当PHP被执行，除非其隐藏

使用我的PHP来显示结果到我的网页

<div class="alert alert-success" role="alert"> 
     <?php  
     if(isset($_POST['submit'])){ //check if form was submitted 
     include "assets/backend/newsletter.php"; 
     } 
     ?> 
</div>

即使不执行的PHP代码中，我可以看到空白面板。我该如何摆脱？

[图片供参考。] [1]我想在你们的情况下，这种方式使得更多的SENS那么什么是U在那里做：

<?php  
if(isset($_POST['submit'])){ ?> 
<div class="alert alert-success" role="alert"> 
<?php include "assets/backend/newsletter.php"; ?> 
</div> 
<?php}?>

如果提交表单的面板会出现这样如果未提交，面板将不可见。

footer.php 
<div class="container"> 
    <div class="row"> 
    <?php  
     if(isset($_POST['submit'])){ 
      echo '<div class="alert alert-success" role="alert"> '; 
      include 'assets/backend/newsletter.php'; 
      echo '</div>'; 
     } 
     ?> 
    </div>

或该：

<div class="container"> 
    <div class="row"> 
    <?php  
     if(isset($_POST['submit'])){ ?> 
     <div class="alert alert-success" role="alert"> 
      <?php 
      include 'assets/backend/newsletter.php'; 
      ?> 
      </div> 
     <?php 
     } 
     ?> 
    </div> 

<div class="container-fluid" style="background-color:#222222"> 
    <div class="row"> 
     <div class="container" style="margin-top:15px; 
      margin-bottom:15px"> 
      <div class="col-lg-4" style="color:#f3f6f9"> 
       <img src="images/pc%20logo.png" width="80px" height="80px">

@Bhanusingh份额footer.php –

我编辑我的答案和添加footer.php –
