wordpress文章的tag标签作用想必大家都是了解的，今天测速网给大家介绍的自动为文章添加以前使用过的tag标签，而且自动为文章的tag标签添加链接；只需要两段代码就可以轻松实现这个才seo优化十分有益处的功能。

WordPress纯代码实现自动添加文章标签的实现方法：只需要将以下代码添加到主题的functions.php文件最后一个?>即可。

area data-settings="dblclick" readonly >add_action('save_post', 'auto_add_tags');function auto_add_tags(){$tags = get_tags( array('hide_empty' => false) );$post_id = get_the_ID();$post_content = get_post($post_id)->post_content;if ($tags) {foreach ( $tags as $tag ) {// 如果文章内容出现了已使用过的标签，自动添加这些标签if ( strpos($post_content, $tag->name) !== false)wp_set_post_tags( $post_id, $tag->name, true );}}}area>1234567891011121314add_action('save_post', 'auto_add_tags');function auto_add_tags(){$tags = get_tags( array('hide_empty' => false) );$post_id = get_the_ID();$post_content = get_post($post_id)->post_content;if ($tags) {foreach ( $tags as $tag ) {// 如果文章内容出现了已使用过的标签，自动添加这些标签if ( strpos($post_content, $tag->name) !== false)wp_set_post_tags( $post_id, $tag->name, true );}}}

WordPress纯代码实现自动为文章内的标签添加内链的方法：同样是将以下代码添加到主题的functions.php文件最后一个?>即可。

area data-settings="dblclick" readonly >$match_num_from = 1;//一篇文章中同一个标签少于几次不自动链接$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 $content;}add_filter('the_content','tag_link',1);area>16171819202122232425262728293031$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);

当然添加好完成后要起到效果必须保证您的程序内，有足够多的标签可以被提取出来。标签当然也是要手动添加的，而且在添加标签时记得一起加上标签描述这点对标签来讲是至关重要的。测速网的开发的所有主题都已经添加了此功能。
