|
|||
|
|
|
|||
|
|
## 概述
|
|||
|
|
|
|||
|
|
本指南将帮助您将现有的 YITH WooCommerce Brands Add-On 数据迁移到 WooCommerce 9.4+ 的原生品牌功能。
|
|||
|
|
|
|||
|
|
## 数据结构分析
|
|||
|
|
|
|||
|
|
### YITH WooCommerce Brands Add-On 结构
|
|||
|
|
- **分类法名称**: `yith_product_brand`
|
|||
|
|
- **数据存储**: 使用标准 WordPress 分类法表
|
|||
|
|
- `wp_terms` - 品牌名称和别名
|
|||
|
|
- `wp_term_taxonomy` - 分类法类型和描述
|
|||
|
|
- `wp_term_relationships` - 产品与品牌关联
|
|||
|
|
- `wp_termmeta` - 品牌元数据(logo、banner等)
|
|||
|
|
|
|||
|
|
### WooCommerce 原生品牌功能结构
|
|||
|
|
- **分类法名称**: `product_brand`
|
|||
|
|
- **数据存储**: 同样使用标准 WordPress 分类法表
|
|||
|
|
- **兼容性**: 与现有 WooCommerce 架构完全集成
|
|||
|
|
|
|||
|
|
## 迁移方案
|
|||
|
|
|
|||
|
|
### 方案一:使用提供的 PHP 迁移脚本
|
|||
|
|
|
|||
|
|
1. **上传脚本**
|
|||
|
|
```bash
|
|||
|
|
# 将 migrate-yith-brands.php 上传到 WordPress 根目录
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
2. **执行迁移**
|
|||
|
|
```bash
|
|||
|
|
# 方法1:浏览器访问
|
|||
|
|
http://yoursite.com/migrate-yith-brands.php
|
|||
|
|
|
|||
|
|
# 方法2:WP-CLI 执行
|
|||
|
|
wp eval-file migrate-yith-brands.php
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
3. **验证结果**
|
|||
|
|
- 检查 WooCommerce > 产品 > 品牌 页面
|
|||
|
|
- 确认品牌数据正确显示
|
|||
|
|
- 验证产品页面品牌关联
|
|||
|
|
|
|||
|
|
### 方案二:手动 SQL 迁移
|
|||
|
|
|
|||
|
|
```sql
|
|||
|
|
-- 1. 更新分类法名称
|
|||
|
|
UPDATE wp_term_taxonomy
|
|||
|
|
SET taxonomy = 'product_brand'
|
|||
|
|
WHERE taxonomy = 'yith_product_brand';
|
|||
|
|
|
|||
|
|
-- 2. 刷新 WordPress 缓存
|
|||
|
|
-- 需要在 WordPress 后台或通过代码执行
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 方案三:使用 WP-CLI(推荐)
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
# 预览迁移(不执行实际操作)
|
|||
|
|
wp eval-file wp-cli-migrate-brands.php --dry-run=true
|
|||
|
|
|
|||
|
|
# 执行迁移
|
|||
|
|
wp eval-file wp-cli-migrate-brands.php
|
|||
|
|
|
|||
|
|
# 迁移并清理旧数据
|
|||
|
|
wp eval-file wp-cli-migrate-brands.php --cleanup=true
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 迁移步骤详解
|
|||
|
|
|
|||
|
|
### 1. 备份数据库
|
|||
|
|
```bash
|
|||
|
|
# 使用 mysqldump 备份
|
|||
|
|
mysqldump -u username -p database_name > backup_before_migration.sql
|
|||
|
|
|
|||
|
|
# 或使用 WP-CLI
|
|||
|
|
wp db export backup_before_migration.sql
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 2. 检查当前品牌数据
|
|||
|
|
```sql
|
|||
|
|
-- 查看现有品牌数量
|
|||
|
|
SELECT COUNT(*) FROM wp_term_taxonomy WHERE taxonomy = 'yith_product_brand';
|
|||
|
|
|
|||
|
|
-- 查看品牌名称
|
|||
|
|
SELECT t.name, t.slug, tt.description, tt.count
|
|||
|
|
FROM wp_terms t
|
|||
|
|
JOIN wp_term_taxonomy tt ON t.term_id = tt.term_id
|
|||
|
|
WHERE tt.taxonomy = 'yith_product_brand';
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 3. 启用 WooCommerce 原生品牌功能
|
|||
|
|
|
|||
|
|
在 `functions.php` 中添加:
|
|||
|
|
```php
|
|||
|
|
// 启用 WooCommerce 原生品牌功能
|
|||
|
|
add_action('init', function() {
|
|||
|
|
if (class_exists('WooCommerce')) {
|
|||
|
|
// 注册品牌分类法
|
|||
|
|
register_taxonomy('product_brand', 'product', [
|
|||
|
|
'labels' => [
|
|||
|
|
'name' => '品牌',
|
|||
|
|
'singular_name' => '品牌',
|
|||
|
|
'menu_name' => '品牌',
|
|||
|
|
],
|
|||
|
|
'public' => true,
|
|||
|
|
'show_ui' => true,
|
|||
|
|
'show_in_menu' => true,
|
|||
|
|
'show_admin_column' => true,
|
|||
|
|
'hierarchical' => true,
|
|||
|
|
'rewrite' => ['slug' => 'product-brand'],
|
|||
|
|
'show_in_rest' => true,
|
|||
|
|
]);
|
|||
|
|
}
|
|||
|
|
});
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 4. 执行迁移
|
|||
|
|
|
|||
|
|
选择上述任一方案执行迁移。
|
|||
|
|
|
|||
|
|
### 5. 更新主题模板
|
|||
|
|
|
|||
|
|
如果主题中有自定义的品牌显示代码,需要更新:
|
|||
|
|
|
|||
|
|
```php
|
|||
|
|
// 旧代码
|
|||
|
|
$brands = get_the_terms($product_id, 'yith_product_brand');
|
|||
|
|
|
|||
|
|
// 新代码
|
|||
|
|
$brands = get_the_terms($product_id, 'product_brand');
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 6. 测试验证
|
|||
|
|
|
|||
|
|
- [ ] 品牌页面正常显示
|
|||
|
|
- [ ] 产品页面品牌信息正确
|
|||
|
|
- [ ] 品牌筛选功能正常
|
|||
|
|
- [ ] 品牌 logo 和描述正确显示
|
|||
|
|
- [ ] SEO URL 正常工作
|
|||
|
|
|
|||
|
|
## 注意事项
|
|||
|
|
|
|||
|
|
### 兼容性检查
|
|||
|
|
- 确保 WooCommerce 版本 ≥ 9.4
|
|||
|
|
- 检查主题是否支持原生品牌功能
|
|||
|
|
- 验证相关插件兼容性
|
|||
|
|
|
|||
|
|
### 数据完整性
|
|||
|
|
- 迁移前后品牌数量应一致
|
|||
|
|
- 产品关联关系应保持不变
|
|||
|
|
- 品牌元数据(logo、描述等)应完整迁移
|
|||
|
|
|
|||
|
|
### 性能优化
|
|||
|
|
```php
|
|||
|
|
// 迁移后清理缓存
|
|||
|
|
wp_cache_flush();
|
|||
|
|
delete_option('_transient_wc_attribute_taxonomies');
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 回滚方案
|
|||
|
|
|
|||
|
|
如果迁移出现问题,可以通过以下方式回滚:
|
|||
|
|
|
|||
|
|
```sql
|
|||
|
|
-- 恢复原分类法名称
|
|||
|
|
UPDATE wp_term_taxonomy
|
|||
|
|
SET taxonomy = 'yith_product_brand'
|
|||
|
|
WHERE taxonomy = 'product_brand';
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
或直接恢复数据库备份:
|
|||
|
|
```bash
|
|||
|
|
mysql -u username -p database_name < backup_before_migration.sql
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 常见问题
|
|||
|
|
|
|||
|
|
### Q: 迁移后品牌页面显示 404
|
|||
|
|
**A**: 需要刷新固定链接设置
|
|||
|
|
```bash
|
|||
|
|
wp rewrite flush
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### Q: 品牌 logo 丢失
|
|||
|
|
**A**: 检查 termmeta 表中的元数据是否正确迁移
|
|||
|
|
```sql
|
|||
|
|
SELECT * FROM wp_termmeta WHERE meta_key LIKE '%brand%';
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### Q: 产品页面不显示品牌
|
|||
|
|
**A**: 检查主题模板是否使用了正确的分类法名称
|
|||
|
|
|
|||
|
|
## 后续维护
|
|||
|
|
|
|||
|
|
### 禁用 YITH 插件
|
|||
|
|
迁移成功后,可以安全禁用 YITH WooCommerce Brands Add-On 插件。
|
|||
|
|
|
|||
|
|
### 清理旧数据
|
|||
|
|
```sql
|
|||
|
|
-- 删除旧的分类法数据(谨慎操作)
|
|||
|
|
DELETE FROM wp_term_taxonomy WHERE taxonomy = 'yith_product_brand';
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 更新相关代码
|
|||
|
|
检查并更新所有使用 `yith_product_brand` 的代码为 `product_brand`。
