我需要为 WooCommerce 中的某些类别强制设置最低订单金额，因此在购物车和结帐页面中设置了提醒。
到目前为止，如果购物车中的总金额低于设置的最小金额，我设法设置了警报，但我无法创建基于类别的过滤器。实际上，任何其他产品都添加到购物车中，警报被超越，用户可以购买我想限制的那个类别的产品。
代码如下：
/**
* Set a minimum order amount for checkout
*/
add_action( 'woocommerce_checkout_process', 'wc_minimum_order_amount' );
add_action( 'woocommerce_before_cart' , 'wc_minimum_order_amount' );
add_action( 'woocommerce_before_checkout' , 'wc_minimum_order_amount' );
function wc_minimum_order_amount() {
// Set this variable to specify a minimum order value
$minimum = 30;
// set array with cat IDs
$category_ids = array( 336, 427, 433 );
// set bool that checks is minimum amount has been reached
$needs_minimum_amount = false; // Initializing
$subTotal_amount = WC()->cart->subtotal; // Items subtotal including taxes
$total_amount = WC()->cart->total; // Items subtotal excluding taxes
if ( $total_amount < $minimum ) {
// Loop through cart items
foreach ( WC()->cart->get_cart() as $cart_item ) {
$product_id = $cart_item['product_id'];
$variation_id = $cart_item['variation_id'];
// Check for matching product categories
if( sizeof($category_ids) > 0 ) {
$taxonomy = 'product_cat';
if ( has_term( $category_ids, $taxonomy, $product_id ) ) {
$needs_minimum_amount = true;
break; // Stop the loop
}
}
}
if( $needs_minimum_amount ) {
if( is_cart()) {
wc_print_notice(
sprintf( 'Your current order total is %s — you must have an order with a minimum of %s to place your order ' ,
wc_price( WC()->cart->total ),
wc_price( $minimum )
), 'error'
);
} else {
wc_add_notice(
sprintf( 'Your current order total is %s — you must have an order with a minimum of %s to place your order' ,
wc_price( WC()->cart->total ),
wc_price( $minimum )
), 'error'
);
}
}
}
}

您的代码中有一些错误……请改用以下内容：
add_action( 'woocommerce_checkout_process', 'wc_minimum_order_amount' );
add_action( 'woocommerce_before_cart', 'wc_minimum_order_amount' );
add_action( 'woocommerce_before_checkout_form', 'wc_minimum_order_amount' );
function wc_minimum_order_amount() {
$min_amount = 30; // Min subtotal required
$taxonomy = 'product_cat'; // Product category taxonomy | For product tags use 'product_tag'
$terms = array( 336, 427, 433 ); // Category terms (can be Ids, slugs, or names)
$found = false; // Initializing
$subtotal = WC()->cart->subtotal; // Incl. taxes
$total = WC()->cart->total; // Incl. taxes
if ( $total < $min_amount ) {
// Loop through cart items
foreach ( WC()->cart->get_cart() as $cart_item ) {
if ( has_term( $terms, $taxonomy, $cart_item['product_id'] ) ) {
$found = true;
break; // Stop the loop
}
if( $found ) {
$message = sprintf( 'Your current order total is %s — you must have an order with a minimum of %s to place your order ' ,
wc_price( $total ),
wc_price( $min_amount )
);
if( is_cart()) {
wc_print_notice( $message, 'error' );
} else {
wc_add_notice( $message, 'error' );
}
}
}
}
}
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。
添加：基于特定的小计，包括。税金
此代码版本基于属于特定定义类别的项目小计：
add_action( 'woocommerce_checkout_process', 'wc_minimum_order_amount' );
add_action( 'woocommerce_before_cart', 'wc_minimum_order_amount' );
add_action( 'woocommerce_before_checkout_form', 'wc_minimum_order_amount' );
function wc_minimum_order_amount() {
$min_amount = 30; // Min subtotal required
$taxonomy = 'product_cat'; // Product category taxonomy | For product tags use 'product_tag'
$terms = array( 336, 427, 433 ); // Category terms (can be Ids, slugs, or names)
$subtotal = 0; // Initializing
// Loop through cart items
foreach ( WC()->cart->get_cart() as $cart_item ) {
if ( has_term( $terms, $taxonomy, $cart_item['product_id'] ) ) {
$subtotal += $cart_item['line_subtotal'] + $cart_item['line_subtotal_tax'];
}
}
if ( $subtotal < $min_amount ) {
if( $found ) {
$message = sprintf( 'Your current order total is %s — you must have an order with a minimum of %s to place your order ' ,
wc_price( $total ),
wc_price( $min_amount )
);
if( is_cart()) {
wc_print_notice( $message, 'error' );
} else {
wc_add_notice( $message, 'error' );
}
}
}
}
它应该有效。

最后，我发现该解决方案对@LoicTheAztec 提供的代码有一点作用。
下面是最终代码。已测试并正常工作。
// Set a minimum order amount for checkout
add_action( 'woocommerce_checkout_process', 'wc_minimum_order_amount' );
add_action( 'woocommerce_before_cart' , 'wc_minimum_order_amount' );
// add_action( 'woocommerce_before_checkout' , 'wc_minimum_order_amount' );
function wc_minimum_order_amount() {
$min_amount = 30; // Set this variable to specify a minimum order value
$taxonomies = array('product_cat'); // Product category taxonomy | For product tags use 'product_tag'
$term_ids = array( 336, 427, 433 ); // Category terms (can be Ids, slugs, or names)
$found = false; // Initializing // set bool that checks if minimum amount has been reached
$subtotal = 0; // Initializing // set subtotal formed by specific category total (incl. taxes)
$subTotal_amount = WC()->cart->subtotal; // Items subtotal including taxes
$total_amount = WC()->cart->total; // Items subtotal including taxes
// 1 - Loop through cart items targeting those having that specific category
foreach ( WC()->cart->get_cart() as $cart_item ) {
if ( has_term( $term_ids, $taxonomies[0], $cart_item['product_id'] ) ) {
$subtotal += $cart_item['line_subtotal'] + $cart_item['line_subtotal_tax'];
}
}
// 2 - Check if at least one product of that category is in the cart
if($subtotal > 0){
$found = true;
}
// 2 - check if subtotal is below the min amount set
if ( $subtotal < $min_amount ) {
if( $found ) {
$message = sprintf( 'Your current order total is %s — you must have an order with a minimum of %s to place your order ' ,
wc_price( $subtotal ),
wc_price( $min_amount )
);
if( is_cart()) {
wc_print_notice( $message, 'error' );
} else {
wc_add_notice( $message, 'error' );
}
}
}
