比如我写好的POST提交例子,验证邮箱和值是否未空?

<code>include("check.php");

  $check = new VerifyAction();

  if(?){
   echo '提交成功!';
  }else{
    echo '填写不对 重填写';
 }



<form action="index.php" method="post">
   <input type="text" name="name"><br>
   <input type="text" name="email"><br>
   <input type="submit">
   </form>
