我在这里遇到一个奇怪的问题，我有一段代码可以正常运行，直到昨天。突然我的按钮停止发出POST请求了。
下面是示例代码。当我单击按钮btnsubmit时，页面被重定向到view_teacherupdate.php，但不打印“按钮已提交”；
<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";
}
我已启用
error_reporting(E_ALL);，但没有收到任何错误或警告。在两个页面中都启用了 session 。
任何帮助，将不胜感激。
提前致谢。

最佳答案
您提交的代码包含2个提交按钮(1个，1个。根据所按下的按钮，实际上会提交一个不同的值。我猜该表单仅添加了按钮(或元素)实际上是单击到POST数据的type = submit(从UI角度来看很有意义)
根据所按下的按钮，我要么
Array ( [btnsubmit] => Verzenden )
或者
Array ( [btnUpdateNew] => btnUpdateNew )
(“Verzenden”是Send的荷兰语翻译，因为浏览器将其翻译为)
那么，可能是您偶然按下了错误的按钮吗？
<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>
