2. Smart tags And SQl statement call

Recommended to study "Empire cms tutorial"

The code is as follows:

[ e:loop={"select id,classid,newspath,filename,groupid,titleurl from [!db.pre!]ecms_".$class_r[$navinfor[classid]]['tbname']." where id<". $navinfor[id]." and classid=".$navinfor[classid]." and checked=1 order by id desc limit 1",1,24,0}]
$titleurl =sys_ReturnBqTitleLink($bqr);
echo $titleurl;
[/e:loop]

Next article link: (Change the less than sign to greater than sign)

The code is as follows:

[e:loop={"select id,classid,newspath,filename,groupid,titleurl from [!db.pre!]ecms_".$class_r[$navinfor[ classid]]['tbname']." where id>".$navinfor[id]." and classid=".$navinfor[classid]." and checked=1 order by id desc limit 1",1,24, 0}]
$titleurl=sys_ReturnBqTitleLink($bqr);
echo $titleurl;
[/e:loop]

3. Use smart tag call , a relatively concise way (thanks to Luo Mu Xiaoxiao)

The code is as follows:

[e:loop={'selfinfo', 1,0,0,'id<'.$navinfor[id].'','id desc'}]
Previous article:

[/e:loop ]
if(emptyempty($pre)){
echo "Previous post: Sorry, no more";
}
?>
< !--Next article-->
[e:loop={'selfinfo',1,0,0,'id>'.$navinfor[id].'','id asc'}]
Next article:

[/e:loop]
if(emptyempty($next)){
echo "Next Chapter: I'm sorry there are no more";
}
?>

4. Control the number of words in the title of the previous article and the next article (take 30 characters as an example)

Use :

The code is as follows:

The code is as follows:

<!--上一篇-->
[e:loop={&#39;selfinfo&#39;,1,0,0,&#39;id<&#39;.$navinfor[id].&#39;&#39;,&#39;id desc&#39;}]
<a href="<?php
echo $bqsr[titleurl];
$pre=&#39;true&#39;;
?>">上一篇: <?=esub($bqr[title],30)?></a>
[/e:loop]
<?php
if(emptyempty($pre)){
echo "上一篇:很抱歉没有了";
}
?>
<!--下一篇-->
[e:loop={&#39;selfinfo&#39;,1,0,0,&#39;id>&#39;.$navinfor[id].&#39;&#39;,&#39;id asc&#39;}]
<a href="<?php
echo $bqsr[titleurl];
$next=&#39;true&#39;;
?>">下一篇:<?=esub($bqr[title],30)?>
</a>
[/e:loop]
<?php
if(emptyempty($next)){
echo "下一篇:很抱歉没有了";
}
?>
