在网站SEO优化中url优化是相对来说比较重要的环节，wordpress分类的链接地址在wordpress程序中会自带category目录，例如：https://www.zhankr.net/category/learn。

如果能够去掉分类链接中的category无疑也是网站seo优化的一种手法。

下面分享一段去掉分类链接中的category的wordpress代码

使用方法

复制下面代码粘贴到functions.php文件里即可

//去掉分类链接中的category
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;
}

代码很长，也不用看懂，直接将上面代码添加到主题functions.php文件就行
