在woocommerce单页产品上,我创建了一个自定义字段。我希望在验证订单时将其值存储在订单元中。经过几个小时的研究,我还没有找到任何解决方案!但是我敢肯定我已经很接近了...
这是我的实际代码:
// create the custom field
add_action( 'woocommerce_before_add_to_cart_button', 'add_fields_before_add_to_cart', 100 );
function add_fields_before_add_to_cart($post) {
?>
<select class="selectpicker" name="premiere_box_abo" id="premiere_box_abo">
<option value="Septembre 2018">Septembre 2018</option>
<option value="Octobre 2018">Octobre 2018</option>
</select>
<?php
}
// Store custom field
function save_my_custom_checkout_field( $cart_item_data, $product_id ) {
if( isset( $_POST['premiere_box_abo'] ) ) {
$cart_item_data[ 'premiere_box_abo' ] = $_POST['premiere_box_abo'];
/* 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['premiere_box_abo'] ) ) {
$custom_items[] = array( "name" => '1e box abonnement', "value" => $cart_item['premiere_box_abo'] );
}
return $custom_items;
}
add_filter( 'woocommerce_get_item_data', 'render_meta_on_cart_and_checkout', 10, 2 );
// Display as order meta
add_action( 'woocommerce_add_order_item_meta', 'my_field_order_meta_handler', 1, 3 );
function my_field_order_meta_handler( $item_id, $values ) {
if( isset( $values['premiere_box_abo'] ) ) {
wc_add_order_item_meta( $item_id, "1e box abonnement", $values['premiere_box_abo'] );
}
}
// 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 ( ! empty( $_POST['premiere_box_abo'] ) ) {
update_post_meta( $order_id, 'premiere_box_abo', sanitize_text_field( $_POST['premiere_box_abo'] ) );
}
}
这是到目前为止我所拥有的:
那就是我想要的:
如何将该自定义字段数据另存为订单元数据,以使该值显示在“自定义字段”元框中。
感谢您的帮助。
答案 0 :(得分:0)
自woocommerce 3以来,您的代码有点过时并且有一些小错误。
还要回答您的主要问题,您正在尝试将一些“项目”数据另存为订单元数据,这并不是最好的做法,因为您可以为一个订单添加许多物品。
我在下面重新访问了您的代码:
// Display a custom select field below add to cart
add_action( 'woocommerce_before_add_to_cart_button', 'add_field_before_add_to_cart', 10 );
function add_field_before_add_to_cart() {
global $product;
?>
<select class="selectpicker" name="premiere_box_abo" id="premiere_box_abo">
<option value="Septembre 2018">Septembre 2018</option>
<option value="Septembre 2018">Octobre 2018</option>
</select>
<?php
}
// Add select field value as custom cart item data
add_filter( 'woocommerce_add_cart_item_data', 'add_cart_item_custom_data', 20, 2 );
function add_cart_item_custom_data( $cart_item_data, $product_id ) {
if( isset( $_POST['premiere_box_abo'] ) ) {
$cart_item_data['custom_data'] = $_POST['premiere_box_abo'];
$cart_item_data['unique_key'] = md5( microtime().rand() );
}
return $cart_item_data;
}
// Display custom cart item data in cart and checkout
add_filter( 'woocommerce_get_item_data', 'display_custom_cart_item_data', 20, 2 );
function display_custom_cart_item_data( $cart_item_data, $cart_item ) {
if( isset( $cart_item['custom_data'] ) ) {
$cart_item_data[] = array(
'name' => __('1e box abonnement'),
'value' => $cart_item['custom_data']
);
}
return $cart_item_data;
}
// Save / Display custom field value as custom order item meta data
add_action( 'woocommerce_checkout_create_order_line_item', 'custom_field_update_order_item_meta', 20, 4 );
function custom_field_update_order_item_meta( $item, $cart_item_key, $values, $order ) {
if( isset($values['custom_data']) ){
$item->update_meta_data( __('1e box abonnement'), $values['custom_data'] );
}
}
// Save custom fields values as custom order meta data
add_action( 'woocommerce_checkout_create_order', 'my_custom_checkout_field_update_order_meta', 20, 2 );
function my_custom_checkout_field_update_order_meta( $order, $data ) {
$premiere_box_abo = array();
// Loop through order items
foreach( $order->get_items() as $item ){
// Set each order item '1e box abonnement' in an array
$premiere_box_abo[] = $item->get_meta( __('1e box abonnement') );
}
// Save the data as a coma separated string in order meta data
if( sizeof($premiere_box_abo) > 0 )
$order->update_meta_data( 'premiere_box_abo', implode( ',', $premiere_box_abo ) );
}
代码进入您的活动子主题(或活动主题)的function.php文件中。经过测试,可以正常工作。
