README

Adds InstanceOf Expression as Twig Extension. When you want to check for a specific type of variable in a twig template.

Prerequisites

• PHP 8.0+
• Symfony 5.4 or 6.x
• Twig 3.x

Installation

1. Install this Symfony bundle with composer:

   composer require lelyfoto/twig-instanceof

2. Make sure the bundle is added to config/bundles.php:

   return [
       // ...
       Lelyfoto\Twig\InstanceOf\TwigInstanceOfBundle::class => ['all' => true],
       // ...
   ];   
   

Usage

Important to note that when testing for a class that you must use quotes and escaping inside the twig templates.

{% if testObject is instanceof('\\Example\\TestInterface') %}
    Do something with {{ testObject.show() }}
{% endif %}

Use without Symfony

use Twig\Environment;
use Lelyfoto\Twig\InstanceOf\InstanceOfExtension;

$twig = new Environment($loader);
$twig->addExtension(new InstanceOfExtension());
