我在我的应用中收到此错误,但无法找到我失败的地方:
尝试调用函数"替换"来自全局命名空间。
这是Stacktrace:
[1] Symfony\Component\Debug\Exception\UndefinedFunctionException: Attempted to call function "replace" from the global namespace.
at n/a
in /var/www/html/reptooln_admin/app/cache/dev/twig/eb/76/c3cb3f071f775598b83974700b4a2523941a76b0f3cf8801d01d9210eae0.php line 318
现在在我的代码中我定义了这个Twig扩展:
services:
app.twig.extension:
class: AppBundle\Extension\AppTwigExtension
tags:
- { name: twig.extension }
这是班级:
<?php
namespace AppBundle\Extension;
class AppTwigExtension extends \Twig_Extension
{
public function getFilters()
{
return array(
'var_dump' => new \Twig_Filter_Function('var_dump'),
'empty' => new \Twig_Filter_Function('empty', array($this, 'is_empty')),
'isset' => new \Twig_Filter_Function('isset', array($this, 'is_set')),
'isnull' => new \Twig_Filter_Function('isnull', array($this, 'is_null')),
'ucfirst' => new \Twig_Filter_Function('ucfirst', array($this, 'uc_first')),
'ucwords' => new \Twig_Filter_Function('ucwords', array($this, 'uc_words')),
'count' => new \Twig_Filter_Function('count', array($this, 'co_unt')),
'sizeof' => new \Twig_Filter_Function('sizeof', array($this, 'size_of')),
'concat' => new \Twig_Filter_Function('concat', array($this, 'concat')),
'in_array' => new \Twig_Filter_Function('in_array', array($this, 'inarray')),
'array' => new \Twig_Filter_Function('array', array($this, 'array_')),
'add_to_array' => new \Twig_Filter_Function('add_to_array', array($this, 'add_to_array')),
'replace' => new \Twig_Filter_Function('replace', array($this, 'replace')),
'htmlentitydecode' => new \Twig_Filter_Function('htmlentitydecode', array($this, 'htmlentitydecode')),
);
}
public function replace($subject, $search, $replace)
{
return str_replace($search, $replace, $subject);
}
// functions goes here
public function getName()
{
return 'app_twig_extension';
}
}
有什么问题?我找到了this帖子但在我的案例中没有帮助
答案 0 :(得分:4)
从错误中,您似乎注册了一个名为replace
的过滤器,但您尝试将其称为函数。
所以这应该已经有效(但我认为这不是你想做的):
{{ my_variable|replace('something', 'with', 'this') }}
我认为你要做的是:
{{ replace(my_variable, 'replace', 'this') }}
要注册一个函数,请在getFunctions
类中添加一个名为AppTwigExtension
的方法,并将replace
定义移到该类。有关详细信息,请参阅documentation。
