下面整理了完整的无插件实现标题以及关键字和描述的代码。只需要把下面的代码命名为title.php文件,放到主题模板中。
<?phpif( is_home() ) { ?><title><?php bloginfo('name'); ?> | <?php bloginfo('description'); ?></title><?php } ?><?phpif( is_search() ) { ?><title>搜索结果 | <?php bloginfo('name'); ?></title><?php } ?><?phpif( is_single() ) { ?><title><?php echo trim(wp_title('',0)); ?> | <?php bloginfo('name'); ?></title><?php } ?><?phpif( is_page() ) { ?><title><?php echo trim(wp_title('',0)); ?> | <?php bloginfo('name'); ?></title><?php } ?><?phpif( is_category() ) { ?><title><?php single_cat_title(); ?> | <?php bloginfo('name'); ?></title><?php } ?><?phpif( is_month() ) { ?><title><?php the_time('F'); ?> | <?php bloginfo('name'); ?></title><?php } ?><?phpif(function_exists('is_tag')) {if( is_tag() ) { ?><title><?php single_tag_title("",true); ?> | <?php bloginfo('name'); ?></title><?php } ?> <?php } ?><?phpif( is_author() ) {?><title><?php wp_title('');?>发表的所有文章 | <?php bloginfo('name'); ?></title><?php }?><?phpif(!function_exists('utf8Substr')) {functionutf8Substr($str, $from, $len){returnpreg_replace('#^(?:[\x00-\x7F]|[\xC0-\xFF][\x80-\xBF]+){0,'.$from.'}'.'((?:[\x00-\x7F]|[\xC0-\xFF][\x80-\xBF]+){0,'.$len.'}).*#s','$1',$str);}}if( is_single() ){if($post->post_excerpt) {$description = $post->post_excerpt;}else{if(preg_match('/<p>(.*)<\/p>/iU',trim(strip_tags($post->post_content,"<p>")),$result)){$post_content = $result['1'];}else{$post_content_r = explode("\n",trim(strip_tags($post->post_content)));$post_content = $post_content_r['0'];}$description = utf8Substr($post_content,0,220);}$keywords ="";$tags = wp_get_post_tags($post->ID);foreach ($tags as $tag ) {$keywords = $keywords . $tag->name .",";}}?><?php echo"\n"; ?><?phpif( is_single() ) { ?><meta name="description"content="<?php echo trim($description); ?>"/><meta name="keywords"content="<?php echo rtrim($keywords,','); ?>"/><?php } ?><?phpif( is_home() ) { ?><meta name="description"content="首页描述"/><meta name="keywords"content="首页关键字"/><?php } ?>
然后在header.php文件头部标题位置调用就可以:
<?php include('title.php'); ?>
