修改phpcms/model/content_model.class.php大概454行的update_category_items()函数
PHP代码
- private function update_category_items($catid,$action = 'add',$cache = 0) {
- $this->category_db = pc_base::load_model('category_model');
- if($action=='add') {
- $this->category_db->update(array('items'=>'+=1'),array('catid'=>$catid));
- } else {
- $this->category_db->update(array('items'=>'-=1'),array('catid'=>$catid));
- }
- if($cache) $this->cache_items();
- }
