更改插入查询以更新查询

Question

我在OpenCart MVC中工作，并且即时更新数据库记录时遇到问题。我有一个列表显示数据库表中的所有记录。每个记录都有一个带编辑的下拉菜单作为选项。当单击编辑时，输入的表格被打开，输入内容填入现有值（迄今为止都是好的！），当输入新信息时，用户应该能够点击保存按钮并更新数据库。目前保存按钮查询是一个插入查询。所以我认为它不写，因为它已经有记录。 Id也不是添加一个新按钮（即更新）Id喜欢能够使用现有的保存按钮。如何更改模型以反映这一点？我有插入和更新查询以及某种检查吗？我在控制器上执行此操作吗？我有点困惑如何做到这一点。

MODEL：

public function addCampaign($data) { 

     $this->db->query("INSERT INTO " . DB_PREFIX . "campaigns SET campaign_name = '" . $this->db->escape($data['campaign_name']) . "', campaign_giving_goal = '" . (float)$data['campaign_giving_goal'] 
     . "', code = '" . $this->db->escape($data['code']) . "', campaign_active = '" . $this->db->escape($data['campaign_active']) . "', campaign_giving_count_goal = '" . (float)$data['campaign_giving_count_goal'] . "', campaign_owner = '" . $this->db->escape($data['campaign_owner']). "', date_beginning = '" . $this->db->escape($data['date_beginning']). "', date_ending = '" . $this->db->escape($data['date_ending']). "'"); 

     $this->cache->delete('campaign'); 

     return $campaign_id; 
    } 

控制：

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

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

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

     if (($this->request->server['REQUEST_METHOD'] == 'POST')) { 


      $this->model_campaigns_campaign->addCampaign($this->request->post); 
      $this->model_campaigns_campaign->addComponent($this->request->post); 
      $this->session->data['success'] = $this->language->get('text_success'); 
      $url = '';   

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

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

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

     $this->getForm(); 

    } 

VIEW：

<div class="cancel-save"> 
        <button type="submit" form="form-campaign" data-toggle="tooltip" title="<?php echo $button_save; ?>" class="btn btn-primary" onclick="submitForms()"><i class="fa fa-save"></i></button> 

        <a href="<?php echo $cancel; ?>" data-toggle="tooltip" title="<?php echo $button_cancel; ?>" class="btn btn-default"><i class="fa fa-reply"></i></a> 
       </div>

试试这一个。 在控制器上像这样修改。

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

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

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

    if (($this->request->server['REQUEST_METHOD'] == 'POST')) { 
     if (!isset($this->request->get['campaign_id'])) { 
      $this->model_campaigns_campaign->addCampaign($this->request->post); 
      $this->model_campaigns_campaign->addComponent($this->request->post); 
     } else { 
      $this->model_campaigns_campaign->updateCampaign($this->request->get['campaign_id'], $this->request->post); 
      $this->model_campaigns_campaign->updateComponent($this->request->get['campaign_id'], $this->request->post); 
     } 
     $this->session->data['success'] = $this->language->get('text_success'); 
     $url = '';   

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

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

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

    $this->getForm(); 

} 

然后在模型

public function updateCampaign($campaign_id, $data) { 

    $this->db->query("UPDATE " . DB_PREFIX . "campaigns SET campaign_name = '" . $this->db->escape($data['campaign_name']) . "', campaign_giving_goal = '" . (float)$data['campaign_giving_goal'] 
    . "', code = '" . $this->db->escape($data['code']) . "', campaign_active = '" . $this->db->escape($data['campaign_active']) . "', campaign_giving_count_goal = '" . (float)$data['campaign_giving_count_goal'] . "', campaign_owner = '" . $this->db->escape($data['campaign_owner']). "', date_beginning = '" . $this->db->escape($data['date_beginning']). "', date_ending = '" . $this->db->escape($data['date_ending']). "' WHERE campaign_id = '" . (int)$campaign_id . "'"); 

    $this->cache->delete('campaign'); 
} 

添加此代码，我不能提供updateComponen模型，因为你不写它。也许你可以使用updateCampaign代码作为引用来编写它。
