WordPress无插件去除分类"Category"标签方法

老蒋在"No Category Base快速去除"category"标签"文章中有提到利用no-category-base-wpml插件可以去除分类"Category"中固定的字符效果，但是本着尽量少用插件的原则。这里整理到一个无插件实现去除Category标签的方法，如果我们有需要的话可以使用。

第一、脚本代码

> //去除分类Category标签
> 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();
> }
> // 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;
> }

第二、使用方法

将上面脚本放到当前主题Functions.php文件中。然后我们看看是否有效，有些主题可能会出现冲突导致页面问题，我们可以去掉而采用插件方法。
