为什么智能模板引擎找不到我的模板文件？

为什么智能模板引擎找不到我的模板文件？

致命错误: Uncaught > Smarty:无法在第129行的C:\xampp\htdocs\testing\includes\smarty\sysplugins\smarty_internal_templatebase.php中加载模板文件'test.tpl‘<-

$smarty->testInstall();也做了

Smarty Installation test...
Testing template directory...
C:\xampp\htdocs\testing\templates\frontend\default\tpl is OK.
Testing compile directory...
C:\xampp\htdocs\testing\templates_c\frontend is OK.
Testing plugins directory...
C:\xampp\htdocs\testing\includes\smarty\plugins is OK.
Testing cache directory...
C:\xampp\htdocs\testing\cache is OK.
Testing configs directory...
C:\xampp\htdocs\testing\configs is OK.
Testing sysplugin files...
... OK
Testing plugin files...
... OK
Tests complete.

和var_dump($smarty->getTemplateDir());

数组(1){ "C:/xampp/htdocs/testing/templates/frontend/default/tpl\“字符串(55) => }

尽管调试这一点令人困惑，但实际上是全局变量$smarty的一个简单问题，它最初是在configs.php中设置的Smarty对象，在包含test.php时再次被覆盖。Smarty失去了其配置的$template_dir，因为对象$smarty被重新初始化为默认值。模板的默认位置是在./templates中查找，这就是它使用C:/xampp/htdocs/testing/templates/test.tpl的原因。

解决方案:只是不要在$smarty = new Smarty();中执行test.php

test.php

<?php

//$success = 'Success Message';
//$error = 'Error Message';
$errors[] = 'Error one';
$errors[] = 'Error two';

// Don't do this:  $smarty is already initialized and configured.
// $smarty = new Smarty;

$smarty->assign('errors', $errors);
$smarty->display('test.tpl');
