I am trying out Jekyll to help someone who's not all that technical maintain their own static site. I would like to be able to have a images directory in the app's root /images containing images following a naming convention:
post_one_1.jpg, post_one_2.jpg, post_two_1.jpg, post_two_2.jpg ... etc.
I would then like for the user to create a post (post_one) and dynamically grab all of the images pertaining to that post from the images directory.
This plugin (https://gist.github.com/jgatjens/8925165) does almost exactly what I need, but isn't compatible with github pages.
Is there a solution in which I can hand the site off to a user and they would only need to add images to the image directory following the naming convention and then create a post and have access to the images?
Given you have a post file _posts/2015-05-28-post_one.md
From inside this post you have :
In order to extract post_one whe do :
{% assign imgNameStart = page.id | remove: page.dir | remove: "/" %}
We now generate the base path we search for :
{% assign imgBasePath = imgNameStart | prepend: "/images/" %}
in this case it will be imgBasePath = "/images/post_one"
Loop over all our static files (files that are not pages or posts).
{% for img in site.static_files %}
And print images that have /images/post_one in their path like /images/post_one-01.jpg or /images/post_one-wathever-you-want.jpg
{% if img.path contains imgBasePath %}
<img src="{{ site.baseurl }}{{ img.path }}">
{% endif %}
{% endfor %}
All together :
{% assign imgNameStart = page.id | remove: page.dir | remove: "/" %}
{% assign imgBasePath = imgNameStart | prepend: "/images/" %}
{% for img in site.static_files %}
{% if img.path contains imgBasePath %}
<img src="{{ site.baseurl }}{{ img.path }}">
{% endif %}
{% endfor %}
Beware of code indentation if your post is a markdown file, four space indentation can be transformed to code snippet.
