Symfony 2 Twig 扩展
我想添加我自己的 twig 功能并在 Symfony 2 中添加新的 twig 扩展。
为此，我创建了这些文件夹： src/Ptracker/TasksBundle/Twig 和 src/Ptracker/TasksBundle/Twig/Extension 并将文件 myTwigExtension.php 放入其内容如下：
<?php
namespace Ptracker\TasksBundle\Twig\Extension;
class MyTwigExtension extends \Twig_Extension {
public function getFilters() {
return array(
'var_dump' => new \Twig_Filter_Function('var_dump'),
'linkable' => new \Twig_Filter_Method($this, 'linkable'),
);
}
public function linkable($sentence, $expr) {
return 'it works!!';
}
public function getName()
{
return 'my_twig_extension';
}
}
?>
我还添加了一些代码src/Ptracker/TasksBundle/Resources/config/services.yml ：
services:
ptracker.twig.extension:
class: Ptracker\TasksBundle\Twig\Extension\MyTwigExtension
tags:
- { name: twig.extension }
重点是我总是遇到同样的致命错误：
Fatal error: Class 'Ptracker\TasksBundle\Twig\Extension\MyTwigExtension' not found in /home/renat/www/ptracker/app/cache/dev/appDevDebugProjectContainer.php on line 1092
我做错了什么？我花了好几个时间来解决这个问题，尝试将扩展文件放在不同的文件夹中，更改命名空间..没有任何帮助。
请帮我 ：）
I want to add my own twig functionality and to add new twig extension in Symfony 2.
To do that i created these folders: src/Ptracker/TasksBundle/Twig and src/Ptracker/TasksBundle/Twig/Extension and put file myTwigExtension.php in it with this content:
<?php
namespace Ptracker\TasksBundle\Twig\Extension;
class MyTwigExtension extends \Twig_Extension {
public function getFilters() {
return array(
'var_dump' => new \Twig_Filter_Function('var_dump'),
'linkable' => new \Twig_Filter_Method($this, 'linkable'),
);
}
public function linkable($sentence, $expr) {
return 'it works!!';
}
public function getName()
{
return 'my_twig_extension';
}
}
?>
Also i added some code to src/Ptracker/TasksBundle/Resources/config/services.yml :
services:
ptracker.twig.extension:
class: Ptracker\TasksBundle\Twig\Extension\MyTwigExtension
tags:
- { name: twig.extension }
The point is that i ALWAYS get the same fatal error:
Fatal error: Class 'Ptracker\TasksBundle\Twig\Extension\MyTwigExtension' not found in /home/renat/www/ptracker/app/cache/dev/appDevDebugProjectContainer.php on line 1092
What am i doing wrong? I've spent several ours to fix this problem, tried to put extension file in different folders, changed namespace.. nothing helps.
Please help me :)

文件名在 Linux 上区分大小写，并且找不到任何内容，因为它尝试加载
../MyTwigExtension.php。将文件重命名为MyTwigExtension.php。File names are case-sensitive on linux and it doesn't find anything because it tries to load
../MyTwigExtension.php. Rename your file toMyTwigExtension.php.
