php - 表单不提交任何东西

Question

大家好，我是网络开发的新手。我有一个更改密码表单，我正在尝试调用 API，但在此之前，该表单似乎没有提交任何数据。下面是用于检查帖子的表格和支票，但它没有返回任何内容。

<form name="passwordForm" method="post">
<div class="password-form">
     <label>New Password:<span class="small-label"> Please enter at least 8 alphanumeric characters</span></label><input class="changepwd" type="password" name="newPassword1" required=""
      id="newPassword1" placeholder="Password"> <br>
<label>Re-type Password:</label><input class="retypepwd " type="password" name="newPassword2" required="" id="newPassword2" placeholder="Password">

     <button type="submit" value="Change Password" id="changePassword" class="buttonlink">Change
      Password</button>
    </form></div>

<?php 
if(isset($_POST['passwordForm'])){
       echo 'test';
?>
