IF == true OR b == true statement

Question

I cannot find a way to get TWIG to interpret the following conditional statement:

{% if a == true or b == true %} do stuff {% endif %} 

Am I missing something or is it impossible?

Answer 1

Check out this Twig Reference .

You can do it this simple:

 {% if (a or b) %} ... {% endif %} 

Answer 2

Comparison expressions must be in their brackets:

 {% if (a == 'foo') or (b == 'bar') %} ... {% endif %} 

Alternative if you are checking one variable and the number of possible values:

 {% if a in ['foo', 'bar', 'qux'] %} ... {% endif %}
