Question

这是我在此页面上唯一的PHP，我正在尝试获取产品的详细信息，以显示更大的图像和有关该产品的其他详细信息。我没有得到任何PHP页面的错误，但没有显示该产品的内容。

    $database = new Database();
    $conn=$database->getConnection();
    $tree_product = new tree_product($conn);
    $tree_product->id=$_GET['detailsid'];
    $stmt=$tree_product->readDetails();
while($row=$stmt->fetch(PDO::FETCH_ASSOC)){

?>

<div id="main_tree">
 <img src="img/lg_tree/<?php echo $row['lgpic']; ?>" alt="" />
</div>

<div id="tree_detail">
 <span class="cat_name">Name: </span><span class="name"><?php echo $row['name']; ?></span><br>
 <span class="cat_name">Latin Name: </span><span class="latin"><?php echo $row['name']; ?></span><br>
 <span class="cat_name">Price: </span><span class="price">$<?php echo $row['name']; ?></span><br>
 <span class="cat_name">Description: </span><span class="description><?php echo $row['name']; ?></span><br>

 }

Answer 2
