帝国CMS模板中的多条件筛选方法

需求：点击某一条目，调出与该条目关键词相关的类似词条数据

要点：

1.帝国CMS灵动标签使用 [e:loop=

2.专题关键词筛选 enewszt

3.SQL语句筛选 select * from [!db.pre!]enewszt where zcid='$zr[zcid]' and ztpagekey like '%下载%

4.随机排序 order by rand()

5.PHP 判断字符串存在 strpos($title,'下载') !== false

 1   <ul>
 2 <?php
 3 if(strpos($title,'下载') !== false)
 4 {?>
 5  [e:loop={"select * from [!db.pre!]enewszt where zcid='$zr[zcid]' and ztpagekey like '%下载%' order by rand() limit 20",0,24,0}]<li><a href="/<?=$bqr[ztpath]?>/" target="_blank" title="<?=$bqr[ztname]?>"><u><?=$bqr[ztname]?></u></a></li>[/e:loop]
 6 <?php 
 7 }else if(strpos($title,'软件') !== false){?>
 8 [e:loop={"select * from [!db.pre!]enewszt where zcid='$zr[zcid]' and ztpagekey like '%件%' or ztpagekey like '%器%' order by rand() limit 20",0,24,0}]<li><a href="/<?=$bqr[ztpath]?>/" target="_blank" title="<?=$bqr[ztname]?>"><u><?=$bqr[ztname]?></u></a></li>[/e:loop]
