之前小编更新了一篇教程 《WordPress 链接结构优化之标签 (tag) 存档页优化》,该教程是说明如何去除 tag 页面的链接中的/tag/这一段,现在又有小伙伴问小编如何去除分类存档页中的/category/,正好今天没事,就把方法更新出来,其实之前小编介绍的一个插件也可以达到这个效果:WP No Category Base,不过有些人是喜欢代码来解决,其实也很简单,只要插件的代码加到 functions.php 中,代码如下:
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; }
加好代码后到后台再次固定链接即可。现在标签 (Category) 页面的链接就变成了以下这种结构:http://域名/Category-name/,而 tag 页的分页链接结构为:http://域名/Category-name/page/page-id/,也就是说成功的去除了链接中的 category 。
