WordPress文章自动添加标签链接变为内链

wordPress/ target=_blank class=infotextkey>WordPress有一个缺点,它不能自动智能地添加标签 。那么下面介绍的功能是自动添加标签和内部链的功能代码 。只需要将代码复制到主题functions.php文件中,这个功能就可以实现了 。
主题functions.php文件添加如下代码:
/* 自动为文章内的标签添加内链开始 */$match_num_from = 1; //一篇文章中同一个标签少于几次不自动链接$match_num_to = 1; //一篇文章中同一个标签最多自动链接几次function tag_sort($a, $b){ if ( $a->name == $b->name ) return 0; return ( strlen($a->name) > strlen($b->name) ) ? -1 : 1;}function tag_link($content){ global $match_num_from,$match_num_to; $posttags = get_the_tags(); if ($posttags) { usort($posttags, "tag_sort"); foreach($posttags as $tag) { $link = get_tag_link($tag->term_id); $keyword = $tag->name; $cleankeyword = stripslashes($keyword); $url = "<a href=https://www.isolves.com/it/cxkf/ky/WordPress/2019-12-02/"$link" title="".str_replace('%s',addcslashes($cleankeyword, '$'),__('【查看含有[%s]标签的文章】'))."""; $url .= ' target="_blank"'; $url .= ">".addcslashes($cleankeyword, '$').""; $limit = rand($match_num_from,$match_num_to); $content = preg_replace( '|(]+>)(.*)('.$ex_word.')(.*)(]*>)|U'.$case, '$1$2%&&&&&%$4$5', $content); $content = preg_replace( '|()|U'.$case, '$1$2%&&&&&%$4$5', $content); $cleankeyword = preg_quote($cleankeyword,'''); $regEx = ''(?!((<.*?)|(]*?)>)|([^>]*?))'s' . $case; $content = preg_replace($regEx,$url,$content,$limit); $content = str_replace( '%&&&&&%', stripslashes($ex_word), $content); } } return $content;}add_filter('the_content','tag_link',1);/* 自动为文章内的标签添加内链结束 */
