Php WooCommerce产品级简单票务系统
我正在使用WordPress和WooCommerce,并且有一个SQL查询来调用特定产品类型的元标记Php WooCommerce产品级简单票务系统,php,mysql,wordpress,woocommerce,orders,Php,Mysql,Wordpress,Woocommerce,Orders,我正在使用WordPress和WooCommerce,并且有一个SQL查询来调用特定产品类型的元标记 function get_last_order_id_from_product( $product_id ) { global $wpdb; return $wpdb->get_col( $wpdb->prepare( " SELECT oi.order_id FROM {$wpdb->prefix}woocommerce_order_items as oi

上面的代码获取产品id并输出meta标记,当我意识到当用户购买超过一个数量时,它为“Ticket Number”键创建的meta值是“10 11”,mysql将其视为单个字符串时,我的问题就出现了。我尝试使用如上所示的SUBSTRING_索引将其拆分,但它不会查看超过第一个索引的任何订单
我需要它将数字视为单个数字,这样,如果用户购买了10个项目,它可以识别最后一个数字为最高数字(例如21 22 23 24),下一个购买此产品的用户,sql查询将识别字符串中的24为最高数字,并使新项目元为25
这是我的函数,如果它有任何用途,它当前运行,但仅从元值1开始工作,无论购买了多少产品:
add_action('woocommerce_order_status_processing', 'action_woocommerce_order_status_completed');
function action_woocommerce_order_status_completed($order_id) {
$order = new WC_Order($order_id);
$items = $order->get_items();
foreach ($items as $key => $value) {
$get_last_order = get_last_order_id_from_product( 10 );
if ($get_last_order == null){
$gen_id_1 = "0";
} else {
$get_order_id = implode($get_last_order);
$lastorder = wc_get_order($get_order_id);
$lastitem = $lastorder->get_items();
foreach ($lastitem as $key2 => $value2) {
$custom_thing = $value2->get_meta('Ticket Number');
}
$gen_ids = explode(' ', $custom_thing);
$gen_id_1 = end($gen_ids);
}
$qua = $value->get_quantity();
for ($x = 1; $x <= $qua; $x++) {
$gen_id_1++;
$gen_id_2 .= " $gen_id_1";
};
$value->add_meta_data( "Ticket Number", $gen_id_2);
$value->save();
}
}
add_action('woocommerce_order_status_processing'、'action_woocommerce_order_status_completed');
功能操作\商业\订单\状态\完成($order\ id){
$order=新WC\U订单($order\U id);
$items=$order->get_items();
foreach($key=>$value的项目){
$get_last_order=从产品(10)获取_last_order_id_;
if($get\u last\u order==null){
$gen_id_1=“0”;
}否则{
$get\u order\u id=内爆($get\u last\u order);
$lastorder=wc\U get\U order($get\U order\U id);
$lastitem=$lastorder->get_items();
foreach($key2=>$value2的最后一项){
$custom_thing=$value2->get_meta(“票号”);
}
$gen_id=爆炸(“”,$custom_thing);
$gen_id_1=结束($gen_id);
}
$qua=$value->get_quantity();
对于($x=1;$x添加元数据(“票号,$gen\u id\u 2”);
$value->save();
}
}
有一种不同的方法,更容易、更有效地实现这一点
订单更改为处理状态时:
- 首先,对于每个订单项目,我增加销售的票证数量(项目数量),作为产品级别的索引(保存/更新为自定义产品元数据)
- 然后,对于每个订单项目,我根据项目数量从相关产品索引(更新之前)生成票据编号,并将其保存为自定义订单项目元数据
- 最后,对于每个订单项目,我更新相关的产品“索引”,将销售数量添加到当前的“索引”值
代码放在活动子主题(活动主题)的functions.php文件中。它应该可以工作。这太完美了,非常感谢。我不知道你真的可以这样做,这是我第一次使用woocommerce进行开发,所以我仍在摸索。
