I have a problem, in Controller I have a multidimensional array, but I don't know how many dimensional this array is. It is dynamically and determined by database, so can I put it to twig in any way?
When I'm using function dump in twig, it displays:
array(5) {
[0]=> int(50)
[1]=> int(51)
[2]=> int(52)
[51]=> array(2) {
[0]=> int(55)
[55]=> array(1) {
[0]=> int(56)
}
}
[52]=> array(2) {
[0]=> int(53)
[1]=> int(54)
}
}
Okay, you can do that like this: (if you know your array has only one more dimension, total 2 dimensions).
{% for key, item in items %}
{% if item is iterable %}
{% for sub_item in item %}
Do something...
{% endfor %}
{% else %}
Do something else...
{% endif %}
{% endfor %}
If you have a multidimensional array that has more than 1 sub array, you have to call a function recursively to reach that other sub dimensions. You can do it in your twig extension file.
A recursive function is calling itself to reach sub items in a multidimensional array. I don't know what do you want to do with that array but i'm gonna make a basic function depends on your array.
function recursiveTwig($array)
{
foreach($array as $key => $value){
if(is_array($key)) {
$this->recursiveTwig($key);
} else {
//Do something with your value...
}
}
}
