How Would You Make A Two Column Table With Twig?

Question

I can\'t for the life of me figure out how to add a every OTHER iteration in a Twig loop.

For instance:

$numArray = a         


        

Answer 1

For this specific case you can prepare your array before. So in a loop you will have in each row two variables. Try first example from this site http://twig.sensiolabs.org/doc/templates.html

Answer 2

The proper way of doing this is using the batch filter. It is new in 1.12.3.

<table>
{% for row in numArray|batch(2) %}
  <tr>
  {% for column in row %}
    <td>{{ column }}</td>
  {% endfor %}
  </tr>
{% endfor %}
</table>

Ref: http://twig.sensiolabs.org/doc/filters/batch.html

Answer 3

Something like this would work:

<table>
  <tr>
  {% for num in numArray %}
      <td>
        {{num}}
      </td>
  {% if loop.index is even %}
    </tr>
    <tr>
  {% endif %}
  {% endfor %}

  {% if num|length is odd %}
    <td></td>
  {% endif %} 
  </tr>
</table>

An alternative way, that feels much less hacky:

<table>
  {% for i in range(0, numArray|length-1, 2) %}
  <tr>
    <td>{{ numArray[i] }}</td>
    <td>{{ numArray[i+1]|default("") }}</td>
  </tr>
  {% endfor %}
</table>
