只需要将下列代码放入主题的functions.php文件中即可
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 | /* http://cwhello.com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); $url = "<a title="\"".str_replace('%s',addcslashes($cleankeyword," href="\"$link\"" target="_blank" rel="noopener">".addcslashes($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 .

把functions.php文件更新覆盖后,再看看我们的文章,在出现过我们添加的标签关键词的时候就会自动加上链接。
很强大,很棒棒,采用一下我会起飞么~
