PHPCMS loads different advertisements based on column placement

PHPCMS loads different advertisements according to column placement
First, create an advertisement configuration file and place it in caches/config/ad.php:

//Load ads

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]=<<


< script type="text/javascript" >BAIDU_CLB_SLOT_ID = "XXXXX";



EOF;


$ad['other']=<<
