问题描述
我试图在我的网站的购物车页面上显示一条警告消息,管理 2 个不同类别的 2 个不同数量的倍数。
类别是:
- Birre 33 cL(slug:birre-33-cl ID:187),用于多个 6 件
- Birre 75 cL(slug:birre-75-cl ID:188)用于多个数量的 12
我需要分别统计和管理(你可以买12/24/36...瓶33cL和6/12/18...瓶75cL,但不能买6瓶33cL和6瓶一瓶 75 升)。
//FILL THE Box BIRRE 33 CL
function has_product_category( $product_id,$category_ids ) {
$term_ids = array();
// Loop through the current product category terms to get only parent main category term
foreach( get_the_terms( $product_id,'product_cat' ) as $term ){
if( $term->parent > 0 ){
$term_ids[] = $term->parent; // Set the parent product category
$term_ids[] = $term->term_id;
} else {
$term_ids[] = $term->term_id;
}
}
return array_intersect( $category_ids,array_unique($term_ids) );
}
add_action( 'woocommerce_check_cart_items','woocommerce_check_cart_quantities' );
function woocommerce_check_cart_quantities() {
$multiples = 12;
$total_products = 0;
$category_ids = array( 187 );
$found = false;
foreach ( WC()->cart->get_cart() as $cart_item ) {
if ( has_product_category( $cart_item['product_id'],$category_ids ) ) {
$total_products += $cart_item['quantity'];
$found = true;
}
}
if ( ( $total_products % $multiples ) > 0 && $found )
wc_add_notice( sprintf( __('FILL YOUR 33 cL Box: you have to buy multiples of %s.','woocommerce','woocommerce'),$multiples ),'error' );
}
不幸的是,我无法管理 2 个不同的类别,每个类别显示不同的消息。
感谢任何帮助。
解决方法
更新
以下将处理具有不同倍数的 2 个不同类别数组:
add_action( 'woocommerce_check_cart_items','woocommerce_check_cart_quantities' );
function woocommerce_check_cart_quantities() {
$term_names_1 = array('Birre 75 cL'); // 1st array of term names
$term_names_2 = array('Birre 33 cL'); // 2nd array of term names
$multiples_6 = 6; // 1st multiples (for 75 cl)
$multiples_12 = 12; // 2nd multiples (for 33 cl)
$total_products_1 = $total_products_2 = 0; // Initializing
// Loop through cart items
foreach ( WC()->cart->get_cart() as $cart_item ) {
// count items | 75 cl (by 6)
if ( has_product_categories( $cart_item['product_id'],$term_names_1 ) ) {
$total_products_1 += $cart_item['quantity'];
}
// count items | 33 cl (by 12)
elseif ( has_product_categories( $cart_item['product_id'],$term_names_2 ) ) {
$total_products_2 += $cart_item['quantity'];
}
}
// Notice for 75 cl (by 6)
if ( $total_products_1 > 0 && ( $total_products_1 % $multiples_6 ) > 0 ) {
wc_add_notice( sprintf(
__('You need to buy in quantities of %s items from %s %s'),$multiples_6,explode(',',$term_names_1),_n('category','categories',count($multiples_6))
),'error' );
}
// Notice for 33 cl (by 12)
if ( $total_products_2 > 0 && ( $total_products_2 % $multiples_12 ) > 0 ) {
wc_add_notice( sprintf(
__('You need to buy in quantities of %s items from %s %s'),$multiples_12,$term_names_2),count($multiples_12))
),'error' );
}
}
// Custom conditional function that handle parent product categories too
function has_product_categories( $categories,$product_id = 0 ) {
$parent_term_ids = $categories_ids = array(); // Initializing
$taxonomy = 'product_cat';
$product_id = $product_id == 0 ? get_the_id() : $product_id;
if( is_string( $categories ) ) {
$categories = (array) $categories; // Convert string to array
}
// Convert categories term names and slugs to categories term ids
foreach ( $categories as $category ){
$result = (array) term_exists( $category,$taxonomy );
if ( ! empty( $result ) ) {
$categories_ids[] = reset($result);
}
}
// Loop through the current product category terms to get only parent main category term
foreach( get_the_terms( $product_id,$taxonomy ) as $term ){
if( $term->parent > 0 ){
$parent_term_ids[] = $term->parent; // Set the parent product category
$parent_term_ids[] = $term->term_id; // (and the child)
} else {
$parent_term_ids[] = $term->term_id; // It is the Main category term and we set it.
}
}
return array_intersect( $categories_ids,array_unique($parent_term_ids) ) ? true : false;
}
代码位于活动子主题(或活动主题)的functions.php 文件中。它应该可以工作。
