我必须根据用户所处的状态显示不同的医疗表格。还有一个许多州共享的默认表格。这些医疗表格都是用模板工具包编写的,它们包含在更大的模板中。状态可用作标准化形式的变量。

如果存在,我需要选择特定于状态的模板,否则回退到默认值。我最好怎么做呢?

INCLUDE_PATH已被用于控制站点样式之间的切换。

像这样的东西应该可以完成这项工作:

主.tt:

This is a main template [% GET state %]
[% SET iname = state _ ".tt" %]
[% TRY %]
[% INCLUDE "$iname" %]
[% CATCH %]
[% INCLUDE default.tt %]
[% END %]
End of main template

默认.tt:

This is default template

s1.tt:

This is template for state s1.

t.pl:

#! /usr/bin/perl
use 5.006;
use strict;
use warnings;

use Template;
my $tt = Template->new();
$tt->process("main.tt", { state => "s1" })
  || die $tt->error, "\n";
print "---------\n";
$tt->process("main.tt", { state => "unknown" })
  || die $tt->error, "\n";

运行时t.pl

This is a main template s1
This is template for state s1.
End of main template
---------
This is a main template unknown
This is default template
End of main template
