PHP basename Twig 等价物 [英] PHP basename Twig equivalent

问题描述

在 Twig 中是否有与 PHP basename() 等效的函数?

Is there an equivalent function to PHP basename() in Twig ?

类似于:

$file = basename($path, ".php");

推荐答案

默认情况下，Twig 中没有默认的 basename 过滤器样式，但是如果您需要扩展默认的 Twig 过滤器或函数你自己的，你可以按照你的 Symfony 版本的说明书中的描述创建一个扩展.http://symfony.com/doc/current/cookbook/templating/twig_extension.html

By default there is no default basename style of filter in Twig, but if you need to extend the default Twig filters or functions with your own, you can create an extension as described in the cookbook for your version of Symfony. http://symfony.com/doc/current/cookbook/templating/twig_extension.html

树枝扩展

// src/AppBundle/Twig/TwigExtension.php
namespace AppBundle\Twig;

class TwigExtension extends \Twig_Extension
{

    public function getName()
    {
       return 'twig_extension';
    }

    public function getFilters()
    {
       return [
           new \Twig_SimpleFilter('basename', [$this, 'basenameFilter'])
       ];
    }

    /**
     * @var string $value
     * @return string
     */
    public function basenameFilter($value, $suffix = '')
    {
       return basename($value, $suffix);
    }
}

配置文件

# app/config/services.yml
services:
    app.twig_extension:
        class: AppBundle\Twig\TwigExtension
        public: false
        tags:
            - { name: twig.extension }

树枝模板

{% set path = '/path/to/file.php' %}
{# outputs 'file.php' #}
{{ path|basename }}

{# outputs 'file' #}
{{ path|basename('.php') }}

{# outputs 'etc' #}
{{ '/etc/'|basename }}


{# outputs '.' #}
{{ '.'|basename }}

{# outputs '' #}
{{ '/'|basename }}
