如何在 smarty foreach 循环中排除最后一个数组元素的执行？

Question

下面是一个名为 $user_transactions 的数组，它被分配给 smarty 模板：

            [failed_transaction_count] => 0
        )

)

在我的 smarty 模板中打印我在 forach 循环之后使用的数组元素：

<tbody>
  {if $user_transactions}           
    {foreach from=$user_transactions item='my_transaction'}
      <tr>
        <td>
          <div class="checkbxd"><input class="custom-check" type="checkbox" name="subject" id="subject"></div><div class="checkbxd_txt">{$my_transaction.transaction_no}</div>
        </td>
        <td>{$my_transaction.transaction_date}</td>
        <td>{$my_transaction.transaction_status|capitalize:true}</td>
        <td>{$my_transaction.transaction_total_amount}</td>
        <td align="left">
          <a href="{$control_url}modules/transactions/view_transactions.php?op=payment_details&page={$cur_page}&txn_no={$my_transaction.transaction_no}&user_id={$my_transaction.transaction_user_id}&from_date={$from_date}&to_date={$to_date}{if $transaction_status!=''}&transaction_status={$transaction_status}{/if}{if $transaction_no!=''}&transaction_no={$transaction_no}{/if}#searchPopContent" class="c-icn c-search inline_view_transaction_details">search</a>
        </td>
      </tr>
    {/foreach}  
  {else}
      <tr><td colspan="5" align="center"><b>You haven't made any transaction yet.</b></td></tr>
  {/if}  
  </tbody>

现在我不想访问具有键 transaction_count_data 的数组中的最后一个元素，因为它具有与其他数组元素不同的元素集。您能帮我从 smarty 循环中的 foreach 循环中排除最后一个元素吗？提前致谢。

Answer 1

我同意 HamZa 的观点，因为这应该在它到达模板之前完成。尽管如此，在 Smarty 中使用 foreach.last 属性是可能的。

{if not $smarty.foreach.my_transaction.last}do your stuff{/if}

Answer 2

您可以使用last 属性

{if $smarty.foreach.my_transaction.last}
