helper_makehtml 中为什么得不到 uid

Question

我想在helper_makehtml 中记录生成日志， uid 怎么是 0；请问如何获得。

class helper_makehtml {
	public static $callback;
	public static $callbackdata;
	public static $htmlfilename;
	public static $returndata = array();
	public static $viewurl;
	public static function make_html() {
		global $_G;
echo $_G['uid']; 这里等于0，得不到 uid

解决了

if($this->var['group']['allowmakehtml'] && isset($_GET['_makehtml'])) {
			$this->var['makehtml'] = 1;
			$this->_init_guest();

重置了，why ?
