WooCommerce自定義字段在結帳

Question

我想在WooCommerce結帳頁面添加自定義字段，但對於選定的產品。

對於例如，如果客戶有產品A在車只比這個自定義字段應該頁出現在WooCommerce結帳

我使用下面的代碼functions.php中添加自定義字段：

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>'; 

}

Answer 2

所以下面的代碼解決了我問題歸功於StackOverFlow.com

/** 
* Add the field to the checkout 
**/ 
add_action('woocommerce_before_order_notes', 'my_delivery_checkout_field'); 

function my_delivery_checkout_field($checkout) { 

    //Check if gift card is in cart 
    $book_in_cart = conditional_product_in_cart(7267); 

if ($book_in_cart === true) { 
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; 

}
