Question

I’m trying to do an if statement with data passed to the twig file from the controller. Below is a line from the controller:

return $this->redirect($this->generateUrl('homepage', array('user' => $user, 'contact' => $contact)));

My goal is to do an if statement with the variable ‘contact’. I checked the twig reference and it shows how to do an if statement but that would not work with ‘contact’. Below is the code I tried, can somebody tell me what I’m doing wrong?

{% if {{ contact.id }} > 0 %}
   {{ contact.addrLineOne }}
{% else %}
   --
{% endif %}

You’re almost there, just a small syntax modification will make your code working!

{% if contact.id > 0 %}
   {{ contact.addrLineOne }}
{% else %}
   --
{% endif %}

In Twig, curly braces means that you want to print the value of a variable or an expression. So you’re statement in PHP would look like this :

if ((echo contact[id]) > 0)
    echo contact[addrLineOne]; // or contact->addrLineOne() according to the context
else
    --
