我正处于php的学习阶段。请帮助我更新表格。高级谢谢。我有一个表单，用“保存”和“重置”按钮更新任何用户信息。我更新版本号增加的任何信息。但问题是当我不更新任何信息并点击“保存”按钮版本数量增加。它不应该增加。我正在给我的控制器和表单代码....

答案 0 :(得分：0)
如果您不更改表单值，则表示不会将此数据发送给服务器。
此处至少会发出按钮保存，因此这种情况将始终为真：
if(!empty($_POST))
您没有显示整个表单，但我建议字段user_id和cv_type具有值（如果表单包含将被提交的字段，则不会更改或不更改mater值）
$id = $_POST['CvUpload']['user_id'];
$cv_type = $_POST['CvUpload']['cv_type'];
这就是模型$CvUploadmodel = CvUpload::model()->find($criteria);加载和增加version_id
