Describe the process of creating a custom Twig extension.

Describe the process of creating a custom Twig extension.

Minimal Steps to Create a Custom Twig Extension in Symfony:

  1. Create a Custom Twig Extension Class:

Example

<?php
// src/Twig/MyCustomExtension.php
namespace App\Twig;

use Twig\Extension\AbstractExtension;
use Twig\TwigFunction;

class MyCustomExtension extends AbstractExtension
{
    public function getFunctions()
    {
        return [
            new TwigFunction('my_custom_function', [$this, 'myCustomFunction']),
        ];
    }

    public function myCustomFunction($value)
    {
        return strtoupper($value);
    }
}

?>

Register the Extension as a Service:

In config/services.yaml, register your custom extension:

Example

services:
    App\Twig\MyCustomExtension:
        tags: ['twig.extension']

Use the Custom Function in Twig Template:

Example

{{ my_custom_function('hello world') }}
