WordPress去掉分类链接中category

24小时自助开通VIP,马上拥有站内全部资源

有很多朋友都不喜欢分类链接中的category,想改成累似本的链接形式,例如https://mk99.net/category/117.html改成https://mk99.net/117.html


这样看起来链接不仅美观,还有利于收录。


实现方法


找到主题跟木下的functions.php,有的主题可能是别的文件,例如本站使用的主题为customfunctions.php,在最后一行添加如下代码:


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 baseadd_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 { $wp_rewrite -> extra_permastructs['category']['struct'] = '%category%'; }}// Add our custom category rewrite rulesadd_filter('category_rewrite_rules', 'no_category_base_rewrite_rules');function no_category_base_rewrite_rules($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 $category_rewrite;}// Add 'category_redirect' query variableadd_filter('query_vars', 'no_category_base_query_vars');function no_category_base_query_vars($public_query_vars) { $public_query_vars[] = 'category_redirect'; return $public_query_vars;}// Redirect if 'category_redirect' is setadd_filter('request', 'no_category_base_request');function no_category_base_request($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;}

如果更新后显示404页面,请重新保存下固定链接。
