我们在做织梦特码单双王开发时,为了更好的利于seo,在每篇文章下调用与这篇文章有着相同tag或keyword的相关文章。为了实现这个功能,自定义了一个标签:dede:liketags。标签代码如下:

自定义标签代码

1、新建一个文件名称为?liketags.lib.php,存放在/include/taglib/目录下。 该文件代码如下:

CAttribute->Items,$attlist);
    extract($ctag->CAttribute->Items, EXTR_SKIP);
    $revalue = '';
    
    if(empty($tablewidth)) $tablewidth = 100;

    $colWidth = ceil(100/$col);
    $tablewidth = $tablewidth."%";
    $colWidth = $colWidth."%";
	$orwheres = '';
	if($flag != '') {

2、前台特码单双王调用代码如下:

{dede:liketags row='3' mytypeid='6' eregtype='all|tag|keyword' titlelen='250' infolen='250'}
  • [field:title/]

    [field:title/]

    [field:description /]

  • {/dede:liketags}
