结帐中的WooCommerce自定义字段 [英] WooCommerce Custom Field in Checkout

问题描述

我想在WooCommerce结帐页面中添加自定义字段，但要添加所选产品。

I want add Custom field in WooCommerce checkout page but for selected products.

例如，如果客户的购物车中只有产品A ，此自定义字段应显示在 WooCommerce Checkout页面

For e.g if Client have Product A in cart only than this custom field should appear in WooCommerce Checkout Page

我正在使用functions.php中的以下代码添加自定义字段：

I am using following code in functions.php to add custom field:

add_action('woocommerce_before_order_notes', 'my_delivery_checkout_field');

function my_delivery_checkout_field( $checkout ) {

echo '<div id="my_local_club"><h3>'.__('Delivery Options').'</h3>';

woocommerce_form_field( 'delivery_options', array(
'type' => 'select',
'class' => array('my-club-class form-row-wide'),
'label' => _('<br><br>Please select your options', 'woocommerce'),
'required' => true,
'placeholder' => _x('Please Select An Option...', 'placeholder','woocommerce'),
'options' => array(
'option1' => 'Option 1',
'option_2' =>'Option 2',
 'option_3' =>'Option 3'
)
), $checkout->get_value( 'delivery_options' ));

echo '</div>';

}

// Check if Gift card is in the cart

function conditional_product_in_cart( $product_id ) {
 //Check to see if user has product in cart
 global $woocommerce;

 //flag no book in cart
 $book_in_cart = false;

 foreach ( $woocommerce->cart->get_cart() as $cart_item_key => $values ) {
 $_product = $values['data'];

 if ( $_product->id === $product_id ) {
 //book is in cart!
 $book_in_cart = true;

 }
 }

 return $book_in_cart;

}
