How to Decode JSON in Twig?

Decoding JSON in Twig

Decoding JSON in Twig is possible with the help of custom Twig extensions. Here's how you can do it:

Step 1: Create the Extension Class

namespace Acme\DemoBundle\Twig\Extension;

use Symfony\Component\DependencyInjection\ContainerInterface;  
use \Twig_Extension;

class VarsExtension extends Twig_Extension
{
    protected $container;
 
    public function __construct(ContainerInterface $container) 
    {
        $this->container = $container;
    }
      
    public function getName() 
    {
        return 'some.extension';
    }
    
    public function getFilters() {
        return array(
            'json_decode'   => new \Twig_Filter_Method($this, 'jsonDecode'),
        );
    }

    public function jsonDecode($str) {
        return json_decode($str);
    }
}
Copy after login

Step 2: Register the Extension

Add this to your Services.xml file:

<service>
Copy after login

Step 3: Use the Extension

In your Twig template, you can use the | json_decode filter like this:

{% set obj = form_label(category) | json_decode %}
Copy after login

This will decode the JSON string in the form_label(category) variable and assign the decoded object to obj.
