本文介绍了在 Woocommerce 的管理订单列表上处理自定义批量操作的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着跟版网的小编来一起学习吧!

问题描述

我在我的 woocommerce 订单页面中添加了一个自定义操作,如下所示,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,用餐次数应减少 1.
例如,如果订单 ID 1 &2 有 15 &分别是 12 餐,然后在使用该动作后应变为 14 &11…

I have added a custom action in my woocommerce orders page like shown below, and I also have a custom order field "number of meals". Now what I want is when I select the orders in bulk and use that custom action then count of number of meals should get decreased by 1.
For example if order id 1 & 2 had 15 & 12 number of meals respectively then after using the action it should become 14 & 11…

我的订单页面截图,我创建的自定义钩子和自定义订单字段:

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.

I am stuck here and have no idea on how to do it further.
Please guide me on how can I achieve this.

推荐答案

您没有使用正确的方法和钩子.当使用 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.

You are not using the right way and hooks. Also the right custom field meta key should be _wc_acof_3 when using WooCommerce Admin Custom Order Fields plugin.

因此请尝试以下操作:

// 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 );
    }

代码位于活动子主题(或活动主题)的 function.php 文件中.经测试有效.

Code goes in function.php file of your active child theme (or active theme). Tested and works.
