细心的朋友应该发现了,在WordPres分类目录的url中,有一层category的目录,这也是一个WordPres优化细节,如下图所示:

虽然这是WordPress程序中自带category目录,但是如果能够去掉这一层,那么也是对网站seo优化有利。

下面分享一段去除WordPres分分类链接中的category代码:

//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;
}

代码特别长,我估计很多人都看不懂,其实我也看不懂,不过其实也不用看懂,直接将上面代码添加到主题functions.php文件就行。
