如何免插件实现WordPress网站去掉分类链接中category目录？折腾WordPress的朋友都知道在分类链接中会出现一个/category/目录，网上也出现了各种去除category目录的类似插件，比如WP No category Base 插件。但安装过多插件对wordpress网站加载很不友好。可以通过不用插件来实现WordPress去掉分类链接中category目录，将下面代码添加到你当前用的wordpess主题的functions.php 文件中保存即可：
//WordPress免插件去除分类category
if (git_get_option('git_category_b')) {
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', '<')) {
} 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;
}
保存后，你打开目录链接时有可能显示404等打不开情况。请在登录后台-设置-固定链接设置，点击一下那个“保存更改”，即可。
默认wordpress链接伪静态后首页分页是：你的域名/page/页数，内页是：域名/category/分类别名/page/页数。链接目录太深对搜索引擎蜘蛛抓取不太好，还越短越好。
以上就是WordPress纯代码去掉分类目录前缀URL链接中自带category的方法。
