要提高这条语句在页面中的性能 博主将这个片段写入了自定义页面
这样就能在需要的页面 区域调用出来 而不需要时时访问数据库大约10分钟刷新一次 降低了 大数据下访客每次访问时都要查询多次数据库的巨大压力帝国7的包含自定义页面可以这么写<?php require(ECMS_PATH.’page1.html’);?>注意：page1.html在根目录。若在t目录则写成“t/page1.html”或[includefile]’../../page1.html'[/includefile] 注意：开启“[includefile]”标签 后台–模板–标签–标签管理–修改（选择对应标签）–开启———————————————————————-1、调用多模型的最新文章[e:loop={‘select * from (select id,classid,titleurl,filename,title,newstime,titlepic from [!db.pre!]ecms_movie where newstime unionselect id,classid,titleurl,filename,title,newstime,titlepic from [!db.pre!]ecms_news where newstime unionselect id,classid,titleurl,filename,title,newstime,titlepic from [!db.pre!]ecms_photo where newstime unionselect id,classid,titleurl,filename,title,newstime,titlepic from [!db.pre!]ecms_flash where newstime unionselect id,classid,titleurl,filename,title,newstime,titlepic from [!db.pre!]ecms_article where newstime) a order by newstime desc limit 10’,10,24,1}]<a href=”<?=$bqsr[‘titleurl’]?>” target=”_blank”><?=$bqr[‘title’]?></a> <br>[/e:loop]帝国CMS多表调用最新信息,该演示代码为默认数据表下全站最新10条图片信息,自己根据需求可以附加条件,实现全站点击,全站头条,全站推荐等等.注释：以上多个模型用“Union”连接调用若只调用图片：要加ispic=1条件举例：[e:loop={‘select * from (select id,classid,titleurl,filename,title,newstime,titlepic from [!db.pre!]ecms_news where newstime and ispic=1 unionselect id,classid,titleurl,filename,title,newstime,titlepic from [!db.pre!]ecms_photo where newstime and ispic=1 unionselect id,classid,titleurl,filename,title,newstime,titlepic from [!db.pre!]ecms_flash where newstime and ispic=1 unionselect id,classid,titleurl,filename,title,newstime,titlepic from [!db.pre!]ecms_article where newstime and ispic=1) a order by newstime desc limit 10’,10,24,1}]<a href=”<?=$bqsr[‘titleurl’]?>” target=”_blank”><img src=”<?=$bqr[‘titlepic’]?>”/><?=$bqr[‘title’]?></a> <br>[/e:loop]———————————————————————————2、调用多模型的最新文章[e:loop={‘select title,titleurl,titlepic from [!db.pre!]ecms_photo Union All select title,titleurl,titlepic from [!db.pre!]ecms_download Union Allselect title,titleurl,titlepic from [!db.pre!]ecms_news’,0,24,0}]<a href=”<?=$bqsr[‘titleurl’]?>” target=”_blank”><?=$bqr[‘title’]?></a> <br>[/e:loop]注释：以上调用的是（图片模型：photo、下载模型：download、新闻模型：news）三个模型的文章 三个模型用“Union All”连接调用若指定栏目用：where classid in(46,47,51)，若调用推荐在其后追加：and isgood=1，若指定调用条数在其后追加：limit 10举例：多表调用 同时显示“标题”所在的“栏目名称”和“链接” 及以“点击排行”[e:loop={“select titleurl,title,onclick,classid from phome_ecms_news union all select titleurl,title,onclick,classid from phome_ecms_article order by onclick desc limit 10″,1,24,0}]<LI><A href=”<?=$bqsr[classurl]?>” target=_blank><?=$bqsr[classname]?></A> | <A href=”<?=$bqsr[titleurl]?>” target=_blank><?=$bqr[title]?></A></LI>[/e:loop]———————————————————————————3、多表联合查询“主、副”表调用文章[e:loop={‘select * from ((select id,classid,title,titleurl,titlepic,newstime from [!db.pre!]ecms_download limit 3 )Union All(select id,classid,title,titleurl,titlepic,newstime from [!db.pre!]ecms_movie limit 3)) as A order by newstime desc ‘,0,24,0}]<?php$fb=$empire->fetch1(“select *from((select id,classid,downpath from {$dbtbpre}ecms_download_data_1 where id=’$bqr[id]’ and classid=’$bqr[classid]’)Union All(select id,classid,downpath from {$dbtbpre}ecms_movie_data_1 where id=’$bqr[id]’ and classid=’$bqr[classid]’)) as A”);$olurl=explode(‘::::::’,$fb[‘downpath’]);?><li><a href=”<?=$bqsr[‘titleurl’]?>”><img src=”<?=$bqr[‘titlepic’]?>”
