opencart中签出页面中的自定义字段

我是opencart和php的新手。我试图用opencart建立一个在线商店。 我正在尝试在签出页面中添加自定义字段。 我使用的是OC1.5.4。 下面是我写的vqmod。问题是该表没有得到更新

请帮帮我，我哪里做错了

签出中的自定义字段

尝试的步骤：


通过在浏览器中调用检查是否安装了vqmod。如果未安装，请向上滚动并阅读步骤
验证文件名和路径，并确认所述文件中存在搜索标记中的代码
检查文件夹权限。确保vqmod/vqcache和vqmod/logs具有755或777权限。如果什么都不起作用，则递归尝试vqmod文件夹的777权限
检查vqmod/logs中的错误日志
检查已安装的vqmod版本和xml文件（）中给出的vqmod版本，两者都需要相同
删除vqmod/vqcache中的文件并再次检查。还要查看是否生成了文件的vqmod副本。
将任何vqmod xml文件移到vqmod文件夹之外并检查。如果一切正常，请将xml移回vqmod文件夹。我不知道原因，但它在某些情况下对我有效：）
–将这一行放在XML的顶部，使其有效且更兼容
尝试VQMod管理器扩展。它可能会帮助你

参考链接：回答得很晚，但将来可能会帮助其他人：
末尾缺少一个
：

<input type="text" name="selection" value="<?php echo $selection; ?>" 
  id="selection"? 

添加的新字段是否显示在前端？验证有效吗？是的。。。它将显示在前端。。。我可以在该字段中输入值。。。也可以处理订单。。。我在订单表中添加了名为“selection”的额外字段。。。但我无法在数据库中看到该值。您是否检查了错误日志？而不是替换
$this->db->query（“插入到
..”）`在订单模型中，我建议在插入订单并检索新的
$Order\u id
后添加更新查询。无论如何，我在您的vQmod中没有发现任何问题，因此只有日志（vQmod或PHP错误）应该会显示问题。您确定DB字段
选择
的类型为string（VARCHAR，CHAR，TEXT）？因为您正试图在其中存储字符串值。。。
<input type="text" name="selection" value="<?php echo $selection; ?>" 
  id="selection"? >
