我正在为学校做一个项目。截止日期是明天。 当网址为：时，我想更改正文标记并在产品页面上添加背景图片： index.php？category = nieuwBinnen＆amp; product = Belair + X ch
我怎样才能做到这一点。我尝试了if isset方法但结果没有成功。 您可以在http://alisgfx.com/lomo/上看到该网站 我感谢任何帮助。

您可以使用JavaScript / JQuery动态设置它。
答案 1 :(得分：0)
可以尝试类似：
$targetpage = $_SERVER['SERVER_NAME'].'/index.php?category=nieuwBinnen&product=Belair+X'
if (!$targetpage) {
echo background 1;
}else{
echo background 2;
}
答案 2 :(得分：0)
$ class='no-bgimage'; if (isset($_GET['product']) {
$class='bgimage';
}
然后在你的身体
<body class="<?php echo $class ?>">
然后在你css
.bgimage {
background-image: url('page/to/your/image');
}
