php – Woocommerce在结帐页面上获取购物车中特定商品的数量

导读：我试图在结帐屏幕中显示自定义字段,这些字段以2件事为条件. 如果产品#1769和/或产品#1770在客户的购物车中. 当前购物车中的#1769和/或#1770的数量将决定要显示的自定义字段的数量. 现在我已经通过以下方式处理了#1： /*** Check to see what is in the cart*

* Check to see what is in the cart
*
* @param $product_id
*
* @return bool
*/
function conditional_product_in_cart( $product_id ) {
//Check to see if user has product in cart
global $woocommerce;
$check_in_cart = false;
foreach ( $woocommerce->cart->get_cart() as $cart_item_key => $values ) {
$_product = $values['data'];
if ( $_product->id === $product_id ) {
$check_in_cart = true;
}
}
return $check_in_cart;
}
function checkout_register_names( $checkout ) {
$check_in_cart = conditional_product_in_cart(1769);
// Product id 1769 is in cart so show custom fields
if ($check_in_cart === true ) {
// Display custom fields for 1769...
woocommerce_form_field( 'golf_field_one',array(
'type' => 'text','class' => array('my-field-class form-row-wide'),'label' => __('Golfer #1'),'placeholder' => __('Name'),),$checkout->get_value( 'golf_field_one' ));
woocommerce_form_field( 'golf_field_two','label' => __('Golfer #2'),$checkout->get_value( 'golf_field_two' ));
//etc...
}
$check_in_cart = conditional_product_in_cart(1770);
// Product id 1770 is in cart so show custom fields
if ($check_in_cart === true ) {
// Display custom fields for 1770...
woocommerce_form_field( 'dinner_field_one','label' => __('Dinner Name #1'),$checkout->get_value( 'dinner_field_one' ));
woocommerce_form_field( 'dinner_field_two','label' => __('Dinner Name #2'),$checkout->get_value( 'dinner_field_two' ));
//etc...
}
}
以上代码将有条件地显示我在每个产品下设置的所有woocommerce_form_field(),仅当该产品位于客户的购物车中时. 现在,我需要做的是根据购物车中每种产品#1769或#1770的数量显示一定数量的woocommerce_form_field(). 因此,如果有两(2)个产品#1769,则应显示两个字段.如果有两(2)个产品#1769和一个(1)产品#1770,则应显示三个总字段(两个用于产品#1769,一个用于产品#1770). 在任何给定客户的购物车中,每个产品最多只会添加四个,因此将每个表单字段包装在if()中并检查以下内容并不是一件大事： if([quantity of product 1769] >= 1) {
show first woocommerce_form_field()
}
if([quantity of product 1769 >= 2) {
show second woocommerce_form_field()
} //etc...
// Repeat for product 1770...
我尝试添加$qty_in_cart = $values [‘quantity’];在第一个函数conditional_product_in_cart中的foreach(),但似乎不想给我任何东西.当我检查是否(isset($qty_in_cart))时,它没有设置. 我觉得我很亲密,但是我无法弄清楚我错过了什么.任何帮助,将不胜感激. 解决方法
我正在执行同样的任务.
我在WooTickets和WooCommerce上使用的代码片段可能对您有所帮助： if (
in_array( 'woocommerce/woocommerce.php',apply_filters( 'active_plugins',get_option( 'active_plugins' ) ) ) &&
in_array( 'wootickets/wootickets.php',get_option( 'active_plugins' ) ) )
) {
/**
* Add the field to the checkout
**/
add_action('woocommerce_after_order_notes','wt_attendee_details');
function wt_attendee_details( $checkout ) {
$attendee_count = wt_count_attendees();
if($attendee_count > 0) {
echo "</div></div>"; //close the Billing Address section to create new group of fields
echo "<div id='attendee_details'><div>"; //automatically be closed from 2 Billing Address's div - </div></div>
echo '<h3>'.__('All Event Attendees and/or clients who are ordering DVDs,please add your name and email again.').'</h3>';
for($n = 1; $n <= $attendee_count; $n++ ) {
woocommerce_form_field( 'attendee_name_'.$n,array(
'type' => 'text','class' => array('form-row form-row-first'),'label' => __('Name'),'placeholder' => __('name'),'required' => true,$checkout->get_value( 'attendee_name_'.$n ));
woocommerce_form_field( 'attendee_email_'.$n,'class' => array('form-row validate-email'),'label' => __('Email'),'placeholder' => __('email'),$checkout->get_value( 'attendee_email_'.$n ));
woocommerce_form_field( 'attendee_phone_'.$n,'class' => array('form-row form-row-last'),'label' => __('Phone'),'placeholder' => __(''),$checkout->get_value( 'attendee_phone_'.$n ));
}
echo "<style type='text/css'>
#attendee_details .form-row {
float: left;
margin-right: 2%;
width: 31%;
}
#attendee_details .form-row-last {

//echo "Attendees: " . $attendee_count;
