织梦DEDE文章tag标签或者文章keyword重要字调用有关文章

企业模板

官方的dede:likearticle并没有那样精准的输出有关文章,下面大家自概念一个类库文件来达成精准获取有关文章,支持直接输出自概念字段,支持flag文章属性,非常适合SEO

eregtype='all|tag|keyword',单用tag来调用有关文章,也可用tag|keyword来调用有关文章(默认tag优先于keyword,可以我们排序)

在 /include/taglib 下添加一个 liketags.lib.php 文件代码如下

<?php

if(!defined('DEDEINC')) exit('Request Error!');

function lib_liketags(&$ctag,&$refObj)

{

global $dsql,$envs;

//属性处理

$attlist="row|12,titlelen|30,infolen|250,col|1,tablewidth|100,typeid|0,byabs|0,imgwidth|120,imgheight|90,flag|";

$revalue = '';

if(empty($tablewidth)) $tablewidth = 100;

if(empty($col)) $col = 1;

$colWidth = ceil(100/$col);

$tablewidth = $tablewidth."%";

$colWidth = $colWidth."%";

$orwheres = '';

if($flag != '') {

$flags = explode(',', $flag);

for($i=0; isset($flags[$i]); $i++) $orwheres .= " AND FIND_IN_SET('{$flags[$i]}', arc.flag)>0 ";

}

$ids = array();

$tids = array();

if(!empty($refObj->Fields['tags'])) {

$keyword = $refObj->Fields['tags'];

else {

$typeid = ( !empty($typeid) ? $typeid : 0 );

前台模板标签调用写法

{dede:liketags row='3' typeid='6' titlelen='250' eregtype='all|tag|keyword' flag='c' infolen='250'}

<li>

<a href="[field:arcurl/]" title="[field:title/]" target="_blank">

<p class="list-img">

<img src="[field:litpic/]" alt="[field:title/]"/>

</p>

<p class="list-info">

<p class="title">[field:title/]</p>

<p class="meta">¥[field:jiage/]元</p>

</p>

</a>

</li>
