# **WordPress 纯代码去掉 URL 的 Category 分类前缀**

2017.07.15 3,494  0

折腾 WordPress 的小伙伴们都知道，一些没有集成去除 `/category/` 功能的主题，在每次修改固定链接后，分类链接中会出现一个 `/category/` 目录。如果想要去掉分类链接中的 `/category/` 目录，可以使用插件。网上也有许多插件可以直接去除（其实很多主题已经内置了这个功能）。但是，今天带来的是纯代码版去掉 `/category/`，适合那些不喜欢用插件的小伙伴喔。

## PHP 代码

 PHP

```
// 去除分类 category 的代码
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();
}
add_action('init', 'no_category_base_permastruct');
function no_category_base_permastruct() {
    global $wp_rewrite, $wp_version;
    if (version_compare($wp_version, '3.4', '<')) {
        $wp_rewrite->extra_permastructs['category'][0] = '%category%';
    } else {
        $wp_rewrite->extra_permastructs['category']['struct'] = '%category%';
    }
}
add_filter('category_rewrite_rules', 'no_category_base_rewrite_rules');
function no_category_base_rewrite_rules($category_rewrite) {
    $category_rewrite = array();
    $categories = get_categories(array('hide_empty' => false));
    foreach ($categories as $category) {
        $category_nicename = $category->slug;
        if ($category->parent == $category->cat_ID)
            $category->parent = 0;
        elseif ($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]';
    }
    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]';
    return $category_rewrite;
}
add_filter('query_vars', 'no_category_base_query_vars');
function no_category_base_query_vars($public_query_vars) {
    $public_query_vars[] = 'category_redirect';
    return $public_query_vars;
}
add_filter('request', 'no_category_base_request');
function no_category_base_request($query_vars) {
    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;
}
```

将以上代码添加到你当前主题的 `functions.php` 文件中，紧接在最后一个 `?>` 前即可。

无论是安装插件还是使用代码，都可能会出现 404 页面错误，即 `%post_id%.html`（本站设置的固定链接）的伪静态失效了。这种情况下，只需重新保存一次固定链接设置即可。
