1、内容页模板修改
调用之前将调用信息TAG的函数，放进 e/class/userfun.php 文件 ?> 代码之前，方便在模板中调用
/***
$classid 信息栏目id
$id 信息id
$exp 包裹每一个tag的前后标签，用|分割，默认是<li><a href=\"\">TAG</a></li>
$limit 调用tag数量，默认10个
***/
function dp_InfoTag($classid,$id,$exp=\"<li>|</li>\",$limit=10){
global $dbtbpre,$empire,$public_r;
$tagstr=\'\';
$i=0;
$q=explode(\"|\",$exp);
$tsql=$empire->query(\"select tagid from {$dbtbpre}enewstagsdata where id=\".$id.\" and classid=\".$classid.\"\");
while($tr=$empire->fetch($tsql)){
$tt=$empire->fetch1(\"select * from {$dbtbpre}enewstags where tagid=\".$tr[\'tagid\'].\" limit 1\");
if($tt[\'tagid\']){
if($i>$limit&&$limit){
break;
}
$tagurl=dp_itagLink($tr[\'tagid\']);
$tagstr.=$q[0].\'<a href=\"\'.$tagurl.\'\" title=\"\'.$tt[\'tagname\'].\'\" class=\"c1\" target=\"_blank\">\'.$tt[\'tagname\'].\'</a>\'.$q[1];
$i+=1;
}
}
return $tagstr;
}
1、在内容页模板中使用上述dp_InfoTag函数，调用当前信息的tag
<?=dp_InfoTag($navinfor[\'classid\'],$navinfor[\'id\'],\'|<br>\',8)?>2、列表页模板修改
$tagstr=dp_InfoTag($r[\'classid\'],$r[\'id\'],\'| \',5);
$listtemp=\'
<li>
<h3><a href=\"[!--titleurl--]\">[!--title--]</a></h3>
<p>[!--smalltext--]</p>
TAG:\'.$tagstr.\'
</li>
\';
注意需要勾选使用程序代码。3、首页模板修改
[e:loop={\"select * from {$dbtbpre}enewstags order by tagid limit 40\",0,24,0}]
<a href=\" <?=dp_itagLink($bqr[tagid])?>\" target=\"_blank\">
<?=$bqr[ \'tagname\']?>
</a>
[/e:loop]
4、调用最新10个TAG信息
<?
$tsql=$empire->query(\"select * from {$dbtbpre}enewstags order by num desc limit 10\");
while($tr=$empire->fetch($tsql)){
$tagurl=dp_itagLink($tr[\'tagid\']);
?>
<a href=\"<?=$tagurl?>\" target=\"_blank\" class=\"tag\"> <?=$tr[\'tagname\']?> <span class=\"count\"></span> </a>
<?
}
?>5、一级最新推荐
<?
$tsql=$empire->query(\"select * from {$dbtbpre}enewstags where isgood=1 order by tagid desc limit 24\");
while($tr=$empire->fetch($tsql)){
$tagurl=dp_itagLink($tr[\'tagid\']);
?>
<a href=\"<?=$tagurl?>\" target=\"_blank\"><?=$tr[\'tagname\']?></a>
<?
}
?>
六，栏目ID调用：
<?
$tsql=$empire->query(\"select * from {$dbtbpre}enewstags where cid=2 order by tagid desc limit 30\");
while($tr=$empire->fetch($tsql)){
$tagurl=dp_itagLink($tr[\'tagid\']);
?>
<a href=\"<?=$tagurl?>\" target=\"_blank\"><?=$tr[\'tagname\']?></a>
<?php
}
?>七，关键词自动替换，放进 e/class/userfun.php 文件 ?> 代码之前
function tihuan($id) {
global $empire, $dbtbpre, $public_r, $class_r;
// 获取新闻的基本信息和内容
$tagr = $empire->fetch1(\"select id, classid from {$dbtbpre}ecms_news where id=\'$id\' limit 1\");
$f = $empire->fetch1(\"select newstext from {$dbtbpre}ecms_news_data_1 where id=\'$id\' limit 1\");
$newstext = $f[\'newstext\'];
// 获取新闻的标签ID
$sql = $empire->query(\"select tagid from {$dbtbpre}enewstagsdata where id=\".$tagr[\'id\'].\" and classid=\".$tagr[\'classid\'].\"\");
// 用于存储已处理的标签ID，确保不重复替换
$processedTagIds = [];
while ($td = $empire->fetch($sql)) {
$tr = $empire->fetch1(\"select * from {$dbtbpre}enewstags where tagid=\".$td[\'tagid\'].\" limit 1\");
if ($tr[\'tagid\'] && !in_array($tr[\'tagid\'], $processedTagIds)) {
$processedTagIds[] = $tr[\'tagid\']; // 标记为已处理
$tagurl = dp_itagLink($td[\'tagid\']);
// 使用回调函数和正则表达式实现只替换一次
$newstext = preg_replace_callback(
\'/(\'.preg_quote($tr[\'tagname\'], \'/\').\')(?!([^<]*>)|([^<]*<\\/a>))/i\',
function ($matches) use ($tagurl) {
return \'<a href=\"\'.$tagurl.\'\" target=\"_blank\" class=\"infotextkey\">\'.$matches[1].\'</a>\';
},
$newstext,
1 // 这里的1表示只替换一次
);
}
}
return $newstext;
}
模板使用<?=tihuan($navinfor[\’id\’])?> 调用
