基于用户在Woocommerce中购买的总金额的自定义购物车通知 [英] Custom cart notice based on user total purchased amount in Woocommerce

问题描述

我正在尝试根据以下答案代码，根据用户在Woocommerce中购买的总金额显示自定义购物车通知:

I am trying to display a custom cart notice based on user total purchased amount in Woocommerce, based on this answer code:

添加Woocommerce中基于客户购买总金额的百分比折扣

它没有我想要的.

例如，如果客户下了2个订单:

For example if a customer has made 2 orders:

• 第一笔订单是200
• 二阶是122

所以总和为200 + 122 =322.但是我总共得到200. 我在做什么错了?

So the total sum is 200 + 122 = 322. But I get a total of 200. What I am doing wrong?

这是我使用的代码:

 add_action( 'woocommerce_before_cart', 'vc' );

  function vc( ) {
// Only for logged in user
if ( ( is_admin() && ! defined( 'DOING_AJAX' ) ) || ! is_user_logged_in() )
    return;
$um = WC()->session->get( 'um' );
// If not get it and save it
if( empty($um) ){
    // ==> HERE goes the function to get customer's purchases total sum
    $um = get_customer_total_purchases_sum();
    // Save it in WC_Session
    WC()->session->set('um', $um);
}
 $vv=10000 - $um;
    if ( $um > 0 && $vv >0) {

    echo '<div class="woocommerce-message"><a href="' . get_permalink( 
       woocommerce_get_page_id( 'shop' ) ) . '" class="button wc-forward">Tiếp tục mua sắm</a>Bạn cần thêm ' . wc_price($vv) . ' để được.... </div>';
}
else { 
echo '......';
  }}

感谢您的帮助.

推荐答案

尝试以下方法代替(我重新考虑了get_customer_total_purchases_sum()函数的功能):

Try the following instead (I have revisited a bit get_customer_total_purchases_sum() function):

// Utililty function to get customer's total purchases sum
function get_customer_total_purchases_sum() {
    $current_user_id = get_current_user_id(); // Current user ID

    if( $current_user_id == 0 ) return 0; // we return zero if customer is not logged in

    global $wpdb;

    // return the SQL query (paid orders sum)
    return $wpdb->get_var("SELECT SUM(pm.meta_value) FROM {$wpdb->prefix}postmeta as pm
    INNER JOIN {$wpdb->prefix}postmeta as pm2 ON pm.post_id = pm2.post_id
    INNER JOIN {$wpdb->prefix}posts as p ON pm.post_id = p.ID
    WHERE p.post_status LIKE 'wc-completed' AND p.post_type LIKE 'shop_order'
    AND pm.meta_key LIKE '_order_total' AND pm2.meta_key LIKE '_customer_user'
    AND pm2.meta_value LIKE '$current_user_id'");
}

// Display a custom notice
add_action( 'template_redirect', 'total_purchase_custom_notification' );
function total_purchase_custom_notification( ) {

    if ( is_wc_endpoint_url('order-received') && WC()->session->get( 'purchases_sum' ) ) {
        // We remove this session variable in thankyou page (if it still exist)
        WC()->session->__unset( 'purchases_sum' );
    }
    // On cart page we display a custom notice
    elseif( is_cart() ) {
        // Get customer's purchases total sum and set it in WC_Session
        if( ! WC()->session->get( 'purchases_sum' ) ){
            WC()->session->set('purchases_sum', get_customer_total_purchases_sum());
        }

        $total_purchases  = WC()->session->get( 'purchases_sum' );

        if ( $total_purchases == 0 ) return; // We exit (no purchases or non logged users)

        if ( ( 10000 - $total_purchases ) > 0 )
        {
            wc_add_notice( sprintf(
                '<a class="button alt wc-forward" style="float:right" href="%s">%s</a> ' .
                __( "You need an extra %s at all to get a...", "woocommerce" ),
                get_permalink( wc_get_page_id( 'shop' ) ),
                __( "Continue shopping", "woocommerce" ),
                strip_tags( wc_price( 10000 - $total_purchases ) )
            ), 'notice');
        }
        else
        {
            wc_add_notice( __( "......", "woocommerce"), 'notice' );
        }
    }
}

此代码位于您的活动子主题(或主题)的function.php文件中.经过测试，可以正常工作.

This code goes on function.php file of your active child theme (or theme). Tested and works.
