通过另一个文件调用函数

Question

查看/发票/ View.ctp

<?php

    if ( $payments == NULL ) {
        echo '<tr><td> -- No Payments Are Associated With This Invoice -- </td>
        <td></td>
        <td></td></tr>';
    }

?>

<? foreach ($payments as $payment): ?>

    <tr id="payment_row_<?= $payment['id'] ?>">
        <td class="responsive_cell"><?php echo $payment['method']?></td>
        <td class="date_cell responsive_cell"><?php echo $payment['date']?></td>
        <td class="right responsive_cell"><?php echo number_format($payment['amount'], 2, '.', ',')?></td>
    </tr>

    <?php  $paymentsTotal += $payment['amount'] ?>

<? endforeach; ?>

查看/发票/ email.ctp

$bedrag = $settings['Setting']['currency'].$thisInvoice['Payment'];

EMail.ctp和View.ctp中的这个回声的数组显示了正确的金额。

如何在Email.ctp中获得正确的金额？
