foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
// if a product is not in our category, bail out since we know the category is not alone
if ( ! has_term( $category, 'product_cat', $cart_item['data']->id ) ) {
return false;
}
}
// if we're here, all items in the cart are in our category
return true;
}
但我有一个问题:当购物车只包含来自其他产品类别的商品时,它不允许继续结帐并显示错误消息
恢复:
非常感谢您的帮助。请尝试以下代码,该代码不允许将您的“测试”定义的产品类别与其他产品类别混合,显示错误通知并避免签出:
add_action( 'woocommerce_check_cart_items', 'prevent_checkout_product_category_based' );
function prevent_checkout_product_category_based() {
// HERE set the product category slug
$category = 'test';
$found = $other = false; // Initializing variables
// Loop through cart items
foreach ( WC()->cart->get_cart() as $cart_item ) {
// checking for the specific product category
$term_slugs = wp_get_post_terms( $cart_item['product_id'], 'product_cat', array('fields' => 'slugs') );
if( in_array($category, $term_slugs) ) {
$found = true; // Targeted product category found
}
elseif( ! in_array($category, $term_slugs) && sizeof($term_slugs) > 0 ){
$other = true; // Other product categories found
}
}
// If the targeted product category is mixed with other product categories
if ( $found && $other ) {
// Display an error notice and avoid checkout
wc_add_notice( __( "The cart contains products from PREORDER and ONHAND categories and can't be mixed together, to allow checkout." ), 'error' );
}
}
代码进入活动子主题(或活动主题)的function.php文件。测试和工作
