  • 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
