帝国cms不同栏目调用不同的随机文章模板

有时候我们想实现不同的栏目调用不同的文章，但是还想用一个模板，方法如下：
如果来源为空则输入本站整理，不为空输入来源作者
<?
if($navinfor['befrom']=="") {
echo "本站整理";
}
else{
echo $navinfor[befrom];
}
?>
如果作者为空，则不输出任何内容，那么添加样式以及作者
<?
if($navinfor['writer']=="") {
echo '';
}
else{
echo '<span>作者：'.$navinfor[writer].'</span>';
}
?>
<?php
if($GLOBALS[navclassid]=="129") {
 srand( microtime() * 1000000 );
 $num = rand( 1, 4 );
 switch( $num )
 {
 case 1: $image_file = "<a href='#' target='_blank'>1</a>";
     break;
 case 2: $image_file = "<a href='#' target='_blank'>2</a>";
     break;
 case 3: $image_file = "<a href='#' target='_blank'>3</a>";
     break;
 case 4: $image_file = "<a href='#' target='_blank'>4</a>";
     break;
 }
 echo "$image_file";
 }
 else{
echo $navinfor[befrom];
}
?>
如果栏目ID=129，则输出1-4随机一个a标签数字，如果不是输出文章来源
进阶版：
