我正在尝试从我的管理设置页面上发布一个新插件的请求。

提交后，以下代码将我带到一个空白页（URL为：http://192.168.1.33:3000/wptest2/wp-admin/admin-post.php).

没有var转储，没有重定向到google。没有控制台错误，我在日志中也没有看到任何apache错误。我怀疑表单没有提交到正确的目的地。

 <form
    action="<?php echo
      esc_url(admin_url(\'admin-post.php\'));
    ?>"
    method="post"
    id="newCouponForm"
    enctype="multipart/form-data"
  >
    <input
      type="hidden"
      name="action"
      value="handleNewCoupon"
    >
    <button type="submit">Create New Coupon</button>
  </form> 
// other form fields removed

// in my main plugin file
function setupCouponTargetImageUpload() {

  ?>
    <script>
      console.log(`=====test=====`); // doesn\'t log
    </script>
  <?php  

  $couponType = selectCouponType();
  var_dump($couponType);
  echo \'=====$couponType=====\'; // doesn\'t echo

  if($couponType === \'image\') {
    insertImageCoupon();
  } else if ($couponType === \'text\') {
    insertTextCoupon();
  }

  wp_redirect(\'http://google.com\'); // no redirect
  exit; // removing this has no effect either
}

add_action(\'admin_post_handleNewCoupon\', \'setupCouponTargetImageUpload\');

这是在Chrome的“网络”选项卡中向管理员发布的请求。有人能发现这个请求的问题吗？
