允许在Woocommerce中为特定产品类别添加到购物车最多3个产品 [英] Allow add to cart 3 products max for a specific product category in Woocommerce

问题描述

我正尝试向客户免费提供最多3个免费样品.

I am trying to send out a maximum of 3 free samples to customers with free shipping.

我创建了一些定价为0的产品，并将其设置为样品"产品类别.

I have created some 0 priced product and set them in "samples" product category.

此特定产品具有单独出售"的选项，因此客户只能在每个样本中拥有一个.

This specific products have option "sold individually" so customers can only have one of each sample.

我无法弄清楚如何最多只允许购物车中此产品类别中的3个样品产品.

I cannot figure out how to allow only a maximum of 3 samples products from this product category on cart.

感谢您的帮助.

推荐答案

使用 woocommerce_add_to_cart_validation 操作挂钩可以轻松完成此操作，以将样品"产品类别中的客户限制为最多3个项目，这方式:

This can be done easily using woocommerce_add_to_cart_validation action hook to limit customers to a maximum of 3 items from "sample" product category, this way:

add_action('woocommerce_add_to_cart_validation', 'max_3_items_for_samples', 20, 3 );
function max_3_items_for_samples( $passed, $product_id, $quantity ) {
    // HERE define your product category ID, slug or name.
    $category = 'clothing';
    $limit = 3; // HERE set your limit
    $count = 0;

    // Loop through cart items checking for specific product categories
    foreach ( WC()->cart->get_cart() as $cat_item ) {
        if( has_term( $category, 'product_cat', $cat_item['product_id'] ) )
            $count++;
    }
    if( has_term( $category, 'product_cat', $product_id ) && $count == $limit )
        $count++;

    // Total item count for the defined product category is more than 3
    if( $count > $limit ){
        // HERE set the text for the custom notice
        $notice = __('Sorry, you can not add to cart more than 3 free samples.', 'woocommerce');
        // Display a custom notice
        wc_add_notice( $notice, 'error' );
        // Avoid adding to cart
        $passed = false;
    }

    return $passed;
}

代码进入活动的子主题(或主题)的function.php文件中.

经过测试，可以正常工作.

Tested and works.
