UPDATE 2017/11/02(在Woocommerce完美作品3+)
首先我得到的一切工作已经预期,除了在后端所获得的价值为my_field_name
订单页面中的“自定义字段”Metabox。
然后,一个真正的噩梦后,我有发现一个相当不错的工作解决方案,比以前更好。在后端,你现在有显示正确的价值,就像这个截图自定义字段my_field_name
自定义metabox:
我的代码被分成两个部分。
1)后端Metabox为了页面,以示出从产品上的网页的自定义字段来正确的值的可编辑字段(前端):
// Adding Meta container admin shop_order pages
add_action('add_meta_boxes', 'mv_add_meta_boxes');
if (! function_exists('mv_add_meta_boxes'))
{
function mv_add_meta_boxes()
{
add_meta_box('mv_other_fields', __('My Field','woocommerce'), 'mv_add_other_fields_for_packaging', 'shop_order', 'side', 'core');
}
}
// Adding Meta field in the meta container admin shop_order pages
if (! function_exists('mv_add_other_fields_for_packaging'))
{
function mv_add_other_fields_for_packaging()
{
global $post;
$meta_field_data = get_post_meta($post->ID, '_my_field_slug', true) ? get_post_meta($post->ID, '_my_field_slug', true) : '';
echo '<input type="hidden" name="mv_other_meta_field_nonce" value="' . wp_create_nonce() . '">
<p style="border-bottom:solid 1px #eee;padding-bottom:13px;">
<input type="text" style="width:250px;";" name="my_field_name" placeholder="' . $meta_field_data . '" value="' . $meta_field_data . '"></p>';
}
}
// Save the data of the Meta field
add_action('save_post', 'mv_save_wc_order_other_fields', 10, 1);
if (! function_exists('mv_save_wc_order_other_fields'))
{
function mv_save_wc_order_other_fields($post_id) {
// We need to verify this with the proper authorization (security stuff).
// Check if our nonce is set.
if (! isset($_POST[ 'mv_other_meta_field_nonce' ])) {
return $post_id;
}
$nonce = $_REQUEST[ 'mv_other_meta_field_nonce' ];
//Verify that the nonce is valid.
if (! wp_verify_nonce($nonce)) {
return $post_id;
}
// If this is an autosave, our form has not been submitted, so we don't want to do anything.
if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE) {
return $post_id;
}
// Check the user's permissions.
if ('page' == $_POST[ 'post_type' ]) {
if (! current_user_can('edit_page', $post_id)) {
return $post_id;
}
} else {
if (! current_user_can('edit_post', $post_id)) {
return $post_id;
}
}
// --- Its safe for us to save the data ! --- //
// Sanitize user input and update the meta field in the database.
update_post_meta($post_id, '_my_field_slug', $_POST[ 'my_field_name' ]);
}
}
2)前端/后端:
•产品页面自定义字段(前端)。
•在购物车上显示此数据,结帐页面和感谢订单(前端)。
•显示订单页面上的数据(后端)
// Add the field to the product
add_action('woocommerce_before_add_to_cart_button', 'my_custom_product_field');
function my_custom_product_field() {
echo '<div id="my_custom_field">
<label>' . __('My Field') . ' </label>
<input type="text" name="my_field_name" value="">
</div><br>';
}
// Store custom field
add_action('woocommerce_add_cart_item_data', 'save_my_custom_product_field', 10, 2);
function save_my_custom_product_field($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());
WC()->session->set('my_order_data', $_REQUEST['my_field_name']);
}
return $cart_item_data;
}
// Add a hidden field with the correct value to the checkout
add_action('woocommerce_after_order_notes', 'my_custom_checkout_field');
function my_custom_checkout_field($checkout) {
$value = WC()->session->get('my_order_data');
echo '<div id="my_custom_checkout_field">
<input type="hidden" class="input-hidden" name="my_field_name" id="my_field_name" value="' . $value . '">
</div>';
}
// Save the order meta with hidden field value
add_action('woocommerce_checkout_update_order_meta', 'my_custom_checkout_field_update_order_meta');
function my_custom_checkout_field_update_order_meta($order_id) {
if (! empty($_POST['my_field_name'])) {
update_post_meta($order_id, '_my_field_slug', $_POST['my_field_name']);
}
}
// Display field value on the order edit page (not in custom fields metabox)
add_action('woocommerce_admin_order_data_after_billing_address', 'my_custom_checkout_field_display_admin_order_meta', 10, 1);
function my_custom_checkout_field_display_admin_order_meta($order){
$my_custom_field = get_post_meta($order->id, '_my_field_slug', true);
if (! empty($my_custom_field)) {
echo '<p><strong>'. __("My Field", "woocommerce").':</strong> ' . get_post_meta($order->id, '_my_field_slug', true) . '</p>';
}
}
// Render meta on cart and checkout
add_filter('woocommerce_get_item_data', 'render_meta_on_cart_and_checkout', 10, 2);
function render_meta_on_cart_and_checkout($cart_data, $cart_item = null) {
$custom_items = array();
if(!empty($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 $custom_items;
}
// Add the information as meta data so that it can be seen as part of the order
add_action('woocommerce_add_order_item_meta','add_values_to_order_item_meta', 10, 3);
function add_values_to_order_item_meta($item_id, $cart_item, $cart_item_key) {
// lets add the meta data to the order (with a label as key slug)
if(! empty($cart_item['my_field_name']))
wc_add_order_item_meta($item_id, __('My field label name'), $cart_item['my_field_name'], true);
}
一切工作为目前预计。
自定义字段将有一个DVD列表,所以输出将如下所示:DVD 1,DVD 2.我需要能够删除已发送的DVD,因此我不会将它们发送两次。 –
