一键清空WooCommerce指定分类的所有产品代码

在 WooCommerce 中“一键清空指定分类的所有产品”，你可以使用以下 PHP 代码实现此功能

// 1. 先定义删除函数
function delete_all_products_in_category($category_slug_or_id) {
    $args = [
        'post_type'      => 'product',
        'posts_per_page' => -1,
        'post_status'    => 'any',
        'tax_query' => [
            [
                'taxonomy' => 'product_cat',
                'field'    => is_numeric($category_slug_or_id) ? 'term_id' : 'slug',
                'terms'    => $category_slug_or_id,
            ]
        ]
    ];

    $products = get_posts($args);
    $deleted = 0;

    foreach ($products as $product) {
        wp_delete_post($product->ID, true); // 强制永久删除
        $deleted++;
    }

    return $deleted;
}

// 2. 添加菜单
add_action('admin_menu', function() {
    add_submenu_page(
        'woocommerce',
        '清空商品分类',
        '清空商品分类',
        'manage_woocommerce',
        'delete-products-by-category',
        'render_delete_products_page'
    );
});

// 3. 渲染页面，使用上面定义的函数
function render_delete_products_page() {
    $deleted_count = null;

    if (isset($_POST['product_cat_slug'])) {
        $cat = sanitize_text_field($_POST['product_cat_slug']);
        $deleted_count = delete_all_products_in_category($cat);
    }

    ?>
    <div class="wrap">
        <h1>清空 WooCommerce 分类商品</h1>
        <form method="post">
            <p>
                <label for="product_cat_slug">输入分类 Slug 或 ID：</label><br>
                <input type="text" name="product_cat_slug" id="product_cat_slug" style="width:300px;" required>
            </p>
            <p>
                <button class="button button-primary" type="submit">立即删除该分类下所有商品</button>
            </p>
        </form>
        <?php if (!is_null($deleted_count)) : ?>
            <div style="margin-top:20px;">
                ✅ 共删除了 <strong><?php echo $deleted_count; ?></strong> 个商品。
            </div>
        <?php endif; ?>
    </div>
    <?php
}
