php – 按钮停止发出POST请求

我在这里遇到一个奇怪的问题,我有一段代码,直到昨天工作正常.我的按钮已停止发出POST请求.
下面是示例代码.当我点击按钮btnsubmit时,页面被重定向到view_teacherupdate.PHP,但它没有打印“按钮提交”;

<form  method="post" action="view_teacherUpdate.PHP">
  <input type="submit" name="btnsubmit" value="submit"/>
</form>

view_teacherUpdate.PHP

if(isset($_POST["btnsubmit"]))
{
  echo "button submitted";
}

我启用了error_reporting(E_ALL);但我没有收到任何错误或警告.

会话在两个页面中都启用.

任何帮助,将不胜感激.
提前致谢.

<button id="btnUpdate" name="btnUpdateNew" value="btnUpdateNew"  type="submit" class="btn btn-success">Save</button>

      </form>

您提交的代码包含2个提交按钮(1< button>,1< input type =“submit”>.根据按下的按钮,实际提交了不同的值.我猜这个表单只添加了实际上被点击到POST数据的按钮(或元素类型=提交)(从UI角度来看是有意义的)

根据按下的按钮,我得到了

Array ( [btnsubmit] => Verzenden )

要么

Array ( [btnUpdateNew] => btnUpdateNew )

(“Verzenden”是Send的荷兰语翻译,因为浏览器翻译了这个)

那么,你是不是有机会按错了按钮？

<form  method="post" action="view_teacherUpdate.PHP">
  <input type="submit" name="btnsubmit"/>
  <button id="btnUpdate" name="btnUpdateNew" value="btnUpdateNew" type="submit" class="btn btn-success">Save</button>
</form>
