[英]how to get particular product quantity from the cart page in the woocommerce
With this code:使用此代码:
foreach ( WC()->cart->get_cart() as $cart_item ) {
$quantity = $cart_item['quantity'];
echo $quantity;
}
I can get the quantity of all the products added in cart but I need it for the particular product.我可以获得添加到购物车中的所有产品的数量,但我需要特定产品的数量。
You can loop through cart items to get the quantity for a specific product id as follows:您可以遍历购物车项目以获取特定产品 ID 的数量,如下所示:
// Set here your product ID (or variation ID)
$targeted_id = 24;
// Loop through cart items
foreach ( WC()->cart->get_cart() as $cart_item ) {
if( in_array( $targeted_id, array($cart_item['product_id'], $cart_item['variation_id']) ){
$quantity = $cart_item['quantity'];
break; // stop the loop if product is found
}
}
// Displaying the quantity if targeted product is in cart
if( isset( $quantity ) && $quantity > 0 ) {
printf( '<p>' . __("Quantity for Product ID %d is: %d") . '</p>, $targeted_id, $quantity );
}
Or you can also use the WC_Cart
method get_cart_item_quantities()
as follow:或者您也可以使用WC_Cart
方法get_cart_item_quantities()
如下:
// Set here your product ID (or variation ID)
$targeted_id = 24;
// Get quantities for each item in cart (array of product id / quantity pairs)
$quantities = WC()->cart->get_cart_item_quantities();
// Displaying the quantity if targeted product is in cart
if( isset($quantities[$targeted_id]) && $quantities[$targeted_id] > 0 ) {
printf( '<p>' . __("Quantity for Product ID %d is: %d") . '</p>, $targeted_id, $quantities[$targeted_id] );
}
Note: This last way doesn't allow to target the parent variable product.注意:最后一种方法不允许定位父变量产品。
global $woocommerce;
$items = $woocommerce->cart->get_cart();
foreach($items as $item => $values) {
$_product = $values['data']->post;
echo "<b>".$_product->post_title.'</b> <br> Quantity: '.$values['quantity'].'<br>';
$price = get_post_meta($values['product_id'] , '_price', true);
echo " Price: ".$price."<br>";
}
$cart = WC()->cart->get_cart();
$product_cart_id = WC()->cart->generate_cart_id( $product->get_id() );
if( WC()->cart->find_product_in_cart( $product_cart_id )) {
echo($cart[$product_cart_id]['quantity']);
}
Try this :试试这个:
<?php
global $woocommerce;
$items = $woocommerce->cart->get_cart();
foreach($items as $item => $values) {
$_product = $values['data']->post;
echo "<b>".$_product->post_title.'</b> <br> Quantity: '.$values['quantity'].'<br>';
$price = get_post_meta($values['product_id'] , '_price', true);
echo " Price: ".$price."<br>";
}
?>
1) Make a child theme 1)制作儿童主题
2) Create a file named functions.php with this code : 2)使用以下代码创建一个名为functions.php的文件:
<?php
if( !function_exists('in_cart_product_quantity') ) {
function in_cart_product_quantity( $atts ) {
$atts = shortcode_atts(array('id' => ''), $atts, 'product_qty'); // shortcode attributes
if( empty($atts['id'])) return; // check id not null
if ( WC()->cart ) { // check cart exists
$qty = 0; // init qty
foreach (WC()->cart->get_cart() as $cart_item) {
if($cart_item['product_id'] == $atts['id']) {
$qty = $cart_item['quantity'];
break; // stop the loop if product is found
}
}
return $qty;
}
return;
}
add_shortcode( 'product_qty', 'in_cart_product_quantity' );
}
3) Use the shortcode : 3)使用简码:
[product_qty id="xxx"]
(Change xxx with id of the product you want to know the quantity in cart) (用您想知道购物车数量的产品的id更改xxx)

WC_Cart::get_cart_item_quantities() – Get cart items quantities
$product_id
通过$product_id
// Your product ID
$product_id = 30;
// Get cart items quantities
$cart_item_quantities = WC()->cart->get_cart_item_quantities();
// Product quantity in cart - All PHP versions
$product_qty_in_cart = isset( $cart_item_quantities[ $product_id ] ) ? $cart_item_quantities[ $product_id ] : null;
// Product quantity in cart - Same as the previous one with PHP 7
$product_qty_in_cart = $cart_item_quantities[ $product_id ] ?? null;
// Result
echo $product_qty_in_cart;
$product
通过$product
// Product
global $product;
// Get cart items quantities
$cart_item_quantities = WC()->cart->get_cart_item_quantities();
// Product quantity in cart
$product_qty_in_cart = $cart_item_quantities[ $product->get_stock_managed_by_id() ];
// Result
echo $product_qty_in_cart;
