wordpress的默认固定链接样式导致分类页的地址中间多一个category,比如我的https://www.xpdlz.com/article,默认的会显示为https://www.xpdlz.com/category/article,这样会影响百度收录,SEO优化,并且链接长了,看的也不够简洁。今天在网上查找了很多办法,有伪静态设置的问题,也有在固定链接写一个半角.的方法,但是由于我的服务器使用的是kangle,导致要么不生效,要么分类页404。经过长时间的探索,终于研究出一种既不需要安装插件拖慢运行速度,又不需要调试服务器伪静态的方法。直接上代码:
/* *WordPress去除category*/add_action( 'load-themes.php', 'no_category_base_refresh_rules'); add_action('created_category', 'no_category_base_refresh_rules'); add_action('edited_category', 'no_category_base_refresh_rules'); add_action('delete_category', 'no_category_base_refresh_rules'); function no_category_base_refresh_rules() { global $wp_rewrite; $wp_rewrite -> flush_rules(); } // register_deactivation_hook(__FILE__, 'no_category_base_deactivate'); // function no_category_base_deactivate() { // remove_filter('category_rewrite_rules', 'no_category_base_rewrite_rules'); // // We don't want to insert our custom rules again // no_category_base_refresh_rules(); // } // Remove category base add_action('init', 'no_category_base_permastruct'); function no_category_base_permastruct() { global $wp_rewrite, $wp_version; if (version_compare($wp_version, '3.4', '<')) { // For pre-3.4 support $wp_rewrite -> extra_permastructs['category'][0] = '%category%'; } else { $wp_rewrite -> extra_permastructs['category']['struct'] = '%category%'; } } // Add our custom category rewrite rules add_filter('category_rewrite_rules', 'no_category_base_rewrite_rules'); function no_category_base_rewrite_rules($category_rewrite) { //var_dump($category_rewrite); // For Debugging $category_rewrite = array(); $categories = get_categories(array('hide_empty' => false)); foreach ($categories as $category) { $category_nicename = $category -> slug; if ($category -> parent == $category -> cat_ID)// recursive recursion $category -> parent = 0; elseif ($category -> parent != 0) $category_nicename = get_category_parents($category -> parent, false, '/', true) . $category_nicename; $category_rewrite['(' . $category_nicename . ')/(?:feed/)?(feed|rdf|rss|rss2|atom)/?$'] = 'index.php?category_name=$matches[1]&feed=$matches[2]'; $category_rewrite['(' . $category_nicename . ')/page/?([0-9]{1,})/?$'] = 'index.php?category_name=$matches[1]&paged=$matches[2]'; $category_rewrite['(' . $category_nicename . ')/?$'] = 'index.php?category_name=$matches[1]'; } // Redirect support from Old Category Base global $wp_rewrite; $old_category_base = get_option('category_base') ? get_option('category_base') : 'category'; $old_category_base = trim($old_category_base, '/'); $category_rewrite[$old_category_base . '/(.*)$'] = 'index.php?category_redirect=$matches[1]'; //var_dump($category_rewrite); // For Debugging return $category_rewrite; } // Add 'category_redirect' query variable add_filter('query_vars', 'no_category_base_query_vars'); function no_category_base_query_vars($public_query_vars) { $public_query_vars[] = 'category_redirect'; return $public_query_vars; } // Redirect if 'category_redirect' is set add_filter('request', 'no_category_base_request'); function no_category_base_request($query_vars) { //print_r($query_vars); // For Debugging if (isset($query_vars['category_redirect'])) { $catlink = trailingslashit(get_option('home')) . user_trailingslashit($query_vars['category_redirect'], 'category'); status_header(301); header("Location: $catlink"); exit(); } return $query_vars; }
方法
直接在当前主题的模板函数functions.php最后加入这串代码并保存,然后保存wordpress默认的固定链接两次,你会发现已经成功去除了烦人的category,同时访问带有category的链接也是可以访问的。
