Woocommerce 中定义的产品类别中仅允许购物车中的一件商品
Allow only one item in cart from defined product categories in Woocommerce
在 Woocommerce 中,我发现了一些代码,它限制用户购买类别 a 或 b 的每个类别一个。因此,当前用户可以从 cat a 购买 2 件商品 1,从 cat b 购买 1 件。我想限制用户只能使用类别 a 或类别 b 中的一种产品。我正在使用的代码如下,在此先感谢。
add_filter( 'woocommerce_add_to_cart_validation', 'allowed_quantity_per_category_in_the_cart', 10, 2 );function allowed_quantity_per_category_in_the_cart( $passed, $product_id) {
$max_num_products = 1;// change the maximum allowed in the cart
$running_qty = 0;
$restricted_product_cats = array();
//Restrict particular category/categories by category slug
$restricted_product_cats[] = 'cat-a, cat-b';
// Getting the current product category slugs in an array
$product_cats_object = get_the_terms( $product_id, 'product_cat' );
foreach($product_cats_object as $obj_prod_cat) $current_product_cats[]=$obj_prod_cat->slug;
// Iterating through each cart item
foreach (WC()->cart->get_cart() as $cart_item_key=>$cart_item ){
// Restrict $max_num_products from each category
if( has_term( $current_product_cats, 'product_cat', $cart_item['product_id'] )) {
// Restrict $max_num_products from restricted product categories
//if( array_intersect($restricted_product_cats, $current_product_cats) && has_term( $restricted_product_cats, 'product_cat', $cart_item['product_id'] )) {
// count(selected category) quantity
$running_qty += (int) $cart_item['quantity'];
// More than allowed products in the cart is not allowed
if( $running_qty >= $max_num_products ) {
wc_add_notice( sprintf( 'Only %s '.($max_num_products>1?'products from this category are':'product from this category is').' allowed in the cart.', $max_num_products ), 'error' );
$passed = false; // don't add the new product to the cart
// We stop the loop
break;
}
}
}
return $passed;}
试试这个 (但它不处理数量,因为不清楚而且更复杂,因为在购物车页面中它们可以更改):
add_filter( 'woocommerce_add_to_cart_validation', 'limit_cart_items_from_category', 10, 3 );
function limit_cart_items_from_category ( $passed, $product_id, $quantity )
{
// Accept when cart is empty
if( WC()->cart->is_empty() ) return $passed;
// HERE your product categories in this array (can be names, slugs or Ids)
$categories = array('T-shirts', 'Hoodies');
$found = $current = false;
// Check the current product
if( has_term( $categories, 'product_cat', $product_id ) ){
$current = true;
}
// Loop through cart items checking for product categories
foreach ( WC()->cart->get_cart() as $cart_item ){
if( has_term( $categories, 'product_cat', $cart_item['product_id'] ) ) {
$found = true;
break; // stop the loop.
}
}
// Current product and a cart item match with defined product categories
if( $found && $current ){
$passed = false;
$cats_str = implode('" and "', $categories );
wc_add_notice( sprintf( __('Only one item is allowed from "%s" categories…', 'woocommerce' ), $cats_str ), 'error' );
}
return $passed;
}
代码进入您的活动子主题(或活动主题)的 function.php 文件。测试和工作。
谢谢你的代码我修改了这段代码并制作了我的自定义代码。当客户将定义类别的产品添加到购物车时,之后他们不允许购物其他类别的产品。
您只需更改数量即可轻松设置产品的最大数量。
再次感谢您。
