WordPress去掉链接category方法

WordPress默认分类目录链接会带有category , 为了链接扁平化,层级不超过三级,更有利于Seo优化,所以要删掉category层级。

在主题文件functions.php中加上下面代码即可。

  
//删除链接category目录 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; }
