未提交的WordPress插件表单

Question

我正在开发一个WordPress插件，它有一个表单，我很难让php文件识别表单已经提交了。这个想法是，一旦我点击提交按钮，页面就会重新加载并警告“提交的表单”。

PHP

add_shortcode('show_game_form','ate_form_activate');
function ate_form_activate(){
  if(is_page('Commercial'))
  {

  if(isset( $_POST['ate-final-submi'] ))
    { 
      //NOT ALERTING!!!!!!
      echo "<script type='text/javascript'> alert('Submitted Form'); </script>";
    }
    //Display Page
    $myfile = fopen("/ATE-Form/index.html", "r") or die("Unable to open file!");
    echo fread($myfile,filesize("/ATE-Form/index.html"));
    fclose($myfile);

    return  "";
  }
}

HTML

<form id="ate-final-submi" name="ate-final-submi"  method="post" action=""><br>
    <input type="text" id="ate-final-email" name="ate-final-email" value="asfd">
    <button type="button" id="ATE-backButton" class="ATE-nav-button">« Back</button>  
    <button type="submit" name="ATE-submitButton" id="ATE-submitButton" class="ATE-nav-button">
</form>

您可以尝试将其添加到HTML中：

<?php if (!empty($_POST['ATE-submitButton'])): ?>
   <script>
     alert('Form Submitted');
    </script>
<?php endif ?>
