如何在 smarty 模板中插入换行符？

Question

我有一个 smarty 模板代码如下，我想将 smarty 模板数据逐行写入文本文件。为此，我必须在每条记录的末尾插入一个换行符（即在值$user_test_result.test_result_data.total_obtained_marks 之后）。这应该如何实现？请帮我解决这个问题。提前致谢。

{if $all_user_test_result}{assign var='sr_no' value=1}{foreach from=$all_user_test_result item=user_test_result key=key}{if $key!='sort_user_name' && $key!='sort_total_obtained_marks' && $key!='sort_no_correct_answers' && $key!='sort_no_wrong_answers' && $key!='sort_no_skipped_questions'}{$sr_no};{if $user_test_result.test_user_data.user_status=='Attempted'}{$user_test_result.test_user_data.user_name};{else}{$user_test_result.test_user_data.user_name};{/if}{if $user_test_result.test_user_data.user_status=='Attempted'}{$user_test_result.test_user_data.test_user_time_used};{else}--{/if}{if $user_test_result.test_user_data.user_status=='Attempted'}{$user_test_result.test_result_data.no_correct_answers};{else}-{/if}{if $user_test_result.test_user_data.user_status=='Attempted'}{$user_test_result.test_result_data.no_wrong_answers};{else}-{/if}{if $user_test_result.test_user_data.user_status=='Attempted'}{$user_test_result.test_result_data.no_skipped_questions};{else}-{/if}{if $user_test_result.test_user_data.user_status=='Attempted'}{$user_test_result.test_result_data.total_obtained_marks};{else}-{/if}{/if}{assign var='sr_no' value=$sr_no+1}{/foreach}{else}Result not found{/if} 

Answer 1

在值$user_test_result.test_result_data.total_obtained_marks 之后应该有一个换行符（“\n”），并在其周围放置智能标记，如{“\n”}。你会得到想要的结果。

Answer 2

除非我弄错了，否则 Smarty 会将模板中的所有空格直接输出到文件中。因此，与其将所有 smarty 标签放在一行上，不如在适当的位置插入换行符。

{if $all_user_test_result}{assign var='sr_no' value=1}{foreach from=$all_user_test_result item=user_test_result key=key}{if $key!='sort_user_name' && $key!='sort_total_obtained_marks' && $key!='sort_no_correct_answers' && $key!='sort_no_wrong_answers' && $key!='sort_no_skipped_questions'}{$sr_no};{if $user_test_result.test_user_data.user_status=='Attempted'}{$user_test_result.test_user_data.user_name};{else}{$user_test_result.test_user_data.user_name};{/if}{if $user_test_result.test_user_data.user_status=='Attempted'}{$user_test_result.test_user_data.test_user_time_used};{else}--{/if}{if $user_test_result.test_user_data.user_status=='Attempted'}{$user_test_result.test_result_data.no_correct_answers};{else}-{/if}{if $user_test_result.test_user_data.user_status=='Attempted'}{$user_test_result.test_result_data.no_wrong_answers};{else}-{/if}{if $user_test_result.test_user_data.user_status=='Attempted'}{$user_test_result.test_result_data.no_skipped_questions};{else}-{/if}{if $user_test_result.test_user_data.user_status=='Attempted'}{$user_test_result.test_result_data.total_obtained_marks};{else}-{/if}
{/if}{assign var='sr_no' value=$sr_no+1}{/foreach}{else}Result not found{/if}

为了便于阅读，您还可以在模板中包含不输出的换行符，方法是将它们放入{* comments *}：

{if $all_user_test_result}{*
    *}{assign var='sr_no' value=1}{*
    *}{foreach from=$all_user_test_result item=user_test_result key=key}{*
        *}{if $key!='sort_user_name' && $key!='sort_total_obtained_marks' && $key!='sort_no_correct_answers' && $key!='sort_no_wrong_answers' && $key!='sort_no_skipped_questions'}{*
            *}{$sr_no};{if $user_test_result.test_user_data.user_status=='Attempted'}{$user_test_result.test_user_data.user_name};{else}{$user_test_result.test_user_data.user_name};{/if}{*
            *}{if $user_test_result.test_user_data.user_status=='Attempted'}{$user_test_result.test_user_data.test_user_time_used};{else}--{/if}{*
            *}{if $user_test_result.test_user_data.user_status=='Attempted'}{$user_test_result.test_result_data.no_correct_answers};{else}-{/if}{*
            *}{if $user_test_result.test_user_data.user_status=='Attempted'}{$user_test_result.test_result_data.no_wrong_answers};{else}-{/if}{*
            *}{if $user_test_result.test_user_data.user_status=='Attempted'}{$user_test_result.test_result_data.no_skipped_questions};{else}-{/if}{*
            *}{if $user_test_result.test_user_data.user_status=='Attempted'}{$user_test_result.test_result_data.total_obtained_marks};{else}-{/if}{*
        *}{* Add newline at end of record *}
        {/if}{*
        *}{assign var='sr_no' value=$sr_no+1}{*
    *}{/foreach}{*
*}{else}Result not found{*
*}{/if}
