检查变量是否是Twig的日期

Question

I have an array of variables that I want to display in a Twig template and each variable can be either a string or a date.

If the variable is a date, I want to apply the date filter like this:

{{ my_var|date('d/m/Y') }}

And if it's a string I want it to display it the usual way:

{{ my_var }}

Is there any way to test if a variable is a date (ie. an instance of the PHP DateTime object)?

Answer 1

Maybe not the best way to do it, but I found a solution to my problem.

{% if my_var.timestamp is defined %}
    {{ my_var|date('m/d/Y') }}
{% else %}
    {{ my_var }}
{% endif %}

As a DateTime PHP object has a public getTimestamp method, it's a way to check if the variable is a date whether this property is set or not.
