我在我的 woocommerce 订单页面中添加了一个自定义操作,如下所示,并且我还有一个自定义订单字段“餐数”。现在我想要的是,当我批量选择订单并使用该自定义操作时,餐食数量应该减少 1。
例如,如果订单 ID 1 和 2 的餐数分别为 15 和 12,那么在使用该操作后,它应该变成 14 和 11…
我的订单页面、自定义挂钩和我创建的自定义订单字段的屏幕截图:
我的代码:
add_filter( 'bulk_actions-edit-shop_order', 'decrease_number_of_meals_by_1' );
function decrease_number_of_meals_by_1( $bulk_actions ) {
$bulk_actions['decrease_number_of_meals'] = 'Decrease Number of Meals by 1';
return $bulk_actions;
}
add_action( 'admin_action_decrease_number_of_meals', 'fire_my_hook' );
function fire_my_hook() {
if( !isset( $_REQUEST['post'] ) && !is_array( $_REQUEST['post'] ) )
return;
foreach( $_REQUEST['post'] as $order_id ) {
$order = new WC_Order( $order_id );
$no_of_meals = $order->get_post_meta( $order_id, '_wc_acof_{3}', true );
}
}
我被困在这里,不知道如何进一步做。
请指导我如何实现这一目标。
您没有使用正确的方法和钩子。此外,使用 WooCommerce 管理自定义订单字段插件时,正确的自定义字段元键应该是
_wc_acof_3
。
所以请尝试以下方法:
// Add a bulk action to Orders bulk actions dropdown
add_filter( 'bulk_actions-edit-shop_order', 'decrease_meals_orders_bulk_actions' );
function decrease_meals_orders_bulk_actions( $bulk_actions ) {
$bulk_actions['decrease_meals'] = 'Decrease Number of Meals by 1';
return $bulk_actions;
}
// Process the bulk action from selected orders
add_filter( 'handle_bulk_actions-edit-shop_order', 'decrease_meals_bulk_action_edit_shop_order', 10, 3 );
function decrease_meals_bulk_action_edit_shop_order( $redirect_to, $action, $post_ids ) {
if ( $action === 'decrease_meals' ){
$processed_ids = array(); // Initializing
foreach ( $post_ids as $post_id ) {
// Get number of meals
$nb_meal = (int) get_post_meta( $post_id, '_wc_acof_3', true );
// Save the decreased number of meals ($meals - 1)
update_post_meta( $post_id, '_wc_acof_3', $nb_meal - 1 );
$processed_ids[] = $post_id; // Adding processed order IDs to an array
}
// Adding the right query vars to the returned URL
$redirect_to = add_query_arg( array(
'decrease_meals' => '1',
'processed_count' => count( $processed_ids ),
'processed_ids' => implode( ',', $processed_ids ),
), $redirect_to );
}
return $redirect_to;
}
// Display the results notice from bulk action on orders
add_action( 'admin_notices', 'decrease_meals_bulk_action_admin_notice' );
function decrease_meals_bulk_action_admin_notice() {
global $pagenow;
if ( 'edit.php' === $pagenow && isset($_GET['post_type'])
&& 'shop_order' === $_GET['post_type'] && isset($_GET['decrease_meals']) {
$count = intval( $_REQUEST['processed_count'] );
printf( '<div class="notice notice-success fade is-dismissible"><p>' .
_n( 'Decreased meals for %s Order.',
'Decreased meals for %s Orders.',
$count,
'woocommerce'
) . '</p></div>', $count );
}
