Question

在OpenCart MVC中工作，事情更清楚。由于删除功能现在在技术上有效，因此修改了代码，但是从多个记录列表中删除它总是删除最后一个是我的代码。你选择哪一个并不重要，var _dump总是显示最后一条记录的id。

型号：

public function deleteCampaign($campaign_id) {


    $this->db->query("DELETE FROM `" . DB_PREFIX . "campaigns` WHERE campaign_id = '" . (int)$campaign_id . "'");

    var_dump("DELETE FROM `" . DB_PREFIX . "campaigns` WHERE campaign_id = '" . (int)$campaign_id . "'");
    exit;
    return $campaign_id;
}

控制器：

   public function delete() {
        $this->load->language('campaigns/campaign');

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

        $this->load->model('campaigns/campaign');



        if (isset($this->request->post['campaign_id'])) {
    $campaign_id = $this->request->post['campaign_id'];
    $this->model_campaigns_campaign->deleteCampaign($campaign_id);

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

            $this->response->redirect($this->url->link('campaigns/campaign', 'token=' . $this->session->data['token'] . $url, true));
        }
        $this->getList();
    }

The results of changing hidden to text in the input

Answer 1

第一步：删除记录。

工作原理：

当您单击删除按钮时，将调用javascript函数（changeFormAction）。在提交表单之前，该函数将表单的操作更改为给定的操作名称（“delete”）。给定的操作名称对应于控制器操作。

对于每个广告系列记录，广告系列ID都会保存为删除按钮的value属性的值。提交表单后，其值将在控制器操作delete()中读取，模型方法deleteCampaign()将被调用，并将其作为参数接收。

在HTML中：

将此脚本放在<head>标记中：

<script type="text/javascript">
    /**
     * Change form action dependent of the clicked form button.
     * 
     * @param action string Form action.
     * @return bool
     */
    function changeFormAction(action) {
        var form = document.getElementById('form-order');
        form.action = action;
        return true;
    }
</script>

之后，使用with：

替换dropddown中的最后一个<li>标记

<li class="campaign-dropdown-list">
    <button type="submit" name="deleteButton" value="<?php echo $order['campaign_id']; ?>" onclick="javascript:changeFormAction('<?php echo $delete; ?>');">
        <?php echo $button_delete; ?>
    </button>
</li>

在控制器中：

if (isset($this->request->post['deleteButton']) && $this->validateDelete()) {
    $campaign_id = $this->request->post['deleteButton'];
    $this->model_campaigns_campaign->deleteCampaign($campaign_id);

    //...
}
