WooCommerce 只保留产品模块的处理办法

WooCommerce是一款非常棒的电子商城插件，但是有时候客户仅仅需要产品展示，并不需要这个插件的其他功能，比如支付 优惠券等等，所以很有必要精简掉这些功能，只保留产品模块。

这样不仅仅可以提高处理速度，也可以让后台响应变得更快。

(仅仅适配漫步白月光子主题)现在附上处理代码

/**
 * WooCommerce 精简配置
 */

// 1. 基础禁用
add_filter( 'woocommerce_coupons_enabled', '__return_false' );
add_filter( 'woocommerce_enable_setup_wizard', '__return_false' );

// 2. 确保管理员有所有必要的权限
add_action( 'init', 'at8_fix_admin_capabilities' );
function at8_fix_admin_capabilities() {
    if ( current_user_can( 'administrator' ) ) {
        $admin_role = get_role( 'administrator' );
        if ( $admin_role ) {
            // WooCommerce 核心权限
            $admin_role->add_cap( 'manage_woocommerce' );
            $admin_role->add_cap( 'view_admin_dashboard' );
            
            // 产品相关权限
            $admin_role->add_cap( 'edit_products' );
            $admin_role->add_cap( 'read_products' );
            $admin_role->add_cap( 'delete_products' );
            $admin_role->add_cap( 'edit_others_products' );
            $admin_role->add_cap( 'delete_others_products' );
            $admin_role->add_cap( 'publish_products' );
            $admin_role->add_cap( 'edit_published_products' );
            $admin_role->add_cap( 'delete_published_products' );
            
            // 分类权限
            $admin_role->add_cap( 'manage_product_terms' );
            $admin_role->add_cap( 'edit_product_terms' );
            $admin_role->add_cap( 'delete_product_terms' );
            $admin_role->add_cap( 'assign_product_terms' );
            
            // 添加可能缺失的权限
            $admin_role->add_cap( 'edit_shop_orders' );
            $admin_role->add_cap( 'read_shop_orders' );
            $admin_role->add_cap( 'delete_shop_orders' );
            $admin_role->add_cap( 'edit_shop_order_notes' );
            $admin_role->add_cap( 'edit_others_shop_orders' );
        }
    }
}

// 3. 安全的菜单清理 - 只隐藏，不删除
add_action( 'admin_menu', 'at8_safe_menu_cleanup', 9999 );
function at8_safe_menu_cleanup() {
    global $submenu;
    
    // 移除 WooCommerce 主菜单
    remove_menu_page( 'woocommerce' );
    
    // 清理产品菜单的子菜单
    if ( isset( $submenu['edit.php?post_type=product'] ) ) {
        foreach ( $submenu['edit.php?post_type=product'] as $key => $item ) {
            if ( isset( $item[2] ) ) {
                $remove_slugs = array(
                    'wc-admin',
                    'wc-reports',
                    'wc-settings',
                    'wc-status',
                    'wc-addons',
                    'wc-orders',
                    'shop_coupon',
                    'marketing',
                    'payments'
                );
                
                foreach ( $remove_slugs as $slug ) {
                    if ( strpos( $item[2], $slug ) !== false ) {
                        unset( $submenu['edit.php?post_type=product'][$key] );
                        break;
                    }
                }
            }
        }
    }
    
    // 移除独立支付菜单
    remove_menu_page( 'wc-admin&path=/payments' );
}

// 4. 重定向不需要的页面
add_action( 'admin_init', 'at8_safe_redirects' );
function at8_safe_redirects() {
    if ( isset( $_GET['page'] ) ) {
        $redirect_pages = array(
            'wc-orders',
            'wc-reports',
            'wc-settings',
            'wc-status',
            'wc-addons',
            'wc-admin'
        );
        
        $current_page = sanitize_text_field( $_GET['page'] );
        
        foreach ( $redirect_pages as $page ) {
            if ( $current_page === $page || strpos( $current_page, $page ) !== false ) {
                wp_redirect( admin_url( 'edit.php?post_type=product' ) );
                exit;
            }
        }
    }
}

// 5. CSS 隐藏不需要的菜单项
add_action( 'admin_head', 'at8_hide_unwanted_menus' );
function at8_hide_unwanted_menus() {
    echo '<style type="text/css">
        /* 隐藏 WooCommerce 主菜单 */
        #toplevel_page_woocommerce {
            display: none !important;
        }

            font-size: 14px !important;
        }
    </style>';
}

// 6. JavaScript 辅助隐藏
add_action( 'admin_footer', 'at8_js_cleanup' );
function at8_js_cleanup() {
    ?>
    <script type="text/javascript">
    jQuery(document).ready(function($) {

        hideUnwantedMenus();
        setInterval(hideUnwantedMenus, 1000);
    });
    </script>
    <?php
}

// 7. 移除仪表盘小工具

// 9. 禁用任务列表
