[英]Auto add a product for cart item from specific product categories in WooCommerce
I have a code to add a product (a deposit) automatically to a customers cart, no matter what product he has chosen - with the code below inside the functions.php.我有一个代码可以自动将产品(存款)添加到客户的购物车,无论他选择了什么产品 - 在函数中使用下面的代码。php。 This works fine.这很好用。
But now, how to extend the code that this product will only be automatically added to the cart when the customer has chosen a product from a specific product category?但是现在,如何扩展只有当客户从特定产品类别中选择产品时,该产品才会自动添加到购物车的代码? Eg the deposit shouldn't be added to the cart when a customer buys a gift card.例如,当客户购买礼品卡时,押金不应添加到购物车中。
Thanks a lot!非常感谢!
/**
* Automatically adds product to cart on visit
*/
add_action( 'template_redirect', 'add_product_to_cart' );
function add_product_to_cart() {
if ( ! is_admin() ) {
$product_id = 1267; //product added automatically
$found = false;
//check if product already in cart
if ( sizeof( WC()->cart->get_cart() ) > 0 ) {
foreach ( WC()->cart->get_cart() as $cart_item_key => $values ) {
$_product = $values['data'];
if ( $_product->get_id() == $product_id )
$found = true;
}
// if product not found, add it
if ( ! $found )
WC()->cart->add_to_cart( $product_id );
} else {
}
}
}
You will have to use the Wordpress conditional function hast_term()
in a completely different way.您将不得不以完全不同的方式使用 Wordpress 条件 function hast_term()
。
The following code will auto add to cart a pre-defined product, if a product from a product category is already in cart:如果产品类别中的产品已在购物车中,以下代码将自动将预定义产品添加到购物车:
add_action( 'woocommerce_before_calculate_totals', 'auto_add_item_based_on_product_category', 10, 1 );
function auto_add_item_based_on_product_category( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
return;
$required_categories = array('t-shirts'); // Required product category(ies)
$added_product_id = 1267; // Specific product to be added automatically
$matched_category = false;
// Loop through cart items
foreach ( $cart->get_cart() as $item_key => $item ) {
// Check for product category
if( has_term( $required_categories, 'product_cat', $item['product_id'] ) ) {
$matched_category = true;
}
// Check if specific product is already auto added
if( $item['data']->get_id() == $added_product_id ) {
$saved_item_key = $item_key; // keep cart item key
}
}
// If specific product is already auto added but without items from product category
if ( isset($saved_item_key) && ! $matched_category ) {
$cart->remove_cart_item( $saved_item_key ); // Remove specific product
}
// If there is an item from defined product category and specific product is not in cart
elseif ( ! isset($saved_item_key) && $matched_category ) {
$cart->add_to_cart( $added_product_id ); // Add specific product
}
}
Code goes in functions.php file of your active child theme (or active theme).代码进入您的活动子主题(或活动主题)的 functions.php 文件。 Tested and works.测试和工作。
