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]
9 <?php }
10 else if(strpos($title,'仓库') !== false){?>
11 [e:loop={"select * from [!db.pre!]enewszt where zcid='$zr[zcid]' and ztpagekey like '%管理%' or ztpagekey like '%仓库%' or ztpagekey like '%系统%' order by rand() limit 20",0,24,0}]<li><a href="/<?=$bqr[ztpath]?>/" target="_blank" title="<?=$bqr[ztname]?>"><u><?=$bqr[ztname]?></u></a></li>[/e:loop]
12 <?php }
13 else if(strpos($title,'器') !== false){?>
14 [e:loop={"select * from [!db.pre!]enewszt where zcid='$zr[zcid]' and ztpagekey like '%软%' or ztpagekey like '%器%' or ztpagekey like '%下载%' or ztpagekey like '%音乐%' order by rand() limit 20",0,24,0}]<li><a href="/<?=$bqr[ztpath]?>/" target="_blank" title="<?=$bqr[ztname]?>"><u><?=$bqr[ztname]?></u></a></li>[/e:loop]
15 <?php }
16 else if(strpos($title,'大全') !== false){?>
17 [e:loop={"select * from [!db.pre!]enewszt where zcid='$zr[zcid]' and ztpagekey like '%全%' or ztpagekey like '%器%' or ztpagekey like '%系统%' or ztpagekey like '%软件%' order by rand() limit 20",0,24,0}]<li><a href="/<?=$bqr[ztpath]?>/" target="_blank" title="<?=$bqr[ztname]?>"><u><?=$bqr[ztname]?></u></a></li>[/e:loop]
18 <?php }else{?>
19 [e:loop={"select * from [!db.pre!]enewszt where zcid='$zr[zcid]' 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]
20 <?php }?>
21 </ul>
说明：当点击下载器；第5行会将带“下载”字符串的数据调出；同时，因为带“器”，第14行会将带“软”、“器”、“下载”、“音乐”的数据调出......
THE END
