我在php学习阶段。请帮我更新一下表格。先进的谢谢。我有一个表单更新任何用户信息与按钮"保存"answers"重置"按钮。我更新任何信息的版本号增加。但问题是，当我不更新任何信息，点击"保存"按钮，版本号增加。它不应该增加。我给我的控制器和表单代码....

如果你不改变表单值，这并不意味着这些数据不会被发送到服务器。
这里至少button save会被发送，所以这种情况总是为真:
if(!empty($_POST))
你没有显示整个表单，但我建议字段user_id和cv_type有值(无论值在哪里改变或不，如果表单有字段，他们将被提交)
$id = $_POST['CvUpload']['user_id'];
$cv_type = $_POST['CvUpload']['cv_type'];
这就是为什么模型$CvUploadmodel = CvUpload::model()->find($criteria);加载并增加version_id
