自定义函数添加方法：
1.函数内容代码：
<?php
function user_ztotal($classid){
global $empire,$class_r,$dbtbpre;
$beginYesterday = mktime(0, 0, 0, date("m"), date("d") -1, date("Y"));
$endYesterday = mktime(0,0,0,date("m") ,date("d"),date("Y"));
$query="select count(*) as total from {$dbtbpre}ecms_".$class_r[$classid][tbname]." WHERE classid=".$classid." and newstime BETWEEN ".$beginYesterday." AND ".$endYesterday;
$num=$empire->gettotal($query);
echo $num;
}
?>2.将函数内容复制到e/class/userfun.php文件里
3.登陆后台->“模板管理”->“管理标签”->“增加标签”：
