自动添加标签及内链的功能代码;只需要把代码复制到主题函数functions.php文件当中,功能就可以实现了 主题的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);
- $url = "<a href="$link" title="".str_replace('%s',addcslashes($cleankeyword, '$'),__('【查看含有[%s]标签的文章】')).""";
- $url .= ' target="_blank"';
- $url .= ">".addcslashes($cleankeyword, '$')."</a>";
- $limit = rand($match_num_from,$match_num_to);
- $content = preg_replace( '|(<a[^>]+>)(.*)('.$ex_word.')(.*)(</a[^>]*>)|U'.$case, '$1$2%&&&&&%$4$5', $content);
- $content = preg_replace( '|(<img)(.*?)('.$ex_word.')(.*?)(>)|U'.$case, '$1$2%&&&&&%$4$5', $content);
- $cleankeyword = preg_quote($cleankeyword,'\'');
- $regEx = '\'(?!((<.*?)|(<a.*?)))('. $cleankeyword . ')(?!(([^<>]*?)>)|([^>]*?</a>))\'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 */
