Twig - How to check if variable is a number / integer
At last found something. One of the answers from:https://craftcms.stackexchange.com/questions/932/how-to-check-variable-type
{# Match integer #}{% if var matches '/^\\d+$/' %}{% endif %}{# Match floating point number #}{% if var matches '/^[-+]?[0-9]*\\.?[0-9]+$/' %}{% endif %}
You can create a twig extension to add a test "numeric"
With that, you'll be able to write :
{% if foo is numeric %}...{% endif %}Create your extension class :
namespace MyNamespace;class MyTwigExtension extends \Twig_Extension{ public function getName() { return 'my_twig_extension'; } public function getTests() { return [ new \Twig_Test('numeric', function ($value) { return is_numeric($value); }), ]; }}And in your configuration :
services: my_twig_extension: autowire: true class: AppBundle\MyNamespace\MyTwigExtension tags: - { name: twig.extension }See documentation :
