Is it possible to sort an array by key without twig extension ?
I have an array like this :
{key1 : object1, key2 : object2...)
When i use {% for t in tab|sort%}, it give me an array sort by object ID and not by the key.
No way to do this without twig extension ?
As far as I know, there isn't a filter to do the sort by array key.
However, in case if you need to create a filter, you can do like this in your extended Twig extensions file,
Create the function,
public function ksort($array) {
ksort($array);
return $array;
}
Hook the function in available filters,
public function getFilters() {
$this->filters['ksort'] = new \Twig_SimpleFilter('ksort', array($this, 'ksort'));
return $this->filters;
}
And to call the filter,
{% for a in array | ksort %}
<h2>{{ a }}</h2>
{% endfor %}
Cheers
