            // echo "<pre>";
            // print_r($data['events']);
            // echo "</pre>";
            $data['breadcrumbs'] = array();

            $data['breadcrumbs'][] = array(
                'text' => $this->language->get('text_home'),
                'href' => $this->url->link('common/dashboard', 'user_token=' . $this->session->data['user_token'], true)
            );

            $data['breadcrumbs'][] = array(
                'text' => $this->language->get('heading_title'),
                'href' => $this->url->link('ping/ping', 'user_token=' . $this->session->data['user_token'] . $url, true)
            );

            if ($order == 'ASC') {
                $url .= '&order=DESC';
            } else {
                $url .= '&order=ASC';
            }

            $data['sort_id'] = $this->url->link('ping/ping', 'user_token=' . $this->session->data['user_token'] . '&sort=e.event_id' . $url, true);
            $data['sort_code'] = $this->url->link('ping/ping', 'user_token=' . $this->session->data['user_token'] . '&sort=e.code' . $url, true);

            $url = '';
            if (isset($this->request->get['sort'])) {
                $url .= '&sort=' . $this->request->get['sort'];
            }
            if (isset($this->request->get['order'])) {
                $url .= '&order=' . $this->request->get['order'];
            }

            $data['header'] = $this->load->controller('common/header');
            $data['column_left'] = $this->load->controller('common/column_left');
            $data['footer'] = $this->load->controller('common/footer');

            $data['sort'] = $sort;
            $data['order'] = $order;

            $this->response->setOutput($this->load->view('common/pingTest',$data));
        }
    }

型号:

    class ModelPingPing extends Model {
        public function getEvents($data = array()) {
            $sql = "SELECT * FROM " . DB_PREFIX . "event e";
            $query = $this->db->query($sql);
            return $query->rows;

            // if (!empty($data['filter_name'])) {
            //  $sql .= " AND e.event_id LIKE '" . $this->db->escape($data['filter_name']) . "%'";
            // }

            $sort_data = array(
                'e.event_id',
                'e.code'
            );

            if (isset($data['sort']) && in_array($data['sort'], $sort_data)) {
                $sql .= " ORDER BY " . $data['sort'];
            } else {
                $sql .= " ORDER BY e.event_id";
            }

            if (isset($data['order']) && ($data['order'] == 'DESC')) {
                $sql .= " DESC";
            } else {

最佳答案

我已经找到了答案，我需要在 Controller 中添加这几行代码:

$filter_data = array(
    'sort' => $sort,
    'order' => $order
);

关于php - Opencart 表格列无法排序，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/56575331/
