WordPress优化之去掉分类链接中的category

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
