标签： php wordpress woocommerce hook product

我有一家商店，每个类别中的商品超过30,000，并且我希望每个类别中的商品展示数量只能限制1000，以提高加载速度。其余产品只能通过搜索找到。

我该怎么做？

如果你不想做的自定义代码，然后用户的插件称为负载更多产品WooCommerce。

通过AJAX从下一个页面加载产品具有无限滚动或负载更多的产品按钮

功能：

✅WooCommerce产品的无限滚动

✅加载更多产品按钮或AJAX分页

✅自定义按钮文字

✅用于自定义代码的JavaScript钩子

您可以使用post_limits挂钩限制产品类别归档页面上显示的产品总数：

add_filter( 'post_limits', 'product_category_archives_limit', 10, 2 );
function product_category_archives_limit( $limit, $query ) {
    if ( is_product_category() ) {
        $limit = 'LIMIT 1000';
    }
    return $limit;
}

代码进入您的活动子主题（或活动主题）的function.php文件中。经过测试，可以正常工作。
