WordPress 在撰写日志的时候,可以给日志添加摘要(excerpt)和标签(tag),我的做法就是,就如给日志添加了摘要就把摘要做为 Description,如果没有设置摘要的话,则截取文章的前 220 个字作为 Description,而标签直接作为 Keywords。代码如下:
<?if (is_home()){ $description = "phpabc.cn"; $keywords = "php,seo,wordpresss"; } elseif (is_single()){ if ($post->post_excerpt) { $description = $post->post_excerpt; } else { $description = substr(strip_tags($post->post_content),0,220); } $keywords = ""; $tags = wp_get_post_tags($post->ID); foreach ($tags as $tag ) { $keywords = $keywords . $tag->name . ", "; } } ?> <meta name="keywords" content="<?=$keywords?>" /> <meta name="description" content="<?=$description?>" /> |
