php提交按钮不起作用“问题是不发送电子邮件”

Question

我的问题不是发送电子邮件，问题是在点击提交后，什么也没有发生，甚至回声不工作，我有一个表格在启动。有一个名为“提交”的按钮，当点击时，在表单中输入的内容应该发送到电子邮件地址。尽管当我单击“提交”时，什么也不会发生。

<?php


  if (isset($_REQUEST['email']))  {

  echo "sadfsdagsdgsdg";
        }

?>

                        <button type="submit"  name="submit" value="submit" class="hvr-sweep-to-right">Submit</button>

                  </div> 
                  </form>

Answer 1

就试着用

<input type="submit" value="Submit" class="hvr-sweep-to-right">

而不是

<button type="submit" name="submit" value="submit" class="hvr-sweep-to-right">Submit</button>
