Own Twig Extension

tip

Our DevTools Plugin does this!

Creating twig-extensions is very simple. First of all, create a folder in your Plugin/src folder. You can name this as you like, but for simplicity, we'll call it "TwigExtension". Create a new php file in it, too.

src
- Twigextension
  - MyTwigExtension.php

Fill it with this template:

Click to expand

<?php

namespace <plugin>\TwigExtension;

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

class MyTwigExtension extends AbstractExtension
{
    public function getFunctions()
    {
        return [
            new TwigFunction('myMethod', [$this, 'myMethod'])
        ]
    }
    
    public function myMethod($value)
    {
        //do stuff
        return $value;
    }
}

?> To create a TwigFilter instead, you need to call the getFilters() instead. Here you add a new TwigFilter(). Other than that, it's the same Syntax!

Then, add your code and register the class in your services.xml. Here, you can also inject repositories and services!

<service id="<plugin>\TwigExtension\MyTwigExtension">
    <tag name="twig.extension"/>
</service>

And that's it! Call it in Twig like this: {% myMethod(value) %}
