织梦文章tag标签或者文章keyword关键字调用相关文章

  官方的dede:likearticle并没有那么精准的输出相关文章,下面我们自定义一个类库文件来实现精准获取相关文章,支持直接输出自定义字段,支持flag文章属性,非常适合SEO

  eregtype=’all|tag|keyword’,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 文件代码如下

  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’] : ” );

  }

  $typeid = ( !empty($typeid) ? $typeid : 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) ) {

  }
