请问我的代码有问题，我使用jquery动态添加输入，我想将此输入的值插入mysql数据库，但错误是 “注意：未定义的索引：年份......” “注意：未定义的索引：月份......”

我无法获得添加输入的值。有我的代码，我无法插入数据库：

答案 0 :(得分：0)

您的值不在表单中。这就是他们提交undefined的原因。

只需将表格包裹在桌子周围，如下所示：

<form method="POST" action="myform.php" >
   <table class="dd" width="100%" id="data">
      <!-- your table content here -->
   </table> 
   <input type="hidden" name="action" value="submit" />
   <input type="submit"  height="20" width="20" value="submit values"/>
</form>

编辑：

这一行应该在表格之前或之后，或者至少在td

中 
<input type="submit" name="addnew" id="addnew" value="addnew"/>

也应该是type="button"，而不是type="submit"。否则，它将提交您的表单，而不是添加新元素。

而且你错过了一个}关闭 if(isset()...)

您的$_POST['extreme']和$_POST['type']必须未定义，因为这些名称没有输入。
