How to properly loop three dimensional array in twig?

loops, multidimensional-array, php, twig

Solution

With the help of vijay4vijju and his reference to `dump` I was able to loop over the array.

Only a single loop was needed:

{% for key,val in hash %}
  <tr>
    <td>{{ val.key1 }}</td>
    <td>{{ val.key2 }}</td>
    <td>{{ val.key3 }}</td>
    <td>{{ val.key4 }}</td>
  </tr>
{% endfor %}

I would have selected his answer but it technically wasn't the answer, and dump was just a reference to the `dump` manual.

To enable debugging in twig I used:

$twig = new Twig_Environment($loader, array(
    'debug' => true,
));
$twig->addExtension(new Twig_Extension_Debug());

To troubleshoot this issue I used:

{% for key,val in hash %}
  <pre>{{ dump(val) }}</pre>
  <tr>
    <td>{{ val.key1 }}</td>
    <td>{{ val.key2 }}</td>
    <td>{{ val.key3 }}</td>
    <td>{{ val.key4 }}</td>
  </tr>
{% endfor %}

Problem

I have an array setup like so; and I cant seem to loop through the values with twig: ``` array (size=1) 'hash' => array (size=7) 0 => array (size=4) 'key1' => "val" 'key2' => "val" 'key3' => "val" 'key4' => "val" 1 => array (size=4) 'key1' => "val" 'key2' => "val" 'key3' => "val" 'key4' => "val" ... ``` The template code I'm using (in its nth iteration): ``` {% for i in hash %} {% for j in i %} <td>{{ j.key1 }}</td> <td>{{ j.key2 }}</td> <td>{{ j.key3 }}</td> <td>{{ j.key4 }}</td> {% endfor %} {% endfor %} ``` I keep getting `Array to string conversion` errors with the above twig template code.
