是否有一种方法可以根据一定数量生成许多WooCommerce优惠券

Question

我正在修复插件负载的WooCommerce网站，现在我需要根据购买金额来实现自动优惠券生成器：例如，我想建立一个规则每100美元购买，如果客户购买$ 450，则会产生4个折扣优惠券。所有这些代码都应发送给客户。

我已经查看了WooCommerce文档，可以在其中创建优惠券：https：//docs.woocommerce.com/document/create-a-coupon-programathy//已确认付款(：

function add_order_email_instructions( $order, $sent_to_admin ) {
    if ( ! $sent_to_admin && $order->get_user_id() && 'processing' == $order->get_status()) {
        $lista_cupones  = array();
        $amount = '40';
        for ($i=1; $i<=$order->get_total()/100; $i++) {
            $longitud = 12;
            $key = '';
            $pattern = '1234567890ABCDFGHIJKLMNOPQRSTUWYZ';
            $max = strlen($pattern)-1;
            for($i=0;$i < $longitud;$i++) $key .= $pattern{mt_rand(0,$max)};
            $coupon_code = $key;
            $discount_type = 'fixed_cart'; 
            $coupon = array(
                'post_title' => $coupon_code,
                'post_content' => ''.$to,
                'post_status' => 'publish',
                'post_author' => 1,
                'post_type'     => 'shop_coupon'
            );
            $new_coupon_id = wp_insert_post( $coupon );
            update_post_meta( $new_coupon_id, 'discount_type', $discount_type );
            update_post_meta( $new_coupon_id, 'coupon_amount', $amount );
            update_post_meta( $new_coupon_id, 'individual_use', 'yes' );
            update_post_meta( $new_coupon_id, 'product_ids', '' );
            update_post_meta( $new_coupon_id, 'exclude_product_ids', '' );
            update_post_meta( $new_coupon_id, 'minimum_amount', '100' );
            update_post_meta( $new_coupon_id, 'exclude_sale_items', 'yes' );
            update_post_meta( $new_coupon_id, 'exclude_sale', 'yes' );
            update_post_meta( $new_coupon_id, 'usage_limit', '1' );
            update_post_meta( $new_coupon_id, 'expiry_date', strtotime("+3 days") );
            update_post_meta( $new_coupon_id, 'apply_before_tax', 'yes' );
            update_post_meta( $new_coupon_id, 'free_shipping', 'no' );
            array_push($lista_cupones, $coupon_code);
        }
        echo '<h2>';
        printf( __( 'Obt&eacute;n 40 soles de descuento')
        );
        echo '</h2>';
        printf(
            __( 'Gracias por su compra. Use el código de descuento <strong>%2$s</strong> para recibir %1$s soles de descuento en su siguiente compra.'),
            $amount,
            $coupon_code
        );
        echo '</p>';
    }
}
add_action('woocommerce_email_before_order_table','add_order_email_instructions',10);

现在这一半有效：它验证了订单总数小于100美元并且不会产生优惠券，但是如果订单较高，它也只会给我一张优惠券，即使订单总计为200、300 400等(它不是't甚至产生了多个优惠券，似乎只能通过一次循环并停止(。

谢谢！

已经解决了，这是代码：

function create_coupon () {
    $amount = '40';
    $longitud = 12;
    $key = '';
    $pattern = '1234567890ABCDFGHIJKLMNOPQRSTUWYZ';
    $max = strlen($pattern)-1;
    for($i=0;$i < $longitud;$i++) $key .= $pattern{mt_rand(0,$max)};
    $coupon_code = $key;
    $discount_type = 'fixed_cart'; 
    $coupon = array(
        'post_title' => $coupon_code,
        'post_content' => ''.$to,
        'post_status' => 'publish',
        'post_author' => 1,
        'post_type'     => 'shop_coupon'
    );
    $new_coupon_id = wp_insert_post( $coupon );
    update_post_meta( $new_coupon_id, 'discount_type', $discount_type );
    update_post_meta( $new_coupon_id, 'coupon_amount', $amount );
    update_post_meta( $new_coupon_id, 'individual_use', 'yes' );
    update_post_meta( $new_coupon_id, 'product_ids', '' );
    update_post_meta( $new_coupon_id, 'exclude_product_ids', '' );
    update_post_meta( $new_coupon_id, 'minimum_amount', '100' );
    update_post_meta( $new_coupon_id, 'exclude_sale_items', 'yes' );
    update_post_meta( $new_coupon_id, 'exclude_sale', 'yes' );
    update_post_meta( $new_coupon_id, 'usage_limit', '1' );
    update_post_meta( $new_coupon_id, 'expiry_date', strtotime("+3 days") );
    update_post_meta( $new_coupon_id, 'apply_before_tax', 'yes' );
    update_post_meta( $new_coupon_id, 'free_shipping', 'no' );
    //update_post_meta( $new_coupon_id, 'customer_email', $order->get_billing_email());
    return $coupon_code;
}
function add_order_email_instructions( $order, $sent_to_admin ) {
        if ( ! $sent_to_admin && $order->get_user_id() && 'processing' == $order->get_status()) {
            $lista_cupones  = [];
            $numero_cupones = $order->get_total()/100;
            for ($i=1; $i<=$numero_cupones; $i++) { 
                array_push($lista_cupones, create_coupon());
            }
            echo '<h2>';
            printf( __( 'Obt&eacute;n 40 soles de descuento')
            );
            echo '</h2>';
            printf(
                __( 'Gracias por su compra. Use el código de descuento <strong>%2$s</strong> para recibir %1$s soles de descuento en su siguiente compra.'),
                $amount,
                $lista_cupones 
            );
            echo '<br></p>';
        }
}
add_action('woocommerce_email_before_order_table','add_order_email_instructions',10);

这是未完成的，现在我必须在邮件中以足够的数组格式显示
