我正在撰写一个网站，用户可以在其中查看彼此的个人资料和待售产品。我的配置文件部分已完成，并且一直有效，直到我尝试集成产品部分。它似乎破坏了整个网站。
我想要实现的目标是从数据库中获取产品并将其显示在网格中，其中包含上传产品用户名和产品说明的用户。最终，我将在产品图片下对产品进行5星评价，但这不是在这里，也不在那里。
我使用与用户网格和数据库相同的代码，但它没有按预期工作。
我的产品页码是：
<?php
include 'controllers/grid/products-grid.php';
?>
产品网格页面是：
<?php include 'components/authentication.php' ?>
<?php include 'controllers/base/head.php' ?>
<?php include 'controllers/navigation/first-navigation.php' ?>
<div class="container">
<div class="row clearfix">
<div class="col-md-12 column">
<div class="row clearfix">
<?php
include '_database/database.php';
session_start();
$current_user = $_SESSION['user_username'];
$sql = "SELECT * FROM user WHERE product_id != '$product_id' order by product_id desc";
$result = mysqli_query($database,$sql) or die(mysqli_error($database));
while($rws = mysqli_fetch_array($result)){
?>
<div class="col-md-4 column">
<div class="panel-group" id="panel-<?php echo $rws['product_id']; ?>">
<div class="panel panel-default">
<div id="panel-element-<?php echo $rws['user_id']; ?>" class="panel-collapse collapse in">
<div class="panel-body">
<div class="col-md-6 column">
<img src="products/<?php echo $rws['user_avatar'];?>" name="products" class="img-responsive"> </div>
<div class="col-md-6 column">
<h2><span><a href="product.php?product_id=<?php echo $rws['product_name'];?>"><? php echo $rws['user_username'];?> <?php echo $rws['product_description'];?></a> </span></h2>
</div>
</div>
</div>
</div>
</div>
</div>
<?php } ?>
</div>
</div>
</div>
</div>
我的产品sql页面是：
