html - Perl 模块 HTML::Template 可以使用 <TMPL_VAR NAME=...> 之外的其他语法吗？

Question

我正在尝试使用 Perl 模块 HTML::Template 并且根据文档，它说您可以使用 HTML评论而不是大于/小于其标记，但它对我不起作用。

来自 HTML::Template 的 perldoc

If you're a fanatic about valid HTML and would like your templates to conform to valid HTML syntax, you may optionally type template tags in the form of HTML comments. This may be of use to HTML authors who would like to validate their templates' HTML syntax prior to HTML::Template processing, or who use DTD-savvy editing tools.

   <!-- TMPL_VAR NAME=PARAM1 -->

当我尝试这样做时，我在我的 Apache 日志中收到了这些消息:

[Tue Jul 03 19:24:23 2012] [error] [client ::1] HTML::Template : Attempt to set nonexistent parameter 'fname' - this parameter name doesn't match any declarations in the template file : (die_on_bad_params => 1) at /var/www/cgi-bin/form.cgi line 90, referer: .... getcontactinfo.html

将选项 die_on_bad_params => 0 设置为 HTML::Template->new 方法似乎允许模板名称的注释格式起作用，任何人都可以确认这是完成此任务的正确方法吗？

下面是一些实际的代码:

来 self 的 .html 模板文件

<tbody>
<tr>             <td>First Name:         </td>  <td><!-- TMPL_VAR NAME=FNAME -->           </td> </tr>
<tr>             <td>Name:               </td>  <td><!-- TMPL_VAR NAME=NAME -->           </td> </tr>
<tr class="alt"> <td>Email:              </td>  <td><!-- TMPL_VAR NAME=EMAIL -->          </td> </tr>
<tr>             <td>Affiliation:        </td>  <td><!-- TMPL_VAR NAME=AFFILIATION -->    </td> </tr>

来 self 的 .cgi 脚本

my $template = HTML::Template->new(filename => '/var/www/html/acknowledge.html', die_on_bad_params => 0);
$template->param(FNAME          => $firstName);
$template->param(NAME           => $firstName . " " . $lastName);
$template->param(EMAIL          => $email);
$template->param(AFFILIATION    => $affiliation);

到目前为止，我发现的唯一两种方法如下:

1 - HTML::Template 有一个名为 vanguard_compatibility_mode 的开关...来自 perldocs

vanguard_compatibility_mode - if set to 1 the module will expect to see s that look like %NAME% in addition to the standard syntax. Also sets die_on_bad_params => 0. If you're not at Vanguard Media trying to use an old format template don't worry about this one. Defaults to 0.

2 - HTML::Template 还支持在注释 block 中嵌入模板标签，以便您的代码符合 HTML 标准，如下所示:<!-- TMPL_NAME NAME=FNAME -->

再次来自 perldocs:

If you're a fanatic about valid HTML and would like your templates to conform to valid HTML syntax, you may optionally type template tags in the form of HTML comments. This may be of use to HTML authors who would like to validate their templates' HTML syntax prior to HTML::Template processing, or who use DTD-savvy editing tools.

<!-- TMPL_VAR NAME=PARAM1 -->

第二个选项最初对我不起作用，直到我设置了 die_on_bad_params => 0对于构造函数。
