Question

我正在为opencart制作自定义模块，现在我正在尝试在模块安装时创建数据库表。当我安装模块时，它没有给出任何恐怖，模块正在工作，但在DB中不存在表。

一开始，我想使用模型

public function install() {
    $this->load->model('module/collectionfilter');
    $this->model_module_collectionfilter->createCollectionfilter();
 }

但它不起作用，所以我改变了一点，使其最简单

        <?php
    class ControllerModuleCollectionfilter extends Controller {
     private $error = array();

   public function install() {
    $this->db->query("CREATE TABLE IF NOT           EXISTS`".DB_PREFIX."collectionfilter` (
                      `category_id` int(11) NOT NULL,
                      `attr_name` VARCHAR(45) NOT NULL,
                      PRIMARY KEY (`attr_name`)
                      ) ENGINE=MyISAM DEFAULT CHARSET=utf8;");
   }

但它仍无法正常工作，我尝试在phpMyAdmin中使用

  CREATE TABLE IF NOT EXISTS `oc_collectionfilter` (
                      `category_id` int(11) NOT NULL,
                      `attr_name` VARCHAR(45) NOT NULL,
                      PRIMARY KEY (`attr_name`)
                      ) ENGINE=MyISAM DEFAULT CHARSET=utf8;

表创建了，所以我不知道为什么它失败了，somebady可以帮助我？

public function install() {
    //$this->load->model('module/collectionfilter');
    //$this->model_module_collectionfilter->createCollectionfilter();
    $string = "CREATE TABLE IF NOT EXISTS `" . DB_PREFIX . "collectionfilter` (
                      `category_id` int(11) NOT NULL,
                      `attr_name` VARCHAR(45) NOT NULL,
                      PRIMARY KEY (`attr_name`)
                      ) ENGINE=MyISAM DEFAULT CHARSET=utf8;";
    $try = $this->db->query($string);
    echo $try;
}
public function uninstall() {

    $this->load->model('module/collectionfilter');
    $this->model_module_collectionfilter->dropCollectionfilter();
}
public function index() {
    $this->load->language('module/collectionfilter');

    $this->document->setTitle($this->language->get('heading_title'));

    $this->load->model('setting/setting');

    if (($this->request->server['REQUEST_METHOD'] == 'POST') && $this->validate()) {
        $this->model_setting_setting->editSetting('collectionfilter', $this->request->post);

        $this->session->data['success'] = $this->language->get('text_success');

        $this->response->redirect($this->url->link('extension/module', 'token=' . $this->session->data['token'], 'SSL'));
    }

    $data['heading_title'] = $this->language->get('heading_title');

    $data['text_edit'] = $this->language->get('text_edit');
    $data['text_enabled'] = $this->language->get('text_enabled');
    $data['text_disabled'] = $this->language->get('text_disabled');

    $data['entry_status'] = $this->language->get('entry_status');

    $data['button_save'] = $this->language->get('button_save');
    $data['button_cancel'] = $this->language->get('button_cancel');

    if (isset($this->error['warning'])) {
        $data['error_warning'] = $this->error['warning'];
    } else {
        $data['error_warning'] = '';
    }

    $data['breadcrumbs'] = array();

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

    $data['breadcrumbs'][] = array(
        'text' => $this->language->get('text_module'),
        'href' => $this->url->link('extension/module', 'token=' . $this->session->data['token'], 'SSL')
    );

    $data['breadcrumbs'][] = array(
        'text' => $this->language->get('heading_title'),
        'href' => $this->url->link('module/collectionfilter', 'token=' . $this->session->data['token'], 'SSL')
    );

    $data['action'] = $this->url->link('module/collectionfilter', 'token=' . $this->session->data['token'], 'SSL');

    $data['cancel'] = $this->url->link('extension/module', 'token=' . $this->session->data['token'], 'SSL');

    if (isset($this->request->post['collectionfilter_status'])) {
        $data['collectionfilter_status'] = $this->request->post['collectionfilter_status'];
    } else {
        $data['collectionfilter_status'] = $this->config->get('collectionfilter_status');
    }

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

    $this->response->setOutput($this->load->view('module/collectionfilter.tpl', $data));
}

protected function validate() {
    if (!$this->user->hasPermission('modify', 'module/collectionfilter')) {
        $this->error['warning'] = $this->language->get('error_permission');
    }

    return !$this->error;
}
 }

解决了，我是。它是托管和我的合作伙伴，我正在研究旧数据库，并且网站不同。

我刚尝试了你的安装功能，它运行正常并在数据库中创建表。

在隐身窗口中登录phpMyAdmin并检查您的表是否存在。有时phpMyAdmin在您使用其刷新按钮之前不会显示新表。

我无法在自定义模块opencart中使用install（）函数
