I have a self-joining table where each folder has a parent, and the depth of this is unlimited. One folder can have another folder as a parent, no restriction on the depth.
Today my code looks like this, and I am looking for a way of digging down as deep as it needs without hard-coding each step down, is there perhaps a way to define a twig function with a loop, that calls itself on each round in the loop?
<select id='parent' name='container'>
<option value='none'>No parent</option>
{% for folder in folders %}
<option value='{{ folder.id }}'>{{ folder.name }}</option>
{% for folder in folder.children %}
<option value='{{ folder.id }}'> {{ folder.name }}</option>
{% endfor %}
{% endfor %}
</select>
You need a separate file rendering options that recursively includes itself:
<select>
<option value="none">No parent</option>
{% include 'options.html.twig' with {'folders': folders, 'level': 0} %}
</select>
options.html.twig
:
{% for folder in folders %}
<option value="{{ folder.id }}">
{% for i in range(0, level) %} {% endfor %}
{{ folder.name }}
</option>
{% include 'options.html.twig' with {'folders': folder.children, 'level': level + 1} %}
{% endfor %}
I wrote this code right here, so don't expect it to be correct, but it should be enough to give you the idea.
