Question

我有一个购物网站。因为当我们点击某个特定产品时，它将获取该产品的ID，并将使用该ID加载另一个页面。但是当我打开网站并点击任何页面未显示的产品时。它继续加载。当我重新加载它工作正常。它只在第一次发生。之后，当我点击产品时，页面会显示。请帮我。提前谢谢

我已附上网页代码

     $id = $_GET['id'];
   $_SESSION['abaya']= $id;

以上代码是我获取ID的地方。我附上了下面的特定页面

<!DOCTYPE html>
<html lang="en"><head>
<meta charset="utf-8">
<title>Abayat Dubai</title>
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">
