【问题描述】：
我正在尝试为每种产品显示以下框之一：(Image here)。但是当我在数据库中添加另一个产品时，它似乎没有为我的产品页面添加另一个视图。 Here 你看到了我的数据库，但我的产品页面上只有一张图片。该页面看起来与上面发布的第一张图片相同。如果有人知道为什么我的产品没有显示每个产品，只有第一个产品，请告诉我。 我知道我的代码不安全，不整洁。在我完成这项工作后我会这样做，所以不要以此评判我。只有我问的问题。谢谢。
我的 PHP 代码都在我在 div 容器中调用的这个函数中：
function grabProducts($con) {
?>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="col-md-12" id="please_wait">
<div class="panel panel-warning">
<div class="panel-heading">
<h3 class="panel-title"><i>Loading, Please Wait...</i></h3>
</div>
<div class="panel-body">
</div>
</div>
</div>
<script>
$(document).ready(function() {
$('#please_wait').fadeOut(7000);
$('#content_purchase').hide(0).delay(5000).fadeIn("slow");
});
</script>

【问题讨论】：
-
您忘记了起始标签或此处出现语法错误 ';休息; case "show_success": ?> 可能这就是它没有显示超过 1 个产品的原因。
-
@MahmoodSanjrani 哦，是的，谢谢，但这还没有解决。
-
必须尝试在 while 循环中打印一些内容。可能是循环没有按预期工作。
