How do I check what type my variable of (string, integer, boolean, array, dictionary, etc)?

    Your solution may be the best one so far. It looks as if Twig has rejected adding this feature as it doesn't fall inline with the goals of Twig. github.com/fabpot/Twig/issues/595

I needed this feature today, so I've put together a simple plugin, which does the job: Craft-TwigTypeTest


{% set test_var = craft.entries %}

{% if test_var is of_type('object') %}
{% endif %}


{% set test_var = craft.entries %}

{{ test_var|get_type }}
{# Outputs: object #}

To my knowledge this is not possible natively in Twig. Depending on your situation / template needs here are some useful tests

{% if foo is iterable %}

Array or object

{% if foo is same as(true) %}

Basically identical to using === in php


I recently needed to check if a variable is a number. My first idea was to use the divisibleby test:

{% if var is divisible by(1) %}
{% endif %}

Unfurtunatelly twig returns true for every string passed to it.

But what you can do is to use regular expressions using the matches operator in the comparison. You'll note that I double escaped the dot and the meta-character \d, this is because of a twig bug (or put otherwise: wrong documentation of using regex here).

{# Match integer #}
{% if var matches '/^\\d+$/' %}
{% endif %}

{# Match floating point number #}
{% if var matches '/^[-+]?[0-9]*\\.?[0-9]+$/' %}
{% endif %}

I hit a snag for this where I needed to check if a value was a boolean type. This isn't the greatest approach, but it does work and is easy to interpret:

{% if value is same as(false) or value is same as(true) %}
