Question

在我的视图文件中，我正在生成一个表格，如下所示

<?php
foreach ($accounts as $row) {
  echo '<tr>';
  echo '<td>' . $row['id'] . '</td>';
  echo '<td>' . $row['total_online_sale'] . '</td>';
  echo '<td>' . $row['product_price'] . '</td>';
  echo '<td>' . $row['discount'] . '</td>';
}
?>

我想生成<tfoot>标记所包围的行中这些列的总和值。我不想在模特中做这个操作。我应该怎么做？

Answer 1

您可以这样做，在循环中汇总值，然后在<tfoot>标记

中循环打印这些值

<?php
$total_online_sale= 0;
$product_price=0;
$discount =0;
foreach ($accounts as $row) {
$total_online_sale += $row['total_online_sale'];
$product_price +=$row['product_price'];
$discount +=$row['discount'];
  echo '<tr>';
  echo '<td>' . $row['id'] . '</td>';
  echo '<td>' . $row['total_online_sale'] . '</td>';
  echo '<td>' . $row['product_price'] . '</td>';
  echo '<td>' . $row['discount'] . '</td>';
  echo '</tr>';
}
echo '<tfoot>';
  echo '<tr>';
  echo '<td>&nbsp;</td>';
  echo '<td>' . $total_online_sale . '</td>'; //Grand sum for column total_online_sale 
  echo '<td>' . $product_price . '</td>'; //Grand sum for column product_price 
  echo '<td>' . $discount. '</td>'; //Grand sum for column discount
  echo '</tr>';
echo '</tfoot>';

?>
