以前小站的固定链接好不人性化,结构是/%year%/%monthnum%/%postname%/,这样看起来又不直观又长的,今天做了一个301重定向,然后修改了新的固定链接,现在的固定链接格式是/%postname%.html,这样看起来短了好多,也直观了好多,不过小站已经被搜索引擎收录了好多,以前的地址都无法访问了,所以要做好301重定向,跳转到新的固定链接所生成的地址中去.要不然都是404就悲剧了.下面贴出解决办法
generate_rewrite_rule($rewrite_config['oldstructure'],false,true,true); if ($post != NULL && is_single() && $rewrite_config['oldstructure'] != $wp_rewrite->permalink_structure) { if (array_key_exists($wp->matched_rule,$rewrite_config['rewrite'])) { // ok,we need to generate a 301 Permanent redirect here. header("HTTP/1.1 301 Moved Permanently",TRUE,301); header('Status: 301 Moved Permanently'); $permalink = get_permalink($post[0]->ID); if (is_feed()) { $permalink = trailingslashit($permalink) . 'feed/'; } header("Location: ". $permalink); exit(); } } return $post;} function wpdaxue_pm_post_rewrite_rules($rules) { global $wp_rewrite; global $rewrite_config; $oldstruct = $rewrite_config['oldstructure']; if ($oldstruct != NULL && $oldstruct != $wp_rewrite->permalink_structure) { $rewrite_config['rewrite'] = $wp_rewrite->generate_rewrite_rule($oldstruct,true); if ($rewrite_config ['highpriority'] == true) { return array_merge($rewrite_config['rewrite'],$rules); } else { return array_merge($rules,$rewrite_config['rewrite']); } } return $rules;}add_filter('the_posts','wpdaxue_pm_the_posts',20);add_filter('post_rewrite_rules','wpdaxue_pm_post_rewrite_rules');
