[英]Allow only one item in cart from defined product categories in Woocommerce
In Woocommerce, I found a bit of code that restricts a users purchase to one per category for category a or b.在 Woocommerce 中,我发现了一些代码,将用户购买限制为类别 a 或 b 的每个类别。 So currently the user could purchase 2 items 1 from cat a and 1 from cat b.
所以目前用户可以从猫 a 购买 2 件商品 1,从猫 b 购买 1 件。 I would like to limit the user to only one product from category a or b.
我想限制用户只能使用 a 类或 b 类中的一种产品。 The code I am working with is below, thanks in advance.
我正在使用的代码如下,提前致谢。
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;}
Try this (but it doesn't handle quantities as is not clear and much more complicated, because in cart page they can be altered) :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被更改) :
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;
}
Code goes in function.php file of your active child theme (or active theme).代码位于活动子主题(或活动主题)的 function.php 文件中。 Tested and work.
测试和工作。
Thank You For your Code I modified this code and make my customized code.谢谢你的代码我修改了这个代码并制作了我的自定义代码。 when customer add to cart the product from defined category, after that they didnt allow to cart other category product.
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。 you can set the maximum number of product easily by just changing the number.
您只需更改数量即可轻松设置产品的最大数量。 Thank You once again.
再一次谢谢你。
