Access collections based on variable

[danielLee0721]

Hi there,

Is it possible to pass in variables to access collections?
ie. collections['someVariable']

I would like to be able to dynamically loop through collections based on a front matter variable.

Any help would be greatly appreciated!

Thank you,
D

collections['someVariable'] should work, if I remember correctly.
Where are you trying to use a dynamic collection name that the syntax wasn't working?

Thank you for the reply!

What I am trying to do is make an index page showing a list of links to all pages with a certain tag
So if I have a number of pages with the tag
tags: ['face'];

and then on my page I do

---
layout: index-list-page.html
type: face
---

and on the 'index-list-page' layout page I do

---
layout: default.html
---
<div class="container">
  <ul class="index-list">
    {%- assign indexList = collections['type'] -%}
    {%- for i in indexList -%}
    <li>{{ i.url }}</li>
    {%- endfor -%}
  </ul>
</div>
{{ content }}

I was hoping that the layout page would be able to receive the 'type' variable from the template page.
Is this possible?

I was just poking at this, and here is my minimal sample:

---
title: HOME
permalink: /
collectionName: posts
---

<h1>Posts</h1>

{% for p in collections[collectionName] %}
<p>{{ p.data.title }}</p>
{% endfor %}

Ah, but I see you just posted a comment... Yeah, you're really close! instead of collections['type'], it should be collections[type] (without the nested quotes). If you use quotes around 'type', it will look for a collection named "type" (collections.type) instead of collections.face.

Sorry, after seeing your response and sample code, I guess my initial reply from 18 hours ago was pretty confusing.

Omg it worked! Thank you so much!! I thought I tried doing it without the '' but I guess not.
