在wordpress後臺編輯header.php檔案，在<head>標籤裡面，一般放在<title>標籤的下面比較美觀，加入如下程式碼。
<pre name="code" class="html"><?php $keywords = get_bloginfo('name'); $description = get_bloginfo('description', 'display'); if (is_home()){ $keywords = get_bloginfo('name'); $description = get_bloginfo('description', 'display'); } elseif (is_single()){ $keywords = get_post_meta($post->ID, "keywords", true); if($keywords == ""){ $tags = wp_get_post_tags($post->ID); foreach ($tags as $tag){ $keywords = $keywords.$tag->name.","; } $keywords = rtrim($keywords, ', '); } $description = get_post_meta($post->ID, "description", true); if($description == ""){ if($post->post_excerpt){ $description = $post->post_excerpt; }else{ $description = mb_strimwidth(strip_tags(apply_filters('the_content',$post->post_content)),0,200); } } } elseif (is_page()){ $keywords = get_post_meta($post->ID, "keywords", true); if($keywords == ""){ $keywords = get_bloginfo('title'); } $description = get_post_meta($post->ID, "description", true); if($description == ""){ if($post->post_excerpt){ $description = $post->post_excerpt; }else{ $description = mb_strimwidth(strip_tags(apply_filters('the_content',$post->post_content)),0,200); } } } elseif (is_category()){ $keywords = single_cat_title('', false); $description = category_description(); } elseif (is_tag()){ $keywords = single_tag_title('', false); $description = tag_description(); } $keywords = trim(strip_tags($keywords)); $description = trim(strip_tags($description)); ?> <meta name="keywords" content="<?php echo $keywords; ?>" /> <meta name="description" content="<?php echo $description; ?>" />
