PHP
//设置全局环境变量
$this->Fields['typename'] = $this->Typelink->TypeInfos['typename'];
@SetSysEnv($this->Fields['typeid'],$this->Fields['typename'],$this->Fields['id'],$this->Fields['title'],'archives');

PHP
//替换图片Alt为文档标题
$this->Fields['body'] = str_ireplace(array('alt=""','alt='''),'',$this->Fields['body']);
$this->Fields['body'] = preg_replace("@ [s]{0,}alt[s]{0,}=["'s]{0,}[sS]{0,}["'s]@isU"," ",$this->Fields['body']);
$this->Fields['body'] = str_ireplace("Fields['title'].""",$this->Fields['body']);
//屏蔽height属性
$this->Fields['body'] = preg_replace('//i',"",$this->Fields['body']);
$this->Fields['body'] = preg_replace('//i',"",$this->Fields['body']);
