dedecms织梦tag keyword怎么调用相关文章？
dede官方的dede:likearticle是利用文章中输入的关键词或者自动分词形成的关键词来关联文章，但是有时候自动生成的关键词并不精确，造成关联不准，这里我们通过自定义一个类库文件来实现精准获取相关文章
推荐学习：织梦cms
可以单用tag来调用相关文章,也可用tag+keyword来调用相关文章(默认tag优先于keyword,可以自己排序)
在 \include\taglib\ 下添加一个liketags.lib.php 代码如下
<?phpif(!defined('dedeinc')) exit('request error!');function lib_liketags(&$ctag,&$refobj){ global $dsql; //属性处理 $attlist="row|12,titlelen|30,infolen|250,col|1,tablewidth|100,mytypeid|0,byabs|0,imgwidth|1,imgheight|90,flag|"; fillattsdefault($ctag->cattribute->items,$attlist); extract($ctag->cattribute->items, extr_skip); $revalue = ''; if(empty($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 { $keyword = ( !empty($refobj->fields['keywords']) ? $refobj->fields['keywords'] : '' ); } $typeid = ( !empty($mytypeid) ? $mytypeid : 0 ); if(empty($typeid)) { if(!empty($refobj->typelink->typeinfos['reid'])) { $typeid = $refobj->typelink->typeinfos['reid']; } else { if(!empty($refobj->fields['typeid'])) $typeid = $refobj->fields['typeid']; } } if( !empty($typeid) && !preg_match('#,#', $typeid) ) { $typeid = getsonids($typeid); } if(!empty($refobj->fields['tags']) && $eregtype != 'keyword' ){$tags = explode(',', addslashes($refobj->fields['tags']));$getsql = " tag like '".join("' or tag like '", $tags)."'
