I have 3 ticket products in WooCommerce and want to add a name field per ticket product purchased - so if a customer buys three tickets 3 name fields are displayed to fill out in the checkout.
The code below works:
// Custom WooCommerce Checkout Fields based on Quantity
add_action( 'woocommerce_before_order_notes', 'person_details' );
function person_details($checkout) {
global $woocommerce;
$count = WC()->cart->get_cart_contents_count();
$i = 1;
for($k=2; $k<= $count; $k ) {
$i ;
print ('<h3>Please enter details of attendee '.$i.'</h3>');
woocommerce_form_field( 'cstm_full_name'.$i, array(
'type' => 'text',
'class' => array('my-field-class form-row-wide'),
'label' => __('Full name'),
'placeholder' => __('Enter full name'),
),
$checkout->get_value( 'cstm_full_name'.$i ));
echo '<div ></div>';
}
}
But this includes all products added to cart - how can I target specific Product IDs to be only be part of the cart count?
$count = WC()->cart->get_cart_contents_count();
CodePudding user response:
As an alternative and most recommended way, you can use WC_Cart::get_cart_item_quantities() and in_array() in your callback function to get the cart item quantity from specific product IDs in cart
So you get:
function action_woocommerce_before_order_notes( $checkout ) {
// True
if ( WC()->cart ) {
// Specific product IDs
$product_ids = array( 30, 823, 53, 57 );
// Initialize
$count = 0;
// Loop trough cart items quantities
foreach ( WC()->cart->get_cart_item_quantities() as $product_id => $cart_item_quantity ) {
// Checks if a value exists in an array
if ( in_array( $product_id, $product_ids ) ) {
$count = $cart_item_quantity;
}
}
// Result
echo '<p style="color: red; font-size: 25px;">Count = ' . $count . '</p>';
}
}
add_action( 'woocommerce_before_order_notes', 'action_woocommerce_before_order_notes', 10, 1 );
OR
You could use the woocommerce_cart_contents_count
filter hook,
which allows you to customize the get_cart_contents_count()
function to your needs:
function filter_woocommerce_cart_contents_count( $array_sum ) {
// True
if ( WC()->cart ) {
// Specific product IDs
$product_ids = array( 30, 823, 53, 57 );
// Loop trough cart items quantities
foreach ( WC()->cart->get_cart_item_quantities() as $product_id => $cart_item_quantity ) {
// Checks if a value NOT exists in an array
if ( ! in_array( $product_id, $product_ids ) ) {
$array_sum -= $cart_item_quantity;
}
}
}
return $array_sum;
}
add_filter( 'woocommerce_cart_contents_count', 'filter_woocommerce_cart_contents_count', 10, 1 );
function action_woocommerce_before_order_notes( $checkout ) {
// True
if ( WC()->cart ) {
// Get number of items in the cart.
$count = WC()->cart->get_cart_contents_count();
// Result
echo '<p style="color: red; font-size: 25px;">Count = ' . $count . '</p>';
}
}
add_action( 'woocommerce_before_order_notes', 'action_woocommerce_before_order_notes', 10, 1 );
Note: although the advantage here is that you can continue to use the get_cart_contents_count()
function in this way, the disadvantage is that this function would also display the modified result when used for other purposes
