WordPress自动为文章标签添加该标签的链接

wordpress 2019-03-15

站长朋友们在使用的过程中，当网站中的文章（post）和标签（tag）越来越多时，很多时候就希望给文章中出现的标签（tag）自动添加上该标签的链接。这篇WordPress教程里，我们就向大家介绍一下具体的方法。

切换到主题目录，打开functions.php文件，加入以下代码：

name == $b->name ) return 0; return ( strlen($a->name) > strlen($b->name) ) ? -1 : 1; } //为符合条件的标签添加链接 function tag_link($content){ global $match_num_from,$match_num_to; $posttags = get_the_tags(); //$posttags = get_tags(); if ($posttags) { usort($posttags,"tag_sort"); foreach($posttags as $tag) { $link = get_tag_link($tag->term_id); $keyword = $tag->name; //链接的代码 $cleankeyword = stripslashes($keyword); $url = ""; $limit = rand($match_num_from,$match_num_to); //不链接的代码 $content = preg_replace( '|(]+>)(.*)('.$ex_word.')(.*)(]*>)|U'.$case,'$1$2%&&&&&%$4$5',$content); $content = preg_replace( '|()|U'.$case,$content); $cleankeyword = preg_quote($cleankeyword,'\''); $regEx = '\'(?!((<.*?)|(]*?)>)|([^>]*?))\'s' . $case; $content = preg_replace($regEx,$url,$content,$limit); $content = str_replace( '%&&&&&%',stripslashes($ex_word),$content); } } return $content; }
