我正在尝试创建自己的Twig过滤器.我跟着这个tuto
Symfony Official Book.
但我收到此错误src / Acme / Bundle / StoryBundle / Resources / views / Story / storyList.html.twig中不存在过滤器“avatar”
这是我的AvatarExtension.php
<?php
namespace AppBundle\Twig;
class AvatarExtension extends \Twig_Extension
{
public function getFilters()
{
return array(
new \Twig_SimpleFilter('avatar', array($this, 'avatar')),
);
}
public function getName()
{
return 'avatar_extension';
}
public function avatar($user)
{
if ($user->getPicture() && $user->getPicture() != '') {
return $user->getPicture();
} else {
return '/images/default-avatar.jpg';
}
}
}
还有我的AppBundle / Resources / config / services.yml
services:
app.twig.avatar_extension:
class: AppBundle\Twig\AvatarExtension
tags:
– { name: twig.extension }
使用过滤器的模板与Twig扩展名不在同一个包中,但由于它是一项服务,因此它应该不是问题.
以下是我的称呼方式:{{story.author | avatar}}
你知道问题可能是什么吗?
编辑
# Twig Configuration
twig:
debug: "%kernel.debug%"
strict_variables: "%kernel.debug%"
globals:
uploadTmpDir: %upload.tmp.relative.dir%
最佳答案 好的,我找到了解决方案.这是services.yml
app.twig.avatar_extension:
class: AppBundle\Twig\AvatarExtension
tags:
- { name: twig.extension }
这是ExtensionClass:
<?php
namespace AppBundle\Twig;
class AvatarExtension extends \Twig_Extension
{
public function getFilters()
{
return array(
new \Twig_SimpleFilter('avatar', array($this, 'avatarFilter')),
);
}
public function avatarFilter($user)
{
if ($user->getPicture() && $user->getPicture() != '') {
return $user->getPicture();
} else {
return '/images/default-avatar.jpg';
}
}
public function getName()
{
return 'avatar_extension';
}
}
我想函数名必须有Filter后缀
