Question

我的模型中存在一些问题。我有这个编辑功能，里面是一个foreach，控制更新和插入的地方。我遇到的问题是写入通信表的最后一组else语句。

正在撰写的记录与整体广告系列ID相关联。该id存储在每条记录中。因此，每条记录可能都有自己的communication_id，但它们都具有相同的campaign_id。

因此，目前将WHERE设置为campaign_id会编辑所有记录。我需要在这个实例中使用communication_id但是如何在通信查询之前获取它？假设记录有communication_id 50我想获取该ID然后在WHERE中使用它。我不知道怎么做。

public function editCampaign($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 . "'");

        $parent_id = 0;

        $this->db->query("DELETE FROM " . DB_PREFIX . "campaign_components WHERE campaign_id = '" . (int)$campaign_id . "'");
        //$this->db->query("DELETE FROM " . DB_PREFIX . "communication WHERE campaign_id = '" . (int)$campaign_id . "'");
        foreach($data['component_module'] as $component_data) {

            if ($component_data['component_type'] =='EVENT'){

            if(isset($component_data['component_parent_id'])){
                $parent_id = $component_data['component_parent_id'];

                $this->db->query("UPDATE " . DB_PREFIX . "product SET model = '" . $this->db->escape($component_data['component_type']) . "', date_starting = '" . $this->db->escape($component_data['component_start_date']). "', date_ending = '" . $this->db->escape($data['date_ending']). "', date_added = NOW() WHERE product_id = '" . (int)$parent_id . "'");
                $this->db->query("UPDATE " . DB_PREFIX . "product_description SET name = '" . $this->db->escape($component_data['component_name']) . "', language_id = '1' WHERE product_id ='" . (int)$parent_id . "'");
            }else{

                $this->db->query("INSERT INTO " . DB_PREFIX . "product SET model = '" . $this->db->escape($component_data['component_type']) . "', date_starting = '" . $this->db->escape($data['date_beginning']). "', date_ending = '" . $this->db->escape($data['date_ending']). "', date_added = NOW()");
                $parent_id = $this->db->getLastId();

                $this->db->query("INSERT INTO " . DB_PREFIX . "product_description SET name = '" . $this->db->escape($component_data['component_name']) . "', language_id = '1', product_id ='" . (int)$parent_id . "'");
                $this->db->query("INSERT INTO " . DB_PREFIX . "product_to_category SET category_id = '82', product_id ='" . (int)$parent_id . "' ");

            }

        }else{
            $this->db->query("UPDATE " . DB_PREFIX . "communication SET subject = '" . $this->db->escape($component_data['component_name']) . "', channel = '" . $this->db->escape($component_data['component_type']) . "', status = '" . $this->db->escape($component_data['component_status']) . "'
            , status_date = '" . $this->db->escape($component_data['component_start_date']). "', status = '" . $this->db->escape($component_data['component_status']) . "', created_by = '" . $this->db->escape($component_data['component_owner']) . "', date_added = NOW(), campaign_id = '" . (int)$campaign_id . "'");

        }
            $this->db->query("INSERT INTO " . DB_PREFIX . "campaign_components SET component_name = '" . $this->db->escape($component_data['component_name']) . "', component_type = '" . $this->db->escape($component_data['component_type']) . "', component_status = '" . $this->db->escape($component_data['component_status']) . "'
            , component_owner = '" . $this->db->escape($component_data['component_owner']). "', component_start_date = '" . $this->db->escape($component_data['component_start_date']). "', campaign_id = '" . (int)$campaign_id . "', parent_id = '" . (int)$parent_id . "'");

    }

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

        return $campaign_id;
    }

加入communication表：

UPDATE campaigns AS ca
JOIN communication AS co ON ca.communication_id = co.communication_id
SET ca.col1 = val1, ca.col2 = val2, ...
WHERE co.campaign_id = $campaign_id

（我遗漏了所有PHP变量，因此您可以看到查询的一般结构。）

编辑查询正在写入所有记录
