phpcms根据栏目放置加载不同广告方法分享

代码如下:

//加载广告
function ad_block($catid){
$adblocks = pc_base::load_config('ad',$catid);
if(empty($adblocks)){
$model = pc_base::load_model("category_model");
$catid = $model->get_one(array('catid'=>$catid));
$adblocks = pc_base::load_config('ad',$catid['parentid']);

if(empty($adblocks) && $catid['parentid'] != 0){
$adblocks = ad_block($catid['parentid']);
}

if(empty($adblocks)||is_array($adblocks)){
$adblocks = pc_base::load_config('ad','other');
}
}
return $adblocks;
}

$ad = array();
$ad[1234]=<<<EOF
<!-- 广告位：1234-栏目独立广告位 -->;
<script type="text/javascript" >BAIDU_CLB_SLOT_ID = "XXXXX";</script>
<script type="text/javascript" src="<a href="http://cbjs.baidu.com/js/o.js"></script">http://cbjs.baidu.com/js/o.js"></script</a>>
EOF;
$ad['other']=<<<EOF
<!-- 广告位：0000-默认显示广告位 -->
<script type="text/javascript" >BAIDU_CLB_SLOT_ID = "XXXXX";</script>
<script type="text/javascript" src="<a href="http://cbjs.baidu.com/js/o.js"></script">http://cbjs.baidu.com/js/o.js"></script</a>>
