我在我的WooCommerce單一產品上有自定義字段。它發送到購物車罰款,它顯示在結帳罰款,它顯示在儀表板罰款。將自定義字段數據添加到WooCommerce訂單
我現在試圖做的是將該值設置爲訂單頁面中的自定義字段,以便我可以在需要時修改文本。出於某種原因,當我提交表單時,此步驟不起作用。
,我在我的functions.php
文件中使用的代碼:
// Add the field to the product
add_action('woocommerce_before_add_to_cart_button', 'my_custom_checkout_field');
function my_custom_checkout_field() {
echo '<div id="my_custom_checkout_field"><h3>'.__('My Field').'</h3>';
echo '<label>fill in this field</label> <input type="text" name="my_field_name">';
echo '</div>';
}
// Store custom field
function save_my_custom_checkout_field($cart_item_data, $product_id) {
if(isset($_REQUEST['my_field_name'])) {
$cart_item_data[ 'my_field_name' ] = $_REQUEST['my_field_name'];
/* below statement make sure every add to cart action as unique line item */
$cart_item_data['unique_key'] = md5(microtime().rand());
}
return $cart_item_data;
}
add_action('woocommerce_add_cart_item_data', 'save_my_custom_checkout_field', 10, 2);
// Render meta on cart and checkout
function render_meta_on_cart_and_checkout($cart_data, $cart_item = null) {
$custom_items = array();
/* Woo 2.4.2 updates */
if(!empty($cart_data)) {
$custom_items = $cart_data;
}
if(isset($cart_item['my_field_name'])) {
$custom_items[] = array("name" => 'My Field', "value" => $cart_item['my_field_name']);
}
return $custom_items;
}
add_filter('woocommerce_get_item_data', 'render_meta_on_cart_and_checkout', 10, 2);
// Display as order meta
function my_field_order_meta_handler($item_id, $values, $cart_item_key) {
if(isset($values['my_field_name'])) {
wc_add_order_item_meta($item_id, "my_field_name", $values['my_field_name']);
}
}
add_action('woocommerce_add_order_item_meta', 'my_field_order_meta_handler', 1, 3);
/** THIS IS WHERE I'M STUCK **/
add_action('woocommerce_checkout_process', 'my_custom_checkout_field_process');
function my_custom_checkout_field_process() {
global $woocommerce;
// Check if set, if its not set add an error. This one is only requite for companies
if ($_POST['billing_company'])
if (!$_POST['my_field_name'])
$woocommerce->add_error(__('Please enter your XXX.'));
}
// Update the user meta with field value
add_action('woocommerce_checkout_update_user_meta', 'my_custom_checkout_field_update_user_meta');
function my_custom_checkout_field_update_user_meta($user_id) {
if ($user_id && $_POST['my_field_name']) update_user_meta($user_id, 'my_field_name', esc_attr($_POST['my_field_name']));
}
// Update the order meta with field value
add_action('woocommerce_checkout_update_order_meta', 'my_custom_checkout_field_update_order_meta');
function my_custom_checkout_field_update_order_meta($order_id) {
if ($_POST['my_field_name']) update_post_meta($order_id, 'My Field', esc_attr($_POST['my_field_name']));
}

我想什麼情況發生:
任何幫助將不勝感激。
謝謝你,這肯定把我在正確的軌道,我掙扎的最後一件事上是結帳處理階段。由於我的字段實際上已插入產品頁面,因此如何處理與此字段的結帳,而不必將其作爲文檔中所示的必填字段? –
