对未登录的用户隐藏产品(使用标签)? [英] hide products from users who are not logged in (using tags)?

问题描述

非常简单的概念......如果用户未登录，我想在 WooCommerce 的任何地方隐藏所有带有批发"标签的产品......我已经接近了，但还没有骰子.

Pretty simple concept... I want to hide all products that have the tag "Wholesale" from everywhere in WooCommerce if the user is not logged in... I have gotten close, but no dice just yet.

我目前拥有什么

$product_tags = wp_get_post_terms( $product->id, 'product_tag' );

if ( ! empty( $product_tags ) ) {
    foreach( $product_tags as $tag ) {
        if ( $tag->slug === 'wholesale' && ! is_user_logged_in() ) {
            return;
        }
    }
}

从结果中可以看出，产品网格中存在漏洞，因为该行应该在产品 1/3(每行)和 上具有类 .first.last 项目 3/3.我目前正在删除"产品的地方显然是在计算每行项目然后分配所述类的逻辑之后.

As you can see from the results, there are holes in the product grid because the row is supposed to have the class .first on product 1/3 (on each row) and .last on item 3/3. Where I am currently "removing" the product is apparently after the logic that counts the items per row and then assigns said classes.

这个片段并没有做我想做的一切.简而言之，我想尽快从 products 数组中删除产品(在我的主题可以开始构建其元素之前).我还想在直接访问产品页面时隐藏所有产品信息(虽然可能是一个不同的问题).

This snippet does not do everything I would like. In a nutshell, I would like to remove the product from the products array as soon as possible (before my theme can start constructing its elements). I would also like to hide all product information when the product page is accessed directly (probably a different question though).

那么，是否有一个 WooCommerce 挂钩可以在显示产品的任何地方运行?如果有，我该如何使用该挂钩隐藏带有批发"标签的产品?

So, is there a WooCommerce hook that runs everywhere products are displayed, and if so, how can I hide the products that have the tag of "Wholesale" using that hook?

推荐答案

最好使用 pre_get_posts

这里...

function rei_exclude_by_product_tag( $query ) {
    if ( $query->is_main_query() && is_woocommerce() && !is_user_logged_in() ) {
        $taxquery = array(
            array(
                    'taxonomy' => 'product_tag',
                    'field' => 'id',
                    'terms' => array( 6 ), // the ID of the product tag
                    'operator'=> 'NOT IN' // exclude
                )
            );

        $query->set('tax_query', $taxquery);
    }
}
add_action( 'pre_get_posts', 'rei_exclude_by_product_tag' );
