Php 将订单总数量另存为Shipstation的自定义字段
我一直在编写一个WP插件,用于计算订单的平方英寸总体积,并通过自定义字段将其发送到Shipstation:Php 将订单总数量另存为Shipstation的自定义字段,php,wordpress,woocommerce,plugins,orders,Php,Wordpress,Woocommerce,Plugins,Orders,我一直在编写一个WP插件,用于计算订单的平方英寸总体积,并通过自定义字段将其发送到Shipstation: <?php global $woocommerce; $items = $woocommerce->cart->get_cart(); //Debugging function function console_log( $data ){ echo '<script>'; echo 'console.log('. j

我通过SFTP将其上传到站点文件,并在WP上显示,但当我单击“激活”时,我收到一个致命错误:
致命错误:未捕获错误:在/nas/content/live/sfmstaging/wp content/plugins/boxCalc/boxCalc.php中调用null上的成员函数get_cart():10堆栈跟踪:#0/nas/content/live/sfmstaging/wp admin/includes/plugin.php(2299):include(){main}在第10行的/nas/content/live/sfmstaging/wp content/plugins/boxCalc/boxCalc.php中抛出
我是否将购物车数据拉对了?Woocommerce global是否存在问题?请注意,购物车是实时客户对象,您无法在实际操作中获取 现在在
woocommerce\u shipstation\u export\u custom\u字段中,过滤器钩子只是返回现有订单自定义字段的元键
这意味着当客户下订单时,您需要将购物车总容量保存为自定义订单元数据
请尝试以下操作:
// Custom function to get the volume of a product
function get_product_volume( $product ) {
return $product->get_length() * $product->get_width() * $product->get_height();
}
// Save the cart total volume as custom order meta data
add_action('woocommerce_checkout_create_order', 'save_order_total_volume');
function save_order_total_volume( $order ) {
$total_volume = 0; // Initializing
// Loop through order items
foreach( $order->get_items() as $item ){
$item_volume = get_product_volume($item->get_product()) * $item->get_quantity();
// For product variations (if volume is not accessible get the volume of the parent variabl product)
if( ! $item_volume ) {
$total_volume += get_product_volume( wc_get_product( $item->get_product_id() ) ) * $item->get_quantity();
} else {
$total_volume += $item_volume;
}
}
$order->update_meta_data( '_total_volume', $total_volume ); // Save total volume as custom order meta data
}
// Add total volume custom field meta key for export to ship station
add_filter( 'woocommerce_shipstation_export_custom_field_2', 'shipstation_custom_field_2' );
function shipstation_custom_field_2( $custom_field_key ) {
return '_total_volume';
}
代码放在活动子主题(或活动主题)的functions.php文件或插件文件中。已测试并运行。是否可以将其作为插件?
