問題描述
在 WooCommerce 中，我需要為產品類別的每個項目設置最小數量.我搜索了論壇，發現了一些運行良好的代碼，但它只計算產品類別的總數量:
In WooCommerce, I need to set up a minimum quantity for each item of a product category. I searched the forum and found some code that works fine except it only counts the Quantity for a product category in total:
add_action( 'woocommerce_checkout_process', 'wc_minimum_order_amount' );
add_action( 'woocommerce_before_cart' , 'wc_minimum_order_amount' );
function wc_minimum_order_amount() {
$minimum = 5; //Qty product
if ( WC()->cart->cart_contents_count < $minimum ) {
$draught_links = array();
foreach(WC()->cart->get_cart() as $cart_item_key => $values ) {
$_product = $values['data'];
$terms = get_the_terms( $_product->id, 'product_cat' );
foreach ($terms as $term) {
$draught_links[] = $term->name;
}
}
if (in_array("Noten", $draught_links)){
$on_draught = true;
}else{
$on_draught = false;
}
if( is_cart() ) {
if($on_draught){
wc_print_notice(
sprintf( 'Bitte beachte die Mindestbestellmenge. Du brauchst mindestens %s Notenexemplare pro Arrangement. Aktuell hast du %s Stück in deinem Warenkorb.' ,
$minimum ,
WC()->cart->cart_contents_count
), 'error'
);
}
} else {
if($on_draught){
wc_add_notice(
sprintf( 'Bitte beachte die Mindestbestellmenge. Du brauchst mindestens %s Notenexemplare pro Arrangement. Aktuell hast du %s Stück in deinem Warenkorb.' ,
$minimum ,
WC()->cart->cart_contents_count
), 'error'
);
}
}
}
}
例如，如果我有兩個屬于同一產品類別的產品(A 和 B)并將此類別的最小數量設置為 5，則在這種情況下不會出現客戶的錯誤消息:
For example if I have two products (A and B) of belonging to the same product category and set up minimum quantity for this category to 5, the error message for the customer won't appear in this case:
- 產品 A:3
- 產品 B:2
對于該類別的每個產品，我至少需要 5 個.
I need a min quantity of 5 for every single product of that category.
您知道如何更改和優化以下代碼嗎?
Do you have an idea how to change and optimize the following code?
推薦答案
從 WooCommerce 3 開始，您的實際代碼已經過時且不方便……有多種方法:
Since WooCommerce 3, your actual code is outdated and not convenient… There is multiple ways:
1).最好的方法:在產品級別設置最小數量(針對產品類別):
1). The best way: Set up the minimum quantity at product level (for a product category):
// On single product pages
add_filter( 'woocommerce_quantity_input_args', 'min_qty_filter_callback', 20, 2 );
function min_qty_filter_callback( $args, $product ) {
$categories = array('Noten'); // The targeted product category(ies)
$min_qty = 5; // The minimum product quantity
$product_id = $product->is_type('variation') ? $product->get_parent_id() : $product->get_id();
if( has_term( $categories, 'product_cat', $product_id ) ){
$args['min_value'] = $min_qty;
}
return $args;
}
// On shop and archives pages
add_filter( 'woocommerce_loop_add_to_cart_args', 'min_qty_loop_add_to_cart_args', 10, 2 );
function min_qty_loop_add_to_cart_args( $args, $product ) {
$categories = array('Noten'); // The targeted product category
$min_qty = 5; // The minimum product quantity
$product_id = $product->get_id();
if( has_term( $categories, 'product_cat', $product_id ) ){
$args['quantity'] = $min_qty;
}
return $args;
}
代碼位于活動子主題(或活動主題)的 functions.php 文件中.經過測試和工作.
Code goes in functions.php file of your active child theme (or active theme). Tested and work.
2).替代方法:檢查購物車商品并顯示錯誤消息(類似于您的代碼):
2). Alternative way: Checking cart items and displaying an error message (similar to your code):
add_action( 'woocommerce_check_cart_items', 'wc_min_item_required_qty' );
function wc_min_item_required_qty() {
$categories = array('Noten'); // The targeted product category
$min_item_qty = 5; // Minimum Qty required (for each item)
$display_error = false; // Initializing
// Loop through cart items
foreach(WC()->cart->get_cart() as $cart_item ) {
$item_quantity = $cart_item['quantity']; // Cart item quantity
$product_id = $cart_item['product_id']; // The product ID
// For cart items remaining to "Noten" producct category
if( has_term( $categories, 'product_cat', $product_id ) && $item_quantity < $min_item_qty ) {
wc_clear_notices(); // Clear all other notices
// Add an error notice (and avoid checkout).
wc_add_notice( sprintf( 'Bitte beachte die Mindestbestellmenge. Du brauchst mindestens %s Notenexemplare pro Arrangement. Aktuell hast du %s Stück in deinem Warenkorb.', $min_item_qty , $item_quantity ), 'error' );
break; // Stop the loop
}
}
}

為了使其也適用于父產品類別，您還將添加此自定義功能:
To make it work for parent product category too, you will also add this custom function:
// 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;
}
代碼位于活動子主題(或活動主題)的 functions.php 文件中.經過測試和工作.
Code goes in functions.php file of your active child theme (or active theme). Tested and work.
然后在現有代碼中，您將替換:
Then in the existing code, you will replace:
has_term( $category, 'product_cat', $product_id )
由
has_product_categories( $category, $product_id )
這也將允許您處理父產品類別.
That will allow you to handle parent product categories too.
