Passing an image as an element in an array

Support
1

I’m new to Zola and I’ve done a lot of reading and it seems like there is no way to create a custom variable for something like an image or author. This is my work around, but I need someones help. I’ve almost got it, but not quit there yet.

In the YAML section I have description, and within that description I can put author, picture.jpg, description, or whatever I want. It’s just a string. So I do this…
+++
title = “My cool page”
description =“picture.jpg~Author Name~My super cool description goes here”
+++

Now on my html page where I want this to display I do this:{{ “picture.jpg~John Doe~This is my description” | split(pat="~") }}

This outputs an array with 3 elements
[picture.jpg, John Doe, This is my description]

So far so good! But this is where I’m stuck! How do I reference each element? Like this…
[0] picture.jpg
[1] John Doe
[2] This is my description

The array must have a name and I assume I reference the elements within the array like this: array_name[1]. But I dont know how to do that. Like everything in life, it’s probably super simple, once you know how. I just dont know how.

Eventually I would like to do this:
(that didn’t work, I cant post code)

Thanks in advance!!

  1. Why not put that info in [extra]? That’s what it’s for.
  2. You need to assign it to a variable

{% set data = “picture.jpg~John Doe~This is my description” | split(pat="~") %}

Thanks so much keats! This works like a champ! Exactly what I was looking for.

However, this does not work:
{% set data = page.description | split(pat=“~”) %}
{{ data[0] }} should return picture.jpg

I get the error:
Variable data[0] not found in context while rendering ‘page.html’: the evaluated version was data.0. Maybe the index is out of bounds?

I’m still missing something?

You mentioned using [extra], I dont see how that would work? For example within each page (content/news/somefile.md) I have a single and unique image as well as an author (that is not unique). I assume I might be able to use [extra] to define a set or an array of authors since they are fixed. But defining a unique image file, I just dont see how that would work? This is why I choose to put everything as a string in page.description, and just split the string on some unique and pre-defined unique character.
Thanks

Under [extra] you can add your own fields to the page, and they’ll function just like any other.

So, instead of

 +++
 title = “My cool page”
 description =“picture.jpg~Author Name~My super cool description goes here”
 +++

you can go for

 +++
 title = “My cool page”
 description =“My super cool description goes here”
 author = "Stephen King"

 [extra]
 image = "foo.jpg"
 +++

and skip the hacky tilde split.
