php - 交易后如何在会员新闻感谢页面上添加 GA 跟踪

Question

我想知道如何在会员新闻“谢谢”页面上添加谷歌跟踪，基本上是在用户支付每月或定期付款之后，然后它将数据发送到谷歌分析，并带有“他们购买的计划的名称” 、“支付金额”和“交易id”。

我得到了这段代码，但它没有触发任何东西，或者这不是正确的代码？我不知道如何调试MemberPress所以我遇到了问题，请任何人帮助...

function echo_mepr_tracking_script() {

  if(isset($_GET['membership']) && isset($_GET['trans_num'])) {
    $txn = MeprTransaction::get_one_by_trans_num($_GET['trans_num']);
    
    
    if(isset($txn->id) && $txn->id > 0) {
      $trans_id = $txn->id;
      $total = $txn->total;

      // Update total if recurring
      if($txn->subscription_id > 0) {
        $sub = new MeprSubscription($txn->subscription_id);

        if(isset($sub->id) && $sub->id > 0) {
          $trans_id = $sub->id; // Use subscription ID as the payment id for recurring subscriptions

          //Trial period?
          if($sub->trial) {
            $total = $sub->trial_amount;
          } else {
            $total = $sub->total;
            
          }
          
        }
        
      }

      ?>
        <script>
          var fh5coMeprTxnNum = '<?php echo urlencode($trans_id); ?>';
          var fh5coMeprTxnAmount = '<?php echo floatval($total); ?>';
          fbq('track', 'Purchase', {currency: "USD", value: fh5coMeprTxnAmount});
          ga('require', 'ecommerce');
          ga('ecommerce:addTransaction', {
            'id': fh5coMeprTxnNum,
            'revenue': fh5coMeprTxnAmount
          });
          ga('ecommerce:send');
          alert('yes');
        </script>
      <?php
    }
  }
}
add_action('wp_footer', 'echo_mepr_tracking_script');

Google 需要为它的电子商务跟踪传递一些额外的变量。

我最近在许多 MemberPress 感谢页面上实现了这一点，基于此 gist中的代码，但使用MemberPress Shortcodes。

如果您更喜欢通过 Wordpress 操作挂钩来实现，那么请确保包含 Google Analytics 定义的所有必需变量：

addTransaction: id, total
addItem: 名称, sku, 价格, 数量

<script>
    var txnId = '[mepr-ecommerce-tracking]%%txn_id%%[/mepr-ecommerce-tracking]';
    // Check for a valid transaction ID before firing...
    if ( txnId ) { 
        ga('require', 'ecommerce');
        ga('ecommerce:addTransaction', {
            id: '[mepr-ecommerce-tracking]%%txn_id%%[/mepr-ecommerce-tracking]' // Transaction ID,
            affiliation: 'Your Store', // Affiliation or store name
            revenue: '[mepr-ecommerce-tracking]%%total%%[/mepr-ecommerce-tracking]', // Grand Total
            shipping: 0, // Shipping cost (n/a for MemberPress)
            tax: '[mepr-ecommerce-tracking]%%tax_amount%%[/mepr-ecommerce-tracking]' // Tax
        });
        ga('ecommerce:addItem', { 
            id: '[mepr-ecommerce-tracking]%%txn_id%%[/mepr-ecommerce-tracking]', // Transaction ID 
            sku: '[mepr-ecommerce-tracking]%%membership_id%%[/mepr-ecommerce-tracking]', // Subscription ID
            name: '[mepr-ecommerce-tracking]%%membership_name%%[/mepr-ecommerce-tracking]', // Membership Name
            category: '', // Category (n/a for MemberPress)
            price: '[mepr-ecommerce-tracking]%%total%%[/mepr-ecommerce-tracking]', // Unit price
            quantity: 1
        });
        ga('ecommerce:send');
    } 
</script>
