WordPress 纯代码实现页面锚文本链接
WordPress 实现页面锚文本链接的方法很多,由于装插件比较繁琐,所以这里老文笔记介绍一个WordPress 纯代码实现页面锚文本链接方法,在网站主题目录找到该文件 functions.php,具体路径:网站根目录:wp-content/themes/主题目录/ functions.php
//自动TAG转内链 https://www.wenrr.com/ 来源 $match_num_from = 1; // 一个TAG标签出现几次才加链接 $match_num_to = 1; // 同一个标签加几次链接 add_filter('the_content','tag_link',1); function tag_sort($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($cleankeyword, '$'),__('%s'))."\""; $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; }
在functions.php文件内,加入上面的代码,即可实现WordPress 纯代码实现页面锚文本链接。
